当我设置一个新的 Synthetica 主题时，为什么我的 JFrame 没有重新绘制? [英] Why doesn't my JFrame repaint when I set a new Synthetica theme?

问题描述

我只是将我的应用程序主题设置为 Synthetica Alu Oxide，但出于某种原因 JFrame 不会重新绘制，但另一个 Synthetica 主题会重新绘制 JFrame.

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.

这就是我的样子.

这就是它的样子.

    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);     
}

推荐答案

Swing GUI 对象应仅在 事件调度线程，在你调用了UIManager.setLookAndFeel().

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);
    }
});
