Class VerticalLayout

java.lang.Object
  extended by org.apache.jorphan.gui.layout.VerticalLayout
All Implemented Interfaces:
LayoutManager, Serializable

public class VerticalLayout
extends Object
implements LayoutManager, Serializable

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 04 April 1999

Constructor Detail

VerticalLayout

public VerticalLayout()
Constructs an instance of VerticalLayout with a vertical vgap of 5 pixels, horizontal centering and anchored to the top of the display area.


VerticalLayout

public VerticalLayout(int vgap)
Constructs a VerticalLayout instance with horizontal centering, anchored to the top with the specified vgap.

Parameters:
vgap - an int value indicating the vertical seperation of the components

VerticalLayout

public VerticalLayout(int vgap,
                      int alignment)
Constructs a VerticalLayout instance anchored to the top with the specified vgap and horizontal alignment.

Parameters:
vgap - an int value indicating the vertical seperation of the components
alignment - an int value which is one of RIGHT, LEFT, CENTER, BOTH for the horizontal alignment.

VerticalLayout

public VerticalLayout(int vgap,
                      int alignment,
                      int anchor)
