Detailed Description

This class rotates a widget by one turn.

This method rotates a widget. The rotation-speed can be set by the XML-file. The method void animate( MenuObject *obj ) performs a full rotation. The method unanimate ( MenuObject *obj ) has nothing to do, because the method void animate( MenuObject *obj ) leaves the widget in its origin position already.

This animation uses a continuously movement, which is simulated by many very small movement steps. This cannot be done directly in this class, because the animate( MenuObject *obj ) and unanimate( MenuObject *obj ) methods have to return very quickly. So instead of animating the widget, a new object is created, which uses QueuedThread as superclass. This new object is put into the ThreadQueue -class, which performs the animation in an own thread. The ThreadQueue -class deletes this object automatically, when the animation has finished.
