Detailed Description

a class defining the representation for a vtkLineWidget2

This class is a concrete representation for the vtkLineWidget2. It represents a straight line with three handles: one at the beginning and ending of the line, and one used to translate the line. Through interaction with the widget, the line representation can be arbitrarily placed in the 3D space.

To use this representation, you normally specify the position of the two end points (either in world or display coordinates). The PlaceWidget() method is also used to initially position the representation.

Warning: This class, and vtkLineWidget2, are next generation VTK widgets. An earlier version of this functionality was defined in the class vtkLineWidget.
