about EventDispatcher

Guru
Is the EventDispatcher avaiable in the listener function currently? not passed as data.
EventDispatcher:addEventListener(type, listener, data)
for example, when handle mutiple events in one function,it's better to get who dispatch that event.

OR do you mean, what type of event was dispatched? e:getType()
I thought getTarget() return the listener function according to the reference manual.
It says "The target of an event is a listener function and an optional data value".
https://sites.google.com/site/xraystudiogame
local button = Button.new(up, down)
-- register to "click" event
local click = 0
print(button)
function listener(event)
print(event:getTarget())
click = click + 1
label:setText("Clicked " .. click .. " time(s)")
end
print(listener)
button:addEventListener("click", listener
)
And output:
table: 03399600
function: 0339A4B8
table: 03399600
event:getTarget() return the button, not the listener function.
