Detailed Description

abstract PolyDataSource-based 3D widget

This abstract class serves as parent to 3D widgets that have simple vtkPolyDataSource instances defining their geometry.

In addition to what is offered by the vtk3DWidget parent, this class makes it possible to manipulate the underlying polydatasource and to PlaceWidget() according to that, instead of having to make use of SetInput() or SetProp3D().

Implementors of child classes HAVE to implement their PlaceWidget(bounds) to check for the existence of Input and Prop3D FIRST. If these don't exist, place according to the underlying PolyDataSource. Child classes also have to imprement UpdatePlacement(), which updates the widget according to the geometry of the underlying PolyDataSource.

typedef vtk3DWidget vtkPolyDataSourceWidget::Superclass

Definition at line 48 of file vtkPolyDataSourceWidget.h.

Constructor & Destructor Documentation

◆ vtkPolyDataSourceWidget()

vtkPolyDataSourceWidget::vtkPolyDataSourceWidget ( )

protected

Empty constructor that calls the parent constructor.

Child classes should call this constructor as part of their initialisation.

Member Function Documentation

◆ IsTypeOf()

static vtkTypeBool vtkPolyDataSourceWidget::IsTypeOf ( const char * type )

static

◆ IsA()

virtual vtkTypeBool vtkPolyDataSourceWidget::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 vtk3DWidget.

Reimplemented in vtkImagePlaneWidget, vtkImplicitPlaneWidget, and vtkPlaneWidget.

◆ SafeDownCast()

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

static

◆ NewInstanceInternal()

virtual vtkObjectBase * vtkPolyDataSourceWidget::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtk3DWidget.

Reimplemented in vtkImagePlaneWidget, vtkImplicitPlaneWidget, and vtkPlaneWidget.

◆ NewInstance()

vtkPolyDataSourceWidget * vtkPolyDataSourceWidget::NewInstance ( ) const

◆ PrintSelf()

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

overridevirtual

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 vtk3DWidget.

◆ PlaceWidget() [1/3]

void vtkPolyDataSourceWidget::PlaceWidget ( )

overridevirtual

Overrides vtk3DWidget PlaceWidget() so that it doesn't complain if there's no Input and no Prop3D.

Reimplemented from vtk3DWidget.

◆ PlaceWidget() [2/3]

void vtkPolyDataSourceWidget::PlaceWidget ( double bounds[6] )

overridepure virtual

We have to redeclare this abstract, PlaceWidget() requires it.

You HAVE to override this in your concrete child classes. If there's no Prop3D and no Input, your PlaceWidget must make use of the underlying PolyDataSource to do its work.

Implements vtk3DWidget.

Implemented in vtkImagePlaneWidget, vtkImplicitPlaneWidget, and vtkPlaneWidget.

◆ PlaceWidget() [3/3]

void vtkPolyDataSourceWidget::PlaceWidget	(	double	xmin,
		double	xmax,
		double	ymin,
		double	ymax,
		double	zmin,
		double	zmax
	)

inlineoverridevirtual

Convenience method brought over from vtkPlaneWidget.

Reimplemented from vtk3DWidget.

Definition at line 68 of file vtkPolyDataSourceWidget.h.

◆ GetPolyDataAlgorithm()

virtual vtkPolyDataAlgorithm * vtkPolyDataSourceWidget::GetPolyDataAlgorithm ( )

pure virtual

Returns underlying vtkPolyDataAlgorithm that determines geometry.

This can be modified after which PlaceWidget() or UpdatePlacement() can be called. UpdatePlacement() will always update the planewidget according to the geometry of the underlying PolyDataAlgorithm. PlaceWidget() will only make use of this geometry if there is no Input and no Prop3D set.

Implemented in vtkImagePlaneWidget, vtkImplicitPlaneWidget, and vtkPlaneWidget.

◆ UpdatePlacement()

virtual void vtkPolyDataSourceWidget::UpdatePlacement ( )

pure virtual

If you've made changes to the underlying vtkPolyDataSource AFTER your initial call to PlaceWidget(), use this method to realise the changes in the widget.

Implemented in vtkImplicitPlaneWidget, vtkImagePlaneWidget, and vtkPlaneWidget.
