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).
- Event Bindings:
- By default, the widget observes the following VTK events (i.e., it watches the vtkRenderWindowInteractor for these events):
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).
- Event Bindings:
- Note that the event bindings described above can be changed using this class's vtkWidgetEventTranslator. This class translates VTK events into the vtkHoverWidget's widget events:
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.
- Event Bindings:
- This widget invokes the following VTK events on itself when the widget determines that it is hovering. Note that observers of this widget can listen for these events and take appropriate action.
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).
