+    Returns the offscreen QQuickWindow which is used by this widget to drive
+    the Qt Quick rendering. This is useful if you want to use QQuickWindow
+    APIs that are not currently exposed by QQuickWidget, for instance
+    connecting to the QQuickWindow::beforeRendering() signal in order
+    to draw native OpenGL content below Qt Quick's own rendering.
+
+    \warning Use the return value of this function with caution. In
+    particular, do not ever attempt to show the QQuickWindow, and be
+    very careful when using other QWindow-only APIs.
