Thu Mar 8 00:02:30 2001 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.[ch] (gtk_widget_get_name): Make G_CONST_RETURN. * gtk/gtkwidget.[ch] gtk/gtkprivate.h: Add a ::hierarchy-changed signal when a widget changes from anchored to unanchored or vice versa. (anchored means gtk_widget_get_ancestor (widget, GTK_TYPE_WINDOW) != NULL.) Use a private flag to keep track of this efficiently.
