+    Calling this function with \a enable set to true will enable a feature that

+    one go. It will propagate up the parentLayoutItem() hierarchy until it has
+    reached the root. If the root item is a QGraphicsWidget, it will *post* a

+    invalid (not activated). This is the recommended behaviour.
+
+    If not set it will also propagate up the parentLayoutItem() hierarchy, but

+    request to the widget. When the layout request is consumed, this might
+    cause it to continue propagation up to the parentLayoutItem() of the
