vtkScalarBarWidget

Section: Visualization Toolkit Widget Classes

Usage

This class provides support for interactively manipulating the position, size, and orientation of a scalar bar. It listens to Left mouse events and mouse movement. It also listens to Right mouse events and notifies any observers of Right mouse events on this object when they occur. It will change the cursor shape based on its location. If the cursor is over an edge of the scalar bar it will change the cursor shape to a resize edge shape. If the position of a scalar bar is moved to be close to the center of one of the four edges of the viewport, then the scalar bar will change its orientation to align with that edge. This orientation is sticky in that it will stay that orientation until the position is moved close to another edge.

To create an instance of class vtkScalarBarWidget, simply invoke its constructor as follows
