I'm stuck with my school work in Java, where I'm building a TicTacToe game, using the MVC design pattern. I have three classes (Model, View, Controller) and I'm at the last step from having a final product. The problem IS:
My JTextFields WON'T keep their value that the user enters. What I'm trying to get is that the names chosen by the user will be stored and able to retrive through the controller back to the model. I've tried different methods, asked people for help and searched several forums.
I'm using the Observable interface together with these classes and have ActionEvent in controller.
Please, take a look and let me know what you think!
OBS! As you will se, I've tried several different ways to fix this, that's why the code looks like s*it....
