更改 JButton 的外观和感觉

Question

我想在我的应用程序中使用 nimbus 按钮样式。我不想改变 L&F。只需更改按钮的 L&F 即可使用 Nimbus L&F。有办法做到这一点吗？

可能有更好的方法，但以下实用程序类应该适合您：

import javax.swing.JButton;
import javax.swing.LookAndFeel;
import javax.swing.UIManager;
import javax.swing.UIManager.LookAndFeelInfo;


public class NimbusButton {
    private static LookAndFeel nimbus;

    public static JButton generateNimbusButton() {
        try {
            LookAndFeel current = UIManager.getLookAndFeel(); //capture the current look and feel

            if (nimbus == null) { //only initialize Nimbus once
                for (LookAndFeelInfo info : UIManager.getInstalledLookAndFeels()) {
                    if ("Nimbus".equals(info.getName())) {
                        UIManager.setLookAndFeel(info.getClassName());
                        break;
                    }
                }
                nimbus = UIManager.getLookAndFeel();
            }
            else
                UIManager.setLookAndFeel(nimbus); //set look and feel to nimbus
            JButton button = new JButton(); //create the button
            UIManager.setLookAndFeel(current); //return the look and feel to its original state
            return button;
        }
        catch (Exception e) {
            e.printStackTrace();
            return new JButton();
        }
    }
}

generateNimbusButton() 方法将外观更改为 Nimbus，创建按钮，然后将外观更改回调用该方法时的状态。
