SwipeGestureRecognizer Properties

Allows simultaneous execution if the platform specific views do no match. Default is true.

Whether tracked touches are cleared when the gesture ends or fails, default is false. By setting to true, you allow the gesture to possibly execute again with a different touch even if the original touch it failed on is still on-going. This is a special case, so be sure to watch for problems if you set this to true, as leaving it false ensures the most correct behavior, especially with lots of gestures at once.

The current tracked touches for the gesture

Custom data for the gesture that you can attach, or just leave null if you don't need this This is useful if you want to retrieve this in a callback function, but it is not require for the gesture to work properly

Change in focus x in pixels

Change in focus y in pixels

The swipe direction required to recognize the gesture (default is any)

For set directions, this is the amount that the swipe must be proportionally in that direction vs the other direction. For example, a swipe down gesture will need to move in the y axis by this multiplier more versus moving along the x axis. Default is 1.5, which means the swipe down gesture needs to be 1.5 times greater in the y axis vs. the x axis. Less than or equal to 1 means any ratio is acceptable.

The distance (in pixels) the gesture focus has moved from where it started along the x axis

The distance (in pixels) the gesture focus has moved from where it started along the y axis

Whether the gesture is Enabled. Default is true.

The direction of the completed swipe gesture, will be Any if unknown

Controls how the swipe gesture ends - see SwipeGestureRecognizerEndMode for more details

Whether to fail if the gesture changes direction mid swipe

Focus x value in pixels (average of all touches)

Focus y value in pixels (average of all touches)

True if gesture is in process of restarting, false otherwise

The maximum number of touches to track. This gesture will never track more touches than this. Default is usually 1 or 2. Not all gestures will honor values higher than 1.

The minimum distance the swipe must travel to be recognized. Default is 1.

The minimum number of touches to track. This gesture will not start unless this many touches are tracked. Default is usually 1 or 2. Not all gestures will honor values higher than 1.

The minimum units per second the swipe must travel to be recognized. Default is 3.0.

A platform specific view object that this gesture can execute in, null if none

The platform specific view scale (default is 1.0). Change this if the view this gesture is attached to is being scaled.

Average pressure of all tracked touches

Previous focus x

Previous focus y

Whether additional touches were added to the gesture since the last execute state.

If this gesture reaches the EndPending state and the specified gestures fail, this gestures will end. If the specified gesture begins, executes or ends, then this gesture will immediately fail.

Convenience method to add / remove one gesture to require failure on. Set to null to clear all require gestures to fail.

Whether the gesture should reset when it ends

Whether to send begin and executing states. Default is true. If false, only possible, ended or failed state is sent.

The speed of the gesture in pixels using focus

Start focus x value in pixels (average of all touches)

Start focus y value in pixels (average of all touches)
