got rid of g_set_error_handler(), g_set_warning_handler(),

        * glib/gmessages.h: got rid of g_set_error_handler(),
        g_set_warning_handler(), g_set_message_handler().

Wed Sep  5 05:24:07 2001  Tim Janik  <timj@gtk.org>

        * gobject/tmpl/gboxed.sgml: documented some functions.

        * gobject/tmpl/objects.sgml: some fixups.

Mon Sep 10 19:27:47 2001  Tim Janik  <timj@gtk.org>

        * gtype.[hc]:
        g_type_add_interface*(): implement the ability to add an interface to
        a type whose parents already conform to this interface.
        such "overriding" interfaces, when initialized, are not just initialized
        with 0, but with a copy of the interface they override.
        g_type_interface_peek_parent(): new function, return the interface
        that this interface "overrides", if any.

        * testgruntime.c: test new interface stuff.

Mon Sep 10 19:27:47 2001 Tim Janik <timj@gtk.org>
* gtype.[hc]:
g_type_add_interface*(): implement the ability to add an interface to
a type whose parents already conform to this interface.
such "overriding" interfaces, when initialized, are not just initialized
with 0, but with a copy of the interface they override.
g_type_interface_peek_parent(): new function, return the interface
that this interface "overrides", if any.
* testgruntime.c: test new interface stuff.
2001-09-10 Alex Larsson <alexl@redhat.com>
* gobject/gboxed.[ch]:
* gobject/gsourceclosure.c:
Removed is_refcounted and GBoxedInitFunc from
g_boxed_type_register_static().
