Encapsulation is a good thing. The events themselves should hold all the
data you need about the action as Ben said above. If you create new custom
events you should make sure they have storage for all the properties any
listener would need to know about what triggered the event, etc. If there's
really something you need that isn't in the event you can make it a class
variable and have access to it from the handler, stuff like state variables
is a good example since you may be in a state where you don't need to take
any action.
