Detailed Description

widget for placing a caption (text plus leader)

This class provides support for interactively placing a caption on the 2D overlay plane. 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 represented by a vtkCaptionRepresentation. 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 vtkBorderWidget. The end point of the leader can be selected and moved around with an internal vtkHandleWidget.

virtual void vtkCaptionWidget::SetEnabled ( int  enabling)
virtual

Override superclasses' SetEnabled() method because the caption leader has its own dedicated widget.

Reimplemented from vtkAbstractWidget.

void vtkCaptionWidget::SetRepresentation ( vtkCaptionRepresentation r)
inline

Specify an instance of vtkWidgetRepresentation used to represent this widget in the scene. Note that the representation is a subclass of vtkProp so it can be added to the renderer independent of the widget.

Definition at line 76 of file vtkCaptionWidget.h.

void vtkCaptionWidget::SetCaptionActor2D ( vtkCaptionActor2D capActor)

Specify a vtkCaptionActor2D to manage. This is convenient, alternative method to SetRepresentation(). It internally create a vtkCaptionRepresentation and then invokes vtkCaptionRepresentation::SetCaptionActor2D().

vtkCaptionActor2D* vtkCaptionWidget::GetCaptionActor2D ( )

Specify a vtkCaptionActor2D to manage. This is convenient, alternative method to SetRepresentation(). It internally create a vtkCaptionRepresentation and then invokes vtkCaptionRepresentation::SetCaptionActor2D().

void vtkCaptionWidget::CreateDefaultRepresentation ( )
virtual

Create the default widget representation if one is not set.
