All Implemented Interfaces:

LayoutManager, LayoutManager2

public class BorderLayout

extends java.lang.Object

implements LayoutManager2

A concrete implementation of LayoutManager that lays out its components around its edges. The components are laid out according to their preferred sizes and the constraints of the container's size. The NORTH and SOUTH components may be stretched horizontally; the WEST and EAST components may be stretched vertically; the CENTER component may stretch both horiz- ontally and vertically to fill any space left over.

Method Summary

void	addLayoutComponent(Component component_, java.lang.Object constraint_)
void	doLayout(Container container_) This is called when the size of the container has already been set.
void	invalidateLayout(Container target_) Invalidates the layout, indicating that if the layout manager has cached information it should be discarded.
Dimension	minimumSize(Container container_) Calculate the minimum-size rectangle that can enclose all the components in the given container.
