Color choices for the "phase" style in tree views (e.g. the one in KControl) can result in the tree lines and arrows being invisible if QColorGroup::mid() and QColorGroup::base() are the same (e.g. with the built-in Solaris color scheme).

Solution: use QColorGroup::text() instead of QColorGroup::mid() for drawing, or alternitavely use a modified QColorGroup::base() to maintain the 'softer' style without running into the 'invisible color' problem.
Comment 1 Matthew Woehlke 2006-11-08 20:34:06 UTC 
Here is a patch demonstrating one possible way to fix this (consistent with many styles, but arguably not the 'softer' phase look):
