I have a window contained in a nib file that gets loaded by a custom subclass of `NSWindowController` like this:

```
- (id)init
{
    self = [super initWithWindowNibName:@"MyWindow"];

    return self;
}

```

I'd like to initialize the views in this window before it becomes visible. Right now I'm reading some User Defaults and setting the window's views in `windowDidLoad`. But unfortunately, the newly initialized values are applied only after the window has become visible, resulting in the uninitialized values flashing very briefly.

`windowWillLoad` doesn't work as the window has not been loaded from the nib file yet at that point.

How can I initialize the window before it is displayed?
