From f062e50fe69e01376b6ebf7ade8402b782620ac3 Mon Sep 17 00:00:00 2001 From: Stefan Haller Date: Sat, 22 Sep 2012 09:46:48 +0200 Subject: [PATCH] gitk: Work around empty back and forward images when buttons are disabled On Mac, the back and forward buttons show an empty rectange instead of a grayed-out arrow when they are disabled. The reason is a Tk bug on Mac that causes disabled images not to draw correctly (not to draw at all, that is); see . To work around this, we explicitly provide gray images for the disabled state; I think this looks better than the default stipple effect that you get on Windows as well, but that may be a matter of taste.
