Class Overview
Provides the metal look and feel implementation of 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 JavaBeansTM
has been added to the java.beans package.
Please see XMLEncoder.

Public Methods
public static ComponentUI createUI (JComponent c)
Creates a UI for a JRootPane.
Parameters
| c | the JRootPane the RootPaneUI will be created for |
|---|
Returns
- the RootPaneUI implementation for the passed in JRootPane
public void installUI (JComponent c)
Invokes supers implementation of 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.
Parameters
| c | the JRootPane to install state onto |
|---|
public void propertyChange (PropertyChangeEvent e)
Invoked when a property changes. 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.
Parameters
| e | A PropertyChangeEvent object describing the event source and the property that has changed. |
|---|
public void uninstallUI (JComponent c)
Invokes supers implementation to uninstall any of its state. This will
also reset the 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.
Parameters
| c | the JRootPane to uninstall state from |
|---|
