Detailed Description

popup text balloons above instance of vtkProp when hovering occurs

The vtkBalloonWidget is used to popup text and/or an image when the mouse hovers over an instance of vtkProp. The widget keeps track of (vtkProp,vtkBalloon) pairs (where the internal vtkBalloon class is defined by a pair of vtkStdString and vtkImageData), and when the mouse stops moving for a user-specified period of time over the vtkProp, then the vtkBalloon is drawn nearby the vtkProp. Note that an instance of vtkBalloonRepresentation is used to draw the balloon.

To use this widget, specify an instance of vtkBalloonWidget and a representation (e.g., vtkBalloonRepresentation). Then list all instances of vtkProp, a text string, and/or an instance of vtkImageData to be associated with each vtkProp. (Note that you can specify both text and an image, or just one or the other.) You may also wish to specify the hover delay (i.e., set in the superclass vtkHoverWidget).

Event Bindings:

By default, the widget observes the following VTK events (i.e., it watches the vtkRenderWindowInteractor for these events):

  MouseMoveEvent - occurs when mouse is moved in render window.
  TimerEvent - occurs when the time between events (e.g., mouse move)
               is greater than TimerDuration.
  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 vtkBalloonWidget's widget events:

  vtkWidgetEvent::Move -- start the timer
  vtkWidgetEvent::TimedOut -- when hovering occurs,
  vtkWidgetEvent::SelectAction -- activate any callbacks associated
                                  with the balloon.

Event Bindings:

This widget invokes the following VTK events on itself (which observers can listen for):

  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).
