Question

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。但是我想知道如果没有任何额外的库可以做到这一点吗？

我希望 Title1 和 Title2 垂直定位而不是水平

你必须使用Html语法，对禁用的Tab也进行任何更改

tabbedPane.addTab("<html>T<br>i<br>t<br>t<br>l<br>e<br>1</html>", panel1);

修改

Answer 2

如果您使用WebLaf LoolAndFeel库有一个名为WebVerticalLabel的组件可以包含垂直文本。

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

当制表符放置设置为LEFT时，JTabbedPane标题的垂直方向
