Public Member Functions
	vtkCheckerboardWidget (IntPtr rawCppThis, bool callDisposalMethod, bool strong)
	Automatically generated constructor - called from generated code. DO NOT call directly.
	vtkCheckerboardWidget ()
	Instantiate this class.
override void	CreateDefaultRepresentation ()
	Create the default widget representation if one is not set.
vtkCheckerboardRepresentation	GetCheckerboardRepresentation ()
	Return the representation as a vtkCheckerboardRepresentation.
override int	IsA (string type)
	Standard methods for a VTK class.
new vtkCheckerboardWidget	NewInstance ()
	Standard methods for a VTK class.
override void	SetEnabled (int arg0)
	The method for activiating and deactiviating this widget. This method must be overridden because it is a composite widget and does more than its superclasses' vtkAbstractWidget::SetEnabled() method.
void	SetRepresentation (vtkCheckerboardRepresentation r)
	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.
Public Member Functions inherited from Kitware.VTK.vtkAbstractWidget
	vtkAbstractWidget (IntPtr rawCppThis, bool callDisposalMethod, bool strong)
	Automatically generated constructor - called from generated code. DO NOT call directly.
vtkWidgetEventTranslator	GetEventTranslator ()
	Get the event translator. Careful manipulation of this class enables the user to override the default event bindings.
virtual int	GetManagesCursor ()
	Turn on or off the management of the cursor. Cursor management is typically disabled for subclasses when composite widgets are created. For example, vtkHandleWidgets are often used to create composite widgets, and the parent widget takes over the cursor management.
virtual vtkAbstractWidget	GetParent ()
	Specifying a parent to this widget is used when creating composite widgets. It is an internal method not meant to be used by the public. When a widget has a parent, it defers the rendering to the parent. It may also defer managing the cursor (see ManagesCursor ivar).
virtual int	GetProcessEvents ()
	Methods to change the whether the widget responds to interaction. Set this to Off to disable interaction. On by default. Subclasses must overide SetProcessEvents() to make sure that they pass on the flag to all component widgets.
virtual int	GetProcessEventsMaxValue ()
	Methods to change the whether the widget responds to interaction. Set this to Off to disable interaction. On by default. Subclasses must overide SetProcessEvents() to make sure that they pass on the flag to all component widgets.
virtual int	GetProcessEventsMinValue ()
	Methods to change the whether the widget responds to interaction. Set this to Off to disable interaction. On by default. Subclasses must overide SetProcessEvents() to make sure that they pass on the flag to all component widgets.
vtkWidgetRepresentation	GetRepresentation ()
	Return an instance of vtkWidgetRepresentation used to represent this widget in the scene. Note that the representation is a subclass of vtkProp (typically a subclass of vtkWidgetRepresenation) so it can be added to the renderer independent of the widget.
virtual void	ManagesCursorOff ()
	Turn on or off the management of the cursor. Cursor management is typically disabled for subclasses when composite widgets are created. For example, vtkHandleWidgets are often used to create composite widgets, and the parent widget takes over the cursor management.
virtual void	ManagesCursorOn ()
	Turn on or off the management of the cursor. Cursor management is typically disabled for subclasses when composite widgets are created. For example, vtkHandleWidgets are often used to create composite widgets, and the parent widget takes over the cursor management.
virtual void	ProcessEventsOff ()
	Methods to change the whether the widget responds to interaction. Set this to Off to disable interaction. On by default. Subclasses must overide SetProcessEvents() to make sure that they pass on the flag to all component widgets.
virtual void	ProcessEventsOn ()
	Methods to change the whether the widget responds to interaction. Set this to Off to disable interaction. On by default. Subclasses must overide SetProcessEvents() to make sure that they pass on the flag to all component widgets.
void	Render ()
	This method is called by subclasses when a render method is to be invoked on the vtkRenderWindowInteractor. This method should be called (instead of vtkRenderWindow::Render() because it has built into it optimizations for minimizing renders and/or speeding renders.
virtual void	SetManagesCursor (int _arg)
	Turn on or off the management of the cursor. Cursor management is typically disabled for subclasses when composite widgets are created. For example, vtkHandleWidgets are often used to create composite widgets, and the parent widget takes over the cursor management.
void	SetParent (vtkAbstractWidget parent)
	Specifying a parent to this widget is used when creating composite widgets. It is an internal method not meant to be used by the public. When a widget has a parent, it defers the rendering to the parent. It may also defer managing the cursor (see ManagesCursor ivar).
override void	SetPriority (float arg0)
	Override the superclass method. This will automatically change the priority of the widget. Unlike the superclass documentation, no methods such as SetInteractor to null and reset it etc. are necessary.
virtual void	SetProcessEvents (int _arg)
	Methods to change the whether the widget responds to interaction. Set this to Off to disable interaction. On by default. Subclasses must overide SetProcessEvents() to make sure that they pass on the flag to all component widgets.
Public Member Functions inherited from Kitware.VTK.vtkInteractorObserver
	vtkInteractorObserver (IntPtr rawCppThis, bool callDisposalMethod, bool strong)
	Automatically generated constructor - called from generated code. DO NOT call directly.
void	EnabledOff ()
	Methods for turning the interactor observer on and off, and determining its state. All subclasses must provide the SetEnabled() method. Enabling a vtkInteractorObserver has the side effect of adding observers; disabling it removes the observers. Prior to enabling the vtkInteractorObserver you must set the render window interactor (via SetInteractor()). Initial value is 0.
void	EnabledOn ()
	Methods for turning the interactor observer on and off, and determining its state. All subclasses must provide the SetEnabled() method. Enabling a vtkInteractorObserver has the side effect of adding observers; disabling it removes the observers. Prior to enabling the vtkInteractorObserver you must set the render window interactor (via SetInteractor()). Initial value is 0.
virtual vtkRenderer	GetCurrentRenderer ()
	Set/Get the current renderer. Normally when the widget is activated (SetEnabled(1) or when keypress activation takes place), the renderer over which the mouse pointer is positioned is used and assigned to this Ivar. Alternatively, you might want to set the CurrentRenderer explicitly. WARNING: note that if the DefaultRenderer Ivar is set (see above), it will always override the parameter passed to SetCurrentRenderer, unless it is NULL. (i.e., SetCurrentRenderer(foo) = SetCurrentRenderer(DefaultRenderer).
virtual vtkRenderer	GetDefaultRenderer ()
	Set/Get the default renderer to use when activating the interactor observer. Normally when the widget is activated (SetEnabled(1) or when keypress activation takes place), the renderer over which the mouse pointer is positioned is used. Alternatively, you can specify the renderer to bind the interactor to when the interactor observer is activated.
int	GetEnabled ()
	Methods for turning the interactor observer on and off, and determining its state. All subclasses must provide the SetEnabled() method. Enabling a vtkInteractorObserver has the side effect of adding observers; disabling it removes the observers. Prior to enabling the vtkInteractorObserver you must set the render window interactor (via SetInteractor()). Initial value is 0.
virtual vtkRenderWindowInteractor	GetInteractor ()
	This method is used to associate the widget with the render window interactor. Observers of the appropriate events invoked in the render window interactor are set up as a result of this method invocation. The SetInteractor() method must be invoked prior to enabling the vtkInteractorObserver.
virtual int	GetKeyPressActivation ()
	Enable/Disable of the use of a keypress to turn on and off the interactor observer. (By default, the keypress is 'i' for "interactor observer".) Set the KeyPressActivationValue to change which key activates the widget.)
virtual sbyte	GetKeyPressActivationValue ()
	Specify which key press value to use to activate the interactor observer (if key press activation is enabled). By default, the key press activation value is 'i'. Note: once the SetInteractor() method is invoked, changing the key press activation value will not affect the key press until SetInteractor(NULL)/SetInteractor(iren) is called.
virtual float	GetPriority ()
	Set/Get the priority at which events are processed. This is used when multiple interactor observers are used simultaneously. The default value is 0.0 (lowest priority.) Note that when multiple interactor observer have the same priority, then the last observer added will process the event first. (Note: once the SetInteractor() method has been called, changing the priority does not effect event processing. You will have to SetInteractor(NULL), change priority, and then SetInteractor(iren) to have the priority take effect.)
virtual float	GetPriorityMaxValue ()
	Set/Get the priority at which events are processed. This is used when multiple interactor observers are used simultaneously. The default value is 0.0 (lowest priority.) Note that when multiple interactor observer have the same priority, then the last observer added will process the event first. (Note: once the SetInteractor() method has been called, changing the priority does not effect event processing. You will have to SetInteractor(NULL), change priority, and then SetInteractor(iren) to have the priority take effect.)
virtual float	GetPriorityMinValue ()
	Set/Get the priority at which events are processed. This is used when multiple interactor observers are used simultaneously. The default value is 0.0 (lowest priority.)

virtual void	KeyPressActivationOn ()
	Enable/Disable of the use of a keypress to turn on and off the interactor observer. (By default, the keypress is 'i' for "interactor observer".) Set the KeyPressActivationValue to change which key activates the widget.)
void	Off ()
	Methods for turning the interactor observer on and off, and determining its state. All subclasses must provide the SetEnabled() method. Enabling a vtkInteractorObserver has the side effect of adding observers; disabling it removes the observers. Prior to enabling the vtkInteractorObserver you must set the render window interactor (via SetInteractor()). Initial value is 0.

Normally when the widget is activated (SetEnabled(1) or when keypress activation takes place), the renderer over which the mouse pointer is positioned is used. Alternatively, you can specify the renderer to bind the interactor to when the interactor observer is activated.
virtual void	SetInteractor (vtkRenderWindowInteractor iren)

Detailed Description

vtkCheckerboardWidget - interactively set the number of divisions in 2D image checkerboard

Description 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: <pre> 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; </pre> 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.
