java.lang.Objectjavax.swing.plaf.BorderUIResource
public class BorderUIResource
A wrapper for Border
that also
implements the BorderUIResource.BevelBorderUIResource
marker interface. This is useful
for implementing pluggable look-and-feels: When switching the
current LookAndFeel, only those borders are replaced that are
marked as BorderUIResource.BevelBorderUIResource
. For this reason, a look-and-feel
should always install borders that implement
UIResource
, such as the borders provided by this
class.
