本文介绍了当标签放置设置为左侧时JTabbedpane标题的垂直方向的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
如下图所示，Java 文本是水平的.我想要做的是获得 JTabbedPane 标题的垂直方向.
As you can see from the image below, the Java text is horizontal. What I would like to do is get a vertical orientation of the JTabbedPane Titles.
在谷歌搜索时，我发现唯一的方法是添加额外的库.但我想知道这是否可以在没有任何额外库的情况下完成?
While googling, I found that the only way is to add extra library. But I was wondering if this can be done without any extra library?
我希望 Title1 和 Title2 是垂直方向而不是水平方向
I would like for Title1 and Title2 to be vertically oriented and not horizontally
推荐答案
你必须使用 Html 语法，对于禁用的 Tab 的任何更改也是
you have to use Html syntax, for any changes to the disabled Tab too
tabbedPane.addTab("<html>T<br>i<br>t<br>t<br>l<br>e<br>1</html>", panel1);
