public interface 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.

Container, JComponent.isOptimizedDrawingEnabled()
