Excluding child window events

[Dr-Hex]

Hi,
I'm trying to subscribe create window event and exclude one emitted by children.
However, it seems the child windows is still generating events.
Can you suggest please, what is wrong here:

            var winEventObservable = WinEventHook.Create(
                Dapplo.Windows.Enums.WinEvents.EVENT_OBJECT_CREATE 
                ).Where(winEventInfo => 
                winEventInfo.IsSelf &&
                winEventInfo.ObjectIdentifier == Dapplo.Windows.User32.Enums.ObjectIdentifiers.Window
                )
                .Select(info => InteropWindowFactory.CreateFor(info.Handle).Fill())
                .Subscribe(interopWindow =>
                {
                    Console.WriteLine("Window created: {0}. Title = {1}", interopWindow.Handle, interopWindow.Caption);
                    replaySubject.OnNext(interopWindow);
                }, exception => Console.WriteLine("An error occured: {0}", exception));

Thank you for the nice project.

I read you question a few days ago, but I'm not 100% sure what you like to do.
Maybe the interpretation of "IsSelf" is not completely clear, and doesn't match your need.

I'm not sure what the "child" is in your case.

I love to hear a few more details!

Sorry for late reply.
Imagine that some process is started and displayed the "main" visible window (and perhaps, some hidden windows).
I'd like to receive "create" notifications from that "main" window (having no parent window).
For me, the mentioned code generate notification even by child controls as well.
