public class BorderUIResource extends Object implements Border, UIResource, Serializable
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.Modifier and Type | Class and Description |
