Detailed Description

abstract class for representing widget handles

This class defines an API for widget handle representations. These representations interact with vtkHandleWidget. Various representations can be used depending on the nature of the handle. The basic functionality of the handle representation is to maintain a position. The position is represented via a vtkCoordinate, meaning that the position can be easily obtained in a variety of coordinate systems.

Optional features for this representation include an active mode (the widget appears only when the mouse pointer is close to it). The active distance is expressed in pixels and represents a circle in display space.

The class may be subclassed so that alternative representations can be created. The class defines an API and a default implementation that the vtkHandleWidget interacts with to render itself in the scene.

Warning
The separation of the widget event handling and representation enables users and developers to create new appearances for the widget. It also facilitates parallel processing, where the client application handles events, and remote representations of the widget are slaves to the client (and do not handle events).

◆ SetDisplayPosition()

virtual void vtkHandleRepresentation::SetDisplayPosition ( double  pos[3])
virtual

Handles usually have their coordinates set in display coordinates (generally by an associated widget) and internally maintain the position in world coordinates.

(Using world coordinates insures that handles are rendered in the right position when the camera view changes.) These methods are often subclassed because special constraint operations can be used to control the actual positioning.

Reimplemented in vtkAbstractPolygonalHandleRepresentation3D, vtkMeasurementCubeHandleRepresentation3D, vtkPointHandleRepresentation3D, vtkSphereHandleRepresentation, vtkConstrainedPointHandleRepresentation, and vtkPointHandleRepresentation2D.

◆ GetDisplayPosition() [1/2]

Handles usually have their coordinates set in display coordinates (generally by an associated widget) and internally maintain the position in world coordinates.

(Using world coordinates insures that handles are rendered in the right position when the camera view changes.) These methods are often subclassed because special constraint operations can be used to control the actual positioning.

◆ GetDisplayPosition() [2/2]

◆ SetTolerance()

virtual void vtkHandleRepresentation::SetTolerance ( int  )
virtual

The tolerance representing the distance to the widget (in pixels) in which the cursor is considered near enough to the widget to be active.

◆ GetTolerance()

virtual int vtkHandleRepresentation::GetTolerance ( )
virtual

The tolerance representing the distance to the widget (in pixels) in which the cursor is considered near enough to the widget to be active.

◆ SetActiveRepresentation()

virtual void vtkHandleRepresentation::SetActiveRepresentation ( vtkTypeBool  )
virtual

Flag controls whether the widget becomes visible when the mouse pointer moves close to it (i.e., the widget becomes active).

By default, ActiveRepresentation is off and the representation is always visible.

◆ GetActiveRepresentation()

virtual vtkTypeBool vtkHandleRepresentation::GetActiveRepresentation ( )
virtual

Flag controls whether the widget becomes visible when the mouse pointer moves close to it (i.e., the widget becomes active).

By default, ActiveRepresentation is off and the representation is always visible.

◆ ActiveRepresentationOn()

virtual void vtkHandleRepresentation::ActiveRepresentationOn ( )
virtual

Flag controls whether the widget becomes visible when the mouse pointer moves close to it (i.e., the widget becomes active).

By default, ActiveRepresentation is off and the representation is always visible.

◆ ActiveRepresentationOff()

virtual void vtkHandleRepresentation::ActiveRepresentationOff ( )
virtual

Flag controls whether the widget becomes visible when the mouse pointer moves close to it (i.e., the widget becomes active).

By default, ActiveRepresentation is off and the representation is always visible.

◆ SetInteractionState()

virtual void vtkHandleRepresentation::SetInteractionState ( int  )
virtual

The interaction state may be set from a widget (e.g., HandleWidget) or other object.

This controls how the interaction with the widget proceeds. Normally this method is used as part of a handshaking processwith the widget: First ComputeInteractionState() is invoked that returns a state based on geometric considerations (i.e., cursor near a widget feature), then based on events, the widget may modify this further.

◆ SetConstrained()

virtual void vtkHandleRepresentation::SetConstrained ( vtkTypeBool  )
virtual

Specify whether any motions (such as scale, translate, etc.) are constrained in some way (along an axis, etc.) Widgets can use this to control the resulting motion.

◆ GetConstrained()

virtual vtkTypeBool vtkHandleRepresentation::GetConstrained ( )
virtual

Specify whether any motions (such as scale, translate, etc.) are constrained in some way (along an axis, etc.) Widgets can use this to control the resulting motion.

◆ ConstrainedOn()

virtual void vtkHandleRepresentation::ConstrainedOn ( )
virtual

◆ ConstrainedOff()

virtual void vtkHandleRepresentation::ConstrainedOff ( )
virtual

Specify whether any motions (such as scale, translate, etc.) are constrained in some way (along an axis, etc.) Widgets can use this to control the resulting motion.

◆ CheckConstraint()

virtual int vtkHandleRepresentation::CheckConstraint ( vtkRenderer renderer,
double  pos[2] 
)
virtual

Method has to be overridden in the subclasses which has constraints on placing the handle (Ex.

vtkConstrainedPointHandleRepresentation). It should return 1 if the position is within the constraint, else it should return 0. By default it returns 1.

Reimplemented in vtkConstrainedPointHandleRepresentation.

◆ GetMTime()

vtkMTimeType vtkHandleRepresentation::GetMTime ( )

Reimplemented from vtkObject.

◆ SetPointPlacer()

virtual void vtkHandleRepresentation::SetPointPlacer ( vtkPointPlacer )
virtual

Point placers can be used to dictate constraints on the placement of handles. As an example, see vtkBoundedPlanePointPlacer (constrains the placement of handles to a set of bounded planes) vtkFocalPlanePointPlacer (constrains placement on the focal plane) etc. The default point placer is vtkPointPlacer (which does not apply any constraints, so the handles are free to move anywhere).
