NSTextField enter to trigger action

Question

I've been looking all over for a simple example of how to have an action (or button) be triggered when the enter key is hit in the text field.

Should I subclass the text field? Would I need to set a delegate to call the action I need? Is there a way to catch the event in my main window controller class?

If you could even just point me to the right direction that would be great. Thanks.

Answer 1

You need to set the delegate of the text field, then do your action in (BOOL)textFieldShouldReturn:(UITextField *)textField. For instance:

-(void)viewDidLoad {
    UITextField *field = //etc
    field.delegate = self;
}

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    //do stuff here
    return YES;
}

EDIT: Oops, sorry, didn't see you're programming for mac. Ignore the above.

Answer 2

Just connect an IBAction of your controller class with a text field. The action should be called with you hit enter or leave the text field with Tab or Mouse.

Answer 3

To get action after you hit enter just write an IBAction in your window controller and connect to your text field. If you want more like your method should be called when you focus on text field and leave the text field you need to set delegate(See here).
