title: what is correct ActionListener structure?
body: <p>I'm still a student and I'm not sure what is correct structure for an ActionListener ? is it completely ok to just leave them in the layout constructor ? I don't want to train myself bad habits this early on...</p>
  
  <p>to clarify I'm using google's web toolkit which creates action listeners by default in the constructor however prior to that I used ActionListenerHandler (which is sorta a constructor by itself)</p>
