           Summary: Touch Events arbitrary exposed on Desktop version of
                    Qtwebkit
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Major
          Priority: P2
         Component: WebCore JavaScript
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: cedric at infonais.fr


Since Qt4.6 (as far as I could read) Webcore is exposing touch events even if the device isn't a touch device.

It's is missleading javascript application to think they are on a touch device and disable standard events handler.

to reproduce the problem try to load the HelloWorld sample : http://code.google.com/intl/fr-FR/apis/maps/documentation/javascript/examples/map-simple.html
into a qwebview

the map will load with the mobile UI no mouse drag (pan) no mousewheel (zoom)

this is caused by a test made by the google api.

function gk(a,b){
var c=n[tb]("div");c[x](b,"return;");
return typeof c[b]=="function"||b in n[ji]
};

we have 
 var n = document;
 var tb = "createElement";
 var x = "setAttribute";
 var ji = "documentElement";

gk(qk,"ontouchstart"); // will always return true on Qtwebkit

the function create a div element assign "return;" to the ontouchstart event and check if the type of the returned object is function

it also check the property "ontouchstart" of document.documentElement 


it should be possible to not expose the touchevents (ontouchstart,ontouchmove,ontouchend) within the application

something like QWebSettings::globalSettings()->setAttribute(QWebSettings::TouchEnabled,true/false);


I guess not only google api is impacted other big JS libraries like Jquery/JQueryMobile/Modernizr should also be affected.
