JFrame没有正确加载

我创建了一个包含多个类的Java项目，其中一个是Shell.java。这将启动一个GUI（使用swing），其中按钮和图像可以使用className.main(args);

启动其他类

除了一个按钮之外，这个工作正常，但我已经像其他所有人一样对该部分进行了编码......（下面的代码）：

File morseFile = new File("c:\\temp\\morse.png");
Icon morseIcon = new ImageIcon(morseFile.getAbsolutePath());
JButton morseButton = new JButton(morseIcon);
morseButton.setBorder(emptyBorder);
morseButton.setContentAreaFilled(false);    
morseButton.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent event) {
        Morsecodes.main(args);
    }
});

如果我在Morsecodes.jar中启动main方法，一切正常。但是，如果我从shell类启动它，那么会发生这种情况：

如您所见，它首先打印背景，但永远不会改变。如果按下X，它也不会关闭，我必须强制它通过任务管理器关闭。

我已经尝试过改变Morsecodes.jar所以我可以做（也没有工作）：

morseButton.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent event) {
        new Morsecodes();
    }
});

运行另一个main方法的所有其他按钮工作正常。

据我了解这个问题：

当您点击JButton(morseIcon)按钮时，会调用Shell main，其中包含无限循环while(true)，因此无法重新绘制您的窗口，甚至退出申请。

  • 您可以将main调用到新主题中：

    new Thread（（） - ＆gt; Morsecodes :: main）.start（）;

  • 或者将你的循环放入线程......
