From 58f8dd4f92e0e647ed530554d7edf3d1a901f552 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?B=C5=82a=C5=BCej=20Szczygie=C5=82?= Date: Fri, 15 Jan 2016 02:29:57 +0100 Subject: QtWidgets: Allow to cover up the window container by another widget When the window container already has a window handle, allow embedded windows to use this handle as a parent.
