invoke a vtkTimerEvent when hovering
The vtkHoverWidget is used to invoke an event when hovering in a render window. Hovering occurs when mouse motion (in the render window) does not occur for a specified amount of time (i.e., TimerDuration). This class can be used as is (by observing TimerEvents) or for class derivation for those classes wishing to do more with the hover event.
To use this widget, specify an instance of vtkHoverWidget and specify the time (in milliseconds) defining the hover period. Unlike most widgets, this widget does not require a representation (although subclasses like vtkBalloonWidget do require a representation).
MouseMoveEvent - manages a timer used to determine whether the mouse is hovering. TimerEvent - when the time between events (e.g., mouse move), then a timer event is invoked. KeyPressEvent - when the "Enter" key is pressed after the balloon appears, a callback is activated (e.g., WidgetActivateEvent).
vtkWidgetEvent::Move -- start (or reset) the timer vtkWidgetEvent::TimedOut -- when enough time is elapsed between defined VTK events the hover event is invoked. vtkWidgetEvent::SelectAction -- activate any callbacks associated with the balloon.
vtkCommand::TimerEvent (when hovering is determined to occur) vtkCommand::EndInteractionEvent (after a hover has occurred and the mouse begins moving again). vtkCommand::WidgetActivateEvent (when the balloon is selected with a keypress).

Specify the hovering interval (in milliseconds). If after moving the mouse the pointer stays over a vtkProp for this duration, then a vtkTimerEvent::TimerEvent is invoked.
