Detailed Description

represent the position of a point in display coordinates

This class is used to represent a vtkHandleWidget. It represents a position in 2D world coordinates using a x-y cursor (the cursor defined by an instance of vtkPolyData and generated by a vtkPolyDataAlgorithm).

SetCursorShape()

void vtkPointHandleRepresentation2D::SetCursorShape

(

vtkPolyData *

cursorShape

)

Specify the cursor shape with an instance of vtkPolyData.

Note that shape is assumed to be defined in the display coordinate system. By default a vtkCursor2D shape is used.

GetCursorShape()

vtkPolyData * vtkPointHandleRepresentation2D::GetCursorShape

(

)

Specify the cursor shape with an instance of vtkPolyData.

Note that shape is assumed to be defined in the display coordinate system. By default a vtkCursor2D shape is used.

SetDisplayPosition()

void vtkPointHandleRepresentation2D::SetDisplayPosition ( double  xyz[3] )

override

Set/Get the position of the point in display coordinates.

This overloads the superclasses SetDisplayPosition in order to set the focal point of the cursor.

SetProperty()

void vtkPointHandleRepresentation2D::SetProperty

(

vtkProperty2D *

)

Set/Get the handle properties when unselected and selected.

SetSelectedProperty()

void vtkPointHandleRepresentation2D::SetSelectedProperty

(

)

Set/Get the handle properties when unselected and selected.

GetProperty()

virtual vtkProperty2D * vtkPointHandleRepresentation2D::GetProperty ( )

virtual

Set/Get the handle properties when unselected and selected.

GetSelectedProperty()

virtual vtkProperty2D * vtkPointHandleRepresentation2D::GetSelectedProperty ( )

virtual

Set/Get the handle properties when unselected and selected.

GetBounds()

double * vtkPointHandleRepresentation2D::GetBounds ( )

overridevirtual

Subclasses of vtkPointHandleRepresentation2D must implement these methods.

These are the methods that the widget and its representation use to communicate with each other.

Reimplemented from vtkProp.

BuildRepresentation()

void vtkPointHandleRepresentation2D::BuildRepresentation ( )

overridevirtual

Subclasses of vtkPointHandleRepresentation2D must implement these methods.

These are the methods that the widget and its representation use to communicate with each other.

Implements vtkWidgetRepresentation.

StartWidgetInteraction()

Highlight()

void vtkPointHandleRepresentation2D::Highlight ( int  highlight )

override

SetPointPlacer()

void vtkPointHandleRepresentation2D::SetPointPlacer ( vtkPointPlacer *  )

overridevirtual

Override the superclass implementation.

This class does not use a point placer. Point placers dictate the placement of points in 3D space. Since this class constrains points to lie in an overlay plane anyway, we don't care. Just returns.

Reimplemented from vtkHandleRepresentation.

SetVisibility()

void vtkPointHandleRepresentation2D::SetVisibility ( vtkTypeBool  visible )

overridevirtual

Override to ensure that the internal actor's visibility is consistent with this representation's visibility.

Inconsistency between the two would cause issues in picking logic which relies on individual view prop visibility to determine whether the prop is pickable.

Reimplemented from vtkProp.

Translate() [1/3]

void vtkPointHandleRepresentation2D::Translate ( const double *  v )

overrideprotectedvirtual

Translates world position by vector v projected on the constraint axis if any.

Reimplemented from vtkHandleRepresentation.
