Class AlignLayout

java.lang.Object
  com.alee.extended.layout.AbstractLayoutManager
      com.alee.extended.layout.AlignLayout

All Implemented Interfaces:

java.awt.LayoutManager, java.awt.LayoutManager2, javax.swing.SwingConstants

public class AlignLayout
extends AbstractLayoutManager
implements javax.swing.SwingConstants

This layout allows you to align components inside the container using the standart Swing constants.
