The tangentialPressure
read-only property of the PointerEvent
interface represents the normalized tangential pressure of the pointer input (also known as barrel pressure or cylinder stress).
PointerEvent.tangentialPressure
Value
A float
representing the normalized tangential pressure of the pointer input in the range -1
to 1
, inclusive, where 0
is the neutral position of the control.
Note that some hardware may only support positive values in the range 0
to 1
. For hardware that does not support tangential pressure, the value will be 0
.
Examples
In this snippet, when a pointerdown
event is fired, different functions are called depending on the value of the event's tangentialPressure
property.
someElement.addEventListener('pointerdown', function(event) { if (event.tangentialPressure == 0) { // No pressure process_no_tanPressure(event); } else if (event.tangentialPressure == 1) { // Maximum pressure process_max_tanPressure(event); } else { // Default process_tanPressure(event); } }, false);
