Communication between JFrames

Question

I have two frames, Frame A and Frame B. Now, how the frame A will know when a button on Frame B is pressed?

Frame A won't know, Frame B has to notify this to Frame A somewhere. — Luiggi Mendoza, Nov 05 '13 at 15:30

It won't. I would consider a design pattern such as mvc: http://tomdalling.com/blog/software-design/model-view-controller-explained/

You need to have some sort of background construction to allow for the jFrames to communicate. MVC allows changes in the information for one jFrame to affect another. It's a little conceptually complex but appears to be a generally accepted form for creating user interfaces. There are a lot of resources out there to help you learn the correct form

yes MVC is usually the way people go with something like this. Frame A would notify via an ActionListener the Controller (class), which then decides what to do with the action notification, and if appropriate, forwards it off to Frame B to perform some function.Think of the Controller as the Traffic Guard for your program. – SnakeDoc Nov 05 '13 at 15:37
