pointerId property

  • Article

The unique identifier of the contact for a touch, mouse or pen.

This property is read-only.

 

Syntax

HRESULT get_pointerId(
  [out] long *lID
);

Property values

Type: long

Remarks

This remains the same throughout the lifetime of the pointer. The pointerID is used to associate an MSGesture object with a contact on an element so the element can receive MSGestureEvents.

Examples

//  Adds a pointer to the MSGesture object for the red square
function redListener(evt)
{
    if (evt.type == "pointerdown")
    {
        redGesture.addPointer(evt.pointerId);
        return;
    }
    printEvent(evt);
}
