From 9a33a0027883ab77c10d8a9d9d9df5b4c2c5d50b Mon Sep 17 00:00:00 2001 From: Jens Bache-Wiig Date: Fri, 27 Mar 2009 15:29:54 +0100 Subject: Style QDial to look better This widget has been needing an update in appearance for years as it is still featured in our style gallery. This introduces a new and better looking nob control to cleanlooks, gtk, mac, windows xp, vista and cleanlooks.
