// .NAME vtkGenericRenderWindowInteractor - platform-independent programmable render window interactor.

// .SECTION Description
// vtkGenericRenderWindowInteractor provides a way to translate native
// mouse and keyboard events into vtk Events.   By calling the methods on
// this class, vtk events will be invoked.   This will allow scripting
// languages to use vtkInteractorStyles and 3D widgets.

  // Description:
  // Flag that indicates whether the TimerEvent method should call ResetTimer
  // to simulate repeating timers with an endless stream of one shot timers.
  // By default this flag is on and all repeating timers are implemented as a
  // stream of sequential one shot timers. If the observer of
  // CreateTimerEvent actually creates a "natively repeating" timer, setting
  // this flag to off will prevent (perhaps many many) unnecessary calls to
  // ResetTimer. Having the flag on by default means that "natively one
  // shot" timers can be either one shot or repeating timers with no
  // additional work. Also, "natively repeating" timers still work with the
  // default setting, but with potentially many create and destroy calls.
