我可以使用带有JMenuBar的JTabbedPane吗？

Question

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

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)

Answer 1

You can use JideTabbedPane from jide.

Jide is commerical library, but this JideTabbedPane class are open source, get source code here: http://java.net/projects/jide-oss/

the screenshot is like below.

Answer 2

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 ,

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