Difference Between JFrame & JWindow?

JWindow doesn't have a title bar, minimize-maximize buttons. In java terminology..it is undecorated. The components cannot be added and a layout cannot be assigned directly to the JWindow. Instead it can be done to contentpane in JWindow.

JFrame on the other hand has all the above. It is decorated (title bar, minimize-maximize buttons) and commponents & layout can be added directly to it.

I hope this helps.

Hi Friends,

The JWindow is a top-level container, but without any embellishments like minimis/maximise buttons. It can be used straight against the desktop, but you usually use JFrame instead.


JWindow does not have the title bar, window-management buttons, or other trimmings associated with a JFrame. Think of it as a window without a border.

One thing you should also notice that is instead of adding to the window itself like you could with a JFrame, you want to make sure that you add to the Content Pane of the window.

Thanks,
