RootPaneUI.
MetalRootPaneUI provides support for the
windowDecorationStyle property of JRootPane.
MetalRootPaneUI does this by way of installing a custom
LayoutManager, a private Component to render
the appropriate widgets, and a private Border. The
LayoutManager is always installed, regardless of the value of
the windowDecorationStyle property, but the
Border and Component are only installed/added if
the windowDecorationStyle is other than
JRootPane.NONE.
Warning:
Serialized objects of this class will not be compatible with
future Swing releases. The current serialization support is
appropriate for short term storage or RMI between applications running
the same version of Swing. As of 1.4, support for long term storage
of all JavaBeans
has been added to the java.beans package.
Please see XMLEncoder.
