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.

(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.

fixed dealing with collection/lcopy of NULL values. Mon Dec 11 04:44:11 2000 Tim Janik <timj@gtk.org> * gboxed.c: fixed dealing with collection/lcopy of NULL values. * gclosure.h: removed insane ramblings, added G_CALLBACK() a casting convenience macro. * Makefile.am: cleanups, marshaller generation rules. * gmarshal.[hc]: new files with GRuntime standard marshallers. * glib-genmarshal.c: fix log domain, support gruntime standard marshallers, suport G_TYPE_PARAM, come with extern "C" and #include gmarshal.h. * glib-genmarshal.1: reflect glib-genmarshal.c updates. * gobject.[hc]: implement object constructor. rework parameter changed notification queueing, we support queue freezes now and don't dispatch from an idle handler anymore. parameter->property rename hassle. implemented ::properties_changed and ::notify::* signals for property change notification (the later supports property names as details). added signal connection and named data properties. (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_freeze_notify): start queueing of property changes (freeze/ thaw calls stack). (g_object_notify): announce changes of a certain property directly. (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_connect_closure): closure connection variant that works from signal name+detail. (g_signal_connect_data): c handler connection variant that works from signal name+detail. (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.

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.
