public interface LayoutManager
Defines the interface for classes that know how to lay out Container
s.
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.
