		int	modify = `0`
	)		`[virtual]`

Given (x, y) display coordinates in a renderer, with a possible flag that modifies the computation, determine the current state of the widget.

Reimplemented from vtkWidgetRepresentation.

unsigned int vtkTransferFunctionEditorRepresentationSimple1D::CreateHandle	(	double	displayPos[3],
		double	scalar
	)

Create a new handle representation for a transfer function node at a particular display position. Returns the id of the node.

double vtkTransferFunctionEditorRepresentationSimple1D::GetHandleScalar	(	unsigned int	idx,
		int &	valid
	)

Get the scalar value associated with the handle at the given index.

virtual unsigned int vtkTransferFunctionEditorRepresentationSimple1D::GetNumberOfHandles ( ) [virtual]

Return the number of existing handles.

Reimplemented from vtkTransferFunctionEditorRepresentation.

vtkHandleRepresentation* vtkTransferFunctionEditorRepresentationSimple1D::GetHandleRepresentation ( unsigned int idx )

Return the vtkHandleRepresentation (for a transfer function node) with a particular id. Returns NULL if the id is out of range.

virtual int vtkTransferFunctionEditorRepresentationSimple1D::SetHandleDisplayPosition	(	unsigned int	nodeNum,
		double	pos[3],
		double	scalar
	)		`[virtual]`

Set/get the display position of a vtkHandleRepresentation (for a transfer function node) with a particular id. When setting the position, a return value of 1 indicates the node was set to the position indicated. A return value of 0 indicates the nodes was not repositioned.

void vtkTransferFunctionEditorRepresentationSimple1D::GetHandleDisplayPosition	(	unsigned int	nodeNum,
		double	pos[3]
	)

Set/get the display position of a vtkHandleRepresentation (for a transfer function node) with a particular id. When setting the position, a return value of 1 indicates the node was set to the position indicated. A return value of 0 indicates the nodes was not repositioned.

double* vtkTransferFunctionEditorRepresentationSimple1D::GetHandleDisplayPosition ( unsigned int nodeNum )

Set/get the display position of a vtkHandleRepresentation (for a transfer function node) with a particular id. When setting the position, a return value of 1 indicates the node was set to the position indicated. A return value of 0 indicates the nodes was not repositioned.
