当制表符放置设置为LEFT时，JTabbedPane标题的垂直方向

从下图中可以看出，Java文本是水平的。 我想做的是获得JTabbedPane标题的垂直方向。

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？

我想Title1和Title2是垂直方向而不是水平方向

您必须使用Html语法，对禁用的Tab也进行任何更改

tabbedPane.addTab("T
i
t
t
l
e
1", panel1);

如果您使用WebLaf LoolAndFeel库有一个名为WebVerticalLabel的组件可以具有垂直文本。

 JTabbedPane .setTabComponentAt(1, new WebVerticalLabel("Title1"));
