Cocoa: Making NSTextField editable after a click and short delay (like renaming in Finder)

I cannot find a simple example of how to use an NSTextField to edit it's contents in place.

Exactly like in the Finder - you're able to click, and with a short delay the text field becomes editable.

It seems like it's some combination of the textField, it's cell, and the fieldEditor? Problem is I can't find the most basic example of how to do it.

I've tried subclassing NSTextField with a couple different tests but it hasn't worked:

#import "GWTextField.h"
@implementation GWTextField
- (id) initWithFrame:(NSRect)frameRect {
    self = [super initWithFrame:frameRect];
    return self;
}
- (void) mouseDown:(NSEvent *)theEvent {
    [super mouseDown:theEvent];
    [self.cell editWithFrame:self.frame inView:self.superview editor:[self.cell fieldEditorForView:self] delegate:self event:theEvent];
    //[self setEditable:TRUE];
    //[self setSelectable:TRUE];
    //[self selectText:nil];
    [NSTimer scheduledTimerWithTimeInterval:.3 target:self selector:@selector(edit:) userInfo:nil repeats:FALSE];
}
- (void) edit:(id) sende {
    NSLog(@"edit");
    [[NSApplication sharedApplication].mainWindow makeFirstResponder:self];
    [self selectText:nil];
}
@end

Any ideas?

I came up with a better solution to the edit in place problem. I believe this is how to properly do edit in place with NSCell. Please show and tell if this is wrong.

#import <Cocoa/Cocoa.h>
@interface EditTextField : NSTextField <NSTextDelegate>
@end

#import "EditTextField.h"

@implementation EditTextField

- (void) mouseDown:(NSEvent *)theEvent {
    if(theEvent.clickCount == 2) {
        self.editable = TRUE;
        NSText * fieldEditor = [self.window fieldEditor:TRUE forObject:self];
        [self.cell editWithFrame:self.bounds inView:self editor:fieldEditor delegate:self event:theEvent];
    } else {
        [super mouseDown:theEvent];
    }
}

- (void) cancelOperation:(id)sender {
    [self.cell endEditing:nil];
    self.editable = FALSE;
}

- (BOOL) textView:(NSTextView *) textView doCommandBySelector:(SEL) commandSelector {
    NSString * selector = NSStringFromSelector(commandSelector);
    if([selector isEqualToString:@"insertNewline:"]) {
        NSText * fieldEditor = [self.window fieldEditor:TRUE forObject:self];
        [self.cell endEditing:fieldEditor];
        self.editable = FALSE;
        return TRUE;
    }
    return FALSE;
}

@end
