virtual void SetPiecewiseFunction(vtkPiecewiseFunction *piecewiseFunc)
Set the PieceWiseFunction the handles will manipulate.

Set the parent item, which should be a vtkControlPointItem.
virtual bool Hit(const vtkContextMouseEvent &mouse)
Returns true if the supplied x, y coordinate is inside the item.
