GestureEvent

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The GestureEvent is a proprietary interface specific to WebKit which gives information regarding multi-touch gestures. Events using this interface include gesturestart, gesturechange, and gestureend.

Instance properties

This interface also inherits properties of its parents, UIEvent and Event.

GestureEvent.rotation Read only Non-standard

Change in rotation (in degrees) since the event's beginning. Positive values indicate clockwise rotation; negative values indicate counterclockwise rotation. Initial value: 0.0.

GestureEvent.scale Read only Non-standard

Distance between two digits since the event's beginning. Expressed as a floating-point multiple of the initial distance between the digits at the beginning of the gesture. Values below 1.0 indicate an inward pinch (zoom out). Values above 1.0 indicate an outward unpinch (zoom in). Initial value: 1.0.

Instance methods

This interface also inherits methods of its parents, UIEvent and Event.
