	)

virtual

Reimplemented from vtkControlPointsItem.

static vtkPiecewiseControlPointsItem* vtkPiecewiseControlPointsItem::New ( )

static

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
	)		const

protectedvirtual

Returns the x and y coordinates as well as the midpoint and sharpness of the control point corresponding to the index. point must be a double array of size 4.

Implements vtkControlPointsItem.
