Question

I have made some code to do this, but as It doesn’t work. I am only a beginner so I may be doing this completely wrong or i may have missed something out. Either way please tell me. Here is the code I have got.

[item setAction:(SEL)action {
        [window makeKeyAndOrderFront:NSApp];
    }

It looks like you’re trying to make an anonymous function. AFAIK, Obj-C has no support for these. Basically want you want to do is define action as a proper method:

[item setAction:@selector(action:)];

…

-(void)action:(id)sender{  
    [window makeKeyAndOrderFront:self];  
}

Also, I’m not sure why you’re passing NSApp to makeKeyAndOrderFront:. The full signature is - (void)makeKeyAndOrderFront:(id)sender, so passing self is usually most appropriate (although I’m not even sure what that input does!).

I suggest you work through a few tutorials to familiarize yourself with Obj-C and Cocoa.
