* Custom gestures
* ==============================
*
* Gesture object
* --------------------
* The object structure of a gesture:
*
* { name: 'mygesture',
* index: 1337,
* defaults: {
* mygesture_option: true
* }
* handler: function(type, ev, inst) {
* // trigger gesture event
* inst.trigger(this.name, ev);
* }
* }
* @param {String} name
* this should be the name of the gesture, lowercase
* it is also being used to disable/enable the gesture per instance config.
*
* @param {Number} [index=1000]
* the index of the gesture, where it is going to be in the stack of gestures detection
* like when you build an gesture that depends on the drag gesture, it is a good
* idea to place it after the index of the drag gesture.
*
* @param {Object} [defaults={}]
* the default settings of the gesture. these are added to the instance settings,
* and can be overruled per instance. you can also add the name of the gesture,
* but this is also added by default (and set to true).
*
* @param {Function} handler
* this handles the gesture detection of your custom gesture and receives the
* following arguments:
*
* @param {Object} eventData
* event data containing the following properties:
* timeStamp {Number} time the event occurred
* target {HTMLElement} target element
* touches {Array} touches (fingers, pointers, mouse) on the screen
* pointerType {String} kind of pointer that was used. matches ionic.Gestures.POINTER_MOUSE|TOUCH
* center {Object} center position of the touches. contains pageX and pageY
* deltaTime {Number} the total time of the touches in the screen
* deltaX {Number} the delta on x axis we haved moved
* deltaY {Number} the delta on y axis we haved moved
* velocityX {Number} the velocity on the x
* velocityY {Number} the velocity on y
* angle {Number} the angle we are moving
* direction {String} the direction we are moving. matches ionic.Gestures.DIRECTION_UP|DOWN|LEFT|RIGHT
* distance {Number} the distance we haved moved
* scale {Number} scaling of the touches, needs 2 touches
* rotation {Number} rotation of the touches, needs 2 touches *
* eventType {String} matches ionic.Gestures.EVENT_START|MOVE|END
* srcEvent {Object} the source event, like TouchStart or MouseDown *
* startEvent {Object} contains the same properties as above,
* but from the first touch. this is used to calculate
* distances, deltaTime, scaling etc
*
* @param {ionic.Gestures.Instance} inst
* the instance we are doing the detection for. you can get the options from
* the inst.options object and trigger the gesture event by calling inst.trigger
*
*
* Handle gestures
* --------------------
* inside the handler you can get/set ionic.Gestures.detectionic.current. This is the current
* detection sessionic. It has the following properties
* @param {String} name
* contains the name of the gesture we have detected. it has not a real function,
* only to check in other gestures if something is detected.
* like in the drag gesture we set it to 'drag' and in the swipe gesture we can
* check if the current gesture is 'drag' by accessing ionic.Gestures.detectionic.current.name
*
* @readonly
* @param {ionic.Gestures.Instance} inst
* the instance we do the detection for
*
* @readonly
* @param {Object} startEvent
* contains the properties of the first gesture detection in this sessionic.
* Used for calculations about timing, distance, etc.
*
* @readonly
* @param {Object} lastEvent
* contains all the properties of the last gesture detect in this sessionic.
*
* after the gesture detection session has been completed (user has released the screen)
* the ionic.Gestures.detectionic.current object is copied into ionic.Gestures.detectionic.previous,
* this is usefull for gestures like doubletap, where you need to know if the
* previous gesture was a tap
*
* options that have been set by the instance can be received by calling inst.options
*
* You can trigger a gesture event by calling inst.trigger("mygesture", event).
* The first param is the name of your gesture, the second the event argument
*
*
* Register gestures
* --------------------
* When an gesture is added to the ionic.Gestures.gestures object, it is auto registered
* at the setup of the first ionic.Gestures instance. You can also call ionic.Gestures.detectionic.register
* manually and pass your gesture object as a param
*
