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.

Member Function Documentation

◆ New()

static vtkCaptionWidget* vtkCaptionWidget::New ( )

static

Instantiate this class.

◆ IsTypeOf()

static int vtkCaptionWidget::IsTypeOf ( const char * type )

static

◆ IsA()

virtual int vtkCaptionWidget::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkBorderWidget.

◆ SafeDownCast()

static vtkCaptionWidget* vtkCaptionWidget::SafeDownCast ( vtkObjectBase * o )

static

◆ NewInstanceInternal()

virtual vtkObjectBase* vtkCaptionWidget::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkBorderWidget.

◆ NewInstance()

vtkCaptionWidget* vtkCaptionWidget::NewInstance ( ) const

◆ PrintSelf()

void vtkCaptionWidget::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkBorderWidget.

◆ SetEnabled()

virtual void vtkCaptionWidget::SetEnabled ( int enabling )

virtual

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

Reimplemented from vtkAbstractWidget.

◆ SetRepresentation()

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.

◆ SetCaptionActor2D()

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().

◆ GetCaptionActor2D()

vtkCaptionActor2D* vtkCaptionWidget::GetCaptionActor2D ( )

◆ CreateDefaultRepresentation()

void vtkCaptionWidget::CreateDefaultRepresentation ( )

virtual

Create the default widget representation if one is not set.

Reimplemented from vtkBorderWidget.

◆ StartAnchorInteraction()

void vtkCaptionWidget::StartAnchorInteraction ( )

protected

◆ AnchorInteraction()

void vtkCaptionWidget::AnchorInteraction ( )

protected

◆ EndAnchorInteraction()

void vtkCaptionWidget::EndAnchorInteraction ( )

protected
