BTW. the book is mine as well as Lykurg's.
Yes, sorry - I should have given him credit too.

So is the book worth getting, even for someone with experience? I doesn't sound like it is really about game development, even though that is the title. It seems more general than that.

But what I would really like is a comprehensive book on Qt Quick and QML - one with something more substantial than toy examples. Any recommendations there?
