From bb696453f6f87cad58982af3455335478fedb8cc Mon Sep 17 00:00:00 2001 From: Eskil Abrahamsen Blomfeldt Date: Wed, 11 Aug 2010 11:49:35 +0200 Subject: Disable minRightBearing optimization in QTextLayout on Mac Neither of the Mac font engines have implemented minimum right bearing, which will cause them to return 0 for the minimum value. This will cause the right bearing to never be calculated prior to breaking and thus never be a part of the breaking width. Since actually implementing the functions is too time consuming for right now, we will disable the optimization for the time being.
