Been away from my computer for the past week (WWDC). Glad to see that you seem to have solved your problem. I’ll be sure to address the issue of a non-document based application with the next update to the view controllers.

Thanks for sharing your solution and if you have more questions, don’t hesitate to send me an email.

I posted my solution back on the cocoa-dev list (june 14 2008 postings)
It required a bit of code in my AppController specifically

@interface AppController : NSObject {
IBOutlet NSWindowController *windowController;
NSViewController *viewController;
}

@implementation AppController
- (id)init
{
if ( self = [super init] )
{
// substitute yourView’s nib + controller names in next line
viewController = [[TheViewController alloc] initWithNibName:@”TheView” bundle:nil];
}
return self;
}

- (void)awakeFromNib
{
[viewController.view setFrame:[windowController.window.contentView frame]];
[windowController.window.contentView addSubview:viewController.view];
}
@end

plus adding an NSWindowController, putting both into the MainMenu.nib and connecting them there.

Then in TheView.xib I set the FileOwner to be TheViewController and connect its view in IB… and set up all the other widgets/connections.

That seems to work and can be copied/shared with other apps.

However.

My applications are not Document based. They are conventional Cocoa apps, which start life from the XCode 3.0 New Project Assistant->Application>Cocoa Application (and sometimes Cocoa-Python application). They start off with a Main Menu.nib which has a Window.

How do I make the XS view/window stuff work in this framework?
I tried moving the MyView files over, creating an AppController, removing the Window from MainMenu.xib, creating a MyWindow.xib + Controller, which loads MyView. The best I was able to get was MyView showing up, but pushing the button drops me into the debugger under [NSApplication sendAction:to:from:].

Apparently the NSApp isnt connected to the window?

WRT the auto/absolute/relative resizing, are you familiar with Layouts in Java? In that architecture a window/view has a Layout which defines how its subviews are laid out. There are absolute Layouts and relative ones that will automagicially wrap/clip subviews. It can be quite powerful … and frustrating.
