• 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

  See Also:

  BasicLookAndFeel.initClassDefaults(javax.swing.UIDefaults)

  Returns the look and feel defaults. This invokes, in order, createDefaultTheme(), super.getDefaults() and getCurrentTheme().addCustomEntriesToTable(table).

  While this method is public, it should only be invoked by the UIManager when the look and feel is set as the current look and feel and after initialize has been invoked.

  Returns:

  the look and feel defaults

• provideErrorFeedback

  public void provideErrorFeedback(Component component)

  Overrides:

  provideErrorFeedback in class LookAndFeel

  Parameters:

  component - the Component the error occurred in, may be null indicating the error condition is not directly associated with a Component

  Since:

• 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

  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.

  Some look and feels might not render the disabled Icon, in which case they will ignore this.

                                      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.

  Parameters:

  component - JComponent that will display the Icon, may be null
