vtkCaptionRepresentation

Section: Visualization Toolkit Widget Classes

Usage

This class represents vtkCaptionWidget. A caption is defined by some text with a leader (e.g., arrow) that points from the text to a point in the scene. The caption is defined by an instance of vtkCaptionActor2D. It uses the event bindings of its superclass (vtkBorderWidget) to control the placement of the text, and adds the ability to move the attachment point around. In addition, when the caption text is selected, the widget emits a ActivateEvent that observers can watch for. This is useful for opening GUI dialogoues to adjust font characteristics, etc. (Please see the superclass for a description of event bindings.)

Note that this widget extends the behavior of its superclass vtkBorderRepresentation.

To create an instance of class vtkCaptionRepresentation, simply invoke its constructor as follows

  obj = vtkCaptionRepresentation
