NSDocument title

[JavaWizKid]

I've searched the whole internet for a solution to this with no avail

I've read about overriding

windowTitleForDocumentDisplayName

But I tried it like so:

- (void)windowControllerDidLoadNib:(NSWindowController *) aController

{

	[aController windowTitleForDocumentDisplayName:@"hey"];

    [super windowControllerDidLoadNib:aController];

And "hey" doesn't appear

How can I set the title of an NSDocument window?

Thanks
