Hi Steven,
the error seems to occur in your code, and it is difficult to guess what is the problem without seeing the code!
One possible thing to check for: Does your Gui class have a constructor? If it extends some other (super-)class, and you have somewhere
Gui myGui = new Gui();
or
new Gui().someMethodOfGui(args);
you need a constructor. The default would be
public class Gui extends SuperGuiClass {
public Gui() {
super();
}
// and the rest of the code ...
}
A typical way to get such an error seems to be if a no-argument constructor SuperGuiClass() does not exist. In this case, you might call super(someNiceDefaultArguments) in the constructor.
Michael
