Since we can't use an input and visual transparent widget, like a GtkGrid, we have to implement input forwarding in the QWindow. Using a Qt5Widget directly results in other problems on Qt 5.12+, like these warnings (depending on the tested Qt::WA_* flags): * Attempted flush to non-raster surface QWidgetWindow(0xa386c10, name="QWidgetClassWindow") of type QSurface::OpenGLSurface (consider using Qt::WA_PaintOnScreen to exclude from backingstore sync) * QWidget::paintEngine: Should no longer be called So the current QWidget::createWindowContainer has to stay and key and mouse handling must be implemented as in Qt5Widget. And the QWindow is strangely not accessible through the windowHandle() of the container QWwidget. As a result this patch is mostly boilerplate code, publishing the Qt5Widget mouse and key handling as static functions.
