        setFrameTheme();
    }

}

我得到错误：

java.lang.IllegalStateException: This method must be called on the Event Dispatch Thread
    at org.pushingpixels.substance.api.SubstanceLookAndFeel.setSkin(SubstanceLookAndFeel.java:1970)
    at org.pushingpixels.substance.api.SubstanceLookAndFeel.setSkin(SubstanceLookAndFeel.java:2086)
    at loader.Loader.main(Loader.java:126)

请告诉我要更改或添加的内容。

谢谢你。

Swing GUI 应该在 Event Dispatch Thread 上构建和更改。有关更多详细信息，请参阅Swing 中的并发，尤其是初始线程。

下面是在 EDT 上创建 GUI 的示例：

public static void main(String[] args) {
    Runnable r = new Runnable() {

        @Override
        public void run() {
            ImageTimeTunnel itt = new ImageTimeTunnel();

            JFrame f = new JFrame("Image Time Tunnel");
            f.add(itt.getGUI());
            // Ensures JVM closes after frame(s) closed and
            // all non-daemon threads are finished
            f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

            // ensures the frame is the minimum size it needs to be
            // in order display the components within it
            f.pack();

            // See http://stackoverflow.com/a/7143398/418556 for demo.
            // f.setLocationByPlatform(true);
            f.setLocationRelativeTo(null);

            // should be done last, to avoid flickering, moving,
            // resizing artifacts.
            f.setVisible(true);
        }
    };
    // Swing GUIs should be created and updated on the EDT
    // http://docs.oracle.com/javase/tutorial/uiswing/concurrency
    SwingUtilities.invokeLater(r);
}

我使用 Eclipse，当我制作 JFrame 时，它​​会为事件调度线程生成一些代码。

尝试在 main 方法中使用它：

    EventQueue.invokeLater(new Runnable() {
        public void run() {
            try {

                GraphiteGlassSkin darkSkin = new GraphiteGlassSkin();
                SubstanceLookAndFeel.setSkin(darkSkin);
                UIManager.setLookAndFeel("org.pushingpixels.substance.api.skin.SubstanceGraphiteGlassLookAndFeel");

                Frame frame = new Frame();
                frame.setVisible(true);

            } catch (Exception e) {
                e.printStackTrace();
            }
        }

    });

我相信这与 Andrew 的代码相同，只是在同一行中创建和调用 runnable。

我正在使用物质 7.1.01。
