Detailed Description

map widget events into callbacks

vtkWidgetCallbackMapper maps widget events (defined in vtkWidgetEvent.h) into static class methods, and provides facilities to invoke the methods. This class is templated and meant to be used as an internal helper class by the widget classes. The class works in combination with the class vtkWidgetEventTranslator, which translates VTK events into widget events.

void vtkWidgetCallbackMapper::SetCallbackMethod	(	unsigned long	VTKEvent,
		unsigned long	widgetEvent,
		vtkAbstractWidget *	w,
		CallbackType	f
	)

This class works with the class vtkWidgetEventTranslator to set up the initial coorespondence between VTK events, widget events, and callbacks.

Different flavors of the SetCallbackMethod() are available depending on what sort of modifiers are to be associated with a particular event. Typically the widgets should use this method to set up their event callbacks. If modifiers are not provided (i.e., the VTKEvent is a unsigned long eventId) then modifiers are ignored. Otherwise, a vtkEvent instance is used to fully quality the events.

void vtkWidgetCallbackMapper::InvokeCallback ( unsigned long widgetEvent )

This method invokes the callback given a widget event.

A non-zero value is returned if the listed event is registered.

		vtkAbstractWidget *	w,
		CallbackType	f
	)

protected

This method is used to assign a callback (implemented as a static class method) to a particular widget event.

This is an internal method used by widgets to map widget events into invocations of class methods.
