Re: no topLevelObjects in .gorm file?

[H. Nikolaus Schaller]

Hi,
there may be a completely different approach:

- add an IBOutlet (e.g. called mainWindow) to your NSDocument for your NSWindow 
and connect it.
- then you get a pointer mainWindow that can be accessed in -awakeFromNib; for 
your makeKeyAndOrderFront:

This avoids scanning the top level objects.

Hope this helps,
Nikolaus
