public class RigidBoxGroup

Parameters:

v - the DocumentView that does the actual drawing.

Overrides:

doLayout in class AbstractBox

Following copied from interface: Box

Parameters:

g - the graphics context. Some boxes, like TextFragments, need a graphics context before they can determine their width and height.

c - the component into which the box will be drawn. An ImageBox needs to know the component to calculate the width and height.

w - the width available for to the Box.
