Detailed Description

provide the representation for a vtkSliderWidget with a 3D skin

This class is used to represent and render a vtkSliderWidget. To use this class, you must at a minimum specify the end points of the slider. Optional instance variable can be used to modify the appearance of the widget.

Member Function Documentation

◆ New()

static vtkSliderRepresentation3D* vtkSliderRepresentation3D::New ( )

static

Instantiate the class.

◆ IsTypeOf()

static int vtkSliderRepresentation3D::IsTypeOf ( const char * type )

static

◆ IsA()

virtual int vtkSliderRepresentation3D::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 vtkSliderRepresentation.

◆ SafeDownCast()

static vtkSliderRepresentation3D* vtkSliderRepresentation3D::SafeDownCast ( vtkObjectBase * o )

static

◆ NewInstanceInternal()

virtual vtkObjectBase* vtkSliderRepresentation3D::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkSliderRepresentation.

◆ NewInstance()

vtkSliderRepresentation3D* vtkSliderRepresentation3D::NewInstance ( ) const

◆ PrintSelf()

void vtkSliderRepresentation3D::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 vtkSliderRepresentation.

◆ GetPoint1Coordinate()

vtkCoordinate* vtkSliderRepresentation3D::GetPoint1Coordinate ( )

Position the first end point of the slider. Note that this point is an instance of vtkCoordinate, meaning that Point 1 can be specified in a variety of coordinate systems, and can even be relative to another point. To set the point, you'll want to get the Point1Coordinate and then invoke the necessary methods to put it into the correct coordinate system and set the correct initial value.

◆ SetPoint1InWorldCoordinates()

void vtkSliderRepresentation3D::SetPoint1InWorldCoordinates	(	double	x,
		double	y,
		double	z
	)

◆ GetPoint2Coordinate()

vtkCoordinate* vtkSliderRepresentation3D::GetPoint2Coordinate ( )

Position the second end point of the slider. Note that this point is an instance of vtkCoordinate, meaning that Point 1 can be specified in a variety of coordinate systems, and can even be relative to another point. To set the point, you'll want to get the Point2Coordinate and then invoke the necessary methods to put it into the correct coordinate system and set the correct initial value.

◆ SetPoint2InWorldCoordinates()

void vtkSliderRepresentation3D::SetPoint2InWorldCoordinates	(	double	x,
		double	y,
		double	z
	)

◆ SetTitleText()

virtual void vtkSliderRepresentation3D::SetTitleText ( const char * )

virtual

Specify the title text for this widget. If the value is not set, or set to the empty string "", then the title text is not displayed.

Reimplemented from vtkSliderRepresentation.

◆ GetTitleText()

virtual const char* vtkSliderRepresentation3D::GetTitleText ( )

virtual

Reimplemented from vtkSliderRepresentation.

◆ SetSliderShape()

virtual void vtkSliderRepresentation3D::SetSliderShape ( int )

virtual

Specify whether to use a sphere or cylinder slider shape. By default, a sphere shape is used.

◆ GetSliderShape()

virtual int vtkSliderRepresentation3D::GetSliderShape ( )

virtual

◆ SetSliderShapeToSphere()

void vtkSliderRepresentation3D::SetSliderShapeToSphere ( )

inline

Definition at line 100 of file vtkSliderRepresentation3D.h.

◆ SetSliderShapeToCylinder()

void vtkSliderRepresentation3D::SetSliderShapeToCylinder ( )

inline

Definition at line 101 of file vtkSliderRepresentation3D.h.

◆ SetRotation()

virtual void vtkSliderRepresentation3D::SetRotation ( double )

virtual

Set the rotation of the slider widget around the axis of the widget. This is used to control which way the widget is initially oriented. (This is especially important for the label and title.)

◆ GetRotation()

virtual double vtkSliderRepresentation3D::GetRotation ( )

virtual

◆ GetSliderProperty()

virtual vtkProperty* vtkSliderRepresentation3D::GetSliderProperty ( )

virtual

Get the slider properties. The properties of the slider when selected and unselected can be manipulated.

◆ GetTubeProperty()

virtual vtkProperty* vtkSliderRepresentation3D::GetTubeProperty ( )

virtual

Get the properties for the tube and end caps.

◆ GetCapProperty()

virtual vtkProperty* vtkSliderRepresentation3D::GetCapProperty ( )

virtual

◆ GetSelectedProperty()

virtual vtkProperty* vtkSliderRepresentation3D::GetSelectedProperty ( )

virtual

Get the selection property. This property is used to modify the appearance of selected objects (e.g., the slider).

◆ PlaceWidget()

virtual void vtkSliderRepresentation3D::PlaceWidget ( double bounds[6] )

virtual

Methods to interface with the vtkSliderWidget.

◆ BuildRepresentation()

virtual void vtkSliderRepresentation3D::BuildRepresentation ( )

virtual

Implements vtkWidgetRepresentation.

◆ StartWidgetInteraction()

virtual void vtkSliderRepresentation3D::StartWidgetInteraction ( double eventPos[2] )

virtual

Reimplemented from vtkWidgetRepresentation.

◆ WidgetInteraction()

virtual void vtkSliderRepresentation3D::WidgetInteraction ( double newEventPos[2] )

virtual

Reimplemented from vtkWidgetRepresentation.

◆ Highlight()

virtual void vtkSliderRepresentation3D::Highlight ( int )

virtual

◆ GetBounds()

virtual double* vtkSliderRepresentation3D::GetBounds ( )

virtual

Methods supporting the rendering process.

Reimplemented from vtkWidgetRepresentation.

◆ GetActors()

virtual void vtkSliderRepresentation3D::GetActors ( vtkPropCollection * )

virtual

For some exporters and other other operations we must be able to collect all the actors or volumes. These methods are used in that process.

Reimplemented from vtkWidgetRepresentation.

◆ ReleaseGraphicsResources()

virtual void vtkSliderRepresentation3D::ReleaseGraphicsResources ( vtkWindow * )

virtual

WARNING: INTERNAL METHOD - NOT INTENDED FOR GENERAL USE Release any graphics resources that are being consumed by this actor. The parameter window could be used to determine which graphic resources to release.

Reimplemented from vtkWidgetRepresentation.

◆ RenderOpaqueGeometry()

virtual int vtkSliderRepresentation3D::RenderOpaqueGeometry ( vtkViewport * )

virtual

WARNING: INTERNAL METHOD - NOT INTENDED FOR GENERAL USE DO NOT USE THESE METHODS OUTSIDE OF THE RENDERING PROCESS All concrete subclasses must be able to render themselves. There are four key render methods in vtk and they correspond to four different points in the rendering cycle. Any given prop may implement one or more of these methods. The first method is intended for rendering all opaque geometry. The second method is intended for rendering all translucent polygonal geometry. The third one is intended for rendering all translucent volumetric geometry. Most of the volume rendering mappers draw their results during this third method. The last method is to render any 2D annotation or overlays. Each of these methods return an integer value indicating whether or not this render method was applied to this data.

Reimplemented from vtkProp.

◆ RenderTranslucentPolygonalGeometry()

virtual int vtkSliderRepresentation3D::RenderTranslucentPolygonalGeometry ( vtkViewport * )

virtual

Reimplemented from vtkProp.

◆ HasTranslucentPolygonalGeometry()

virtual int vtkSliderRepresentation3D::HasTranslucentPolygonalGeometry ( )

virtual

WARNING: INTERNAL METHOD - NOT INTENDED FOR GENERAL USE DO NOT USE THESE METHODS OUTSIDE OF THE RENDERING PROCESS Does this prop have some translucent polygonal geometry? This method is called during the rendering process to know if there is some translucent polygonal geometry. A simple prop that has some translucent polygonal geometry will return true. A composite prop (like vtkAssembly) that has at least one sub-prop that has some translucent polygonal geometry will return true. Default implementation return false.
