Package PamView.panel

Class VerticalLayout

java.lang.Object
PamView.panel.VerticalLayout
All Implemented Interfaces:
LayoutManager
public class VerticalLayout extends Object implements LayoutManager
A vertical layout manager similar to java.awt.FlowLayout. Like FlowLayout components do not expand to fill available space except when the horizontal alignment is BOTH in which case components are stretched horizontally. Unlike FlowLayout, components will not wrap to form another column if there isn't enough space vertically. VerticalLayout can optionally anchor components to the top or bottom of the display area or center them between the top and bottom. Revision date 12th July 2001
