This function is called by the layout engine after it has updated the position (in variables x and y) and the size (in properties width and height) to give you a chance to update the actual position of the native child window (if there is one) or whatever.
It is also responsible for calling sendResizeEvent to notify other listeners that the widget has changed size.
