public class BorderLayout
extends Layout

A border layout lays out a container, arranging and resizing its components to fit in five regions: north, south, east, west, and center. Each region may contain no more than one component, and is identified by a corresponding constant: NORTH, SOUTH, EAST, WEST, and CENTER. When adding a component to a container with a border layout, use one of these five constants.

Field Summary

static String	CENTER The center layout constraint (middle of container).
static String	EAST The east layout constraint (right of container).
static String	NORTH The north layout constraint (top of container).
static String	SOUTH The south layout constraint (bottom of container).
static String	WEST The west layout constraint (left of container).

Constructor Summary

BorderLayout()
Creates a new instance of BorderLayout.

Method Summary

void	addLayoutComponent(Object name, Component comp, Container c) Some layouts can optionally track the addition of elements with meta-data that allows the user to "hint" on object positioning.
Object	getComponentConstraint(Component comp) Returns the component's constraint.
Dimension	getPreferredSize(Container parent) Returns the container preferred size.
void	layoutContainer(Container target) Layout the given parent container children.
void	removeLayoutComponent(Component comp) Removes the component from the layout this operation is only useful if the layout maintains references to components within it.
