Hi all,

hope it is not wrong to post a question here.

I have a problem with touch events when emulated via the Chrome Emulation. I have a simple Canvas with an added Touch Handler:

     final Canvas ca=Canvas.createIfSupported();
    ca.setCoordinateSpaceWidth(wiCo);
    ca.setCoordinateSpaceHeight(wiHe);
//    ca.sinkEvents(Event.TOUCHEVENTS);
    ca.sinkEvents(Event.ONTOUCHSTART);    




    ca.addTouchStartHandler(new TouchStartHandler() {
 @Override
 public void onTouchStart(TouchStartEvent event) {
 // TODO Auto-generated method stub
 Touch t=event.getTargetTouches().get(0);
 ca.getContext2d().setStrokeStyle("#fff");
 ca.getContext2d().clearRect(0, 0, 800, 200);
 ca.getContext2d().setStrokeStyle("#000");
 ca.getContext2d().strokeText("Move "+(t.getPageX()-ca.getAbsoluteLeft())+","+(t.getPageY()-ca.getAbsoluteTop()),10,60);
 consoleLog("Touch move ");
 }
 });

It works perfect on my Nexus7 but it doesnt work on my chrome when emulating Nexus7 and touches. Other Touch web apps (nativ JavaScript ? ) work in Emulation mode. But my (working) GWT app doesnt react to the (emulated) touch events. :(

Any experiences with it?

Many thanks in advance
