vtkTextWidget

Section: Visualization Toolkit Widget Classes

Usage

This class provides support for interactively placing text on the 2D overlay plane. The text is defined by an instance of vtkTextActor. It uses the event bindings of its superclass (vtkBorderWidget). In addition, when the text is selected, the widget emits a WidgetActivateEvent that observers can watch for. This is useful for opening GUI dialogues to adjust font characteristics, etc. (Please see the superclass for a description of event bindings.)

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

  obj = vtkTextWidget
