static

virtual int vtkCompositeControlPointsItem::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 vtkColorTransferControlPointsItem.

virtual void vtkCompositeControlPointsItem::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 vtkColorTransferControlPointsItem.

static vtkCompositeControlPointsItem* vtkCompositeControlPointsItem::New ( )

static

Creates a piecewise control points object.

virtual void vtkCompositeControlPointsItem::SetColorTransferFunction ( vtkColorTransferFunction * function )

virtual

Set the color transfer function to draw its points.

void vtkCompositeControlPointsItem::SetOpacityFunction ( vtkPiecewiseFunction * opacity )

Utility function that calls SetPiecewiseFunction()

virtual vtkPiecewiseFunction* vtkCompositeControlPointsItem::GetOpacityFunction ( )

virtual

Utility function that calls SetPiecewiseFunction()

virtual void vtkCompositeControlPointsItem::SetPointsFunction ( int )

virtual

PointsFunction controls wether the points represent the ColorTransferFunction, OpacityTransferFunction or both.

If ColorPointsFunction, only the points of the ColorTransfer function are used. If OpacityPointsFunction, only the points of the Opacity function are used If ColorAndOpacityPointsFunction, the points of both functions are shared by both functions. ColorAndOpacityPointsFunction by default. Note: Set the mode before the functions are set. ColorPointsFunction is not fully supported.

virtual int vtkCompositeControlPointsItem::GetPointsFunction ( )

virtual

PointsFunction controls wether the points represent the ColorTransferFunction, OpacityTransferFunction or both.

If ColorPointsFunction, only the points of the ColorTransfer function are used. If OpacityPointsFunction, only the points of the Opacity function are used If ColorAndOpacityPointsFunction, the points of both functions are shared by both functions. ColorAndOpacityPointsFunction by default. Note: Set the mode before the functions are set. ColorPointsFunction is not fully supported.

virtual vtkIdType vtkCompositeControlPointsItem::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.

Reimplemented from vtkColorTransferControlPointsItem.

virtual vtkIdType vtkCompositeControlPointsItem::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.

Reimplemented from vtkColorTransferControlPointsItem.

virtual void vtkCompositeControlPointsItem::SetUseOpacityPointHandles ( bool )

virtual

If UseOpacityPointHandles is true, when the current point is double clicked, a vtkPiecewisePointHandleItem will show up so that the sharpness and mid point can be adjusted in the scene with those handles False by default.

virtual bool vtkCompositeControlPointsItem::GetUseOpacityPointHandles ( )

virtual

If UseOpacityPointHandles is true, when the current point is double clicked, a vtkPiecewisePointHandleItem will show up so that the sharpness and mid point can be adjusted in the scene with those handles False by default.

virtual bool vtkCompositeControlPointsItem::MouseMoveEvent ( const vtkContextMouseEvent & mouse )

virtual

Mouse move event.

To take care of some special Key stroke

Reimplemented from vtkControlPointsItem.

virtual bool vtkCompositeControlPointsItem::MouseDoubleClickEvent ( const vtkContextMouseEvent & mouse )

virtual

Mouse move event.

To take care of some special Key stroke
