[Interest] emitting signals from UIApplication app delegate?

[Jason H]

I want a QObject class to emit a signal when a function in my app delegate is 
invoked. (Code follows) How can I do that? I don't know how to use QObjects in 
ObjectiveC

--- PlatformShimImpl.cpp
PlatformShimImpl::PlatformShimImpl(){
        qDebug() << Q_FUNC_INFO;
        QtAppDelegate *appDelegate = (QtAppDelegate *)[[UIApplication 
sharedApplication] delegate];
        [[UIApplication sharedApplication] setDelegate:[QtAppDelegate 
sharedQtAppDelegate]];
        //[[QtAppDelegate sharedQtAppDelegate] setWindow:appDelegate.window];
}


--- QtAppDelegate.mm
- (void)applicationWillResignActive:(UIApplication *)application
{
        [application setIdleTimerDisabled:NO];
        // emit resignActive()
}


Many thanks.
