public class MetalRootPaneUI extends BasicRootPaneUI
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

. If the windowDecorationStyle
has changed to a value other than JRootPane.NONE
, this will add a Component
to the JRootPane
to render the window decorations, as well as installing a Border
on the JRootPane
. On the other hand, if the windowDecorationStyle
has changed to JRootPane.NONE
, this will remove the Component
that has been added to the JRootPane
