# Objective - Update winit dependency to 0.29 ## Changelog ### KeyCode changes - Removed `ScanCode`, as it was [replaced by KeyCode](https://github.com/rust-windowing/winit/blob/master/CHANGELOG.md#0292). - `ReceivedCharacter.char` is now a `SmolStr`, [relevant doc](https://docs.rs/winit/latest/winit/event/struct.KeyEvent.html#structfield.text). - Changed most `KeyCode` values, and added more. KeyCode has changed meaning. With this PR, it refers to physical position on keyboard rather than the printed letter on keyboard keys. In practice this means: - On QWERTY keyboard layouts, nothing changes - On any other keyboard layout, `KeyCode` no longer reflects the label on key. - This is "good". In bevy 0.12, when you used WASD for movement, users with non-QWERTY keyboards couldn't play your game! This was especially bad for non-latin keyboards. Now, WASD represents the physical keys. A French player will press the ZQSD keys, which are near each other, Kyrgyz players will use "Цфыв". - This is "bad" as well. You can't know in advance what the label of the key for input is. Your UI says "press WASD to move", even if in reality, they should be pressing "ZQSD" or "Цфыв". You also no longer can use `KeyCode` for text inputs. In any case, it was a pretty bad API for text input. You should use `ReceivedCharacter` now instead. ### Other changes - Use `web-time` rather than `instant` crate. (rust-windowing/winit#2836) - winit did split `run_return` in `run_onDemand` and `pump_events`, I did the same change in bevy_winit and used `pump_events`. - Removed `return_from_run` from `WinitSettings` as `winit::run` now returns on supported platforms. - I left the example "return_after_run" as I think it's still useful. - This winit change is done partly to allow to create a new window after quitting all windows: emilk/egui#1918 ; this PR doesn't address. - added `width` and `height` properties in the `canvas` from wasm example (#10702 (comment)) ## Known regressions (important follow ups?) - Provide an API for reacting when a specific key from current layout was released. - possible solutions: use winit::Key from winit::KeyEvent ; mapping between KeyCode and Key ; or . - We don't receive characters through alt+numpad (e.g. alt + 151 = "ù") anymore ; reproduced on winit example "ime". maybe related to rust-windowing/winit#2945 - (windows) Window content doesn't refresh at all when resizing. By reading rust-windowing/winit#2900 ; I suspect we should just fire a `window.request_redraw();` from `AboutToWait`, and handle actual redrawing within `RedrawRequested`. I'm not sure how to move all that code so I'd appreciate it to be a follow up. - (windows) unreleased winit fix for using set_control_flow in AboutToWait rust-windowing/winit#3215 ;⚠️ I'm not sure what the implications are, but that feels bad 🤔 ## Follow up I'd like to avoid bloating this PR, here are a few follow up tasks worthy of a separate PR, or new issue to track them once this PR is closed, as they would either complicate reviews, or at risk of being controversial: - remove CanvasParentResizePlugin (#10702 (comment)) - avoid mentionning explicitly winit in docs from bevy_window ? - NamedKey integration on bevy_input: rust-windowing/winit#3143 introduced a new NamedKey variant. I implemented it only on the converters but we'd benefit making the same changes to bevy_input. - Add more info in KeyboardInput #10702 (review) - #9905 added a workaround on a bug allegedly fixed by winit 0.29. We should check if it's still necessary. - update to raw_window_handle 0.6 - blocked by wgpu - Rename `KeyCode` to `PhysicalKeyCode` #10702 (comment) - remove `instant` dependency, [replaced by](rust-windowing/winit#2836) `web_time`), we'd need to update to : - fastrand >= 2.0 - [`async-executor`](https://github.com/smol-rs/async-executor) >= 1.7 - [`futures-lite`](https://github.com/smol-rs/futures-lite) >= 2.0 - Verify license, see [discussion](#8745 (comment)) - we might be missing a short notice or description of changes made - Consider using https://github.com/rust-windowing/cursor-icon directly rather than vendoring it in bevy. - investigate [this unwrap](#8745 (comment)) (`winit_window.canvas().unwrap();`) - Use more good things about winit's update - #10689 (comment) ## Migration Guide This PR should have one.

Hi, I'm having some issues with this: 2024-03-23.11-43-56.trimmed.mp4I've seen that closing the window while continuing program execution is supported, but for me, the window will freeze until either a new window is closed or the program exits. Any workarounds, or fixes? Thanks! |

* Closes emilk#1918 * Closes emilk#4437 * Closes emilk#4709 * [x] I have followed the instructions in the PR template Hiya, I need new winit for a specific fix for a android_native_actvity. There are already two PRs, but both don't seem to have a lot of movement, or are entirely complete: emilk#4466 Seems to have gone stale & is missing some bits. emilk#4702 Also seems stale (if less so), and is missing a refactor to run_on_demand. I also *think* the accesskit integration has a mistake and can't be enabled. I've marked them as a co-author on this as I started from this branch. (I think! Haven't done that on git before...). Sorry for the wall of text but just dumping some details / thoughts here: - There's an issue with creating child windows in winit 0.30.1 and up on macOS. The multiple_viewports, "create immediate viewport" example crashes on anything later 0.30.1, with a stack overflow in unsafe code. I've create [a winit issue](rust-windowing/winit#3800), it *might* already be fixed in 0.31.0 but I can't test as 0.31 will likely require another refactoring. For now I have just pinned things to 0.30.0 exatly. - Winit has deprecated run_on_demand, instead requiring the ApplicationHandler interface. In 0.31.0 run_on_demand is removed. I've refactored both the integration and the WinitApp trait to follow this pattern. I've left user_events a bit more opaque, as it seems 0.31.0 is doing a rework of UserEvents too. - I've used the new lazy init approach for access kit from this branch https://github.com/mwcampbell/egui/tree/accesskit-new-lazy-init and marked Matt as co-author, thanks Matt! - There was very similair but not quite the same code for run_and_return and run_and_exit. I've merged them, but looking at the github issues graveyard it seems vey finnicky. I *hope* this is more robust than before but it's a bit scary. - when receiving new_events this also used to check the redraw timing dictionary. That doesn't seem necesarry so left this out, but that is a slight behaviour change? - I have reeneabled serial_windows on macOS. I wondered whether it was fixed after this PR and does seem to be! However, even before this PR it seems to work, so maybe winit has sorted things out before that... Windows also works fine now without the extra hack. - I've done a very basic test of AccessKit on Windows and screen reader seems ok but I'm really not knowleadgable enough to say whether it's all good or not. - I've tested cargo tests & all examples on Windows & macOS, and ran a basic Android app. Still, testing native platforms is wel... hard so if anyone can test linux / iOs / older mac versions / windows 10 would probably be a good idea! - For consistencys sake I've made all event like functions in WinitApp return a `Result<EventResult>`. There's quite a bit of Ok-wrapping now, maybe too annoying? Not sure. Thank you for having a look! * [x] macOS * [x] Windows * [x] Wayland (thanks [SiebenCorgie](https://github.com/SiebenCorgie)) * [x] X11 (thanks [crumblingstatue](https://github.com/crumblingstatue)!, [SiebenCorgie](https://github.com/SiebenCorgie)) * [x] Fix "follow system theme" not working on initial startup (winit issue, pinning to 0.30.2 for now). * [x] Fix `request_repaint_after` --------- Co-authored-by: mwcampbell <[email protected]> Co-authored-by: j-axa <[email protected]> Co-authored-by: DataTriny <[email protected]> Co-authored-by: Emil Ernerfeldt <[email protected]>

Hi, has there been an update on this? I see that this has been marked as completed, but I've updated my projects to 0.29.1 and the behaviour I showed above is still happening. Even when trying the official I assume this isn't the intended behaviour, but I don't know if this is experienced by others, I'm on Windows 11 if that helps. Thanks for your time! |

Just tested this on MacOS and Windows and can confirm that this doesn't work as expected (instead of disappearing, the window hangs until the next window is opened) |

Since #1889 we can now open an
eframewindow, close it, and keep running the application.What we want to do is to then be able to open another window and run that for a while, etc.
Thanks to #1919 this now works on Windows, but this does not yet work on Mac, due to rust-windowing/winit#2431. Linux is unknown.
