我在 jpanel 上替换 jmenubar 时遇到问题

Question

I am writing a desktop application using java swing with netbeans gui manager. I want replace vertical menu with submenus on Jpanel but when I am putting Jmenubar on Jpanel it does not work. I need some help with this.

Answer 1

A JMenubBar is designed to be added to the JFrame using the setJMenuBar(...) method.

If you want to use popup menus for other Swing components then you should be using a JPopupMenu .

Read the section from the Swing tutorial on How to Use Menus for more information and working examples to get you started.
