    Description

      QQuickWindow is a class for displaying QML content. I can draw my data under qml using QQuickWindow::beforeRendering() signal and raw OpenGL commands. But I can't do the same beforeRendering() drawing in QQuickWidget - please add such a signal.

      I have downloaded qt 5.5 beta and can easily access beforeRendering. However it's functionality is severe limited: QQuickWidget::update do not repaint QQuickWidget framebuffer and do not emit QQuickWidget::quickWindow::beforeRendering signal. The signal is emitted only if something in qml scene changed.
