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.

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.

Mon Apr 17 20:45:50 2000 Tim Janik <timj@gtk.org> * glib-gobject.c (g_object_base_class_finalize): oops, don't unset n_params prior to destructing them. Tue Apr 11 04:28:10 2000 Tim Janik <timj@gtk.org> * fixed a couple of bugs in the initial parameter/object implementations, after getting beast running on GObject and GValue. Fri Apr 7 04:27:49 2000 Tim Janik <timj@gtk.org> * glib-gobject.[hc]: completed parameter set/get implementations, along with asyncronous parameter changed notification queue. Sun Apr 2 04:54:36 2000 Tim Janik <timj@gtk.org> * glib-gobject.[hc]: GObject implementation, that is facilities for setting/getting quarked data and reference counting. * glib-gparamspecs.[hc]: first actuall parameter implementations for GLib, so far we have: char, uchar, bool, int, uint, long, ulong, enum, flags, float, double, string and object. each of these GParamSpecs is a new instantiatable type in its own respect, so the .c file derives 13 new types from G_TYPE_PARAM and defines over 50 (*2) conversion facilities. * glib-gvaluecollector.h: generic varargs handling stubs for GParamSpecs, private header file (does get installed for inclusion into user code though). * glib-gvalue.[hc]: GValue functionality implementation. * glib-gparam.[hc]: basis GParamSpec implementation for the virtual base type G_TYPE_PARAM. * glib-genums.[hc]: enum/flags type implementation, based on bseenum.[hc]. * glib-extra.[hc]: GLib additions, including 1.3 compatibility routines and various other functions, from string manipulation over list manipulation up to a unix signal GSource. * glib-gtype.[hc]: GLib Type System implementation, heavily based on BSE's dynamic type system.

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_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.

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.

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.

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.
