Im still having problems with this. When I try to read the port I get a message
that there is no output named "myportname"
I tried to register for a notification with
- (void) QCViewDidStartRenderingNotification:(NSNotification*)notification
{
NSLog(@"QCViewDidStartRenderingNotification");
}
but I never get the notification. I also attempted to read the port inside
if ([visView isRendering]) {
groupArray = [visView valueForOutputKey:@"groupList" ofType:
@"NSArray"];
but it throws an exception. So I think the composition is rendering but the
port is just not available yet. How can I test for the availability of a port
in a qcView?
