Module java.desktop
Package javax.swing.plaf.metal

Class MetalLookAndFeel

  • All Implemented Interfaces:
    Serializable
    public class MetalLookAndFeel
extends BasicLookAndFeel
    The Java Look and Feel, otherwise known as Metal.

    Each of the ComponentUIs 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.

      • initClassDefaults

        protected void initClassDefaults​(UIDefaults table)
        Populates table with mappings from uiClassID to the fully qualified name of the ui class. 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.
        Overrides:
        initClassDefaults in class BasicLookAndFeel
        Parameters:
        table - the UIDefaults instance the entries are added to
        Throws:
        NullPointerException - if table is null

      • provideErrorFeedback

        public void provideErrorFeedback​(Component component)

      • setCurrentTheme

        public static void setCurrentTheme​(MetalTheme theme)
        Set the theme used by MetalLookAndFeel.

        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.
        Parameters:
        theme - the theme to use
        Throws:
        NullPointerException - if theme is null

      • getDisabledIcon

        public Icon getDisabledIcon​(JComponent component,
                            Icon icon)
        Returns an Icon 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.

        Overrides:
        getDisabledIcon in class LookAndFeel
        Parameters:
        component - JComponent that will display the Icon, may be null
        icon - Icon to generate disable icon from.

        public Icon getDisabledSelectedIcon​(JComponent component,
                                    Icon icon)
        Returns an Icon 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.

        Overrides:
        getDisabledSelectedIcon in class LookAndFeel
        Parameters:
        component - JComponent that will display the Icon, may be null
