Hey Boisy,

    In your VirtualDriveController.h you'll need:

IBOutlet NSView *virtualDriveView;

  Drag VirtualDriveController.h into the instances pane in Interface
Builder - that lets IB know all about your controller class - even
though you're not actually going to make an instance of it.

    Select the File's Owner in IB and open the inspector to Custom
Class ( Apple-5 I think, not in front of a Mac right now. ) From the
list of classes displayed select VirtualDriveController.

    Now you can drag a line from your File's Owner to the view and
connect it to vritualDriveView.

    When you call [NSBundle loadNibNamed: @"VirtualDriveView" owner:
self] the bundle loading code will connect your controllers
virtualDriveView instance variable to the view you tied it to in IB.
File's Owner is a stand in for the owner: argument in the call above.

    I'm not really sure why Stephane suggests not initing the
controller. I think that's just what he does in his code. The only
reason I can think of is that you may (well, will) get two
awakeFromNib: calls. One when your VirutalDriveController awakes from
the nib it's stored in and another when it loads it's Nib and
awakeFromNib gets called on File's Owner ( it's a proxy remember ).
Anyway if you know that it should be easy enough to deal with.

Hope that helps,
Guy
