public class ComponentWidget
extends Widget

This widget allows to use an AWT/Swing component in the scene. The widget itself just represents and reserve the place occupied by the component. When a component is resized, then reserved place is recalculated. The component placement is automatically update based on the placement of the widget. The widget also paints the component in the satelite views.

When a widget is added into the scene, it has to attach a scene listener for automatic recalculation. The attaching is done automatically for the first time.
