JTabbedPane：选项卡本身之前和之后的组件
这类似于问题 如何在 Java Swing 中构建 Google-chrome 选项卡和菜单栏界面？（我想完成同样的任务），但更重要的是：如何将组件放在 JTabbedPane 中选项卡的前面和后面？
我自己已经提出了按钮的想法，但我宁愿有一个 JTabbedPane，因为它确实如此，但侧面装饰有按钮或图标。
我已经看到 Kirill 的 laf-widget 项目做了类似的事情（放大- 选项卡左侧的玻璃图标）用于多个 LaF。 然而，我必须承认，我还不够熟练，无法理解他是如何做到这一点的 - 而且这似乎是一个有点复杂的过程，其中一个人“物理地”改变有问题的 LaF（字节码操纵它），注入 laf - 将小部件内容放入 UI 委托中 - 我仍然不知道 JTabbedPane 或 TabbedPaneUI 实际上是如何调制以注入该图标/按钮的。
This is similar to the question How to build a Google-chrome tabs and menubar interface in Java Swing? (I want to accomplish the same), but more to the point: How do I put components in front and behind the tabs in a JTabbedPane?
I've already come up with the buttons-idea myself, but I'd rather have a JTabbedPane, since that is really what it is, but decorated with a button or icons on the sides.
I've seen that the laf-widget project from Kirill does something like it (the magnifying-glass icon to the left of the tabs) for several LaFs. However, I must admit that I'm not yet well enough versed to understand how he does it - and also it seems like a somewhat complicated process, whereby one "physically" change the LaF in question (bytecode manipulates it), injecting the laf-widget stuff into the UI delegates - and I still don't know how the JTabbedPane or TabbedPaneUI is actually modulated to inject that icon/button.

我最后向 Substance LaF/laf-widget 的基里尔询问了他如何设法将装饰 JTabbedPanes 的 laf-widget 选项卡前面的按钮，这是他的回复：
谢谢，基里尔！
I finally asked Kirill of Substance LaF/laf-widget of how he manages to put a button in front of the tabs in the laf-widget that decorates JTabbedPanes, and this is his reply:
Thanks, Kirill!
JIDE 有一个选项卡式窗格作为其组件套件的一部分，将该功能公开为简单的 setBeforeComponent() 和 setAfterComponent( ） 方法。
这里有一个演示： http://www.jidesoft.com/products/ 1.4/jide_demo.jnlp
JIDE have a tabbed pane as part of their component suite that exposes this functionality as simple setBeforeComponent() and setAfterComponent() methods.
There's a demo of it in here: http://www.jidesoft.com/products/1.4/jide_demo.jnlp
