define gstring in terms of gchar*. this typedef reflects the type name of Fri Jun 23 17:20:26 2000 Tim Janik <timj@gtk.org> * glib.h: define gstring in terms of gchar*. this typedef reflects the type name of the primitive G_TYPE_STRING in the gobject module. Sat Jun 24 23:03:04 2000 Tim Janik <timj@gtk.org> * gtype.[hc]: provide G_TYPE_CHAR, G_TYPE_UCHAR, G_TYPE_BOOLEAN, G_TYPE_INT, G_TYPE_UINT, G_TYPE_LONG, G_TYPE_ULONG, G_TYPE_FLOAT, G_TYPE_DOUBLE and G_TYPE_STRING fundamental types. added a GTypeValueTable* pointer to GTypeInfo structure for types to implement GValue handling functions. GTypeValueTable contains the following members: value_init(): initialize a GValue structure. value_free(): free GValue structure contents (optional). value_copy(): copy one GValue contents to another GValue structure of collect_type: varargs collection type for the first variable argument to be collected by collect_value(). collect_value(): variable arguments collection function (optional). lcopy_type: varargs collection type for the first variable argument to be location copyied by lcopy_value(). lcopy_value(): variable arguments location copy function (optional). g_type_value_table_peek(): new function to retrive the GTypeValueTable* for a type node. ValueTables get inherited from parent types, unless overridden through the GTypeInfo structure. internally, GTypeValueTable support means an added overhead of one pointer per static or used dynamic type node. g_type_add_class_cache_func(): provide a cache_func/data pair to be called prior to a type nodes last_unref() function, this can be used to prevent premature class destruction. multiple installed cache_func() will be chained upon last_unref() untill one of them returns TRUE. the cache_func()s have to check the type id passed in to figure whether they actually wants to cache the class of this type (since any types are routed through the cache_func() chain). g_type_remove_class_cache_func(): remove a previously installed cache_func/data pair. the cache maintained by this function has to be clear when calling g_type_remove_class_cache_func() to avoid leaks. g_type_class_unref_uncached(): class unref function for cache_func() implementations, unreferences a class omitting the cache chain (and therefore unref->cache->unref->... loops). * gvaluetypes.[hc]: provide the value setters/getters for the primitive fundamental types boolean, char, uchar, int, uint, long, ulong, float, double and string. * gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a GTypeValueTable is provided for this type. removed g_value_init_default(), g_value_validate(), g_value_defaults(), g_value_set_default() and g_values_cmp() as these are supplied by the GParamSpec API now. moved g_values_exchange() into the "implementation details" section, since it just provides the underlying functionality for g_value_convert(). * gvaluecollector.h: renamed the varargs value container from GParamCValue to GTypeCValue as the value collection methods are supplied by the type system now. G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a GParamSpec structure now. * genums.h: macros cleanups/fixes. * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type and assorted g_value_{s|g}et_{enum|flags}() implementations. * gobject.[hc]: provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods and g_value_{s|g}et_object(). * gparam.[hc]: reduced class to value_set_default(), value_validate() and values_cmp(). also parameters now need to fill in a GType value_type; field to indicate the GValue type they are handling. provide g_param_value_set_default(), g_param_value_defaults(), g_param_value_validate() and g_param_values_cmp(). * gparamspecs.[hc]: got rid of the g_value_* functions and the G_IS_VALUE_* macros. adapted param spec implementations according to the GParamSpecClass changes.

/* GObject - GLib Type, Object, Parameter and Signal Library
changed prototype of g_boxed_type_register_static() to contain an optional Wed Mar 7 09:36:33 2001 Tim Janik <timj@gtk.org> * gboxed.[hc]: changed prototype of g_boxed_type_register_static() to contain an optional init function and a hint at whether the boxed structure uses ref counting internally. added g_value_set_boxed_take_ownership(). made G_TYPE_BOXED an abstract value type. * genums.[hc]: made G_TYPE_ENUM and G_TYPE_FLAGS abstract value types. * glib-genmarshal.c: argument type changes, preparation for third-party arg specification. * gobject.[hc]: cleaned up get/set property code. added g_strdup_value_contents() to improve warnings. * gparam.[hc]: added g_param_value_convert(), taking over responsibility of the old g_value_convert(). added G_PARAM_LAX_VALIDATION flag so validation alterations may be valid a part of the property setting process. * gparamspecs.[hc]: made value comparisons stable (for sort applications). added GParamSpecValueArray, a param spec for value arrays and GParamSpecClosure. nuked the value exchange functions and GParamSpecCCallback. * gtype.[hc]: catch unintialized usages of the type system with g_return_val_if_uninitialized(). introduced G_TYPE_FLAG_VALUE_ABSTRACT to flag types that introduce a value table, but can't be used for g_value_init(). cleaned up reserved type ids. * gvalue.[hc]: code cleanups and saner checking. nuked the value exchange API. implemented value transformations, we can't really "convert" values, rather transforms are an anylogy to C casts, real conversions need a param spec for validation, which is why g_param_value_convert() does real conversions now. * gvaluearray.[hc]: new files that implement a GValueArray, a struct that can hold inhomogeneous arrays of value (to that extend that it also allowes undefined values, i.e. G_VALUE_TYPE(value)==0). this is exposed to the type system as a boxed type. * gvaluetransform.c: new file implementing most of the former value exchange functions as single-sided transformations. * gvaluetypes.[hc]: nuked G_TYPE_CCALLBACK, added g_value_set_string_take_ownership(). * *.h: s/G_IS_VALUE_/G_VALUE_HOLDS_/. * *.[hc]: many fixes and cleanups. * many warning improvements. Tue Feb 27 18:35:15 2001 Tim Janik <timj@gtk.org> * gobject.c (g_object_get_valist): urg, pass G_VALUE_NOCOPY_CONTENTS into G_VALUE_LCOPY(), this needs proper documenting. * gparam.c: fixed G_PARAM_USER_MASK. * gtype.c (type_data_make_W): (type_data_last_unref_Wm): fixed invalid memory freeing. * gobject.c (g_object_last_unref): destroy signal handlers associated with object, right before finalization. * gsignal.c (g_signal_parse_name): catch destroyed nodes or signals that don't actually support details. * gobject.[hc]: got rid of property trailers. nuked GObject properties "data" and the "signal" variants. (g_object_connect): new convenience function to do multiple signal connections at once. (g_object_disconnect): likewise, for disconnections. * gparam.[hc] (g_param_spec_pool_lookup): took out trailer support. * gvalue.[hc]: marked g_value_fits_pointer() and g_value_peek_pointer() as private (the latter got renamed from g_value_get_as_pointer()). Wed Mar 7 09:32:06 2001 Tim Janik <timj@gtk.org> * glib-object.h: add gvaluearray.h. * gstring.[hc]: fixup naming of g_string_sprint*. * gtypes.h: fixed GCompareDataFunc naming. Wed Mar 7 09:33:27 2001 Tim Janik <timj@gtk.org> * gobject/Makefile.am: shuffled rules to avoid excessive rebuilds. * gobject/gobject-sections.txt: updates. * gobject/tmpl/*: bunch of updates, added another patch from Eric Lemings <eric.b.lemings@lmco.com>.

Tue Feb 27 18:35:15 2001 Tim Janik <timj@gtk.org> * gobject.c (g_object_get_valist): urg, pass G_VALUE_NOCOPY_CONTENTS into G_VALUE_LCOPY(), this needs proper documenting. * gparam.c: fixed G_PARAM_USER_MASK. * gtype.c (type_data_make_W): (type_data_last_unref_Wm): fixed invalid memory freeing. * gobject.c (g_object_last_unref): destroy signal handlers associated with object, right before finalization. * gsignal.c (g_signal_parse_name): catch destroyed nodes or signals that don't actually support details. * gobject.[hc]: got rid of property trailers. nuked GObject properties "data" and the "signal" variants. (g_object_connect): new convenience function to do multiple signal connections at once. (g_object_disconnect): likewise, for disconnections. * gparam.[hc] (g_param_spec_pool_lookup): took out trailer support. * gvalue.[hc]: marked g_value_fits_pointer() and g_value_peek_pointer() as private (the latter got renamed from g_value_get_as_pointer()). Wed Mar 7 09:32:06 2001 Tim Janik <timj@gtk.org> * glib-object.h: add gvaluearray.h. * gstring.[hc]: fixup naming of g_string_sprint*. * gtypes.h: fixed GCompareDataFunc naming. Wed Mar 7 09:33:27 2001 Tim Janik <timj@gtk.org> * gobject/Makefile.am: shuffled rules to avoid excessive rebuilds. * gobject/gobject-sections.txt: updates. * gobject/tmpl/*: bunch of updates, added another patch from Eric Lemings <eric.b.lemings@lmco.com>.

ValueTables get inherited from parent types, unless overridden through the GTypeInfo structure. internally, GTypeValueTable support means an added overhead of one pointer per static or used dynamic type node. g_type_add_class_cache_func(): provide a cache_func/data pair to be called prior to a type nodes last_unref() function, this can be used to prevent premature class destruction. multiple installed cache_func() will be chained upon last_unref() untill one of them returns TRUE. the cache_func()s have to check the type id passed in to figure whether they actually wants to cache the class of this type (since any types are routed through the cache_func() chain). g_type_remove_class_cache_func(): remove a previously installed cache_func/data pair. the cache maintained by this function has to be clear when calling g_type_remove_class_cache_func() to avoid leaks. g_type_class_unref_uncached(): class unref function for cache_func() implementations, unreferences a class omitting the cache chain (and therefore unref->cache->unref->... loops). * gvaluetypes.[hc]: provide the value setters/getters for the primitive fundamental types boolean, char, uchar, int, uint, long, ulong, float, double and string. * gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a GTypeValueTable is provided for this type. removed g_value_init_default(), g_value_validate(), g_value_defaults(), g_value_set_default() and g_values_cmp() as these are supplied by the GParamSpec API now. moved g_values_exchange() into the "implementation details" section, since it just provides the underlying functionality for g_value_convert(). * gvaluecollector.h: renamed the varargs value container from GParamCValue to GTypeCValue as the value collection methods are supplied by the type system now. G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a GParamSpec structure now. * genums.h: macros cleanups/fixes. * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type and assorted g_value_{s|g}et_{enum|flags}() implementations. * gobject.[hc]: provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods and g_value_{s|g}et_object(). * gparam.[hc]: reduced class to value_set_default(), value_validate() and values_cmp(). also parameters now need to fill in a GType value_type; field to indicate the GValue type they are handling. provide g_param_value_set_default(), g_param_value_defaults(), g_param_value_validate() and g_param_values_cmp(). * gparamspecs.[hc]: got rid of the g_value_* functions and the G_IS_VALUE_* macros. adapted param spec implementations according to the GParamSpecClass changes.

Tue Feb 27 18:35:15 2001 Tim Janik <timj@gtk.org> * gobject.c (g_object_get_valist): urg, pass G_VALUE_NOCOPY_CONTENTS into G_VALUE_LCOPY(), this needs proper documenting. * gparam.c: fixed G_PARAM_USER_MASK. * gtype.c (type_data_make_W): (type_data_last_unref_Wm): fixed invalid memory freeing. * gobject.c (g_object_last_unref): destroy signal handlers associated with object, right before finalization. * gsignal.c (g_signal_parse_name): catch destroyed nodes or signals that don't actually support details. * gobject.[hc]: got rid of property trailers. nuked GObject properties "data" and the "signal" variants. (g_object_connect): new convenience function to do multiple signal connections at once. (g_object_disconnect): likewise, for disconnections. * gparam.[hc] (g_param_spec_pool_lookup): took out trailer support. * gvalue.[hc]: marked g_value_fits_pointer() and g_value_peek_pointer() as private (the latter got renamed from g_value_get_as_pointer()). Wed Mar 7 09:32:06 2001 Tim Janik <timj@gtk.org> * glib-object.h: add gvaluearray.h. * gstring.[hc]: fixup naming of g_string_sprint*. * gtypes.h: fixed GCompareDataFunc naming. Wed Mar 7 09:33:27 2001 Tim Janik <timj@gtk.org> * gobject/Makefile.am: shuffled rules to avoid excessive rebuilds. * gobject/gobject-sections.txt: updates. * gobject/tmpl/*: bunch of updates, added another patch from Eric Lemings <eric.b.lemings@lmco.com>.

GTypeValueTable contains the following members: value_init(): initialize a GValue structure. value_free(): free GValue structure contents (optional). value_copy(): copy one GValue contents to another GValue structure of collect_type: varargs collection type for the first variable argument to be collected by collect_value(). collect_value(): variable arguments collection function (optional). lcopy_type: varargs collection type for the first variable argument to be location copyied by lcopy_value(). lcopy_value(): variable arguments location copy function (optional). g_type_value_table_peek(): new function to retrive the GTypeValueTable* for a type node. ValueTables get inherited from parent types, unless overridden through the GTypeInfo structure. internally, GTypeValueTable support means an added overhead of one pointer per static or used dynamic type node. g_type_add_class_cache_func(): provide a cache_func/data pair to be called prior to a type nodes last_unref() function, this can be used to prevent premature class destruction. multiple installed cache_func() will be chained upon last_unref() untill one of them returns TRUE. the cache_func()s have to check the type id passed in to figure whether they actually wants to cache the class of this type (since any types are routed through the cache_func() chain). g_type_remove_class_cache_func(): remove a previously installed cache_func/data pair. the cache maintained by this function has to be clear when calling g_type_remove_class_cache_func() to avoid leaks. g_type_class_unref_uncached(): class unref function for cache_func() implementations, unreferences a class omitting the cache chain (and therefore unref->cache->unref->... loops). * gvaluetypes.[hc]: provide the value setters/getters for the primitive fundamental types boolean, char, uchar, int, uint, long, ulong, float, double and string. * gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a GTypeValueTable is provided for this type. removed g_value_init_default(), g_value_validate(), g_value_defaults(), g_value_set_default() and g_values_cmp() as these are supplied by the GParamSpec API now. moved g_values_exchange() into the "implementation details" section, since it just provides the underlying functionality for g_value_convert(). * gvaluecollector.h: renamed the varargs value container from GParamCValue to GTypeCValue as the value collection methods are supplied by the type system now. G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a GParamSpec structure now. * genums.h: macros cleanups/fixes. * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type and assorted g_value_{s|g}et_{enum|flags}() implementations. * gobject.[hc]: provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods and g_value_{s|g}et_object(). * gparam.[hc]: reduced class to value_set_default(), value_validate() and values_cmp(). also parameters now need to fill in a GType value_type; field to indicate the GValue type they are handling. provide g_param_value_set_default(), g_param_value_defaults(), g_param_value_validate() and g_param_values_cmp(). * gparamspecs.[hc]: got rid of the g_value_* functions and the G_IS_VALUE_* macros. adapted param spec implementations according to the GParamSpecClass changes.

ValueTables get inherited from parent types, unless overridden through the GTypeInfo structure. internally, GTypeValueTable support means an added overhead of one pointer per static or used dynamic type node. g_type_add_class_cache_func(): provide a cache_func/data pair to be called prior to a type nodes last_unref() function, this can be used to prevent premature class destruction. multiple installed cache_func() will be chained upon last_unref() untill one of them returns TRUE. the cache_func()s have to check the type id passed in to figure whether they actually wants to cache the class of this type (since any types are routed through the cache_func() chain). g_type_remove_class_cache_func(): remove a previously installed cache_func/data pair. the cache maintained by this function has to be clear when calling g_type_remove_class_cache_func() to avoid leaks. g_type_class_unref_uncached(): class unref function for cache_func() implementations, unreferences a class omitting the cache chain (and therefore unref->cache->unref->... loops). * gvaluetypes.[hc]: provide the value setters/getters for the primitive fundamental types boolean, char, uchar, int, uint, long, ulong, float, double and string. * gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a GTypeValueTable is provided for this type. removed g_value_init_default(), g_value_validate(), g_value_defaults(), g_value_set_default() and g_values_cmp() as these are supplied by the GParamSpec API now. moved g_values_exchange() into the "implementation details" section, since it just provides the underlying functionality for g_value_convert(). * gvaluecollector.h: renamed the varargs value container from GParamCValue to GTypeCValue as the value collection methods are supplied by the type system now. G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a GParamSpec structure now. * genums.h: macros cleanups/fixes. * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type and assorted g_value_{s|g}et_{enum|flags}() implementations. * gobject.[hc]: provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods and g_value_{s|g}et_object(). * gparam.[hc]: reduced class to value_set_default(), value_validate() and values_cmp(). also parameters now need to fill in a GType value_type; field to indicate the GValue type they are handling. provide g_param_value_set_default(), g_param_value_defaults(), g_param_value_validate() and g_param_values_cmp(). * gparamspecs.[hc]: got rid of the g_value_* functions and the G_IS_VALUE_* macros. adapted param spec implementations according to the GParamSpecClass changes.

(g_signal_connect_object): new function to setup while_alive connections. (g_object_class_install_property): sink properties now, since they are initially floating. (g_object_steal_data): (g_object_set_data_full): (g_object_set_data): (g_object_get_data): set/get data by using g_datalist_*() functions directly. (g_object_queue_param_changed): nuked.

(g_object_thaw_notify): process queue of property changes, therefore emitting GObject::notify::detail with detail being the changed properties names. (G_OBJECT_WARN_INVALID_PROPERTY_ID): saner macro variant of former G_WARN_INVALID_PARAM_ID(). * gparam.[hc]: param specs are now initially floating and need to be sunken with g_param_spec_sink(), support G_TYPE_PARAM values. added G_PARAM_CONSTRUCT and G_PARAM_CONSTRUCT_ONLY parameter flags, required by GObjectClass.constructor(). * gparamspecs.[hc]: added GParamSpecParam, GParamSpecPointer and GParamSpecCCallback, param specs for G_TYPE_PARAM, G_TYPE_POINTER and G_TYPE_CCALLBACK respectively. * gsignal.[hc]: cleanups. (signal_id_lookup): after walking the anchestry, try interfaces as well. (g_signal_new): new function to create signals from varargs type list.

(g_signal_emit_valist): emit signal for an instance with paraneters collected from a va_list. (g_signal_emit): emit signal, taking parameters from varargs list. (g_signal_emit_by_name): same as g_signal_emit, working from signal name+detail. (signal_emit_R): return whether return_value needs to be altered. * gtype.[hc]: set log-domain to GRuntime, i'm slowly getting to all the points that need to reflect the upcoming rename. melt g_type_conforms_to() functionality into g_type_is_a(), as that is what we really want (liskov substitution principle). assorted changes to other files due to conforms_to->is_a. * gvalue.[hc]: implemented g_value_set_instance() that sets a value from an instantiatable type via the value_table's collect_value() function (based on an idea from James Henstridge <james@daa.com.au>). cleanups/fixes. * gvaluetypes.[hc]: implement G_TYPE_CCALLBACK and G_TYPE_PARAM.

GCClosure is also provided in these files, they present a specialized GClosure implementation for C language callbacks. * genum.c: macro cleanups. * gboxed.[hc]: new files, for boxed type abstraction. (g_boxed_copy): copy a boxed structure (g_boxed_free): free a boxed structure (g_value_set_boxed): (g_value_get_boxed): standard GValue functions for boxed types (g_boxed_type_register_static): convenience function for easy introduction of new G_TYPE_BOXED derivatives. * gparam.[hc]: introduced g_param_type_register_static(), a short hand for creation of new GParamSpec derived types. * gtype.[hc]: many fixes, introduced ability to flag individual type nodes as ABSTRACT upon registration, added value_peek_pointer() to the value table to peek at GValue contents as a pointer for types that support this. fixed up GValue checks. * gvalue.[hc]: added g_value_fits_pointer() and g_value_get_as_pointer() to peek at the value contents as pointer. * *.[hc]: adaptions to type macro fixes and changes in the type registration API. * many const corrections over the place. Sat Oct 21 02:49:56 2000 Tim Janik <timj@gtk.org> * gtype.c (g_type_conforms_to): this function basically behaves like and is_a check, except that it _additionally_ features interfaces for instantiatable types. enforce this in the second branch as well (`type' conforms_to `type') even if `type' is not an interface type. Fri Oct 20 15:31:04 2000 Tim Janik <timj@gtk.org> * gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb. * gtype.[hc]: * gobject.c: * gvaluetypes.c: added GTypeValueTable.value_peek_pointer and suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT and G_TYPE_POINTER. Mon Aug 21 04:13:37 2000 Tim Janik <timj@gtk.org> * gbsearcharray.[hc]: long standing needed generic implementation of a binary searchable, sorted and dynamically sized array.

G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a GParamSpec structure now. * genums.h: macros cleanups/fixes. * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type and assorted g_value_{s|g}et_{enum|flags}() implementations. * gobject.[hc]: provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods and g_value_{s|g}et_object(). * gparam.[hc]: reduced class to value_set_default(), value_validate() and values_cmp(). also parameters now need to fill in a GType value_type; field to indicate the GValue type they are handling. provide g_param_value_set_default(), g_param_value_defaults(), g_param_value_validate() and g_param_values_cmp(). * gparamspecs.[hc]: got rid of the g_value_* functions and the G_IS_VALUE_* macros. adapted param spec implementations according to the GParamSpecClass changes.

Tue Oct 24 23:10:26 2000 Tim Janik <timj@gtk.org> * glib-genmarshal.1: * glib-genmarshal.c: added publically installed marshaller generator. * gtype.h: added G_TYPE_INSTANCE_GET_INTERFACE() to retrive a certain interface VTable from instances. Mon Oct 23 08:28:15 2000 Tim Janik <timj@gtk.org> * gobject.[hc]: new functions for closure maintenance: (g_object_watch_closure): maintain validity of the object and the closure for objects that are used as data part of a closure. (g_cclosure_new_object): convenience function to create C closures that have an object as data argument. (g_closure_new_object): convenience function to create closures that have an object as data argument. * gclosure.[hc]: implementation of GClosure mechanism. a closure is basically an encapsulation of a callback function and its environment. ideally, most places supporting callback functions will simply take a GClosure* pointer and thus unify callback environments wrg destroy notification etc. GClosure provides destroy notifiers for arbitrary data pointers, reference counting, invalidation notification (it can be invalidated which is merely a deactivate state) and a marshallinbg abstraction. GCClosure is also provided in these files, they present a specialized GClosure implementation for C language callbacks. * genum.c: macro cleanups. * gboxed.[hc]: new files, for boxed type abstraction. (g_boxed_copy): copy a boxed structure (g_boxed_free): free a boxed structure (g_value_set_boxed): (g_value_get_boxed): standard GValue functions for boxed types (g_boxed_type_register_static): convenience function for easy introduction of new G_TYPE_BOXED derivatives. * gparam.[hc]: introduced g_param_type_register_static(), a short hand for creation of new GParamSpec derived types. * gtype.[hc]: many fixes, introduced ability to flag individual type nodes as ABSTRACT upon registration, added value_peek_pointer() to the value table to peek at GValue contents as a pointer for types that support this. fixed up GValue checks. * gvalue.[hc]: added g_value_fits_pointer() and g_value_get_as_pointer() to peek at the value contents as pointer. * *.[hc]: adaptions to type macro fixes and changes in the type registration API. * many const corrections over the place. Sat Oct 21 02:49:56 2000 Tim Janik <timj@gtk.org> * gtype.c (g_type_conforms_to): this function basically behaves like and is_a check, except that it _additionally_ features interfaces for instantiatable types. enforce this in the second branch as well (`type' conforms_to `type') even if `type' is not an interface type. Fri Oct 20 15:31:04 2000 Tim Janik <timj@gtk.org> * gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb. * gtype.[hc]: * gobject.c: * gvaluetypes.c: added GTypeValueTable.value_peek_pointer and suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT and G_TYPE_POINTER. Mon Aug 21 04:13:37 2000 Tim Janik <timj@gtk.org> * gbsearcharray.[hc]: long standing needed generic implementation of a binary searchable, sorted and dynamically sized array.

define gstring in terms of gchar*. this typedef reflects the type name of Fri Jun 23 17:20:26 2000 Tim Janik <timj@gtk.org> * glib.h: define gstring in terms of gchar*. this typedef reflects the type name of the primitive G_TYPE_STRING in the gobject module. Sat Jun 24 23:03:04 2000 Tim Janik <timj@gtk.org> * gtype.[hc]: provide G_TYPE_CHAR, G_TYPE_UCHAR, G_TYPE_BOOLEAN, G_TYPE_INT, G_TYPE_UINT, G_TYPE_LONG, G_TYPE_ULONG, G_TYPE_FLOAT, G_TYPE_DOUBLE and G_TYPE_STRING fundamental types. added a GTypeValueTable* pointer to GTypeInfo structure for types to implement GValue handling functions. GTypeValueTable contains the following members: value_init(): initialize a GValue structure. value_free(): free GValue structure contents (optional). value_copy(): copy one GValue contents to another GValue structure of collect_type: varargs collection type for the first variable argument to be collected by collect_value(). collect_value(): variable arguments collection function (optional). lcopy_type: varargs collection type for the first variable argument to be location copyied by lcopy_value(). lcopy_value(): variable arguments location copy function (optional). g_type_value_table_peek(): new function to retrive the GTypeValueTable* for a type node. ValueTables get inherited from parent types, unless overridden through the GTypeInfo structure. internally, GTypeValueTable support means an added overhead of one pointer per static or used dynamic type node. g_type_add_class_cache_func(): provide a cache_func/data pair to be called prior to a type nodes last_unref() function, this can be used to prevent premature class destruction. multiple installed cache_func() will be chained upon last_unref() untill one of them returns TRUE. the cache_func()s have to check the type id passed in to figure whether they actually wants to cache the class of this type (since any types are routed through the cache_func() chain). g_type_remove_class_cache_func(): remove a previously installed cache_func/data pair. the cache maintained by this function has to be clear when calling g_type_remove_class_cache_func() to avoid leaks. g_type_class_unref_uncached(): class unref function for cache_func() implementations, unreferences a class omitting the cache chain (and therefore unref->cache->unref->... loops). * gvaluetypes.[hc]: provide the value setters/getters for the primitive fundamental types boolean, char, uchar, int, uint, long, ulong, float, double and string. * gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a GTypeValueTable is provided for this type. removed g_value_init_default(), g_value_validate(), g_value_defaults(), g_value_set_default() and g_values_cmp() as these are supplied by the GParamSpec API now. moved g_values_exchange() into the "implementation details" section, since it just provides the underlying functionality for g_value_convert(). * gvaluecollector.h: renamed the varargs value container from GParamCValue to GTypeCValue as the value collection methods are supplied by the type system now. G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a GParamSpec structure now. * genums.h: macros cleanups/fixes. * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type and assorted g_value_{s|g}et_{enum|flags}() implementations. * gobject.[hc]: provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods and g_value_{s|g}et_object(). * gparam.[hc]: reduced class to value_set_default(), value_validate() and values_cmp(). also parameters now need to fill in a GType value_type; field to indicate the GValue type they are handling. provide g_param_value_set_default(), g_param_value_defaults(), g_param_value_validate() and g_param_values_cmp(). * gparamspecs.[hc]: got rid of the g_value_* functions and the G_IS_VALUE_* macros. adapted param spec implementations according to the GParamSpecClass changes.

Tue Oct 24 23:10:26 2000 Tim Janik <timj@gtk.org> * glib-genmarshal.1: * glib-genmarshal.c: added publically installed marshaller generator. * gtype.h: added G_TYPE_INSTANCE_GET_INTERFACE() to retrive a certain interface VTable from instances. Mon Oct 23 08:28:15 2000 Tim Janik <timj@gtk.org> * gobject.[hc]: new functions for closure maintenance: (g_object_watch_closure): maintain validity of the object and the closure for objects that are used as data part of a closure. (g_cclosure_new_object): convenience function to create C closures that have an object as data argument. (g_closure_new_object): convenience function to create closures that have an object as data argument. * gclosure.[hc]: implementation of GClosure mechanism. a closure is basically an encapsulation of a callback function and its environment. ideally, most places supporting callback functions will simply take a GClosure* pointer and thus unify callback environments wrg destroy notification etc. GClosure provides destroy notifiers for arbitrary data pointers, reference counting, invalidation notification (it can be invalidated which is merely a deactivate state) and a marshallinbg abstraction. GCClosure is also provided in these files, they present a specialized GClosure implementation for C language callbacks. * genum.c: macro cleanups. * gboxed.[hc]: new files, for boxed type abstraction. (g_boxed_copy): copy a boxed structure (g_boxed_free): free a boxed structure (g_value_set_boxed): (g_value_get_boxed): standard GValue functions for boxed types (g_boxed_type_register_static): convenience function for easy introduction of new G_TYPE_BOXED derivatives. * gparam.[hc]: introduced g_param_type_register_static(), a short hand for creation of new GParamSpec derived types. * gtype.[hc]: many fixes, introduced ability to flag individual type nodes as ABSTRACT upon registration, added value_peek_pointer() to the value table to peek at GValue contents as a pointer for types that support this. fixed up GValue checks. * gvalue.[hc]: added g_value_fits_pointer() and g_value_get_as_pointer() to peek at the value contents as pointer. * *.[hc]: adaptions to type macro fixes and changes in the type registration API. * many const corrections over the place. Sat Oct 21 02:49:56 2000 Tim Janik <timj@gtk.org> * gtype.c (g_type_conforms_to): this function basically behaves like and is_a check, except that it _additionally_ features interfaces for instantiatable types. enforce this in the second branch as well (`type' conforms_to `type') even if `type' is not an interface type. Fri Oct 20 15:31:04 2000 Tim Janik <timj@gtk.org> * gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb. * gtype.[hc]: * gobject.c: * gvaluetypes.c: added GTypeValueTable.value_peek_pointer and suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT and G_TYPE_POINTER. Mon Aug 21 04:13:37 2000 Tim Janik <timj@gtk.org> * gbsearcharray.[hc]: long standing needed generic implementation of a binary searchable, sorted and dynamically sized array.

Sat Jun 24 23:03:04 2000 Tim Janik <timj@gtk.org> * gtype.[hc]: provide G_TYPE_CHAR, G_TYPE_UCHAR, G_TYPE_BOOLEAN, G_TYPE_INT, G_TYPE_UINT, G_TYPE_LONG, G_TYPE_ULONG, G_TYPE_FLOAT, G_TYPE_DOUBLE and G_TYPE_STRING fundamental types. added a GTypeValueTable* pointer to GTypeInfo structure for types to implement GValue handling functions. GTypeValueTable contains the following members: value_init(): initialize a GValue structure. value_free(): free GValue structure contents (optional). value_copy(): copy one GValue contents to another GValue structure of collect_type: varargs collection type for the first variable argument to be collected by collect_value(). collect_value(): variable arguments collection function (optional). lcopy_type: varargs collection type for the first variable argument to be location copyied by lcopy_value(). lcopy_value(): variable arguments location copy function (optional). g_type_value_table_peek(): new function to retrive the GTypeValueTable* for a type node. ValueTables get inherited from parent types, unless overridden through the GTypeInfo structure. internally, GTypeValueTable support means an added overhead of one pointer per static or used dynamic type node. g_type_add_class_cache_func(): provide a cache_func/data pair to be called prior to a type nodes last_unref() function, this can be used to prevent premature class destruction. multiple installed cache_func() will be chained upon last_unref() untill one of them returns TRUE. the cache_func()s have to check the type id passed in to figure whether they actually wants to cache the class of this type (since any types are routed through the cache_func() chain). g_type_remove_class_cache_func(): remove a previously installed cache_func/data pair. the cache maintained by this function has to be clear when calling g_type_remove_class_cache_func() to avoid leaks. g_type_class_unref_uncached(): class unref function for cache_func() implementations, unreferences a class omitting the cache chain (and therefore unref->cache->unref->... loops). * gvaluetypes.[hc]: provide the value setters/getters for the primitive fundamental types boolean, char, uchar, int, uint, long, ulong, float, double and string. * gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a GTypeValueTable is provided for this type. removed g_value_init_default(), g_value_validate(), g_value_defaults(), g_value_set_default() and g_values_cmp() as these are supplied by the GParamSpec API now. moved g_values_exchange() into the "implementation details" section, since it just provides the underlying functionality for g_value_convert(). * gvaluecollector.h: renamed the varargs value container from GParamCValue to GTypeCValue as the value collection methods are supplied by the type system now. G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a GParamSpec structure now. * genums.h: macros cleanups/fixes. * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type and assorted g_value_{s|g}et_{enum|flags}() implementations. * gobject.[hc]: provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods and g_value_{s|g}et_object(). * gparam.[hc]: reduced class to value_set_default(), value_validate() and values_cmp(). also parameters now need to fill in a GType value_type; field to indicate the GValue type they are handling. provide g_param_value_set_default(), g_param_value_defaults(), g_param_value_validate() and g_param_values_cmp(). * gparamspecs.[hc]: got rid of the g_value_* functions and the G_IS_VALUE_* macros. adapted param spec implementations according to the GParamSpecClass changes.

(g_closure_new_object): convenience function to create closures that have an object as data argument. * gclosure.[hc]: implementation of GClosure mechanism. a closure is basically an encapsulation of a callback function and its environment. ideally, most places supporting callback functions will simply take a GClosure* pointer and thus unify callback environments wrg destroy notification etc. GClosure provides destroy notifiers for arbitrary data pointers, reference counting, invalidation notification (it can be invalidated which is merely a deactivate state) and a marshallinbg abstraction. GCClosure is also provided in these files, they present a specialized GClosure implementation for C language callbacks. * genum.c: macro cleanups. * gboxed.[hc]: new files, for boxed type abstraction. (g_boxed_copy): copy a boxed structure (g_boxed_free): free a boxed structure (g_value_set_boxed): (g_value_get_boxed): standard GValue functions for boxed types (g_boxed_type_register_static): convenience function for easy introduction of new G_TYPE_BOXED derivatives. * gparam.[hc]: introduced g_param_type_register_static(), a short hand for creation of new GParamSpec derived types. * gtype.[hc]: many fixes, introduced ability to flag individual type nodes as ABSTRACT upon registration, added value_peek_pointer() to the value table to peek at GValue contents as a pointer for types that support this. fixed up GValue checks. * gvalue.[hc]: added g_value_fits_pointer() and g_value_get_as_pointer() to peek at the value contents as pointer. * *.[hc]: adaptions to type macro fixes and changes in the type registration API. * many const corrections over the place. Sat Oct 21 02:49:56 2000 Tim Janik <timj@gtk.org> * gtype.c (g_type_conforms_to): this function basically behaves like and is_a check, except that it _additionally_ features interfaces for instantiatable types. enforce this in the second branch as well (`type' conforms_to `type') even if `type' is not an interface type. Fri Oct 20 15:31:04 2000 Tim Janik <timj@gtk.org> * gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb. * gtype.[hc]: * gobject.c: * gvaluetypes.c: added GTypeValueTable.value_peek_pointer and suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT and G_TYPE_POINTER. Mon Aug 21 04:13:37 2000 Tim Janik <timj@gtk.org> * gbsearcharray.[hc]: long standing needed generic implementation of a binary searchable, sorted and dynamically sized array.

ValueTables get inherited from parent types, unless overridden through the GTypeInfo structure. internally, GTypeValueTable support means an added overhead of one pointer per static or used dynamic type node. g_type_add_class_cache_func(): provide a cache_func/data pair to be called prior to a type nodes last_unref() function, this can be used to prevent premature class destruction. multiple installed cache_func() will be chained upon last_unref() untill one of them returns TRUE. the cache_func()s have to check the type id passed in to figure whether they actually wants to cache the class of this type (since any types are routed through the cache_func() chain). g_type_remove_class_cache_func(): remove a previously installed cache_func/data pair. the cache maintained by this function has to be clear when calling g_type_remove_class_cache_func() to avoid leaks. g_type_class_unref_uncached(): class unref function for cache_func() implementations, unreferences a class omitting the cache chain (and therefore unref->cache->unref->... loops). * gvaluetypes.[hc]: provide the value setters/getters for the primitive fundamental types boolean, char, uchar, int, uint, long, ulong, float, double and string. * gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a GTypeValueTable is provided for this type. removed g_value_init_default(), g_value_validate(), g_value_defaults(), g_value_set_default() and g_values_cmp() as these are supplied by the GParamSpec API now. moved g_values_exchange() into the "implementation details" section, since it just provides the underlying functionality for g_value_convert(). * gvaluecollector.h: renamed the varargs value container from GParamCValue to GTypeCValue as the value collection methods are supplied by the type system now. G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a GParamSpec structure now. * genums.h: macros cleanups/fixes. * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type and assorted g_value_{s|g}et_{enum|flags}() implementations. * gobject.[hc]: provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods and g_value_{s|g}et_object(). * gparam.[hc]: reduced class to value_set_default(), value_validate() and values_cmp(). also parameters now need to fill in a GType value_type; field to indicate the GValue type they are handling. provide g_param_value_set_default(), g_param_value_defaults(), g_param_value_validate() and g_param_values_cmp(). * gparamspecs.[hc]: got rid of the g_value_* functions and the G_IS_VALUE_* macros. adapted param spec implementations according to the GParamSpecClass changes.

(g_boxed_copy): copy a boxed structure (g_boxed_free): free a boxed structure (g_value_set_boxed): (g_value_get_boxed): standard GValue functions for boxed types (g_boxed_type_register_static): convenience function for easy introduction of new G_TYPE_BOXED derivatives. * gparam.[hc]: introduced g_param_type_register_static(), a short hand for creation of new GParamSpec derived types. * gtype.[hc]: many fixes, introduced ability to flag individual type nodes as ABSTRACT upon registration, added value_peek_pointer() to the value table to peek at GValue contents as a pointer for types that support this. fixed up GValue checks. * gvalue.[hc]: added g_value_fits_pointer() and g_value_get_as_pointer() to peek at the value contents as pointer. * *.[hc]: adaptions to type macro fixes and changes in the type registration API. * many const corrections over the place. Sat Oct 21 02:49:56 2000 Tim Janik <timj@gtk.org> * gtype.c (g_type_conforms_to): this function basically behaves like and is_a check, except that it _additionally_ features interfaces for instantiatable types. enforce this in the second branch as well (`type' conforms_to `type') even if `type' is not an interface type. Fri Oct 20 15:31:04 2000 Tim Janik <timj@gtk.org> * gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb. * gtype.[hc]: * gobject.c: * gvaluetypes.c: added GTypeValueTable.value_peek_pointer and suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT and G_TYPE_POINTER. Mon Aug 21 04:13:37 2000 Tim Janik <timj@gtk.org> * gbsearcharray.[hc]: long standing needed generic implementation of a binary searchable, sorted and dynamically sized array.

gchar
added newly added gobject/ headers. Tue Oct 24 22:09:14 2000 Tim Janik <timj@gtk.org> * glib-object.h: added newly added gobject/ headers. * gmesage.c: print g_message() output to stderr instead of stdout. Wed Oct 25 20:27:02 2000 Tim Janik <timj@gtk.org> * gtype.c (g_type_free_instance): for the moment, freeing object structures will fill their memory portion with 0xAA. there's a FIXME there, remove this line at a later point. Tue Oct 24 23:10:26 2000 Tim Janik <timj@gtk.org> * glib-genmarshal.1: * glib-genmarshal.c: added publically installed marshaller generator. * gtype.h: added G_TYPE_INSTANCE_GET_INTERFACE() to retrive a certain interface VTable from instances. Mon Oct 23 08:28:15 2000 Tim Janik <timj@gtk.org> * gobject.[hc]: new functions for closure maintenance: (g_object_watch_closure): maintain validity of the object and the closure for objects that are used as data part of a closure. (g_cclosure_new_object): convenience function to create C closures that have an object as data argument. (g_closure_new_object): convenience function to create closures that have an object as data argument. * gclosure.[hc]: implementation of GClosure mechanism. a closure is basically an encapsulation of a callback function and its environment. ideally, most places supporting callback functions will simply take a GClosure* pointer and thus unify callback environments wrg destroy notification etc. GClosure provides destroy notifiers for arbitrary data pointers, reference counting, invalidation notification (it can be invalidated which is merely a deactivate state) and a marshallinbg abstraction. GCClosure is also provided in these files, they present a specialized GClosure implementation for C language callbacks. * genum.c: macro cleanups. * gboxed.[hc]: new files, for boxed type abstraction. (g_boxed_copy): copy a boxed structure (g_boxed_free): free a boxed structure (g_value_set_boxed): (g_value_get_boxed): standard GValue functions for boxed types (g_boxed_type_register_static): convenience function for easy introduction of new G_TYPE_BOXED derivatives. * gparam.[hc]: introduced g_param_type_register_static(), a short hand for creation of new GParamSpec derived types. * gtype.[hc]: many fixes, introduced ability to flag individual type nodes as ABSTRACT upon registration, added value_peek_pointer() to the value table to peek at GValue contents as a pointer for types that support this. fixed up GValue checks. * gvalue.[hc]: added g_value_fits_pointer() and g_value_get_as_pointer() to peek at the value contents as pointer. * *.[hc]: adaptions to type macro fixes and changes in the type registration API. * many const corrections over the place. Sat Oct 21 02:49:56 2000 Tim Janik <timj@gtk.org> * gtype.c (g_type_conforms_to): this function basically behaves like and is_a check, except that it _additionally_ features interfaces for instantiatable types. enforce this in the second branch as well (`type' conforms_to `type') even if `type' is not an interface type. Fri Oct 20 15:31:04 2000 Tim Janik <timj@gtk.org> * gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb. * gtype.[hc]: * gobject.c: * gvaluetypes.c: added GTypeValueTable.value_peek_pointer and suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT and G_TYPE_POINTER. Mon Aug 21 04:13:37 2000 Tim Janik <timj@gtk.org> * gbsearcharray.[hc]: long standing needed generic implementation of a binary searchable, sorted and dynamically sized array.

Sat Jun 24 23:03:04 2000 Tim Janik <timj@gtk.org> * gtype.[hc]: provide G_TYPE_CHAR, G_TYPE_UCHAR, G_TYPE_BOOLEAN, G_TYPE_INT, G_TYPE_UINT, G_TYPE_LONG, G_TYPE_ULONG, G_TYPE_FLOAT, G_TYPE_DOUBLE and G_TYPE_STRING fundamental types. added a GTypeValueTable* pointer to GTypeInfo structure for types to implement GValue handling functions. GTypeValueTable contains the following members: value_init(): initialize a GValue structure. value_free(): free GValue structure contents (optional). value_copy(): copy one GValue contents to another GValue structure of collect_type: varargs collection type for the first variable argument to be collected by collect_value(). collect_value(): variable arguments collection function (optional). lcopy_type: varargs collection type for the first variable argument to be location copyied by lcopy_value(). lcopy_value(): variable arguments location copy function (optional). g_type_value_table_peek(): new function to retrive the GTypeValueTable* for a type node. ValueTables get inherited from parent types, unless overridden through the GTypeInfo structure. internally, GTypeValueTable support means an added overhead of one pointer per static or used dynamic type node. g_type_add_class_cache_func(): provide a cache_func/data pair to be called prior to a type nodes last_unref() function, this can be used to prevent premature class destruction. multiple installed cache_func() will be chained upon last_unref() untill one of them returns TRUE. the cache_func()s have to check the type id passed in to figure whether they actually wants to cache the class of this type (since any types are routed through the cache_func() chain). g_type_remove_class_cache_func(): remove a previously installed cache_func/data pair. the cache maintained by this function has to be clear when calling g_type_remove_class_cache_func() to avoid leaks. g_type_class_unref_uncached(): class unref function for cache_func() implementations, unreferences a class omitting the cache chain (and therefore unref->cache->unref->... loops). * gvaluetypes.[hc]: provide the value setters/getters for the primitive fundamental types boolean, char, uchar, int, uint, long, ulong, float, double and string. * gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a GTypeValueTable is provided for this type. removed g_value_init_default(), g_value_validate(), g_value_defaults(), g_value_set_default() and g_values_cmp() as these are supplied by the GParamSpec API now. moved g_values_exchange() into the "implementation details" section, since it just provides the underlying functionality for g_value_convert(). * gvaluecollector.h: renamed the varargs value container from GParamCValue to GTypeCValue as the value collection methods are supplied by the type system now. G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a GParamSpec structure now. * genums.h: macros cleanups/fixes. * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type and assorted g_value_{s|g}et_{enum|flags}() implementations. * gobject.[hc]: provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods and g_value_{s|g}et_object(). * gparam.[hc]: reduced class to value_set_default(), value_validate() and values_cmp(). also parameters now need to fill in a GType value_type; field to indicate the GValue type they are handling. provide g_param_value_set_default(), g_param_value_defaults(), g_param_value_validate() and g_param_values_cmp(). * gparamspecs.[hc]: got rid of the g_value_* functions and the G_IS_VALUE_* macros. adapted param spec implementations according to the GParamSpecClass changes.

GTypeValueTable contains the following members: value_init(): initialize a GValue structure. value_free(): free GValue structure contents (optional). value_copy(): copy one GValue contents to another GValue structure of collect_type: varargs collection type for the first variable argument to be collected by collect_value(). collect_value(): variable arguments collection function (optional). lcopy_type: varargs collection type for the first variable argument to be location copyied by lcopy_value(). lcopy_value(): variable arguments location copy function (optional). g_type_value_table_peek(): new function to retrive the GTypeValueTable* for a type node. ValueTables get inherited from parent types, unless overridden through the GTypeInfo structure. internally, GTypeValueTable support means an added overhead of one pointer per static or used dynamic type node. g_type_add_class_cache_func(): provide a cache_func/data pair to be called prior to a type nodes last_unref() function, this can be used to prevent premature class destruction. multiple installed cache_func() will be chained upon last_unref() untill one of them returns TRUE. the cache_func()s have to check the type id passed in to figure whether they actually wants to cache the class of this type (since any types are routed through the cache_func() chain). g_type_remove_class_cache_func(): remove a previously installed cache_func/data pair. the cache maintained by this function has to be clear when calling g_type_remove_class_cache_func() to avoid leaks. g_type_class_unref_uncached(): class unref function for cache_func() implementations, unreferences a class omitting the cache chain (and therefore unref->cache->unref->... loops). * gvaluetypes.[hc]: provide the value setters/getters for the primitive fundamental types boolean, char, uchar, int, uint, long, ulong, float, double and string. * gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a GTypeValueTable is provided for this type. removed g_value_init_default(), g_value_validate(), g_value_defaults(), g_value_set_default() and g_values_cmp() as these are supplied by the GParamSpec API now. moved g_values_exchange() into the "implementation details" section, since it just provides the underlying functionality for g_value_convert(). * gvaluecollector.h: renamed the varargs value container from GParamCValue to GTypeCValue as the value collection methods are supplied by the type system now. G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a GParamSpec structure now. * genums.h: macros cleanups/fixes. * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type and assorted g_value_{s|g}et_{enum|flags}() implementations. * gobject.[hc]: provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods and g_value_{s|g}et_object(). * gparam.[hc]: reduced class to value_set_default(), value_validate() and values_cmp(). also parameters now need to fill in a GType value_type; field to indicate the GValue type they are handling. provide g_param_value_set_default(), g_param_value_defaults(), g_param_value_validate() and g_param_values_cmp(). * gparamspecs.[hc]: got rid of the g_value_* functions and the G_IS_VALUE_* macros. adapted param spec implementations according to the GParamSpecClass changes.

(g_boxed_copy): copy a boxed structure (g_boxed_free): free a boxed structure (g_value_set_boxed): (g_value_get_boxed): standard GValue functions for boxed types (g_boxed_type_register_static): convenience function for easy introduction of new G_TYPE_BOXED derivatives. * gparam.[hc]: introduced g_param_type_register_static(), a short hand for creation of new GParamSpec derived types. * gtype.[hc]: many fixes, introduced ability to flag individual type nodes as ABSTRACT upon registration, added value_peek_pointer() to the value table to peek at GValue contents as a pointer for types that support this. fixed up GValue checks. * gvalue.[hc]: added g_value_fits_pointer() and g_value_get_as_pointer() to peek at the value contents as pointer. * *.[hc]: adaptions to type macro fixes and changes in the type registration API. * many const corrections over the place. Sat Oct 21 02:49:56 2000 Tim Janik <timj@gtk.org> * gtype.c (g_type_conforms_to): this function basically behaves like and is_a check, except that it _additionally_ features interfaces for instantiatable types. enforce this in the second branch as well (`type' conforms_to `type') even if `type' is not an interface type. Fri Oct 20 15:31:04 2000 Tim Janik <timj@gtk.org> * gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb. * gtype.[hc]: * gobject.c: * gvaluetypes.c: added GTypeValueTable.value_peek_pointer and suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT and G_TYPE_POINTER. Mon Aug 21 04:13:37 2000 Tim Janik <timj@gtk.org> * gbsearcharray.[hc]: long standing needed generic implementation of a binary searchable, sorted and dynamically sized array.

ValueTables get inherited from parent types, unless overridden through the GTypeInfo structure. internally, GTypeValueTable support means an added overhead of one pointer per static or used dynamic type node. g_type_add_class_cache_func(): provide a cache_func/data pair to be called prior to a type nodes last_unref() function, this can be used to prevent premature class destruction. multiple installed cache_func() will be chained upon last_unref() untill one of them returns TRUE. the cache_func()s have to check the type id passed in to figure whether they actually wants to cache the class of this type (since any types are routed through the cache_func() chain). g_type_remove_class_cache_func(): remove a previously installed cache_func/data pair. the cache maintained by this function has to be clear when calling g_type_remove_class_cache_func() to avoid leaks. g_type_class_unref_uncached(): class unref function for cache_func() implementations, unreferences a class omitting the cache chain (and therefore unref->cache->unref->... loops). * gvaluetypes.[hc]: provide the value setters/getters for the primitive fundamental types boolean, char, uchar, int, uint, long, ulong, float, double and string. * gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a GTypeValueTable is provided for this type. removed g_value_init_default(), g_value_validate(), g_value_defaults(), g_value_set_default() and g_values_cmp() as these are supplied by the GParamSpec API now. moved g_values_exchange() into the "implementation details" section, since it just provides the underlying functionality for g_value_convert(). * gvaluecollector.h: renamed the varargs value container from GParamCValue to GTypeCValue as the value collection methods are supplied by the type system now. G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a GParamSpec structure now. * genums.h: macros cleanups/fixes. * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type and assorted g_value_{s|g}et_{enum|flags}() implementations. * gobject.[hc]: provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods and g_value_{s|g}et_object(). * gparam.[hc]: reduced class to value_set_default(), value_validate() and values_cmp(). also parameters now need to fill in a GType value_type; field to indicate the GValue type they are handling. provide g_param_value_set_default(), g_param_value_defaults(), g_param_value_validate() and g_param_values_cmp(). * gparamspecs.[hc]: got rid of the g_value_* functions and the G_IS_VALUE_* macros. adapted param spec implementations according to the GParamSpecClass changes.

Wed Oct 25 20:27:02 2000 Tim Janik <timj@gtk.org> * gtype.c (g_type_free_instance): for the moment, freeing object structures will fill their memory portion with 0xAA. there's a FIXME there, remove this line at a later point. Tue Oct 24 23:10:26 2000 Tim Janik <timj@gtk.org> * glib-genmarshal.1: * glib-genmarshal.c: added publically installed marshaller generator. * gtype.h: added G_TYPE_INSTANCE_GET_INTERFACE() to retrive a certain interface VTable from instances. Mon Oct 23 08:28:15 2000 Tim Janik <timj@gtk.org> * gobject.[hc]: new functions for closure maintenance: (g_object_watch_closure): maintain validity of the object and the closure for objects that are used as data part of a closure. (g_cclosure_new_object): convenience function to create C closures that have an object as data argument. (g_closure_new_object): convenience function to create closures that have an object as data argument. * gclosure.[hc]: implementation of GClosure mechanism. a closure is basically an encapsulation of a callback function and its environment. ideally, most places supporting callback functions will simply take a GClosure* pointer and thus unify callback environments wrg destroy notification etc. GClosure provides destroy notifiers for arbitrary data pointers, reference counting, invalidation notification (it can be invalidated which is merely a deactivate state) and a marshallinbg abstraction. GCClosure is also provided in these files, they present a specialized GClosure implementation for C language callbacks. * genum.c: macro cleanups. * gboxed.[hc]: new files, for boxed type abstraction. (g_boxed_copy): copy a boxed structure (g_boxed_free): free a boxed structure (g_value_set_boxed): (g_value_get_boxed): standard GValue functions for boxed types (g_boxed_type_register_static): convenience function for easy introduction of new G_TYPE_BOXED derivatives. * gparam.[hc]: introduced g_param_type_register_static(), a short hand for creation of new GParamSpec derived types. * gtype.[hc]: many fixes, introduced ability to flag individual type nodes as ABSTRACT upon registration, added value_peek_pointer() to the value table to peek at GValue contents as a pointer for types that support this. fixed up GValue checks. * gvalue.[hc]: added g_value_fits_pointer() and g_value_get_as_pointer() to peek at the value contents as pointer. * *.[hc]: adaptions to type macro fixes and changes in the type registration API. * many const corrections over the place. Sat Oct 21 02:49:56 2000 Tim Janik <timj@gtk.org> * gtype.c (g_type_conforms_to): this function basically behaves like and is_a check, except that it _additionally_ features interfaces for instantiatable types. enforce this in the second branch as well (`type' conforms_to `type') even if `type' is not an interface type. Fri Oct 20 15:31:04 2000 Tim Janik <timj@gtk.org> * gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb. * gtype.[hc]: * gobject.c: * gvaluetypes.c: added GTypeValueTable.value_peek_pointer and suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT and G_TYPE_POINTER. Mon Aug 21 04:13:37 2000 Tim Janik <timj@gtk.org> * gbsearcharray.[hc]: long standing needed generic implementation of a binary searchable, sorted and dynamically sized array.

Wed Oct 25 20:27:02 2000 Tim Janik <timj@gtk.org> * gtype.c (g_type_free_instance): for the moment, freeing object structures will fill their memory portion with 0xAA. there's a FIXME there, remove this line at a later point. Tue Oct 24 23:10:26 2000 Tim Janik <timj@gtk.org> * glib-genmarshal.1: * glib-genmarshal.c: added publically installed marshaller generator. * gtype.h: added G_TYPE_INSTANCE_GET_INTERFACE() to retrive a certain interface VTable from instances. Mon Oct 23 08:28:15 2000 Tim Janik <timj@gtk.org> * gobject.[hc]: new functions for closure maintenance: (g_object_watch_closure): maintain validity of the object and the closure for objects that are used as data part of a closure. (g_cclosure_new_object): convenience function to create C closures that have an object as data argument. (g_closure_new_object): convenience function to create closures that have an object as data argument. * gclosure.[hc]: implementation of GClosure mechanism. a closure is basically an encapsulation of a callback function and its environment. ideally, most places supporting callback functions will simply take a GClosure* pointer and thus unify callback environments wrg destroy notification etc. GClosure provides destroy notifiers for arbitrary data pointers, reference counting, invalidation notification (it can be invalidated which is merely a deactivate state) and a marshallinbg abstraction. GCClosure is also provided in these files, they present a specialized GClosure implementation for C language callbacks. * genum.c: macro cleanups. * gboxed.[hc]: new files, for boxed type abstraction. (g_boxed_copy): copy a boxed structure (g_boxed_free): free a boxed structure (g_value_set_boxed): (g_value_get_boxed): standard GValue functions for boxed types (g_boxed_type_register_static): convenience function for easy introduction of new G_TYPE_BOXED derivatives. * gparam.[hc]: introduced g_param_type_register_static(), a short hand for creation of new GParamSpec derived types. * gtype.[hc]: many fixes, introduced ability to flag individual type nodes as ABSTRACT upon registration, added value_peek_pointer() to the value table to peek at GValue contents as a pointer for types that support this. fixed up GValue checks. * gvalue.[hc]: added g_value_fits_pointer() and g_value_get_as_pointer() to peek at the value contents as pointer. * *.[hc]: adaptions to type macro fixes and changes in the type registration API. * many const corrections over the place. Sat Oct 21 02:49:56 2000 Tim Janik <timj@gtk.org> * gtype.c (g_type_conforms_to): this function basically behaves like and is_a check, except that it _additionally_ features interfaces for instantiatable types. enforce this in the second branch as well (`type' conforms_to `type') even if `type' is not an interface type. Fri Oct 20 15:31:04 2000 Tim Janik <timj@gtk.org> * gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb. * gtype.[hc]: * gobject.c: * gvaluetypes.c: added GTypeValueTable.value_peek_pointer and suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT and G_TYPE_POINTER. Mon Aug 21 04:13:37 2000 Tim Janik <timj@gtk.org> * gbsearcharray.[hc]: long standing needed generic implementation of a binary searchable, sorted and dynamically sized array.

Wed Oct 25 20:27:02 2000 Tim Janik <timj@gtk.org> * gtype.c (g_type_free_instance): for the moment, freeing object structures will fill their memory portion with 0xAA. there's a FIXME there, remove this line at a later point. Tue Oct 24 23:10:26 2000 Tim Janik <timj@gtk.org> * glib-genmarshal.1: * glib-genmarshal.c: added publically installed marshaller generator. * gtype.h: added G_TYPE_INSTANCE_GET_INTERFACE() to retrive a certain interface VTable from instances. Mon Oct 23 08:28:15 2000 Tim Janik <timj@gtk.org> * gobject.[hc]: new functions for closure maintenance: (g_object_watch_closure): maintain validity of the object and the closure for objects that are used as data part of a closure. (g_cclosure_new_object): convenience function to create C closures that have an object as data argument. (g_closure_new_object): convenience function to create closures that have an object as data argument. * gclosure.[hc]: implementation of GClosure mechanism. a closure is basically an encapsulation of a callback function and its environment. ideally, most places supporting callback functions will simply take a GClosure* pointer and thus unify callback environments wrg destroy notification etc. GClosure provides destroy notifiers for arbitrary data pointers, reference counting, invalidation notification (it can be invalidated which is merely a deactivate state) and a marshallinbg abstraction. GCClosure is also provided in these files, they present a specialized GClosure implementation for C language callbacks. * genum.c: macro cleanups. * gboxed.[hc]: new files, for boxed type abstraction. (g_boxed_copy): copy a boxed structure (g_boxed_free): free a boxed structure (g_value_set_boxed): (g_value_get_boxed): standard GValue functions for boxed types (g_boxed_type_register_static): convenience function for easy introduction of new G_TYPE_BOXED derivatives. * gparam.[hc]: introduced g_param_type_register_static(), a short hand for creation of new GParamSpec derived types. * gtype.[hc]: many fixes, introduced ability to flag individual type nodes as ABSTRACT upon registration, added value_peek_pointer() to the value table to peek at GValue contents as a pointer for types that support this. fixed up GValue checks. * gvalue.[hc]: added g_value_fits_pointer() and g_value_get_as_pointer() to peek at the value contents as pointer. * *.[hc]: adaptions to type macro fixes and changes in the type registration API. * many const corrections over the place. Sat Oct 21 02:49:56 2000 Tim Janik <timj@gtk.org> * gtype.c (g_type_conforms_to): this function basically behaves like and is_a check, except that it _additionally_ features interfaces for instantiatable types. enforce this in the second branch as well (`type' conforms_to `type') even if `type' is not an interface type. Fri Oct 20 15:31:04 2000 Tim Janik <timj@gtk.org> * gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb. * gtype.[hc]: * gobject.c: * gvaluetypes.c: added GTypeValueTable.value_peek_pointer and suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT and G_TYPE_POINTER. Mon Aug 21 04:13:37 2000 Tim Janik <timj@gtk.org> * gbsearcharray.[hc]: long standing needed generic implementation of a binary searchable, sorted and dynamically sized array.

ValueTables get inherited from parent types, unless overridden through the GTypeInfo structure. internally, GTypeValueTable support means an added overhead of one pointer per static or used dynamic type node. g_type_add_class_cache_func(): provide a cache_func/data pair to be called prior to a type nodes last_unref() function, this can be used to prevent premature class destruction. multiple installed cache_func() will be chained upon last_unref() untill one of them returns TRUE. the cache_func()s have to check the type id passed in to figure whether they actually wants to cache the class of this type (since any types are routed through the cache_func() chain). g_type_remove_class_cache_func(): remove a previously installed cache_func/data pair. the cache maintained by this function has to be clear when calling g_type_remove_class_cache_func() to avoid leaks. g_type_class_unref_uncached(): class unref function for cache_func() implementations, unreferences a class omitting the cache chain (and therefore unref->cache->unref->... loops). * gvaluetypes.[hc]: provide the value setters/getters for the primitive fundamental types boolean, char, uchar, int, uint, long, ulong, float, double and string. * gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a GTypeValueTable is provided for this type. removed g_value_init_default(), g_value_validate(), g_value_defaults(), g_value_set_default() and g_values_cmp() as these are supplied by the GParamSpec API now. moved g_values_exchange() into the "implementation details" section, since it just provides the underlying functionality for g_value_convert(). * gvaluecollector.h: renamed the varargs value container from GParamCValue to GTypeCValue as the value collection methods are supplied by the type system now. G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a GParamSpec structure now. * genums.h: macros cleanups/fixes. * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type and assorted g_value_{s|g}et_{enum|flags}() implementations. * gobject.[hc]: provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods and g_value_{s|g}et_object(). * gparam.[hc]: reduced class to value_set_default(), value_validate() and values_cmp(). also parameters now need to fill in a GType value_type; field to indicate the GValue type they are handling. provide g_param_value_set_default(), g_param_value_defaults(), g_param_value_validate() and g_param_values_cmp(). * gparamspecs.[hc]: got rid of the g_value_* functions and the G_IS_VALUE_* macros. adapted param spec implementations according to the GParamSpecClass changes.

Wed Oct 25 20:27:02 2000 Tim Janik <timj@gtk.org> * gtype.c (g_type_free_instance): for the moment, freeing object structures will fill their memory portion with 0xAA. there's a FIXME there, remove this line at a later point. Tue Oct 24 23:10:26 2000 Tim Janik <timj@gtk.org> * glib-genmarshal.1: * glib-genmarshal.c: added publically installed marshaller generator. * gtype.h: added G_TYPE_INSTANCE_GET_INTERFACE() to retrive a certain interface VTable from instances. Mon Oct 23 08:28:15 2000 Tim Janik <timj@gtk.org> * gobject.[hc]: new functions for closure maintenance: (g_object_watch_closure): maintain validity of the object and the closure for objects that are used as data part of a closure. (g_cclosure_new_object): convenience function to create C closures that have an object as data argument. (g_closure_new_object): convenience function to create closures that have an object as data argument. * gclosure.[hc]: implementation of GClosure mechanism. a closure is basically an encapsulation of a callback function and its environment. ideally, most places supporting callback functions will simply take a GClosure* pointer and thus unify callback environments wrg destroy notification etc. GClosure provides destroy notifiers for arbitrary data pointers, reference counting, invalidation notification (it can be invalidated which is merely a deactivate state) and a marshallinbg abstraction. GCClosure is also provided in these files, they present a specialized GClosure implementation for C language callbacks. * genum.c: macro cleanups. * gboxed.[hc]: new files, for boxed type abstraction. (g_boxed_copy): copy a boxed structure (g_boxed_free): free a boxed structure (g_value_set_boxed): (g_value_get_boxed): standard GValue functions for boxed types (g_boxed_type_register_static): convenience function for easy introduction of new G_TYPE_BOXED derivatives. * gparam.[hc]: introduced g_param_type_register_static(), a short hand for creation of new GParamSpec derived types. * gtype.[hc]: many fixes, introduced ability to flag individual type nodes as ABSTRACT upon registration, added value_peek_pointer() to the value table to peek at GValue contents as a pointer for types that support this. fixed up GValue checks. * gvalue.[hc]: added g_value_fits_pointer() and g_value_get_as_pointer() to peek at the value contents as pointer. * *.[hc]: adaptions to type macro fixes and changes in the type registration API. * many const corrections over the place. Sat Oct 21 02:49:56 2000 Tim Janik <timj@gtk.org> * gtype.c (g_type_conforms_to): this function basically behaves like and is_a check, except that it _additionally_ features interfaces for instantiatable types. enforce this in the second branch as well (`type' conforms_to `type') even if `type' is not an interface type. Fri Oct 20 15:31:04 2000 Tim Janik <timj@gtk.org> * gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb. * gtype.[hc]: * gobject.c: * gvaluetypes.c: added GTypeValueTable.value_peek_pointer and suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT and G_TYPE_POINTER. Mon Aug 21 04:13:37 2000 Tim Janik <timj@gtk.org> * gbsearcharray.[hc]: long standing needed generic implementation of a binary searchable, sorted and dynamically sized array.

ValueTables get inherited from parent types, unless overridden through the GTypeInfo structure. internally, GTypeValueTable support means an added overhead of one pointer per static or used dynamic type node. g_type_add_class_cache_func(): provide a cache_func/data pair to be called prior to a type nodes last_unref() function, this can be used to prevent premature class destruction. multiple installed cache_func() will be chained upon last_unref() untill one of them returns TRUE. the cache_func()s have to check the type id passed in to figure whether they actually wants to cache the class of this type (since any types are routed through the cache_func() chain). g_type_remove_class_cache_func(): remove a previously installed cache_func/data pair. the cache maintained by this function has to be clear when calling g_type_remove_class_cache_func() to avoid leaks. g_type_class_unref_uncached(): class unref function for cache_func() implementations, unreferences a class omitting the cache chain (and therefore unref->cache->unref->... loops). * gvaluetypes.[hc]: provide the value setters/getters for the primitive fundamental types boolean, char, uchar, int, uint, long, ulong, float, double and string. * gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a GTypeValueTable is provided for this type. removed g_value_init_default(), g_value_validate(), g_value_defaults(), g_value_set_default() and g_values_cmp() as these are supplied by the GParamSpec API now. moved g_values_exchange() into the "implementation details" section, since it just provides the underlying functionality for g_value_convert(). * gvaluecollector.h: renamed the varargs value container from GParamCValue to GTypeCValue as the value collection methods are supplied by the type system now. G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a GParamSpec structure now. * genums.h: macros cleanups/fixes. * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type and assorted g_value_{s|g}et_{enum|flags}() implementations. * gobject.[hc]: provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods and g_value_{s|g}et_object(). * gparam.[hc]: reduced class to value_set_default(), value_validate() and values_cmp(). also parameters now need to fill in a GType value_type; field to indicate the GValue type they are handling. provide g_param_value_set_default(), g_param_value_defaults(), g_param_value_validate() and g_param_values_cmp(). * gparamspecs.[hc]: got rid of the g_value_* functions and the G_IS_VALUE_* macros. adapted param spec implementations according to the GParamSpecClass changes.

Tue Feb 27 18:35:15 2001 Tim Janik <timj@gtk.org> * gobject.c (g_object_get_valist): urg, pass G_VALUE_NOCOPY_CONTENTS into G_VALUE_LCOPY(), this needs proper documenting. * gparam.c: fixed G_PARAM_USER_MASK. * gtype.c (type_data_make_W): (type_data_last_unref_Wm): fixed invalid memory freeing. * gobject.c (g_object_last_unref): destroy signal handlers associated with object, right before finalization. * gsignal.c (g_signal_parse_name): catch destroyed nodes or signals that don't actually support details. * gobject.[hc]: got rid of property trailers. nuked GObject properties "data" and the "signal" variants. (g_object_connect): new convenience function to do multiple signal connections at once. (g_object_disconnect): likewise, for disconnections. * gparam.[hc] (g_param_spec_pool_lookup): took out trailer support. * gvalue.[hc]: marked g_value_fits_pointer() and g_value_peek_pointer() as private (the latter got renamed from g_value_get_as_pointer()). Wed Mar 7 09:32:06 2001 Tim Janik <timj@gtk.org> * glib-object.h: add gvaluearray.h. * gstring.[hc]: fixup naming of g_string_sprint*. * gtypes.h: fixed GCompareDataFunc naming.

Tue Oct 24 23:10:26 2000 Tim Janik <timj@gtk.org> * glib-genmarshal.1: * glib-genmarshal.c: added publically installed marshaller generator. * gtype.h: added G_TYPE_INSTANCE_GET_INTERFACE() to retrive a certain interface VTable from instances.

(g_cclosure_new_object): convenience function to create C closures that have an object as data argument. (g_closure_new_object): convenience function to create closures that have an object as data argument. * gclosure.[hc]: implementation of GClosure mechanism. a closure is basically an encapsulation of a callback function and its environment. ideally, most places supporting callback functions will simply take a GClosure* pointer and thus unify callback environments wrg destroy notification etc. GClosure provides destroy notifiers for arbitrary data pointers, reference counting, invalidation notification (it can be invalidated which is merely a deactivate state) and a marshallinbg abstraction.

Sat Oct 21 02:49:56 2000 Tim Janik <timj@gtk.org> * gtype.c (g_type_conforms_to): this function basically behaves like and is_a check, except that it _additionally_ features interfaces for instantiatable types. enforce this in the second branch as well (`type' conforms_to `type') even if `type' is not an interface type. Fri Oct 20 15:31:04 2000 Tim Janik <timj@gtk.org> * gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb. * gtype.[hc]: * gobject.c: * gvaluetypes.c: added GTypeValueTable.value_peek_pointer and suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT and G_TYPE_POINTER. Mon Aug 21 04:13:37 2000 Tim Janik <timj@gtk.org> * gbsearcharray.[hc]: long standing needed generic implementation of a binary searchable, sorted and dynamically sized array.

changed prototype of g_boxed_type_register_static() to contain an optional Wed Mar 7 09:36:33 2001 Tim Janik <timj@gtk.org> * gboxed.[hc]: changed prototype of g_boxed_type_register_static() to contain an optional init function and a hint at whether the boxed structure uses ref counting internally. added g_value_set_boxed_take_ownership(). made G_TYPE_BOXED an abstract value type. * genums.[hc]: made G_TYPE_ENUM and G_TYPE_FLAGS abstract value types. * glib-genmarshal.c: argument type changes, preparation for third-party arg specification. * gobject.[hc]: cleaned up get/set property code. added g_strdup_value_contents() to improve warnings. * gparam.[hc]: added g_param_value_convert(), taking over responsibility of the old g_value_convert(). added G_PARAM_LAX_VALIDATION flag so validation alterations may be valid a part of the property setting process. * gparamspecs.[hc]: made value comparisons stable (for sort applications). added GParamSpecValueArray, a param spec for value arrays and GParamSpecClosure. nuked the value exchange functions and GParamSpecCCallback. * gtype.[hc]: catch unintialized usages of the type system with g_return_val_if_uninitialized(). introduced G_TYPE_FLAG_VALUE_ABSTRACT to flag types that introduce a value table, but can't be used for g_value_init(). cleaned up reserved type ids. * gvalue.[hc]: code cleanups and saner checking. nuked the value exchange API. implemented value transformations, we can't really "convert" values, rather transforms are an anylogy to C casts, real conversions need a param spec for validation, which is why g_param_value_convert() does real conversions now. * gvaluearray.[hc]: new files that implement a GValueArray, a struct that can hold inhomogeneous arrays of value (to that extend that it also allowes undefined values, i.e. G_VALUE_TYPE(value)==0). this is exposed to the type system as a boxed type. * gvaluetransform.c: new file implementing most of the former value exchange functions as single-sided transformations. * gvaluetypes.[hc]: nuked G_TYPE_CCALLBACK, added g_value_set_string_take_ownership(). * *.h: s/G_IS_VALUE_/G_VALUE_HOLDS_/. * *.[hc]: many fixes and cleanups. * many warning improvements. Tue Feb 27 18:35:15 2001 Tim Janik <timj@gtk.org> * gobject.c (g_object_get_valist): urg, pass G_VALUE_NOCOPY_CONTENTS into G_VALUE_LCOPY(), this needs proper documenting. * gparam.c: fixed G_PARAM_USER_MASK. * gtype.c (type_data_make_W): (type_data_last_unref_Wm): fixed invalid memory freeing. * gobject.c (g_object_last_unref): destroy signal handlers associated with object, right before finalization. * gsignal.c (g_signal_parse_name): catch destroyed nodes or signals that don't actually support details. * gobject.[hc]: got rid of property trailers. nuked GObject properties "data" and the "signal" variants. (g_object_connect): new convenience function to do multiple signal connections at once. (g_object_disconnect): likewise, for disconnections. * gparam.[hc] (g_param_spec_pool_lookup): took out trailer support. * gvalue.[hc]: marked g_value_fits_pointer() and g_value_peek_pointer() as private (the latter got renamed from g_value_get_as_pointer()). Wed Mar 7 09:32:06 2001 Tim Janik <timj@gtk.org> * glib-object.h: add gvaluearray.h. * gstring.[hc]: fixup naming of g_string_sprint*. * gtypes.h: fixed GCompareDataFunc naming. Wed Mar 7 09:33:27 2001 Tim Janik <timj@gtk.org> * gobject/Makefile.am: shuffled rules to avoid excessive rebuilds. * gobject/gobject-sections.txt: updates. * gobject/tmpl/*: bunch of updates, added another patch from Eric Lemings <eric.b.lemings@lmco.com>.

Mon Oct 23 08:28:15 2000 Tim Janik <timj@gtk.org> * gobject.[hc]: new functions for closure maintenance: (g_object_watch_closure): maintain validity of the object and the closure for objects that are used as data part of a closure. (g_cclosure_new_object): convenience function to create C closures that have an object as data argument. (g_closure_new_object): convenience function to create closures that have an object as data argument. * gclosure.[hc]: implementation of GClosure mechanism. a closure is basically an encapsulation of a callback function and its environment. ideally, most places supporting callback functions will simply take a GClosure* pointer and thus unify callback environments wrg destroy notification etc. GClosure provides destroy notifiers for arbitrary data pointers, reference counting, invalidation notification (it can be invalidated which is merely a deactivate state) and a marshallinbg abstraction.

Sat Oct 21 02:49:56 2000 Tim Janik <timj@gtk.org> * gtype.c (g_type_conforms_to): this function basically behaves like and is_a check, except that it _additionally_ features interfaces for instantiatable types. enforce this in the second branch as well (`type' conforms_to `type') even if `type' is not an interface type. Fri Oct 20 15:31:04 2000 Tim Janik <timj@gtk.org> * gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb. * gtype.[hc]: * gobject.c: * gvaluetypes.c: added GTypeValueTable.value_peek_pointer and suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT and G_TYPE_POINTER.

ValueTables get inherited from parent types, unless overridden through the GTypeInfo structure. internally, GTypeValueTable support means an added overhead of one pointer per static or used dynamic type node. g_type_add_class_cache_func(): provide a cache_func/data pair to be called prior to a type nodes last_unref() function, this can be used to prevent premature class destruction. multiple installed cache_func() will be chained upon last_unref() untill one of them returns TRUE. the cache_func()s have to check the type id passed in to figure whether they actually wants to cache the class of this type (since any types are routed through the cache_func() chain). g_type_remove_class_cache_func(): remove a previously installed cache_func/data pair. the cache maintained by this function has to be clear when calling g_type_remove_class_cache_func() to avoid leaks. g_type_class_unref_uncached(): class unref function for cache_func() implementations, unreferences a class omitting the cache chain (and therefore unref->cache->unref->... loops). * gvaluetypes.[hc]: provide the value setters/getters for the primitive fundamental types boolean, char, uchar, int, uint, long, ulong, float, double and string. * gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a GTypeValueTable is provided for this type. removed g_value_init_default(), g_value_validate(), g_value_defaults(), g_value_set_default() and g_values_cmp() as these are supplied by the GParamSpec API now. moved g_values_exchange() into the "implementation details" section, since it just provides the underlying functionality for g_value_convert(). * gvaluecollector.h: renamed the varargs value container from GParamCValue to GTypeCValue as the value collection methods are supplied by the type system now. G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a GParamSpec structure now. * genums.h: macros cleanups/fixes. * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type and assorted g_value_{s|g}et_{enum|flags}() implementations. * gobject.[hc]: provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods and g_value_{s|g}et_object(). * gparam.[hc]: reduced class to value_set_default(), value_validate() and values_cmp(). also parameters now need to fill in a GType value_type; field to indicate the GValue type they are handling. provide g_param_value_set_default(), g_param_value_defaults(), g_param_value_validate() and g_param_values_cmp(). * gparamspecs.[hc]: got rid of the g_value_* functions and the G_IS_VALUE_* macros. adapted param spec implementations according to the GParamSpecClass changes.

(g_cclosure_new_object): convenience function to create C closures that have an object as data argument. (g_closure_new_object): convenience function to create closures that have an object as data argument. * gclosure.[hc]: implementation of GClosure mechanism. a closure is basically an encapsulation of a callback function and its environment. ideally, most places supporting callback functions will simply take a GClosure* pointer and thus unify callback environments wrg destroy notification etc. GClosure provides destroy notifiers for arbitrary data pointers, reference counting, invalidation notification (it can be invalidated which is merely a deactivate state) and a marshallinbg abstraction. GCClosure is also provided in these files, they present a specialized GClosure implementation for C language callbacks. * genum.c: macro cleanups. * gboxed.[hc]: new files, for boxed type abstraction. (g_boxed_copy): copy a boxed structure (g_boxed_free): free a boxed structure (g_value_set_boxed): (g_value_get_boxed): standard GValue functions for boxed types (g_boxed_type_register_static): convenience function for easy introduction of new G_TYPE_BOXED derivatives. * gparam.[hc]: introduced g_param_type_register_static(), a short hand for creation of new GParamSpec derived types. * gtype.[hc]: many fixes, introduced ability to flag individual type nodes as ABSTRACT upon registration, added value_peek_pointer() to the value table to peek at GValue contents as a pointer for types that support this. fixed up GValue checks. * gvalue.[hc]: added g_value_fits_pointer() and g_value_get_as_pointer() to peek at the value contents as pointer. * *.[hc]: adaptions to type macro fixes and changes in the type registration API. * many const corrections over the place.

GTypeValueTable contains the following members: value_init(): initialize a GValue structure. value_free(): free GValue structure contents (optional). value_copy(): copy one GValue contents to another GValue structure of collect_type: varargs collection type for the first variable argument to be collected by collect_value(). collect_value(): variable arguments collection function (optional). lcopy_type: varargs collection type for the first variable argument to be location copyied by lcopy_value(). lcopy_value(): variable arguments location copy function (optional). g_type_value_table_peek(): new function to retrive the GTypeValueTable* for a type node. ValueTables get inherited from parent types, unless overridden through the GTypeInfo structure. internally, GTypeValueTable support means an added overhead of one pointer per static or used dynamic type node. g_type_add_class_cache_func(): provide a cache_func/data pair to be called prior to a type nodes last_unref() function, this can be used to prevent premature class destruction. multiple installed cache_func() will be chained upon last_unref() untill one of them returns TRUE. the cache_func()s have to check the type id passed in to figure whether they actually wants to cache the class of this type (since any types are routed through the cache_func() chain). g_type_remove_class_cache_func(): remove a previously installed cache_func/data pair. the cache maintained by this function has to be clear when calling g_type_remove_class_cache_func() to avoid leaks. g_type_class_unref_uncached(): class unref function for cache_func() implementations, unreferences a class omitting the cache chain (and therefore unref->cache->unref->... loops). * gvaluetypes.[hc]: provide the value setters/getters for the primitive fundamental types boolean, char, uchar, int, uint, long, ulong, float, double and string. * gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a GTypeValueTable is provided for this type. removed g_value_init_default(), g_value_validate(), g_value_defaults(), g_value_set_default() and g_values_cmp() as these are supplied by the GParamSpec API now. moved g_values_exchange() into the "implementation details" section, since it just provides the underlying functionality for g_value_convert(). * gvaluecollector.h: renamed the varargs value container from GParamCValue to GTypeCValue as the value collection methods are supplied by the type system now. G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a GParamSpec structure now. * genums.h: macros cleanups/fixes. * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type and assorted g_value_{s|g}et_{enum|flags}() implementations. * gobject.[hc]: provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods and g_value_{s|g}et_object(). * gparam.[hc]: reduced class to value_set_default(), value_validate() and values_cmp(). also parameters now need to fill in a GType value_type; field to indicate the GValue type they are handling. provide g_param_value_set_default(), g_param_value_defaults(), g_param_value_validate() and g_param_values_cmp(). * gparamspecs.[hc]: got rid of the g_value_* functions and the G_IS_VALUE_* macros. adapted param spec implementations according to the GParamSpecClass changes.

Sat Jun 24 23:03:04 2000 Tim Janik <timj@gtk.org> * gtype.[hc]: provide G_TYPE_CHAR, G_TYPE_UCHAR, G_TYPE_BOOLEAN, G_TYPE_INT, G_TYPE_UINT, G_TYPE_LONG, G_TYPE_ULONG, G_TYPE_FLOAT, G_TYPE_DOUBLE and G_TYPE_STRING fundamental types. added a GTypeValueTable* pointer to GTypeInfo structure for types to implement GValue handling functions. GTypeValueTable contains the following members: value_init(): initialize a GValue structure. value_free(): free GValue structure contents (optional). value_copy(): copy one GValue contents to another GValue structure of collect_type: varargs collection type for the first variable argument to be collected by collect_value(). collect_value(): variable arguments collection function (optional). lcopy_type: varargs collection type for the first variable argument to be location copyied by lcopy_value(). lcopy_value(): variable arguments location copy function (optional). g_type_value_table_peek(): new function to retrive the GTypeValueTable* for a type node. ValueTables get inherited from parent types, unless overridden through the GTypeInfo structure. internally, GTypeValueTable support means an added overhead of one pointer per static or used dynamic type node. g_type_add_class_cache_func(): provide a cache_func/data pair to be called prior to a type nodes last_unref() function, this can be used to prevent premature class destruction. multiple installed cache_func() will be chained upon last_unref() untill one of them returns TRUE. the cache_func()s have to check the type id passed in to figure whether they actually wants to cache the class of this type (since any types are routed through the cache_func() chain). g_type_remove_class_cache_func(): remove a previously installed cache_func/data pair. the cache maintained by this function has to be clear when calling g_type_remove_class_cache_func() to avoid leaks. g_type_class_unref_uncached(): class unref function for cache_func() implementations, unreferences a class omitting the cache chain (and therefore unref->cache->unref->... loops). * gvaluetypes.[hc]: provide the value setters/getters for the primitive fundamental types boolean, char, uchar, int, uint, long, ulong, float, double and string. * gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a GTypeValueTable is provided for this type. removed g_value_init_default(), g_value_validate(), g_value_defaults(), g_value_set_default() and g_values_cmp() as these are supplied by the GParamSpec API now. moved g_values_exchange() into the "implementation details" section, since it just provides the underlying functionality for g_value_convert(). * gvaluecollector.h: renamed the varargs value container from GParamCValue to GTypeCValue as the value collection methods are supplied by the type system now. G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a GParamSpec structure now. * genums.h: macros cleanups/fixes. * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type and assorted g_value_{s|g}et_{enum|flags}() implementations. * gobject.[hc]: provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods and g_value_{s|g}et_object(). * gparam.[hc]: reduced class to value_set_default(), value_validate() and values_cmp(). also parameters now need to fill in a GType value_type; field to indicate the GValue type they are handling. provide g_param_value_set_default(), g_param_value_defaults(), g_param_value_validate() and g_param_values_cmp(). * gparamspecs.[hc]: got rid of the g_value_* functions and the G_IS_VALUE_* macros. adapted param spec implementations according to the GParamSpecClass changes.

changed prototype of g_boxed_type_register_static() to contain an optional Wed Mar 7 09:36:33 2001 Tim Janik <timj@gtk.org> * gboxed.[hc]: changed prototype of g_boxed_type_register_static() to contain an optional init function and a hint at whether the boxed structure uses ref counting internally. added g_value_set_boxed_take_ownership(). made G_TYPE_BOXED an abstract value type. * genums.[hc]: made G_TYPE_ENUM and G_TYPE_FLAGS abstract value types. * glib-genmarshal.c: argument type changes, preparation for third-party arg specification. * gobject.[hc]: cleaned up get/set property code. added g_strdup_value_contents() to improve warnings. * gparam.[hc]: added g_param_value_convert(), taking over responsibility of the old g_value_convert(). added G_PARAM_LAX_VALIDATION flag so validation alterations may be valid a part of the property setting process. * gparamspecs.[hc]: made value comparisons stable (for sort applications). added GParamSpecValueArray, a param spec for value arrays and GParamSpecClosure. nuked the value exchange functions and GParamSpecCCallback. * gtype.[hc]: catch unintialized usages of the type system with g_return_val_if_uninitialized(). introduced G_TYPE_FLAG_VALUE_ABSTRACT to flag types that introduce a value table, but can't be used for g_value_init(). cleaned up reserved type ids. * gvalue.[hc]: code cleanups and saner checking. nuked the value exchange API. implemented value transformations, we can't really "convert" values, rather transforms are an anylogy to C casts, real conversions need a param spec for validation, which is why g_param_value_convert() does real conversions now. * gvaluearray.[hc]: new files that implement a GValueArray, a struct that can hold inhomogeneous arrays of value (to that extend that it also allowes undefined values, i.e. G_VALUE_TYPE(value)==0). this is exposed to the type system as a boxed type. * gvaluetransform.c: new file implementing most of the former value exchange functions as single-sided transformations. * gvaluetypes.[hc]: nuked G_TYPE_CCALLBACK, added g_value_set_string_take_ownership(). * *.h: s/G_IS_VALUE_/G_VALUE_HOLDS_/. * *.[hc]: many fixes and cleanups. * many warning improvements. Tue Feb 27 18:35:15 2001 Tim Janik <timj@gtk.org> * gobject.c (g_object_get_valist): urg, pass G_VALUE_NOCOPY_CONTENTS into G_VALUE_LCOPY(), this needs proper documenting. * gparam.c: fixed G_PARAM_USER_MASK. * gtype.c (type_data_make_W): (type_data_last_unref_Wm): fixed invalid memory freeing. * gobject.c (g_object_last_unref): destroy signal handlers associated with object, right before finalization. * gsignal.c (g_signal_parse_name): catch destroyed nodes or signals that don't actually support details. * gobject.[hc]: got rid of property trailers. nuked GObject properties "data" and the "signal" variants. (g_object_connect): new convenience function to do multiple signal connections at once. (g_object_disconnect): likewise, for disconnections. * gparam.[hc] (g_param_spec_pool_lookup): took out trailer support. * gvalue.[hc]: marked g_value_fits_pointer() and g_value_peek_pointer() as private (the latter got renamed from g_value_get_as_pointer()). Wed Mar 7 09:32:06 2001 Tim Janik <timj@gtk.org> * glib-object.h: add gvaluearray.h. * gstring.[hc]: fixup naming of g_string_sprint*. * gtypes.h: fixed GCompareDataFunc naming.
