Detailed Description

interactively set the number of divisions in 2D image checkerboard

The vtkCheckerboardWidget is used to interactively control an instance of vtkImageCheckerboard (and an associated vtkImageActor used to display the checkerboard). The user can adjust the number of divisions in each of the i-j directions in a 2D image. A frame appears around the vtkImageActor with sliders along each side of the frame. The user can interactively adjust the sliders to the desired number of checkerboard subdivisions.

To use this widget, specify an instance of vtkImageCheckerboard and an instance of vtkImageActor. By default, the widget responds to the following events:

 If the slider bead is selected:
   LeftButtonPressEvent - select slider (if on slider)
   LeftButtonReleaseEvent - release slider
   MouseMoveEvent - move slider
 If the end caps or slider tube of a slider are selected:
   LeftButtonPressEvent - jump (or animate) to cap or point on tube;

It is possible to change these event bindings. Please refer to the documentation for vtkSliderWidget for more information. Advanced users may directly access and manipulate the sliders by obtaining the instances of vtkSliderWidget composing the vtkCheckerboard widget.

void vtkCheckerboardWidget::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		`[virtual]`

Standard methods for a VTK class.

Reimplemented from vtkAbstractWidget.

virtual void vtkCheckerboardWidget::SetEnabled ( int ) [virtual]

The method for activating and deactivating this widget. This method must be overridden because it is a composite widget and does more than its superclasses' vtkAbstractWidget::SetEnabled() method.

Reimplemented from vtkAbstractWidget.

void vtkCheckerboardWidget::SetRepresentation ( vtkCheckerboardRepresentation * 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 82 of file vtkCheckerboardWidget.h.

vtkCheckerboardRepresentation* vtkCheckerboardWidget::GetCheckerboardRepresentation ( ) [inline]

Return the representation as a vtkCheckerboardRepresentation.

Definition at line 88 of file vtkCheckerboardWidget.h.

void vtkCheckerboardWidget::CreateDefaultRepresentation ( ) [virtual]

Create the default widget representation if one is not set.

Implements vtkAbstractWidget.
