How can I customize the title bar on JFrame?
提问by Jonas
I would like to have a customized title bar in my Java Swing desktop application. What is the best way to do that? I can use a "Swing-title bar" by using the following code in the constructor for my JFrame:
我想在我的 Java Swing 桌面应用程序中有一个自定义的标题栏。最好的方法是什么？我可以通过在 JFrame 的构造函数中使用以下代码来使用“Swing-title bar”：
this.setUndecorated(true);
this.getRootPane().setWindowDecorationStyle(JRootPane.FRAME);
But how do I customize it? Is there any UI delegatesthat I can override or do I have to implement my own title bar from scratch?
但是我如何自定义它？是否有我可以覆盖的UI 委托，或者我是否必须从头开始实现我自己的标题栏？

You can see an example in Substance look-and-feel(mirrored source). Search the code for SubstanceRootPaneUI and SubstanceTitlePane. The implementation depends on other classes in Substance, and will not be easy to reuse outside the specific library - nor is it meant to.
您可以在Substance 外观（镜像源）中看到一个示例。搜索 SubstanceRootPaneUI 和 SubstanceTitlePane 的代码。实现依赖于 Substance 中的其他类，并且不容易在特定库之外重用 - 也不是故意的。
