It is possible that the widget consists of more as one graphical widget, then all of it should be redrawn. It is possible that some data are set in another thread, they should be applied to the widgets firstly. It is possible that the widget is removed though a repaintGthread-order is pending from the time before deleting, for example if the graphic layout is changed.
