[SOLVED]Need help to find a gesture tutorial

Do anyone have a tutorial link for Multitouch gesture?
I am trying on my own but I am blocked, I just know about Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT
I would like to have some basic knowledge for Multitouch.inputMode = MultitouchInputMode.GESTURE
and which Event to call??? because apparently TouchEvent won’t work, and I would need a GestureEvent o.O??
FYI: my target is Android

Gestures are not supported, though there are libraries (“gestouch”?) which can help evaluate events to detect a gesture.

I used to handle swipe gestures, for example, by tracking a MOUSE_DOWN, then a MOUSE_UP, and if it occurred fast enough, and was more in the horizontal direction than vertical, and was more than a minimum distance away, then it would trigger a swipe

thanks very much I was also thinking of using something like

var pos:Float;
function onDown(e:MouseEvent){
pos = e.stageX;
function onUp(e:MouseEvent){
if(pos>e.stageX) trace(“swipe to the left”);
else if(pos<e.stageX) trace(“swipe to the right”);
else trace(“no swipe occured”);

but I never really thought of that small but important detail “fast enough”.
