Change groupbox margins in Qt Fusion theme?
This is a duplicate of http://stackoverflow.com/q/27947128/314290 which didn't get much attention, perhaps because all the cool people are here.
I want to use the Fusion theme, but it adds ugly margins around group boxes. How do I remove or reduce the margins around the group boxes? Changes that I made in Qt creator don't seem to stick.
