title: GWT Custom Events
body: <p>Hey I have a problem getting my head around how custom GWT event Handlers work. I have read quite a bit about the topic and it still is some what foggy. I have read threads here on Stackoverflow like this one <a href="https://stackoverflow.com/questions/998621/gwt-custom-event-handler">GWT Custom Event Handler</a>. Could someone explain it in an applied mannar such as the following.</p>
  
  <p>I have 2 classes a block and a man class. When the man collides with the block the man fires an event ( onCollision() ) and then the block class listens for that event.</p>
  
  <p>Thanks</p>
