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.
