How to create vertical tabs in Java?
提问by bancer
I would like to get the effect like if JTabbedPane would be turned 90 degrees counterclockwise (only tabs but not the content inside tabs). What is the best way to implement that in Java?
我想获得 JTabbedPane 逆时针旋转 90 度的效果（只有选项卡，而不是选项卡内的内容）。在 Java 中实现它的最佳方法是什么？

The text was painted vertically and tried as an icon on the tab. This way you don't have to modify JTabbedPane you just use a custom Icon in the tab.
文本被垂直绘制并尝试作为选项卡上的图标。这样您就不必修改 JTabbedPane，您只需在选项卡中使用自定义图标。
Of course you would also have to specify the tab placement to be on the Left.
当然，您还必须指定选项卡放置在左侧。

You can specify the placement in the constructor:
您可以在构造函数中指定位置：

or in the setter:
或在二传手：

As an alternative, consider JToolBarwith orientationset to VERTICALin a BorderLayout, EASTor WEST. It's fairly easy rotate textin the button's Icon.
作为替代方案，考虑JToolBar与orientation设置为VERTICAL一个BorderLayout，EAST或WEST。这也很容易旋转文本按钮的Icon。

You could try and extend the tabpane class, in the overloaded paint method, get the graphics object, say g2dis the argument of the overloaded paint method:
您可以尝试扩展 tabpane 类，在重载的paint方法中，获取图形对象，比如说g2d是重载paint方法的参数：
super(g2d.rotate(Pi/2));
