我可以使用带有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量。
I'm trying to increase the amount of space available for tab content.
如何在标签列表旁边放置菜单栏或等效文件? (最好在标签的左侧,与图像相对)
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
不是,如果没有覆盖整个BacisTabbedPaneUI直接不可能,所有的例子都是各种质量(看看感觉和本地操作系统非常敏感), aephyr的非常好的例子,
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,
我的观点JTabbedPane是*** JComponent,实现GlassPane的有趣例子(你为JMenuBar设置了一些边框,例如提出了etchech& line border ???: - )
my view JTabbedPane is *** JComponent, funny example by implements GlassPane (you have set a some Borders for JMenuBar e.g. raised etchech & line border ??? :-)
