Text input doesn't bring up virtual keyboard on mobile

[stmdhms]

This was recently fixed in egui itself (emilk/egui#247), but doesn't currently work correctly in bevy_egui.

[vihdzp]

This would be solved by #27.

I'm afraid just upgrading to 0.12 doesn't fix it. I guess we need to port the changes that were done in emilk/egui#253 to bevy_egui. Unfortunately, I'm not able to look into those myself atm, but I'm happy to accept a PR if anyone wants to tackle that.

Is it still possible to bring up the mobile keyboard with a WASM build?

[vladbat00]

Still impossible, unfortunately. If anyone wants to make a PR for this, I'll gladly accept it.

Hello, Ive been working on this on this branch (which also containts the work from #180 ). Due to winit lacking support for composition events in the web (as can be seen here) I excluded the event listeners for them as it currently sends them all out at once when the composition ends which causes unwanted behavior.

I can create a pull request once #180 is done

@oscrim did your code fix mobile keyboard issues with bevy_egui? I wasn't sure if this was an IME issue that has to be explored at a lower level.

[oscrim]

It was more of a work around than a proper fix. It's been a while since I looked at it

[v-kat]

Do you think it's something you could eventually upstream? I was still trying to understand if there was a bug in IME somewhere or if some of the code from egui needed to be adapted/bridged to bevy. (Maybe from https://github.com/emilk/egui/blob/master/crates/eframe/src/web/text_agent.rs )

I'm also curious about @Vrixyz opinion.

I might just steal your code and maybe try to upstream it >.> @oscrim

@v-kat please do!

I don't think the ime not working is a bug, if I interpret the docs correctly there is no ime support on android/ios/web in bevy or winit

https://docs.rs/winit/latest/winit/event/enum.WindowEvent.html#variant.Ime

Implemented in bevy_egui 0.30
