public interface LayoutManager2 extends LayoutManager
Container
s based on a layout constraints object. This interface extends the LayoutManager
interface to deal with layouts explicitly in terms of constraint objects that specify how and where components should be added to the layout. This minimal extension to LayoutManager
is intended for tool providers who wish to create constraint-based layouts. It does not yet provide full, general support for custom constraint-based layout managers.
