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.

Method Details
-
createUI
Creates a UI for aJRootPane
.- Parameters:
c
- the JRootPane the RootPaneUI will be created for- Returns:
- the RootPaneUI implementation for the passed in JRootPane
-
installUI
Invokes supers implementation ofinstallUI
to install the necessary state onto the passed inJRootPane
to render the metal look and feel implementation ofRootPaneUI
. If thewindowDecorationStyle
property of theJRootPane
is other thanJRootPane.NONE
, this will add a customComponent
to render the widgets toJRootPane
, as well as installing a customBorder
andLayoutManager
on theJRootPane
.- Overrides:
installUI
in classComponentUI
- Parameters:
c
- the JRootPane to install state onto- See Also:
ComponentUI.uninstallUI(javax.swing.JComponent)
,JComponent.setUI(javax.swing.plaf.ComponentUI)
,JComponent.updateUI()
-
uninstallUI
Invokes supers implementation to uninstall any of its state. This will also reset theLayoutManager
of theJRootPane
. If aComponent
has been added to theJRootPane
to render the window decoration style, this method will remove it. Similarly, this will revert the Border and LayoutManager of theJRootPane
to what it was beforeinstallUI
was invoked.- Overrides:
uninstallUI
in classComponentUI
- Parameters:
c
- the JRootPane to uninstall state from- See Also:
ComponentUI.installUI(javax.swing.JComponent)
,JComponent.updateUI()
-
propertyChange
Invoked when a property changes.MetalRootPaneUI
is primarily interested in events originating from theJRootPane
it has been installed on identifying the propertywindowDecorationStyle
. If thewindowDecorationStyle
has changed to a value other thanJRootPane.NONE
, this will add aComponent
to theJRootPane
to render the window decorations, as well as installing aBorder
on theJRootPane
. On the other hand, if thewindowDecorationStyle
has changed toJRootPane.NONE
, this will remove theComponent
that has been added to theJRootPane
as well resetting the Border to what it was beforeinstallUI
was invoked.- Specified by:
