Java：JTabbedPane选项卡标题中的JProgressBar（或等效项） [英] Java: JProgressBar (or equivalent) in a JTabbedPane tab title

问题描述

如果我真的想做类似的事情，我可以在JTabbedPane标签中放一个JProgressBar（或它的等价物）吗？ （我的意思是，不在标签本身，

If I really wanted to do something like that, can I put a JProgressBar (or it's equivalent) in a JTabbedPane tab? (I mean, not in the tab itself,

我该怎么做？

编辑我确实想把进度条放在标签的标题中，而不是标签本身。

EDIT I really do want to put the progressbar in the title of the tab, not the tab itself.

这里有一些ascii艺术：

Here's some ascii art:

----------------------------------------------------
|  Tab 1  || Tab   2||Tab-with-progress-bar||Tab  4|
-----------         --------------------------------
'                                                  '
'                                                  '
'                                                  '
'                                                  '
'                                                  '
'                                                  '
'                                                  '
'                                                  '
----------------------------------------------------

所以它真的是tab 2，目前可见，但我想要进度条（或同等）在第三个标签的标题中可见。

So it's really "tab 2" that is currently visible, but I want the progress bar (or equivalent) to be visible in the third tab's title.

编辑2

这必须适用于Java 1.5：这必须适用于永远不会配备Java 6的无数MacOS 10.4和MacOS 10.5 Apple计算机（有些不做，有些则没有：并且相当多的永远不会，这不是我的电话）

This has to work on Java 1.5: this has to work on the countless MacOS 10.4 and MacOS 10.5 Apple computers that will never be equipped with Java 6 (some do, some don't: and quite a lot never will, it is not my call)

推荐答案

将JProgressbar包含在JPanel中并将JPanel添加到JTabbedPane。

Enclose the JProgressbar in a JPanel and add that JPanel to the JTabbedPane.

编辑：来自 JTabbedPane JavaDoc ：

//在这种情况下，自定义组件
负责呈现选项卡的
标题。

// In this case the custom component is responsible for rendering the title of the tab.

tabbedPane.addTab(null, myComponent); 
tabbedPane.setTabComponentAt(0, new JLabel("Tab"));

所以你基本上可以简单地替换新的JLabel（Tab）引用你的JProgressbar（虽然不能将这个JProgressbar添加到Tab本身）。
但是，我认为此方法在Java 1.6之前不存在。

So you could basically simply replace new JLabel("Tab") by a reference to your JProgressbar (though this JProgressbar must not be added to the Tab itself). However, I think this method doesn't exist prior to Java 1.6.
