【Java】Java GUI改变界面风格

✨UIManager

//        Metal风格(默认)
        String lookAndFeel ="javax.swing.plaf.metal.MetalLookAndFeel";
//        Windows风格
        String lookAndFeel ="com.sun.java.swing.plaf.windows.WindowsLookAndFeel";
//        Windows Classic风格
        String lookAndFeel ="com.sun.java.swing.plaf.windows.WindowsClassicLookAndFeel";
//        Motif风格
        String lookAndFeel ="com.sun.java.swing.plaf.motif.MotifLookAndFeel";
//        Mac风格 (需要在相关的操作系统上方可实现)
        String lookAndFeel ="com.apple.laf.AquaLookAndFeel";
//        GTK风格 (需要在相关的操作系统上方可实现 未验证)
        String lookAndFeel ="com.sun.java.swing.plaf.gtk.GTKLookAndFeel";
//        可跨平台的默认风格
        String lookAndFeel =UIManager.getCrossPlatformLookAndFeelClassName();
//        当前系统的风格
        String lookAndFeel =UIManager.getSystemLookAndFeelClassName();

选择一种界面风格后调用

！必须使用try - catch 环绕

try {
    UIManager.setLookAndFeel(lookAndFeel);
} catch (Exception e) {
    e.printStackTrace();
}

✨JFrame

JFrame.setDefaultLookAndFeelDecorated(true);

！需要写在调用JFrame构造方法之前

✨JDialog

JDialog.setDefaultLookAndFeelDecorated(true);

！需要写在调用JDialog构造方法之前
