the Plasma widgets are just subclasses of QGraphicsProxyWidget that give us three things: * provide a set API for accessing the widgets that is easy to use from scripts * give us a central place to do cool Plasma Things like the button glows. * allow us to avoid writing the same half dozen lines of code over and over, e.g.: QGraphicsProxyWidget *proxy = new QGraphicsProxyWidget(this); KPushButton *button = new KPushButton(); proxy->setWidget(button); etc.. this just becomes: Plasma::PushButton *button = new Plasma::PushButton(this); internally, however, it's still just a QGraphicsProxyWidget with a KPushButton. > 1.
