Fri Apr 24 01:29:04 1998 Tim Janik <timj@gtk.org>
* gtk/gtkaccelerator.h (struct _GtkAcceleratorTable): changed ref_count
field to be of type guint.
* gtk/gtkaccelerator.c (gtk_accelerator_table_unref): added check for
ref_count>0;
(gtk_accelerator_table_install): keep a per object list of accelerator
tables that refer to this object.
(gtk_accelerator_table_remove): remove the accelerator table from the
per object list.
(gtk_accelerator_table_clean): warn if there are any object references
left in an accelerator table upon destruction.
(gtk_accelerator_tables_delete): new function to delete object
references from the accelerator tables associated with this object.
* gtk/gtkwidget.c (gtk_widget_class_init): changed emission of
GtkWidget::install_accelerator to GTK_RUN_LAST so the installation
of an accelerator can be prevented by gtk_signal_emit_stop().
(gtk_widget_real_destroy): call gtk_accelerator_tables_delete (),
so there are no stale pointers in accelerator tables left.
this change is binary compatible, so just touch gtkaccelerator.h -r gtkwidget.h
