From 9720efbd1035c2e939b0581163e6d804c713dd96 Mon Sep 17 00:00:00 2001 From: Friedemann Kleint Date: Tue, 21 Jul 2015 16:00:38 +0200 Subject: Diaglib: Add class DebugProxyStyle. Add a debug proxy style that wraps around an existing style and outputs the parameters and return values of its function calls, for debugging QStyle.
