How do I make a NSWindow popup when a button is pressed

Question

I have a small itty bitty help button in my cocoa program. I was wondering how to make it, when pressed, to make a small nswindow panel popup, with lots of text on it. How can I do this? The button is called help and the window can be called helpwin

Answer 1

I figured it out. All I had to do is create the @property for my panel. Then in my button IBAction, I wrote

- (IBAction)help:(id)sender {
    if (![self.helpWin isVisible]) {
        [self.helpWin makeKeyAndOrderFront:sender];
    }
}

And it works!
