Error - Can getTarget() from "click" but event.x returns nil. Any idea?

Mells

Hi community,

My code is - I believe - really basic and I don't see where the error comes from.
I have tried to isolate the part that raises an issue. Error could be located somewhere else but I have no idea where it could be :

function Interface:init() -- FB local fbButton fbButton = Button.new(Bitmap.new(...)) fbButton:addEventListener("click", self.onFbClick, self) stage:addChild(fbButton) fbButton.debugName = "bob" end

and

function Interface:onFbClick(event) local target = event:getTarget() print (target.debugName) -- prints "bob" correctly print (event.x, event.y) -- prints "nil, nil"   if target:hitTestPoint(event.x, event.y) then -- And then here the error happens -> bad argument #1 to 'hitTestPoint' (number expected, got nil) event:stopPropagation() print ("Fb sharing") end end

I don't understand why I can get the target from the event, but not event.x and event.y.

Has it ever happened to you and how did you solve it?

Hi Mells,

You want to get x,y coordinate of the place on the fbButton?
event:getTarget() return the button, not the listener function.

Try here, it should give you the information you want.

While Button class dispatches "click" event, it doesn't set event.x and event.y fields. And Button class already does the hitTestPoint check and stopPropagation. I think your function should be just:

function Interface:onFbClick(event) print ("Fb sharing") end

Thank you all
About the Button class -> Wow, I love it when Gideros already does the work for me (I should have checked the code more).

My mistakes :

1. I assumed that *all* click events come with event.x and event.y fields set
2. Lack of understanding of what the Button class is doing under the hood

So here is what I had to do :

function Interface:init() -- FB local fbButton fbButton = Button.new(...) stage:addChild(fbButton) fbButton:addEventListener("click", self.onFbClick) end   function Interface:onFbClick(event) print ("Fb sharing") end

Thank you community.
