This tutorial is provided to give you the basis to be able to use the so good PixLib framework made by Francis Bourre. You should know at least what is a MVC pattern and a Command pattern.

Usually, using a MVC, each view will have a controller that will update the model ( if needed ) and any views that need to be changed.
This can be achieved in the PixLib library using the class in com.bourre.mvc. But this tutorial will not deal with this “usual” MVC pattern.

Francis add to his framework something really flexible, called the FrontController. This controller is receiving events from any views and then call the Command associated to it.
You’re code is then really clean and pratical: one class = one command so your code for an action can be found really easilly, plus you can see all the actions that could be executed looking at the FrontController code, everything is in there.
You will not look in X classes to try to find the code that do this particular action, you will go straight to the goal.
