我可以有一个带有 JMenuBar 的 JTabbedPane 吗? [英] Can I have a JTabbedPane with a JMenuBar?

问题描述

我正在尝试增加标签内容的可用空间.

I'm trying to increase the amount of space available for tab content.

如何在选项卡列表旁边放置菜单栏或等效项?(最好在选项卡的左侧，与图像相反)

How can I put a menu bar, or equivalent, next to a list of tabs? (preferably on the left of the tabs, opposite of image)

推荐答案

不，直接不可能不覆盖整个 BacisTabbedPaneUI，所有示例都是各种质量(外观和原生操作系统非常敏感)，aephyr 很好的例子，

not, directly not possible without override whole BacisTabbedPaneUI, all examples are various quality (look and feel and native os very sensitive), very good example by aephyr,

我认为 JTabbedPane 是 *** JComponent，实现 GlassPane 的有趣示例(您已经为 JMenuBar 设置了一些边框，例如凸起的蚀刻和线条边框 ??? :-)

my view JTabbedPane is *** JComponent, funny example by implements GlassPane (you have set a some Borders for JMenuBar e.g. raised etchech & line border ??? :-)
