// .NAME vtkTextWidget - widget for placing text on overlay plane
// .SECTION Description
// 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.)

// Specify an instance of vtkWidgetRepresentation used to represent this

// so it can be added to the renderer independent of the widget.
void SetRepresentation(vtkTextRepresentation *r)

// Description:
// Specify a vtkTextActor to manage. This is a convenient, alternative
// method to specify the representation for the widget (i.e., used instead
// of SetRepresentation()). It internally creates a vtkTextRepresentation
// and then invokes vtkTextRepresentation::SetTextActor().

// Create the default widget representation if one is not set.
