2004-03-08  Federico Mena Quintero  <federico@ximian.com>

	Fixes #136105.

	* gtk/gtkfilechooserembed.h (struct _GtkFileChooserEmbedIface):
	Added an ::initial_focus() method.

	* gtk/gtkfilechooserembed.c
	(_gtk_file_chooser_embed_delegate_iface_init): Set the
	initial_focus method.
	(delegate_initial_focus): Implement.
	(_gtk_file_chooser_embed_initial_focus): New function.

	* gtk/gtkfilechooserdialog.c
	(gtk_file_chooser_dialog_constructor): Call
	_gtk_file_chooser_embed_initial_focus().

	* gtk/gtkfilechooserdefault.c (gtk_file_chooser_default_init):
	Install the ::initial_focus() handler.
	(gtk_file_chooser_default_initial_focus): Implement.
