Class BorderUIResource
- Border, Serializable, UIResource
A wrapper for
Border that also
implements the
UIResource 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
UIResource. For this reason, a look-and-feel
should always install borders that implement
UIResource, such as the borders provided by this
class.
