Member Function Documentation

template<class ZP, int maxzoom> void ZoomDecorator< ZP, maxzoom >::get_boundrect (  double &  , double &  , double &  , double &  )  [virtual]

This function should be overloaded in every node to provide for event handling and repaint. Implements BaseSceneNode.

Here is the call graph for this function:

template<class ZP, int maxzoom> bool ZoomDecorator< ZP, maxzoom >::check_event_fitspixels (  Event *   )  [virtual]

This function should be overloaded in every node to provide for event handling. Implements BaseSceneNode.

Here is the call graph for this function:

template<class ZP, int maxzoom> bool ZoomDecorator< ZP, maxzoom >::handle_event (  Event *   )  [virtual]

call the base event handler in all nodes because it provides checks for node visibility and mouse event fitting into bounding rectangle. Reimplemented from BaseSceneNode.

Here is the call graph for this function:

template<class ZP, int maxzoom> void ZoomDecorator< ZP, maxzoom >::set_parent (  SceneNode *   )

template<class ZP, int maxzoom> void ZoomDecorator< ZP, maxzoom >::listen_event (  Event *  e  )  [virtual]

Reimplemented from EventListener.

Here is the call graph for this function:

template<class ZP, int maxzoom> void ZoomDecorator< ZP, maxzoom >::appear (  Event *  e  )
