From 3481db791c3b48e28f1a9531b247adf6562edb71 Mon Sep 17 00:00:00 2001 From: Prasanth Ullattil Date: Thu, 22 Oct 2009 16:39:14 +0200 Subject: Remove internal widgets from QApplication::topLevelWidgets() We have some internal hidden widgets which should not come up in the QApplication::topLevelWidgets() list. So the known ones are being removed from the QWidgetPrivate::allWidgets set. Task-number: QTBUG-739 Reviewed-by: Denis Dzyubenko Reviewed-by: Bradley T.
