Chris Toshok 68b8639345 fix c&p typo. 
2002-11-16  Chris Toshok  <toshok@ximian.com>

	* gal/widgets/e-reflow.c (e_reflow_class_init): fix c&p typo.

	* gal/widgets/e-categories-master-list-dialog.c: switch to
	GtkDialogism's.

	* gal/widgets/gal-categories.[ch]: same.

	* gal/widgets/e-categories-master-list-dialog.glade: libglade-convert.

	* gal/widgets/e-categories.glade: same.

	* gal/util/e-text-event-processor.[ch]: subclass this from
	GObject.

	* gal/util/e-text-event-processor-emacs-like.[ch]: clean up the
	gtk cruft a bit.

	* gal/e-text/e-text.c (_get_tep): remove the _sink call.
	(e_text_init): same.

	* gal/e-text/e-text-model.[ch]: subclass this from GObject instead
	of GtkObject.
