Serializable
public class MetalLookAndFeel extends BasicLookAndFeel
Each of the ComponentUI
s provided by
MetalLookAndFeel
derives its behavior from the defaults table. Unless otherwise noted each of the ComponentUI
implementations in this package document the set of defaults they use. Unless otherwise noted the defaults are installed at the time installUI
is invoked, and follow the recommendations outlined in LookAndFeel
for installing defaults.
MetalLookAndFeel
derives it's color palette and fonts from MetalTheme
. The default theme is OceanTheme
. The theme can be changed using the setCurrentTheme
method, refer to it for details on changing the theme. Prior to 1.5 the default theme was DefaultMetalTheme
. The system property "swing.metalTheme"
can be set to "steel"
to indicate the default should be DefaultMetalTheme
.
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

MetalLookAndFeel
registers an entry for each of the classes in the package javax.swing.plaf.metal
that are named MetalXXXUI. The string XXX
is one of Swing's uiClassIDs. For the uiClassIDs
that do not have a class in metal, the corresponding class in javax.swing.plaf.basic
is used. For example, metal does not have a class named
"MetalColorChooserUI"
, as such,
javax.swing.plaf.basic.BasicColorChooserUI
is used.initClassDefaults

. After the theme is set, MetalLookAndFeel
needs to be re-installed and the uis need to be recreated. The following shows how to do this:
MetalLookAndFeel.setCurrentTheme(theme); // re-install the Metal Look and Feel UIManager.setLookAndFeel(new MetalLookAndFeel()); // Update the ComponentUIs for all Components. This // needs to be invoked for all windows. SwingUtilities.updateComponentTreeUI(rootComponent);If this is not done the results are undefined.

with a disabled appearance. This method is used to generate a disabled Icon
when one has not been specified. For example, if you create a JButton
and only specify an Icon
via setIcon
this method will be called to generate the disabled Icon
. If null is passed as icon
this method returns null. Some look and feels might not render the disabled Icon, in which case they will ignore this.

for use by disabled components that are also selected. This method is used to generate an Icon
for components that are in both the disabled and selected states but do not have a specific Icon
for this state. For example, if you create a JButton
and only specify an Icon
via setIcon
this method will be called to generate the disabled and selected Icon
. If null is passed as icon
this method returns null. Some look and feels might not render the disabled and selected Icon, in which case they will ignore this.
