The nsIDOMMozTouchEvent interface describes a raw touch event. This provides a mechanism for working with events from touch screens. This differs from tracking mouse events in that touch events can be generated independently for each finger touching the screen. This lets you process multi-finger touch gestures and actions.

Attributes
| Attribute | Type | Description |
