Events vs Dispatching Events

OZApps · August 2012

Here's the sample code that I tried.

 -- Sample code to test this issue
local function onMouseUp(event)
  for i,j in pairs(event) do
    print(i,j)
  end 
end 
 
stage:addEventListener(Event.MOUSE_UP, onMouseUp)

Now it tells me that one of the members of the event is "type" and has the value of "mouseUp"

I tried to dispatch a mouseUp event as

 local evt = Event.new("mouseUp")  -- Even tried it as Event.new(Event.MOUSE_UP)
 for i,j in pairs(evt) do
  print(i,j)
 end 
 -- There is no "type", instead there is a "_type"
 -- so, tried to manually fix that too
 
 evt.type = "mouseUp"
 stage:dispatchEvent(evt)
 
 -- This does not work. Any ideas why?

Event.MOUSE_UP is a built in event. I doubt you can dispatch it.

In your case something like this would work:

 -- Sample code to test this issue
local function onMouseUp(event)
   print("mouseUp")
end 
 
stage:addEventListener("mouseUp", onMouseUp)
 
 local evt = Event.new("mouseUp")
 stage:dispatchEvent(evt)

@ar2rsawseen, A slight correction Event.MOUSE_UP is just a string "mouseUp"

For some reason the code

 -- Sample code to test this issue
local function onMouseUp(event)
   print("mouseUp")
end 
 
stage:addEventListener(Event.MOUSE_UP, onMouseUp)
 
 local evt = Event.new(Event.MOUSE_UP)
 stage:dispatchEvent(evt)

works, but when I am trying to dispatch it with the same, it doesn't. Maybe @Atilim could shed some light on this.

@DOH!! How silly of me, it works just as I expected it, the code I posted will work, the problem was that the handler was set on another object but triggered on the stage
