PointerEvent.twist
The twist
read-only property of the
PointerEvent
interface represents the clockwise rotation of the pointer
(e.g., pen stylus) around its major axis, in degrees.
Syntax
var twist = pointerEvent.twist;
Return value
A long
value representing the amount of twist, in degrees, applied to the
transducer (pointer). The value is in the range 0
to 359
,
inclusive. For devices that do not report twist
, the value is
0
.
Example
When a pointerdown
event is fired, different functions are called
depending on the value of the event's twist
property.
someElement.addEventListener('pointerdown', function(event) {
if (event.twist == 0) {
// No twist
process_no_twist(event);
} else {
// Default
process_twist(event);
}
}, false);
