我怎样才能改变JFrame的标题栏的颜色？

我正在使用下面的代码，

UIManager.put("JFrame.activeTitleBackground", Color.red); 

用于更改JFrame中的工具栏颜色。 但它没有工作。

是否有可能改变JFrame的标题栏的颜色？

Answer 1

这是不可能的。 顶级JFrame由底层操作系统的外观和感觉控制。

您可以更改InternalFrame的颜色。

 UIManager.put("InternalFrame.activeTitleBackground", new ColorUIResource(Color.black )); UIManager.put("InternalFrame.activeTitleForeground", new ColorUIResource(Color.WHITE)); UIManager.put("InternalFrame.titleFont", new Font("Dialog", Font.PLAIN, 11));
