Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkControlPointsItem.

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

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.

vtkIdType vtkPiecewiseControlPointsItem::AddPoint ( double newPos)
overridevirtual

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.

vtkIdType vtkPiecewiseControlPointsItem::RemovePoint ( double pos)
overridevirtual

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.

Must be reimplemented by subclasses to calculate the points to draw.

It's subclass responsibility to call ComputePoints() via the callback

Implements vtkControlPointsItem.
