2000-08-30 Havoc Pennington <hp@pobox.com> * gtk/gtkmarshal.list: Add marshallers for changed GtkTextBuffer signals. * gtk/gtktextbuffer.h: Add "interactive" arg to insert_text and delete_text signals. This allows the signals to be used for implementing undo. * gtk/gtktextbuffer.c: Change signal handler signatures; provide "interactive" argument when emitting insert_text or delete_text signal.
