I removed (I hope so) all wildcard imports I found.
For me on my pc this improved the build time:
- for egui -5s
- for eframe -12s
* [x] I have followed the instructions in the PR template
Hello,
I have made several corrections to stabilize the virtual keyboard on
Android and IOS (Chrome and Safari).
I don't know if these corrections can have a negative impact in certain
situations, but at the moment they don't cause me any problems.
I'll be happy to answer any questions you may have about these fixes.
These fixes correct several issues with the display of the virtual
keyboard, particularly since update 0.28, which can be reproduced on the
egui demo site.
We hope to be able to help you.
Thanks a lot for your work, I'm having a lot of fun with egui :)
On multiple-monitor systems, eframe was incorrectly selecting first ones
dimensions for centering
Would also appretiate releasing 0.28.2 with fix included on crates.io

This PR
- adds a pipeline to check the ios build
- removes the iOS WaitUntil workaround, which doesn't seem to be
necessary anymore after the winit update (and caused the build for iOS
to fail again because of a missing self
- ~removes a iOS workaround for window size which doesn't seem necessary
anymore~
Turns out it was still needed (but you need to actually restart the app
for the issue to show up, so I didn't catch it first)
- fixes some cargo check errors in run.rs
I've done all these changes in a single PR because otherwise the
pipeline doesn't run but I can also split them in separate PRs if that
makes it easier to review
* Fixes#3959
There are two bugs racing each other here, which is why it sometimes
crashes and sometimes the app just silently exists
Bug 1
When the window is recreated a Destroyed event arrives (due to the Drop
of the old window). The code that receives this event does not look to
see if its the main viewport or a secondary one and unconditionally
closes the app. The code path for other platforms is slightly different
and does check.
I have moved the code that handles the destroy to be in the same place
and have the same behavior as the other platforms.
Bug 2
At recreate time the window and winit entries of the viewport are set to
None (forcin g them to be recreated). But the surface is still bound to
the old window, this causes the next context switch to fail. So I simply
added a viewport.gl_surface = None too,
This is my first egui PR so I hope I have not broken anything. If
nothing else I understand a little better how egui works.
This updates winit to 0.30.5.
https://github.com/emilk/egui/pull/4849 Had to pin the version to
0.30.2, as a Winit patch changed the behavior of selecting a theme.
Winit 0.30.5 reverts this, so we could stick with `window.theme()`, but
the newly added `ActiveEventLoop::system_theme` is more like what egui
wants anyway, as individual windows can have theme overrides.
Also bump `smithay-clipboard` to prevent some now duplicate
dependencies.
* Some initial progress towards #4490
This PR just moves `Theme` and the "follow system theme" settings to
egui and adds `RawInput.system_theme`.
A follow-up PR can then introduce the two separate `dark_mode_style` and
`light_mode_style` fields on `Options`.

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:
https://github.com/emilk/egui/pull/4466
Seems to have gone stale & is missing some bits.
https://github.com/emilk/egui/pull/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](https://github.com/rust-windowing/winit/issues/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!

Clarified that `eframe::run_simple_native()` does in fact save some
state (if persistence is enabled) but does not allow user to save state.
Improved `change_gl_context()`
**Before:**
Create a new `not_current_glcontext`.
**After:**
If `not_current_glcontext` exists, apply it. Otherwise, create it.
This will make the program smoother when dragging, etc.
* Fixes https://github.com/rerun-io/rerun/issues/6638
* Related? https://github.com/emilk/egui/issues/4563
This improves how an eframe canvas works inside of a larger web page,
and how it works when there are multiple eframe apps in the same page.
`eframe` will set `tabindex="0"` on the canvas automatically, making it
focusable.
It will also set `outline: none` on the CSS, so the focused canvas won't
have an ugly outline.
## Breaking changes
You may wanna add this to your `index.html` to give the canvas focus on
startup:
```js
document.getElementById("the_canvas_id").focus();
```
## Test setup
```sh
./scripts/build_demo_web.sh
./scripts/start_server.sh
open http://localhost:8888/multiple_apps.html
```
Then open the "Input Event History" and "Text Edit" windows
## Tested
* Chromium
* [x] drag-and-drop of files
* Test both when a `TextEdit` is focused and when it is not:
* [x] `Event::Key`
* [x] `Event::Text`
* [x] copy-cut-paste
* [x] Wheel scroll
* [x] `Event::PointerGone`
* [x] Mouse drag
* [x] Mouse click
* [x] Mouse right-click
* [x] Defocus all eframe canvas, and then start typing text
* [x] Firefox (all of the above)
* [x] Desktop Safari (all of the above)
* [x] Mobile Safari

`directories-next` was created because `directories` was not maintained
at the time. However, `directories` has gotten active maintainership
since, and it has received more updates than `directories-next`.
`directories` also has more recent downloads than its `next`
counterpart, so it might make sense to switch to it, to avoid
unnecessary duplicate dependencies, where a project depends transitively
on both `directories` and `directories-next`.
The main question is whether we depend on any specific behavior from
`directories-next`.
- Closes https://github.com/emilk/egui/issues/4060 - no longer aligned
to top
- Closes https://github.com/emilk/egui/issues/4479 - `canvas.style` is
not set anywhere anymore
- Closes https://github.com/emilk/egui/issues/2231 - same as #4060
- Closes https://github.com/emilk/egui/issues/3618 - there is now one
`<input>` per `eframe` app, and it's removed transitively by
`WebRunner::destroy -> AppRunner::drop -> TextAgent::drop`
This PR improves the text agent to make fewer assumptions about how
`egui` is embedded into the page:
- Text agent no longer sets the canvas position
- There is now a text agent for each instance of `WebRunner`
- The input element is now moved to the correct position, so the OS can
display the IME window in the correct place. Before it would typically
be outside of the viewport
The best way to test this is to build & server the web demo locally:
```
scripts/build_demo_web.sh && scripts/start_server.sh
```
Then open the EasyMark editor, and try using IME to input some emojis:
http://localhost:8888/#EasyMarkEditor
To open the emoji keyboard use:
- <kbd>win + .</kbd> on Windows
- <kbd>ctrl + cmd + space</kbd> on Mac
Tested on:
- [x] Windows
- [x] Linux
- [x] MacOS
- [x] Android
- [x] iOS
## Migration guide
The canvas no longer controls its own size/position on the page. This
means that those properties can now be controlled entirely via HTML and
CSS, and multiple separate `eframe` apps can coexist better on a single
page.
To match the old behavior, set the `canvas` width and height to 100% of
the `body` element:
```html
<html>
<body>
<canvas></canvas>
</body>
</html>
```
```css
/* remove default margins and use full viewport */
html, body {
margin: 0;
width: 100%;
height: 100%;
}
canvas {
/* match parent element size */
width: 100%;
height: 100%;
}
```
Note that there is no need to set `position: absolute`/`left: 50%;
transform: translateX(-50%)`/etc., and setting those properties may
poorly affect the sharpness of `egui`-rendered text.
Because `eframe` no longer updates the canvas style in any way, it also
means that on mobile, the canvas no longer collapses upwards to make
space for a mobile keyboard. This should be solved in other ways:
https://github.com/emilk/egui/issues/4572
The closure passed to `eframe::run_native` now returns a `Result`,
allowing you to return an error during app creation, which will be
returned to the caller of `run_native`.
This means you need to wrap your `Box::new(MyApp::new(…))` in an
`Ok(…)`.
* Closes https://github.com/emilk/egui/issues/4474
The closure is now stored in `WebRunner` and dropped in the next
`request_animation_frame` instead of being "leaked" via `forget`

Currently, if the size of the canvas element changes independently of
the size of the browser window (e.g. due to its parent element
shrinking), then no repaints are scheduled.
This PR replaces the `resize` event with a `ResizeObserver`, which
ensures that _any_ resize of the canvas element (including those caused
by browser window resizes) trigger a repaint. The repaint is done
synchronously as part of the resize event, to reduce any potential
flickering.
The result seems to pass the rendering tests on most platform+browser
combinations. We tested:
- Chrome, Firefox, Safari on macOS
- Chrome, Firefox on Linux (ubuntu and arch, both running wayland)
- Chrome, Firefox on Windows
Firefox still has some antialiasing issues on Linux platforms, but this
antialiasing also happens on `master`, so this PR is not a regression
there.
The code setting `canvas.style.width` and `canvas.style.height` at the
start of `AppRunner::logic` was also removed - the canvas _display_ size
is now fully controlled by CSS, e.g. by setting `canvas { width: 100%;
height: 100%; }`.
The approach used here is described in
https://webglfundamentals.org/webgl/lessons/webgl-resizing-the-canvas.html
Note: The only remaining place where egui updates the style of the
canvas it is rendering to is some of the IME/mobile input handling code.
Fixing that is out of scope for this PR, and will be done in a followup
PR.
This allows customizing the persistence path in NativeOptions.
Previously, persistence wouldn't work with android because
directories-next doesn't support android so eframe would just fail to
find a place where it could store its config.
* Closes#4098 (android users can now specify a path that works with
android, by e.g. using app_dirs2, which supports android)

Not sure what the "best practice" is, to me it seems like one should
import from "the original location" if possible, but now it should at
least be possible to not re-export ahash without any breakage in the
egui code base (but possibly in projects using egui, so one should
probably deprecate it if one would like to go that path). It also seems
like epaint re-exports ahash.
For integrations: just emit `egui::Event::MouseWheel` (like before).
egui will interpret that as zoom or pan.

### Investigation notes
- [`WindowSettings.inner_position_pixels` and
`WindowSettings.outer_position_pixels`](https://github.com/emilk/egui/blob/master/crates/egui-winit/src/window_settings.rs#L8-L12)
are stored in physical/pixel coordinates.
- `ViewportBuilder::with_position` expects to be passed a position in
_logical_ coordinates.
- Prior to this PR, the position was being passed from `WindowSettings`
to `with_position` [without any
scaling](https://github.com/emilk/egui/blob/master/crates/egui-winit/src/window_settings.rs#L61-L68).
This was the root cause of the issue.
- The fix is to first convert the position to logical coordinates,
respecting the scaling factor of the active monitor. This requires us to
first determine the active monitor, so I factored out some of the logic
in
[`clamp_pos_to_monitor`](https://github.com/emilk/egui/blob/master/crates/egui-winit/src/window_settings.rs#L130)
to find the active monitor.

Motivation: I want to replace `cargo-cranky` with workspace lints, first
available in Rust 1.74.
However, `cargo doc` would hange on `wgpu` and `wgpu-core` on 1.74 and
1.75… so now we're on 1.76.
I think this is fine - when 1.78 is released next week we're still two
versions behind the bleeding edge.
…and the branch name is just wrong 🤦
These are a replacement to the `objc` and `cocoa` crates.
This PR prevents:
- An extra copy when creating `NSData`
- A memory leak when creating `NSImage`
- A memory leak when creating `NSString`
And is generally a readability improvement.
Note that we define `NSApp` manually for now, the implementation in
`objc2-app-kit` is currently suboptimal and wouldn't allow you to check
whether the NSApplication has been created or not.
Related: https://github.com/emilk/egui/issues/4219, this should nicely
coincide with the Winit `0.30` release.

### Motivation
We want to offer our users a context menu with `Cut`, `Copy` and `Paste`
actions. `Paste` is not possible out of the box.
### Changes
This PR adds `ViewportCommand::RequestCut`,
`ViewportCommand::RequestCopy` and `ViewportCommand::RequestPaste`. They
are routed and handled after the example of
`ViewportCommand::Screenshot` and result in the same code being executed
as when the user uses `CTRL+V` style keyboard commands.
### Reasoning
In our last release we used an instance of
`egui_winit:📋:Clipboard` in order to get the `Paste`
functionality.
However Linux users on Wayland complained about broken clipboard
interaction (https://github.com/mikedilger/gossip/issues/617). After a
while of digging I could not find the issue although I have found
references to problems with multiple clipboards per handle before
(https://gitlab.gnome.org/GNOME/mutter/-/issues/1250) but I compared
mutter with weston and the problem occured on both.
So to solve this I set out to extend egui to access the clipboard
instance already present in egui_winit. Since there was no trivial way
to reach the instance of `egui_winit::State` I felt the best approach
was to follow the logic of the new `ViewportCommand::Screenshot`.
### Variations
It could make sense to make the introduced `enum ActionRequested` a part
of crates/egui/src/viewport.rs and to then wrap them into one single
`ViewportCommand::ActionRequest(ActionRequested)`.
### Example
```Rust
let mut text = String::new();
let response = ui.text_edit_singleline(&mut text);
if ui.button("Paste").clicked() {
response.request_focus();
ui.ctx().send_viewport_cmd(ViewportCommand::RequestPaste);
}
```

I would love some more testers of this.
I'm not sure if we really need the round-to-even code, but I'm hesitant
to out-right revert https://github.com/emilk/egui/pull/151 when I cannot
reproduce its problem. Keeping it seems quite safe though.

# Testing
Checkout the branch and run:
* `./scripts/start_server.sh`
* `./scripts/build_demo_web.sh` and then open
`http://localhost:8888/index.html#Rendering`
* `./scripts/build_demo_web.sh --wgpu` and then open
`http://localhost:8888/index.html#Rendering`
Check the "Rendering test" that the squares in the pixel alignment test
are perfectly sharp, like this:

fixed
* Firefox: ✅ Can reproduce problem on `master`, and it's now fixed
* Safari: ❌ Can't get it to work; giving up for now
Before, when setting the `zoom_factor`, the website was already
enlarged, but the zoom was ignored when calculating the logical window
size and mouse position, causing an offset between the actual cursor and
selected elements. That is addressed here

Previously, any frames in flight (`requestAnimationFrame`) on web were
not being cancelled (`cancelAnimationFrame`) when `WebRunner::destroy`
was called. If a user called `destroy`, then immediately removed the
canvas from the DOM, eframe could panic with a "failed to find (canvas)
element by id" error message.
This PR changes two things:
- The canvas element is directly referenced everywhere it's needed
instead of being looked up by `canvas_id`[^1]
- The RAF handle is stored in `WebRunner` and `cancelAnimationFrame` is
called on it inside of `WebRunner::destroy`[^2]
[^1]: The WebGL/WGPU backends were already holding onto the canvas (and
associated GPU context), so the change is just converting all the
`get_element_by_id` lookups to retrieve the canvas from the web runner
handle.
[^2]: There is only ever one frame in flight, so we store it directly as
a scalar field.

Update modifier state from web mouse events. This allows modifiers to be
correctly updated when the window is not in focus but the mouse is still
moving over the window.
# What's New
* eframe: Added `App::raw_input_hook` allows for the manipulation or
filtering of raw input events
A filter applied to raw input before [`Self::update`]
This allows for the manipulation or filtering of input events before
they are processed by egui.
This can be used to exclude specific keyboard shortcuts, mouse events,
etc.
Additionally, it can be used to add custom keyboard or mouse events
generated by a virtual keyboard.
* examples: Added an example to demonstrates how to implement a custom
virtual keyboard.
[eframe-custom-keypad.webm](https://github.com/emilk/egui/assets/1274171/a9dc8e34-2c35-4172-b7ef-41010b794fb8)
Raw mouse movement is unaccelerated and unclamped by screen boundaries,
and does not relate to any position on the screen.
It is useful in certain situations such as draggable values and 3D
cameras, where screen position does not matter.
https://github.com/emilk/egui/assets/1700581/1400e6a6-0573-41b9-99a1-a9cd305aa1a3
Added `Event::MouseMoved` for integrations to supply raw mouse movement.
Added `Response:drag_motion` to get the raw mouse movement, but will
fall back to delta in case the integration does not supply it.
Nothing should be breaking, but third-party integrations that can send
`Event::MouseMoved` should be updated to do so.
Based on #1614 but updated to the current version, and with better
fallback behaviour.
* Closes#1611
* Supersedes #1614
After merging PR #4036, build errors occurred in eframe-related

Workspace dependencies can be annoying.
If you don't set them to `default-features=false`, then you cannot opt
out of their default features anywhere else, and get warnings if you
try.
So you set `default-features=false`, and then you need to manually opt
in to the default features everywhere else.
Or, as in my case, don't.
I don't have the energy to do this tonight, so I'll just revert.
