Wed Jun 10 06:25:17 1998 Tim Janik <timj@gtk.org> * gdk/gdk.c (gdk_init): prevent gdk_init() from segfaulting when invoked with (NULL, NULL); (this worked sometime ago). * gtk/gtktypeutils.h: * gtk/gtktypeutils.c: enum and flags type creation can now be done through gtk_type_register_enum() and gtk_type_register_flags(), which allow to specify the enum value arrays directly. the NULL terminated value arrays can be retrived through gtk_type_enum_get_values() and gtk_type_flags_get_values(); (gtk_type_children_types): new function to query derived types.
