What specific problem do we really need to solve... i.e. Is card-level
swiping generally important enough to warrant an approach which isn't
quite so general (very specific, one might say!)?
The thing here is that we could well consider adding a mechanism which
is *card* specific (rather than in full generality). e.g. We add a card
property which states in which directions a card could be swiped, and it
uses the standard delays, actions of swiping in the various directions.
Perhaps you get a swipeBegin message when the swipe starts (where you go
card or whatever - and a snapshot is taken after - i.e. an implicit lock
for visual effect); and then a swipeEnd / swipeCancel when it is done.
This would be a very high-level bit of functionality, not that
configurable.
Thinking about this some more...I'll take whatever we can get. But
thinking about real-world usage, on Android swiping is very commonly
used to pull out the sidebar, something almost every Android app has.
While iOS doesn't indulge in sidebars officially, they are so handy that
I understand the hamburger menu is being used by iOS developers too
(Apple frowns on it but looks the other way.)
Since it's possible to get a snapshot of a group that isn't currently
visible, and since sidebars are commonly LC groups, would that be
something also easily implemented?
In terms of yak-shaving, I wonder if same-card swipes might even be
easier to implement than navigation? This type of swipe could be used to
swipe away lines in lists (provided each line was its own control as per
datagrids,) or expose controls "under" list items, and so forth. Right
now there are no visual effects that accurately display this kind of
animation. I've been struggling to fake an Android toast and have sort
of made it work by animating within a rectangle, but it isn't perfect
and requires a very specific card layout to maintain the illusion.
But since I don't know what has to happen under the hood, I'll be happy
with card navigation if that's a better place to begin.
