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.

installUI to install the necessary state onto the passed in
JRootPane to render the metal look and feel implementation of
RootPaneUI. If the
windowDecorationStyle property of the
JRootPane is other than
JRootPane.NONE, this will add a custom
Component to render the widgets to
JRootPane, as well as installing a custom
Border and
LayoutManager on the
JRootPane.

LayoutManager of the
JRootPane. If a
Component has been added to the
JRootPane to render the window decoration style, this method will remove it. Similarly, this will revert the Border and LayoutManager of the
JRootPane to what it was before
installUI was invoked.

MetalRootPaneUI is primarily interested in events originating from the
JRootPane it has been installed on identifying the property
windowDecorationStyle. 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 as well resetting the Border to what it was before
installUI was invoked.
