Examples of java.awt.LayoutManager

java.awt.LayoutManager
Defines the interface for classes that know how to lay out Containers.
Swing's painting architecture assumes the children of a JComponent do not overlap. If a JComponent's LayoutManager allows children to overlap, the JComponent must override isOptimizedDrawingEnabled to return false. @see Container @see javax.swing.JComponent#isOptimizedDrawingEnabled @author Sami Shaio @author Arthur van Hoff
