gimp r26013 - in trunk: . app/widgets



Author: mitch
Date: Sat Jun 28 19:01:25 2008
New Revision: 26013
URL: http://svn.gnome.org/viewvc/gimp?rev=26013&view=rev

Log:
2008-06-28  Michael Natterer  <mitch gimp org>

	This is completely evil:

	* app/widgets/Makefile.am
	* app/widgets/gimpscalebutton.[ch]: copy GtkScaleButton from GTK+
	upstream trunk and hack around until symbol conflicts are gone
	and it builds.

	* app/widgets/gimppropwidgets.c
	* app/widgets/gtkscalebutton.[ch]: use the hacked version instead
	of the one from GTK+. Set the orientation to horizontal.
