Creates a piecewise control points object

virtual void vtkPiecewiseControlPointsItem::SetPiecewiseFunction ( vtkPiecewiseFunction *  function)
virtual

Set the piecewise function to draw its points

virtual vtkPiecewiseFunction* vtkPiecewiseControlPointsItem::GetPiecewiseFunction ( )
virtual

Get the piecewise function

virtual vtkIdType vtkPiecewiseControlPointsItem::AddPoint ( double *  newPos)
virtual

Add a point to the function. Returns the index of the point (0 based), or -1 on error. Subclasses should reimplement this function to do the actual work.

Implements vtkControlPointsItem.

virtual vtkIdType vtkPiecewiseControlPointsItem::RemovePoint ( double *  pos)
virtual

Remove a point of the function. Returns the index of the point (0 based), or -1 on error. Subclasses should reimplement this function to do the actual work.

Implements vtkControlPointsItem.

virtual void vtkPiecewiseControlPointsItem::SetStrokeMode ( bool  )
virtual

Controls whether or not control points are drawn (true) or clicked and moved (false). False by default.

virtual void vtkPiecewiseControlPointsItem::emitEvent ( unsigned long  event,
void *  params = 0 
)
protectedvirtual

Implements vtkControlPointsItem.

virtual unsigned long int vtkPiecewiseControlPointsItem::GetControlPointsMTime ( )
protectedvirtual

Must be reimplemented by subclasses to calculate the points to draw. It's subclass responsibility to call ComputePoints() via the callback

Implements vtkControlPointsItem.

virtual vtkIdType vtkPiecewiseControlPointsItem::GetNumberOfPoints ( ) const
protectedvirtual

Returns the total number of points

Implements vtkControlPointsItem.

virtual void vtkPiecewiseControlPointsItem::GetControlPoint ( vtkIdType  index,
double *  point
