defaults
|
default settings.
more settings are defined per gesture at /gestures. Each gesture can be disabled/enabled
by setting it’s name (like swipe) to false.
You can set the defaults for all instances by changing this object before creating an instance.

DOCUMENT
|
GestureDetector document where the base events are added at
|
|
HAS_POINTEREVENTS
|
detect support for pointer events
|
|
HAS_TOUCHEVENTS
|
detect support for touch events
|
|
IS_MOBILE
|
detect mobile browsers
|
|
NO_MOUSEEVENTS
|
detect if we want to support mouseevents at all
|
|
CALCULATE_INTERVAL
|
interval in which GestureDetector recalculates current velocity/direction/angle in ms
|
|
EVENT_TYPES
|
eventtypes per touchevent (start, move, end) are filled by Event.determineEventTypes on setup
the object contains the DOM event names per type (EVENT_START, EVENT_MOVE, EVENT_END)
|
|
DIRECTION_DOWN|LEFT|UP|RIGHT
|
direction strings, for safe comparisons
|
|
POINTER_MOUSE|TOUCH|PEN
|
pointertype strings, for safe comparisons
|
|
EVENT_START|MOVE|END|RELEASE|TOUCH
|
eventtypes
|
|
READY
|
if the window events are set…

prevent_mouseevents
|
when touch events have been fired, this is true
this is used to stop mouse events
|
|
started
|
if EVENT_START has been fired
|
|
should_detect

when the mouse is hold down, this is true
|
|

options
|
options, merged with the defaults
options with an _ are converted to camelCase
|
|
eventStartHandler
|
event start handler on the element to start the detection
|
|
eventHandlers
|
keep a list of user event handlers which needs to be removed when calling ‘dispose’
|
|
dragMinDistance
|
minimal movement that have to be made before the drag event gets triggered
|
|
dragDistanceCorrection
|
Set dragDistanceCorrection to true to make the starting point of the drag
be calculated from where the drag was triggered, not from where the touch started.
Useful to avoid a jerk-starting drag, which can make fine-adjustments
through dragging difficult, and be visually unappealing.
|
|
dragMaxTouches
|
set 0 for unlimited, but this can conflict with transform
|
|
dragBlockHorizontal
|
prevent default browser behavior when dragging occurs
be careful with it, it makes the element a blocking element
when you are using the drag gesture, it is a good practice to set this true
|
|
dragBlockVertical
|
same as dragBlockHorizontal, but for vertical movement
|
|
dragLockToAxis
|
dragLockToAxis keeps the drag gesture on the axis that it started on,
It disallows vertical directions if the initial direction was horizontal, and vice versa.
|
|
dragLockMinDistance
|
drag lock only kicks in when distance > dragLockMinDistance
This way, locking occurs only when the distance has become large enough to reliably determine the direction
|
|
holdTimeout

|
|
holdThreshold
|
movement allowed while holding
|
|
swipeMinTouches

|
|
swipeVelocityX
|
horizontal swipe velocity
|
|
swipeVelocityY
|
vertical swipe velocity
|
|
tapMaxTime
|
max time of a tap, this is for the slow tappers
|
|
tapMaxDistance
|
max distance of movement of a tap, this is for the slow tappers
|
|
tapAlways
|
always trigger the tap event, even while double-tapping
|
|
doubleTapDistance
|
max distance between two taps
|
|
doubleTapInterval
|
max time between two taps
|
|
preventDefault
|
call preventDefault at touchstart, and makes the element blocking by disabling the scrolling of the page,
but it improves gestures like transforming and dragging.
be careful with using this, it can be very annoying for users to be stuck on the page
|
|
preventMouse
|
disable mouse events, so only touch (or pen!) input triggers events
|
|
transformMinScale
|
minimal scale factor, no scale is 1, zoomin is to 0 and zoomout until higher then 1
|
|
transformMinRotation
|
rotation in degrees
