Windows 和 macOS 中 GUI 的差异

问题描述 投票：0回答：2

我是一名Windows用户，我开发了一个小程序来根据一些输入计算一些参数。 Windows 中的 GUI 按预期显示，但在 macOS 中却有所不同。请让我知道如何纠正它。相同的代码是。

按钮看起来不同的原因是 Java Swing 的 LAF (Look & Feel)。

外观就像 Swing 应用程序的主“主题”，它定义了某些组件的外观等具体规则……

Windows 上的 Java Swing 看起来与 Unix 和 OSX 上不同，因为 LAF 有不同的提供者（称为 LAF“金属”）

因此，您可以将 LAF 库打包到您的程序中，您可以在here找到许多库。 要调用要使用的主题，您必须将其放置在调用任何 GUI/Swing 事件（也称为重绘、组件初始化等）之前：

try {
   UIManager.setLookAndFeel(myThemeLAF.class.getName());
} catch (UnsupportedLookAndFeelException | ClassNotFoundException | InstantiationException | IllegalAccessException e) {
   e.printStackTrace();
}

或者，您可以重写各个 

paintComponent(Graphics g)
方法。

这可以通过匿名类或仅让一个类扩展该对象并从那里覆盖它来实现：

  • #1 匿名内部类
JPanel myPanel = new JPanel() {
   @Override
   public void paintComponent(Graphics g) {
      super.paintComponent(g);
      //... draw stuffs
   }
};
  • #2 扩展现有对象
public class MyPanel extends JPanel {
   @Override
   public void paintComponent(Graphics g) {
      super.paintComponent(g);
      // paint stuffs
   }
}

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

我在main的开头插入了这段代码并解决了它
