Mouse Touch event cross compatibility

ar2rsawseen

Hello,
does any one know a better solution of Mouse/Touch event cross compatibility.

Basically what I want to do is to make Mouse events behave as single touch event. So I can test my app both on Desktop (with mouse) and on Device (with multi touch support).

For now all I do is adding something similar to every event handler:

if e.x and e.y then e.touch = {} e.touch.id = 1 e.touch.x = e.x e.touch.y = e.y end

And I can use same event handlers for both functions and test on both platforms. But I need to modify every event handler with this code and need to add same handlers for both events. Which is bad, because on device both methods are called and of course it is a lot of work to do, especially when you have many different elements.

So maybe anyone knows a better way?

Or maybe event cross compatibility someday would be supported by Gideros?

Hi,

One possibility can be redefining EventDispather:addEventListener on Windows and Mac OS. I just get your approach and move it one step forward:

local os = application:getDeviceInfo()   if os == "Windows" or os == "Mac OS" then EventDispatcher.__addEventListener = EventDispatcher.addEventListener   local function wrapper(t, e) e.touch = {} e.touch.id = 1 e.touch.x = e.x e.touch.y = e.y   if t.data then t.listener(t.data, e) else t.listener(e) end end   function EventDispatcher:addEventListener(type, listener, data) if type == Event.TOUCHES_BEGIN then self:__addEventListener(Event.MOUSE_DOWN, wrapper, {listener = listener, data = data}) elseif type == Event.TOUCHES_MOVE then self:__addEventListener(Event.MOUSE_MOVE, wrapper, {listener = listener, data = data}) elseif type == Event.TOUCHES_END then self:__addEventListener(Event.MOUSE_UP, wrapper, {listener = listener, data = data}) else self:__addEventListener(type, listener, data) end end end     local function onTouchesBegin(e) print("begin", e.touch.id, e.touch.x, e.touch.y) end   local function onTouchesMove(e) print("move", e.touch.id, e.touch.x, e.touch.y) end   local function onTouchesEnd(e) print("end", e.touch.id, e.touch.x, e.touch.y) end   stage:addEventListener(Event.TOUCHES_BEGIN, onTouchesBegin) stage:addEventListener(Event.TOUCHES_MOVE, onTouchesMove) stage:addEventListener(Event.TOUCHES_END, onTouchesEnd)

Yes this issue is always on my mind

Is this means we will get this feature in next release?

And we do not need to add mouse events any more?

Can we get an update on this topic?
