* Added support for floating windows and context menus in QMDIAreas. * Protected the size (_width and _height) by a mutex to prevent threading problems. Then my own: * Made sure the embedded widget's size follows the graphicsView's size at all times so that window resizes will resize the widget as expected in fullscreen mode."
