Reimplemented from vtkAbstractContextItem.

void vtkControlPointsItem::SelectPoint ( vtkIdType  pointId)

Select a point by its ID

void vtkControlPointsItem::SelectPoint ( double *  currentPoint)

Utility function that selects a point providing its coordinates. To be found, the position of the point must be no further away than its painted point size

void vtkControlPointsItem::SelectAllPoints ( )

Select all the points

void vtkControlPointsItem::DeselectPoint ( vtkIdType  pointId)

Unselect a point by its ID

void vtkControlPointsItem::DeselectPoint ( double *  currentPoint)

Utility function that unselects a point providing its coordinates. To be found, the position of the point must be no further away than its painted point size

void vtkControlPointsItem::DeselectAllPoints ( )

Unselect all the previously selected points

void vtkControlPointsItem::ToggleSelectPoint ( vtkIdType  pointId)

Toggle the selection of a point by its ID. If the point was selected then unselect it, otherwise select it.

void vtkControlPointsItem::ToggleSelectPoint ( double *  currentPoint)

Utility function that toggles the selection a point providing its coordinates. To be found, the position of the point must be no further away than its painted point size

virtual bool vtkControlPointsItem::SelectPoints ( const vtkVector2f &  min,
const vtkVector2f &  max 
)
virtual

Select all points in the specified rectangle.

Reimplemented from vtkPlot.

vtkIdType vtkControlPointsItem::GetNumberOfSelectedPoints ( ) const

Return the number of selected points.

vtkIdType vtkControlPointsItem::FindPoint ( double *  pos)

Returns the vtkIdType of the point given its coordinates and a tolerance based on the screen point size.

bool vtkControlPointsItem::IsOverPoint ( double *  pos,
vtkIdType  pointId 
)

Returns true if pos is above the pointId point, false otherwise. It uses the size of the drawn point. To search what point is under the pos, use the more efficient

See also
FindPoint() instead.
vtkIdType vtkControlPointsItem::GetControlPointId ( double *  pos)

Returns the id of the control point exactly matching pos, -1 if not found.

void vtkControlPointsItem::GetControlPointsIds ( vtkIdTypeArray *  ids,
