=== Number of touch points === | |||
Some uses of touch events may need to track various points at once. This can be handled by observing MozTouchDown/Release, but a field with the current number of touch points could be added to simplify things | |||
=== Size and pressure === | |||
Touch input also may provide detailed information about the contact area or pressure, but it depends on the platform and type of screen. We already have MozPressure attribute on MouseEvent, which is currently only used in some gtk. code. Win7 provides width and height of contact area. | Touch input also may provide detailed information about the contact area or pressure, but it depends on the platform and type of screen.
