/**

 Creates pseudo-transparent widgets.
 A pseudo-transparent widget is a widget with its background pixmap set to
 that part of the desktop background that it is currently obscuring. This
 gives a transparency effect.
 To create a transparent widget, construct a KRootPixmap and pass it a
 pointer to your widget. That's it! Moving, resizing and background changes
 are handled automatically.
 Instead of using the default behavior, you can ask KRootPixmap
 to emit a backgroundUpdated(TQPixmap) signal whenever
 the background needs updating by using setCustomPainting(boolean).
 Alternatively by reimplementing updateBackground(KSharedPixmap)
 you can take complete control of the behavior.
 See {@link KRootPixmapSignals} for signals emitted by KRootPixmap
