// .NAME vtkWidgetCallbackMapper - map widget events into callbacks
// .SECTION Description
// 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.
//

// Description:
// 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.
