java - Swing应用无法运行

我在使用秋千时遇到问题。我不知道这是什么原因，但我只是想使用swing创建一个简单的框架应用程序，这给了我很多错误。

    import javax.swing.JFrame;
public class StacksGui {
public static void main(String args[])
     JFrame frame = new JFrame();
     frame.setVisible(true);
     frame.setSize(100,200);
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}

最佳答案

当所有java Swing应用程序无声崩溃时，我遇到了问题。
尝试从命令行启动后，出现以下异常：

Caused by: java.lang.IllegalArgumentException: 181193932 incompatible with Text-specific LCD contrast key

如JDK-6503988中所述，问题与ClearType注册表设置FontSmoothingGamma有关。

可以通过从控制面板（cttune.exe）运行“ Adjust ClearType text”或直接通过changing the registry来解决此问题：

reg add "HKEY_CURRENT_USER\Control Panel\Desktop" /t REG_DWORD /v FontSmoothingGamma /d 1024 /f

可能需要重新启动才能使更改生效。
