how manage tap event BEFORE touch event on a display object

[oromanetti]

Hi,
My problem is about how manage tap event BEFORE touch event on a display object.
As you may know, listening to one display object for both touch and tap events will fire the touch event phases BEFORE the tap event fires.

The context

• I have a display object
• I can drag and drop this object : I use touch event for this with began / move / end phases. Classic stuff. At the end phase, when the object is dropped, a sound is played, and some actions occurs.
• I can double taped this object : different actions occurs when I double tapped.

What I’d like to do :
I would like NOT execute the code in my touch listener begin/move/end phases WHEN I double tapped the object.

Any help or idea would be appreciate
Thanks
Sincerely,

According to this page:
http://coronageek.com/1162/handling-corona-sdk-tap-events-vs-touch-events/

The tap and touch events are two different events, and the touch events get processed first.

You could try to write your touch handler so that a brief touch is interpreted as tap, and a longer touch would then be a touch. That way you do not have to worry about watching for a tap event. You would need to set up a time, and check how long the touch occurred in the ended phase.

Here is an example:

[lua]
local handleButtonTouch
local tapTimer
local newButton
local clock = os.clock

local function main()
newButton = display.newImage(“button.png”)
newButton.name =“button”
newButton.touch = handleButtonTouch
newButton:addEventListener(“touch”, newButton)
end

function handleButtonTouch(self, event)

if event.phase == “began” then

tapTimer = clock()

– specify the global touch focus
display.getCurrentStage():setFocus( self )
self.isFocus = true

elseif self.isFocus then
if event.phase == “moved” then

– do something here; or not
newButton.x = event.x
newButton.y = event.y

elseif event.phase == “ended” or event.phase == “cancelled” then

– reset global touch focus
display.getCurrentStage():setFocus( nil )
self.isFocus = nil

if clock()-tapTimer <= .5 then
print(“tap”)
else
print(“Touch”)
end

end
end
return true
end

main()
