-
-       The animator only ever animates widgets that have been added to this layout. If a widget
-       is deleted during animation, the widget's destructor removes the widget form this layout.
-       This in turn aborts the animation (see takeAt()) and this signal will never be delivered.
-
-       If the widget is deleted after the animation is finished but before this qeued signal
-       is delivered, the widget is no longer in the layout and we catch it here. The key is that
-       QMainWindowLayoutState::contains() never dereferences the pointer. */
