Hi Ralph,

The way it works can be really simple (other ways available but this one
fills perfectly my needs
) :

1.- the html/js side :

page1.html need to include some javascript :

simple iOS/Android working example :

> 	<script type="text/javascript">
> 		var priogesture = 1, start_x = 0, stop_x = 0, start_y = 0,
stop_y = 0;
> 		function $(id) { return document.getElementById(id); }
> 		$("swipe-wrap").addEventListener ("touchstart", function
(event) { 
> 			start_x = event.touches[0].screenX; start_y =
event.touches[0].screenY; priogesture = 0;
> 		});
> 		$("swipe-wrap").addEventListener ("touchmove", function
(event) {
> 			stop_x = event.touches[0].screenX; stop_y =
event.touches[0].screenY;
> 			if ((priogesture == 0) && (stop_x != 0) &&
(Math.abs(stop_x - start_x) > Math.abs(stop_y - start_y))) { 
> 				if (start_x < stop_x) {
>
document.location.href="file:/data/data/com.pierresahores.alainweiz/cache/pr
ev.html";
> 				} else if (start_x > stop_x) {
>
document.location.href="file:/data/data/com.pierresahores.alainweiz/cache/ne
xt.html";
> 				}
> 			}
> 		});
> 	</script>


a.- able to handle the touch messages it receive from your mobile app users;
b.- and initiate a new pageN.html load;

2.- the livecode scripting side :

> on browserLoadRequested pUrl, pType
>    if the platform is "iPhone" then
>       if "/cache/prev.html" is in pURL then 

your iOS dedicated LC code comes there

> on browserStartedLoading pUrl
>    if "/cache/prev.html" is in pURL and the platform is "android" then

your Android dedicated LC code comes there

Best,

Pierre

even possible on mobile? I have a html local page with a map image. I would
like to call an LC procedure with a parameter when the user presses within a
specific county on the page.
