New private interface to help negotiate the default size of the widget.
Fri Feb 27 18:46:27 2004 Jonathan Blandford <jrb@redhat.com> * gtk/gtkfilechooserembed.h: New private interface to help negotiate the default size of the widget. Still a bit buggy, but better than the old behavior. * gtk/gtkfilechooserdefault.c: Implement the embed interface. * gtk/gtkfilechooserwidget.c: Proxy the embed interface. * gtk/gtkfilechooserdialog.c: Use the embed interface.
