how do i reference the window associated with a nswindowcontroller - macos

Question

I have a subclassof NSWindowController with an associated xib file.
From my app delegate I display this using the following code:
if(!wc)
wc = [[NSWindowController alloc]initWithWindowNibName:#"MyNewWindowController"];
[wc showWindow:nil];
This displays the window. Now I want to reference that window in the new window controller but can't work out how. Specifically I have a button on the new window and I want to write something like:
- (IBAction)doStuffAndCloseWindow:(id)sender
{
[self doSomeStuff];
[*window* orderOut:nil];
}
I've tried creating a window variable (like the one created in appdelegate) but the compiler says my window variable is private.
So have do I declare and reference a window in my MyNewWindowController.m?
Thanks

Answer 1

That would be the 'window' method of NSWindowController. It's also a property that you can access via ".window".
So, in the first code snippet, that would be:
[wc window]
and in the second code snippet (assuming "doStuffAndCloseWindow" is part of your subclassed NSWindowController):
- (IBAction)doStuffAndCloseWindow:(id)sender
{
[self doSomeStuff];
[[self window] orderOut:nil];
}

Thanks to Michael, see above, first declare your subclassed NSwindowController thus
#property IBOutlet MyNewWindowController *wc;
Then in the implementation of the subclassed window controller, you can refer to the associated window with
[[self window] .....];
For example
[[self window] orderOut:self];
