From 474af0a61d6154006966a775d186687aa8881708 Mon Sep 17 00:00:00 2001 From: Friedemann Kleint Date: Thu, 21 Jan 2016 08:15:18 +0100 Subject: QWidget::mapTo/FromGlobal(): Rewrite using a QTransform. Introduce a function going up the widget hierarchy determining a QTransform for mapping the coordinates applying the transformations of any QGraphicsView instances found. In mapFromGlobal(), use the inverse of it. This fixes the case of widget hierarchies embedded into QGraphicsView with transformations. Increase fuzz in the tests due to float rounding errors.
