java - Override Swing Nimbus L&F primary color per component instance

Question

i’m trying to override the “nimbusBase” color for specific instance of JButton/JTabbedPane with no luck. only the specific attributes of the component e.g. “Button.background”, are working. any idea?

UIDefaults dialogTheme = new UIDefaults();
// dialogTheme.put(“nimbusBase”, Color.orange);
// dialogTheme.put("nimbusBlueGrey", Color.blue);
dialogTheme.put("Button.background", Color.yellow);
JButton dialogButton = new JButton("North");
dialogButton.putClientProperty("Nimbus.Overrides.InheritDefaults", true);
dialogButton.putClientProperty("Nimbus.Overrides", dialogTheme);

Answer 1

You can put the Color to the LookAndFeelDefaults for all Components "nimbusBase"

UIDefaults defaults = UIManager.getLookAndFeelDefaults();
defaults.put("nimbusBase", new ColorUIResource(210, 0, 210));

Or to a specific Component as you wrote it. Perhaps with update the componentTreeUI.

...
dialogTheme.put("Button.background", new ColorUIResource(0, 0, 210));
...
dialogButton.putClientProperty("Nimbus.Overrides", dialogTheme);
SwingUtilities.updateComponentTreeUI(dialogButton); 

I never override "nimbusBase" for a specific Component.

I found a nice Nimbus Theme Creator, which can show the effect of changing a Nimbus Default Color to all Components: http://aephyr.googlecode.com/svn/trunk

EDIT

You can 'copy' the Painter, modify them and set them via UIDefaults:

Example GUI with an nimbusOrange JTabbedPane and a normal one.

public class Example {

    static public void main( String[] s ) throws Exception {
        for (LookAndFeelInfo info : UIManager.getInstalledLookAndFeels()) {
            if ("Nimbus".equals(info.getName())) {
                UIManager.setLookAndFeel(info.getClassName());
                break;
            }
        }

        EventQueue.invokeLater( new Runnable() {
            @Override
            public void run() {
                JFrame frame = new JFrame();
                frame.getContentPane().setLayout( new BorderLayout() );
                frame.setBounds( 50, 50, 600, 600 );
                frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );

                JTabbedPane pane = new JTabbedPane();
                pane.addTab( "Lorem", new JLabel("Lorem") );
                pane.addTab( "Ipsum", new JLabel("Ipsum") );
                pane.addTab( "Dolor", new JLabel("Dolor") );
                pane.addTab( "Sit", new JLabel("Sit") );
                pane.addTab( "Amet", new JLabel("Amet") );

                UIDefaults dialogTheme = new UIDefaults();
                dialogTheme.put("TabbedPane:TabbedPaneTab[Enabled].backgroundPainter", new Painter(Painter.BACKGROUND_ENABLED));
                dialogTheme.put("TabbedPane:TabbedPaneTab[Disabled].backgroundPainter", new Painter(Painter.BACKGROUND_DISABLED));
                dialogTheme.put("TabbedPane:TabbedPaneTab[Enabled+MouseOver].backgroundPainter", new Painter(Painter.BACKGROUND_ENABLED_MOUSEOVER));
                dialogTheme.put("TabbedPane:TabbedPaneTab[Enabled+Pressed].backgroundPainter", new Painter(Painter.BACKGROUND_ENABLED_PRESSED));
                dialogTheme.put("TabbedPane:TabbedPaneTab[Selected].backgroundPainter", new Painter(Painter.BACKGROUND_SELECTED));
                dialogTheme.put("TabbedPane:TabbedPaneTab[Disabled+Selected].backgroundPainter", new Painter(Painter.BACKGROUND_SELECTED_DISABLED));
                dialogTheme.put("TabbedPane:TabbedPaneTab[Focused+Selected].backgroundPainter", new Painter(Painter.BACKGROUND_SELECTED_FOCUSED));
                dialogTheme.put("TabbedPane:TabbedPaneTab[MouseOver+Selected].backgroundPainter", new Painter(Painter.BACKGROUND_SELECTED_MOUSEOVER));
                dialogTheme.put("TabbedPane:TabbedPaneTab[Focused+MouseOver+Selected].backgroundPainter", new Painter(Painter.BACKGROUND_SELECTED_MOUSEOVER_FOCUSED));
                dialogTheme.put("TabbedPane:TabbedPaneTab[Pressed+Selected].backgroundPainter", new Painter(Painter.BACKGROUND_SELECTED_PRESSED));
                dialogTheme.put("TabbedPane:TabbedPaneTab[Focused+Pressed+Selected].backgroundPainter", new Painter(Painter.BACKGROUND_SELECTED_PRESSED_FOCUSED));
                dialogTheme.put("TabbedPane:TabbedPaneTabArea[Disabled].backgroundPainter", new AreaPainter(AreaPainter.BACKGROUND_DISABLED));
                dialogTheme.put("TabbedPane:TabbedPaneTabArea[Enabled+MouseOver].backgroundPainter", new AreaPainter(AreaPainter.BACKGROUND_ENABLED_MOUSEOVER));
                dialogTheme.put("TabbedPane:TabbedPaneTabArea[Enabled+Pressed].backgroundPainter", new AreaPainter(AreaPainter.BACKGROUND_ENABLED_PRESSED));
                dialogTheme.put("TabbedPane:TabbedPaneTabArea[Enabled].backgroundPainter", new AreaPainter(AreaPainter.BACKGROUND_ENABLED));
                pane.putClientProperty("Nimbus.Overrides.InheritDefaults", Boolean.TRUE);
                pane.putClientProperty("Nimbus.Overrides", dialogTheme);

                JTabbedPane secondPane = new JTabbedPane();
                secondPane.addTab( "Lorem", new JLabel("Lorem") );
                secondPane.addTab( "Ipsum", new JLabel("Ipsum") );
                secondPane.addTab( "Dolor", new JLabel("Dolor") );
                secondPane.addTab( "Sit", new JLabel("Sit") );
                secondPane.addTab( "Amet", new JLabel("Amet") );

                frame.getContentPane().setLayout( new BorderLayout() );
                frame.getContentPane().add( pane, BorderLayout.NORTH );
                frame.getContentPane().add( secondPane, BorderLayout.CENTER );
                frame.setVisible( true );
            }
        });
    }
}

NOTE: I removed the paint methods in this Painter example. Because this code was to long. Just add them via copy&past from com.sun.java.swing.plaf.nimbus.TabbedPaneTabbedPaneTabPainter.
