@dr1rrb @carldebilly I think we can't support KeyDown for arbitrary controls on iOS, right ? Only on TextBox ?

carldebilly commented 3 years ago

Was talking with @MartinZikmund today specifically about this... and it seems he found a way to have them.

MartinZikmund commented 3 years ago

@jeromelaban at least for the hardware keyboard, I tested with iPad, and was able to capture key events at the root view controller level. Seems to be a 13.4+ feature - https://www.swiftbysundell.com/tips/handling-keyup-and-keydown-events/. But all iOS users update immediately anyway, so definitely seems worth adding!

In case of Android, we could also capture keyboard events at the activity level. Even though it does not include soft keyboard presses as Carl mentioned, the keyboard events are still most useful for hardware keyboard anyway. And it would open doors for things like keyboard shortcuts and whatnot

Anyway I suspect those events on iOS won't work when coming from a software on-screen keyboard neither...

@carldebilly quite possible, but still better then no support 👍 . I would say most scenarios where KeyDown handling (outside of TextBox) is needed, will be most relevant for hardware keyboard anyway.

Removed from blocker, because design was changed back to previous iteration
