Hi all,

I'm using the following sample to hadle Pinch Zoom event.

protected boolean touchEvent(TouchEvent message) 
{
   switch(message.getEvent()) 
   {
      case TouchEvent.GESTURE:
         TouchGesture gesture = message.getGesture();
         switch(gesture.getEvent()) 
         {
           case TouchGesture.PINCH_END:
             Dialog.alert("Focal point: " + message.getX(1) 
             +            ", " + message.getY(1)
             +            "\nFinal zoom value: " + gesture.getPinchMagnitude());
             return true;
         }
   }
   return false;
}

But it's not woked for me. I put the break point and it never hit it. My app can not handle this event.

Someone can tell me why?

Is touchEvent being called at all, or just not your pinch code? Where are you overriding touchEvent? Do you have other fields on the screen that may be capturing the event?

Thank you!
I have just found the reason that I haven't enabled pinch gestures.
