iChat Theatre

[Mark Alldritt]

Hi Folks,

I've been trying to get a simple demo app running that uses iChat  
Theatre (InstantMessage.framework) as described in this web page  
without any success:

  http://developer.apple.com/leopard/overview/imframework.html

Here's the code:

//
//  MyController.m
//  iChatDemo

#import "MyController.h"
#import <InstantMessage/IMAVManager.h>
#import <InstantMessage/IMService.h>

@implementation MyController

- (void) _handleStateChanged:(NSNotification*) notification
{
        NSLog(@"_handleStateChanged: %@", notification);

        IMAVManager *manager = [IMAVManager sharedAVManager];

        switch ([manager state])
        {
        case IMAVRequested:
                [manager start];
                break;
        }
}

- (void) _handleURLToShareChanged:(NSNotification*) notification
{
	NSLog(@"_handleURLToShareChanged: %@ (%@)", notification,  
[[IMAVManager sharedAVManager] URLToShare]);
}

- (void) awakeFromNib
{
        IMAVManager *manager = [IMAVManager sharedAVManager];
        [manager setVideoDataSource:miChatView];

        //      Register for iChat Theater notifications
        [[IMService notificationCenter] addObserver:self
                                        selector:@selector(_handleStateChanged:)
                                        name:IMAVManagerStateChangedNotification
                                        object:nil];
        [[IMService notificationCenter] addObserver:self
                                        
selector:@selector(_handleURLToShareChanged:)
                                        
name:IMAVManagerURLToShareChangedNotification
                                        object:nil];
}

@end


miChatView is an NSImageView displaying a picture that I want to show  
through iChat Theatre.  I never receive  
IMAVManagerStateChangedNotification notifications when I try and share  
my application file through the iChat app.  My demo project is based  
on the Cocoa Application template, so there is no notion of a document.

Can anyone tell me what I might be doing wrong?

Thanks
-Mark
