// .NAME vtkWidgetEventTranslator - map VTK events into widget events
// .SECTION Description
// vtkWidgetEventTranslator maps VTK events (defined on vtkCommand) into
// widget events (defined in vtkWidgetEvent.h). This class is typically used
// in combination with vtkWidgetCallbackMapper, which is responsible for
// translating widget events into method callbacks, and then invoking the
// callbacks.
//
// This class can be used to define different mappings of VTK events into
// the widget events. Thus widgets can be reconfigured to use different
// event bindings.
