I don't think there are any. Using a library is pretty much the same no matter which one you use. Once you get used to it, the documentation really is enough. The rest comes from experimenting. If you can find simple projects that are open source to look at code, they help also. And just ask questions on the forum specific to what you are attempting to do, and make a habit out of reading the forum questions not related to your project. Start out with simple projects and it will all come together. A good c++ book is important to have, however.
