I would also recommend the SFML book ( if you are serious about learning SFML game development. In my opinion it is one of the best game development books for people that learn through example. Though be warned you should have a good grasp of C++ and its features before reading it.
The authors of the book are very knowledgeable of the SFML library (One of them is the created of Thor which is a popular extension people use with SFML). They also made it a point to use up to date C++11 code whenever it was possible which was refreshing to say the least. You can tell they put a lot of effort into making it.
Some subjects they will teach you about are
~ Resource Management
~ Managing the game loop and using a effective time step
~ User input
~ State Management (Loading Screens, Menus, Paused Screen, ect)
~ Simple GUI's for your games
~ Particle Systems
~ Shader Support (You also implement a simple shader)
~ Background Music and Sound Effects
~ Networking and Co-op play
~ Event handling (I love their event system in the book)
That is just to name a few broad topics. Each of them has many sub topics that they cover very well. Here is the table of contents http://www.packtpub.com/sfml-game-development/book
If you are serious about learning SFML and have a good understanding of C++ then the best resource available for learning to use it would be this book. In my opinion nothing else really comes close.
Anyways wish you the best of luck and if you have any questions on any problems you have with SFML development feel free to post them in this forum.
