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.
