added an event watcher for enter/leave based on signal emission hooks.
Mon Nov 30 06:20:36 1998 Tim Janik <timj@gtk.org>
* gtk/testgtk.c: added an event watcher for enter/leave based on
signal emission hooks.
* gtk/gtkobject.c (gtk_object_class_init): made GtkObject::destroy a
GTK_RUN_NO_HOOKS signal.
* gtk/gtksignal.h:
* gtk/gtksignal.c: implemented emission hooks, new hooks can be added
to a signal with gtk_signal_add_emission_hook or
gtk_signal_add_emission_hook_full, and can be removed again with
gtk_signal_remove_emission_hook.
* gtk/gtkenums.h: remove GTK_RUN_MASK, since it doesn't represent
an appropriate mask for signal runtypes for a long time now.
added GTK_RUN_NO_HOOKS value, which is used to flag signals
that do not allow the running of signal hooks.
