java - JFrame inside another JFrame

Question

I have a game of chess. I have written 3 classes. 1st if for game. (chessboard, pieces, and so on) And another one is for menu. (buttons like new, open, set time)

Both of them use JFrame.

I would like to put both classes mentioned above into the 3rd class. For example the Game window would be on the left, and the menu on the right. The third class would also show the whole app by JFrame.

How to do that?

Answer 1

You can't put one JFrame inside another. You have a couple of design choices here. You can change your JFrames to JPanels. This is probably the easiest change. On the other hand, you can look at using Internal Frames instead.
