static int vtkPiecewiseControlPointsItem::IsTypeOf ( const char * type )

static

virtual int vtkPiecewiseControlPointsItem::IsA ( const char * name )

virtual

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.

static vtkPiecewiseControlPointsItem* vtkPiecewiseControlPointsItem::SafeDownCast ( vtkObjectBase * o )

static

virtual vtkObjectBase* vtkPiecewiseControlPointsItem::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkControlPointsItem.

vtkPiecewiseControlPointsItem* vtkPiecewiseControlPointsItem::NewInstance ( ) const

virtual void vtkPiecewiseControlPointsItem::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

virtual

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

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.

virtual void vtkPiecewiseControlPointsItem::SetControlPoint	(	vtkIdType	index,
		double *	point
	)

protectedvirtual

Sets the x and y coordinates as well as the midpoint and sharpness of the control point corresponding to the index.

Implements vtkControlPointsItem.
