/**
|
|
* The nsIDOMSimpleGestureEvent interface is the datatype for all
|
|
* Mozilla-specific simple gesture events in the Document Object Model.
|
|
*
|
|
* The following events are generated:
|
|
*
|
|
* MozSwipeGesture - Generated when the user completes a swipe across
|
|
* across the input device.
|
|
*
|
|
* MozMagnifyGestureStart - Generated when the user begins the magnify
|
|
* ("pinch") gesture. The "delta" value represents the initial
|
|
* movement.
|
|
*
|
|
* MozMagnifyGestureUpdate - Generated periodically while the user is
|
|
* continuing the magnify ("pinch") gesture. The "delta" value
|
|
* represents the movement since the last MozMagnifyGestureStart or
|
|
* MozMagnifyGestureUpdate event.
|
|
*
|
|
* MozMagnifyGesture - Generated when the user has completed the
|
|
* magnify ("pinch") gesture. If you only want to receive a single
|
|
* event when the magnify gesture is complete, you only need to hook
|
|
* this event and can safely ignore the MozMagnifyGestureStart and the
|
|
* MozMagnifyGestureUpdate events. The "delta" value is the cumulative
|
|
* amount represented by the user's gesture.
|
|
*
|
|
* MozRotateGestureStart - Generated when the user begins the rotation
|
|
* gesture. The "delta" value represents the initial rotation.
|
|
*
|
|
* MozRotateGestureUpdate - Generated periodically while the user is
|
|
* continuing the rotation gesture. The "delta" value represents the
|
|
* rotation since the last MozRotateGestureStart or
|
|
* MozRotateGestureUpdate event.
|
|
*
|
|
* MozRotateGesture - Generated when the user has completed the
|
|
* rotation gesture. If you only want to receive a single event when
|
|
* the rotation gesture is complete, you only need to hook this event
|
|
* and can safely ignore the MozRotateGestureStart and the
|
|
* MozRotateGestureUpdate events. The "delta" value is the cumulative
|
|
* amount of rotation represented by the user's gesture.
|
|
*
|
|
* MozTapGesture - Generated when the user executes a two finger
|
|
* tap gesture on the input device. Client coordinates contain the
|
|
* center point of the tap.
|
|
* (XXX Not implemented on Mac)
|
|
*
|
|
* MozPressTapGesture - Generated when the user executes a press
|
|
* and tap two finger gesture (first finger down, second finger down,
|
|
* second finger up, first finger up) on the input device.
|
|
* Client coordinates contain the center pivot point of the action.
|
|
* (XXX Not implemented on Mac)
|
|
*
|
|
* Default behavior:
|
|
*
|
|
* Some operating systems support default behaviors for gesture events
|
|
* when they are not handled by the application. Consumers should
|
|
* use event.preventDefault() to prevent default behavior when
|
|
* consuming events.
