设置新的Synthetica主题时，为什么我的JFrame不重新粉刷？

Question

I just set my applications theme to Synthetica Alu Oxide but some reason the JFrame doesn't repaint but another Synthetica theme will repaint the JFrame.

This is what mine looks like.

    public MainPanel() {
    JFrame frame = new JFrame();
    frame.setTitle("Asteria 3.0 NPC Definition Editor");

    try {
        UIManager.setLookAndFeel(new SyntheticaAluOxideLookAndFeel());
    } catch (UnsupportedLookAndFeelException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    components();       
    frame.setJMenuBar(menuBar);
    JTabbedPane tab = new JTabbedPane();
    tab.addTab("Information", informationTab());

    tab.addTab("Bonuses", bonusTab());
    tab.addTab("Animation", animTab());
    tab.addTab("Property", propertiesTab());
    tab.addTab("Miscellaneous", miscTab()); 

    frame.getContentPane().add(tab);
    //frame.add(this);
    frame.setSize(500, 600);
    frame.setResizable(false);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setVisible(true);     
}

Swing GUI objects should be constructed and manipulated only on the event dispatch thread , after you've invoked UIManager.setLookAndFeel() .

try {
    UIManager.setLookAndFeel(new SyntheticaAluOxideLookAndFeel());
} catch (UnsupportedLookAndFeelException e) {
    e.printStackTrace();
} catch (ParseException e) {
    e.printStackTrace();
}
EventQueue.invokeLater(new Runnable() {
    public void run() {
        JFrame frame = new JFrame();
        …
        frame.pack(true);
        frame.setVisible(true);
    }
});
