Correct way to detect swipes

[krister viirsaar]

I had assumed detecting swipes would be easy. I found no documentation on this so I'm asking what is the correct way to detect swipes?
By Swiping I mean http://youtu.be/WZswKaYSkSo?t=14s
I need to integrate swipe into ScreenManager. Carousel is too simple.

I've found two methods, I'll call them Complex and Overkill:
1. Complex: Rip it from (for example) the Carousel widget, through these functions:

    def _get_uid(self, prefix='sv'):
    def on_touch_down(self, touch):
    def on_touch_move(self, touch):
    def on_touch_up(self, touch):
    def _do_touch_up(self, touch, *largs):

2. Overkill: Use Gesture recognition from http://kivy.org/docs/api-kivy.gesture.html

---
Extra: It would be awesome if the Screen transition would start during swipe, not after. Just like in Carousel.

While I dont share his tone, I agree with his main idea.

Is there a way to simply do swipes yet?

Im mainly afraid of having to setup an hypothetical swype in _all_ my widgets. 

Since there are layers over layers of layouts in my app, would there be a way for _any_ widget or layout to detect a swipe, or would I have to bind it to all the widgets in the app?

Thank you.

Bumping this.  Newbie here, and came searching for this topic.

I have a simple working version of this that did just keeping track of touch_up and touch_down, but was wondering if there is a more standardized (or already implemented) way of doing this in kivy?  Is this something that would be best implemented as a "behavior?"

Probably we would be happy to accept a SwipeBehavior. It wouldn't be very hard to code.

I think the main reason it's lacking is that nobody has both needed and implemented it, not that there's a major problem with it.

Thanks for the info.  If I figure out the right way to do this, I will post here!

Any updates? :D

Same question here! Does kivy have any handler for swipes?

Looks like right to left swiping works pretty well. I'm not sure what I would have to do to implement left to right, but it's a start.
