* @class vtkTextWidget
|

|
|
* @brief widget for placing text on overlay plane
|
||
|
|
*
|
||
|
|
* 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.)
