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).

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.
