⚠️ Improved menu based on `egui::Popup` (#5716)
Continuation of #5713

**Silently breaking changes:**
- Menus now close on click by default, this is configurable via
`PopupCloseBehavior`

**Additional additions:**
- `Button::right_text`
- `StyleModifier`

This is a rewrite of the egui menus, with the following goals:
- submenu buttons should work everywhere, in a popup, context menu,
area, in some random Ui
- remove the menu state from Ui
- should work just like the previous menu
- ~proper support for keyboard navigation~
  - It's better now but requires further work to be perfect
- support `PopupCloseBehavior`

* Closes #4607

Fix sizing bug in `TextEdit::singleline` (#5640)
This PR reverts a change introduced in PR
https://github.com/emilk/egui/pull/3660 that caused a regression with
`TextEdit::singleline`. The original PR attempted to fix an issue with
the cursor in `TextEdit` inside `ScrollArea`, but it did so by adding
unnecessary size allocation to `TextEdit`, which breaks the layout when
`TextEdit::singleline` is used outside of `ScrollArea`.


![Image](https://github.com/user-attachments/assets/78fdf20a-0763-4b5f-b83b-64522f15b35b)

The regression introduced by #3660 is more severe, as it completely
breaks the layout of applications using `TextEdit::singleline`, as shown
in the following issues:

*   Closes https://github.com/emilk/egui/issues/5500
*   Closes https://github.com/emilk/egui/issues/5597

Furthermore, I was unable to reproduce the original bug from PR #3660 in
the current version of egui using the following code:

```rust
impl eframe::App for MyEguiApp {
    fn update(&mut self, ctx: &egui::Context, _: &mut eframe::Frame) {
        ctx.set_debug_on_hover(true);
        egui::CentralPanel::default().show(ctx, |ui| {
            ScrollArea::vertical().max_height(100.0).show(ui, |ui| {
                ui.add(TextEdit::multiline(&mut self.text).hint_text("Enter text here..."))
            });
        });
    }
}
```

This code attempts to recreate the layout shown in the video from PR
#3660, using a `ScrollArea` with limited height and a `TextEdit` inside.
However, the cursor hiding issue was not reproducible.

![Video_2025-01-26_17-54-24](https://github.com/user-attachments/assets/ca4750ea-8af8-4ab5-8c10-bdf73a090362)

Therefore, I believe the code added in PR #3660 is no longer necessary
and only creates more problems.

Mark all keys as up if the app loses focus (#5743)
In Rerun, pressing `Cmd+S` brings up a save dialog using `rfd`, but we
get not key-up event for the `S` key (in winit).
This leads to `S` being mistakenly marked as down when we switch back to
the app.

This PR takes the safe route and marks all keys as up when an egui app
loses focus.

Clarify platform-specific details for `Viewport` positioning (#5715)
On Wayland (and android apparently) it is not possible for applications
to position their windows or request the window position (for some
reason). This is not specified in the documentation.

proof: [`winit::set_outer_position`], [`winit::outer_position`],
[`winit::inner_position`] all specify that Android / Wayland are not
supported.

[`winit::set_outer_position`]:
https://docs.rs/winit/latest/winit/window/struct.Window.html#method.set_outer_position
[`winit::outer_position`]:
https://docs.rs/winit/latest/winit/window/struct.Window.html#method.outer_position
[`winit::inner_position`]:
https://docs.rs/winit/latest/winit/window/struct.Window.html#method.inner_position

* Maybe closes #4469
* the lack of support makes me sad. I believe this makes some items in
#3556 impossible on Wayland. Oh well!

Add pointer events and focus handling for apps run in a Shadow DOM (#5627)
* [x] I have followed the instructions in the PR template

This PR handles pointer events and focus which did following changes:
- `element_from_point` and focus is now acquired from root node object
by using `get_root_node` from document or a shadow root.
- `TextAgent` is appended individually in each shadow root.

These changes handles pointer events and focus well in a web app that
are running in a shadow dom, or else the hover pointer actions and
keyboard input events are not triggered in a shadow dom.
Helpful for building embeddable/multi-view web-apps.

Fix image_loader for animated image types (#5688)
Hi, after upgrading to 0.31.0 all of my beautiful static webp images
started failing to load. I use the image_loader to load those via the
`image` crate.

I noticed that with 0.31.0 there are additions to how animated image
types are handled with frames and such. And with those changes the frame
index is attached to the uri at the end. This was problematic for the
image_loader, because it wasn't updated to handle that frame tag at the
end of the uri, so when looking up the bytes, it would fail to match the
uri in the bytes cache (the bytes were being saved without the frame
index, but attempting to be fetched _with_ the frame index).

This fixes the image_loader for me with webp & gif. They don't load the
animations, but I think that is because I don't have the custom
image_loader set up so I'm not worried about that for myself. I'm not
sure if that part is problematic in general, or if its just the way I
have my features set up.

You can recreate the issue on master by swapping out the dependency
features in the `images` example like this:
```
# egui_extras = { workspace = true, features = ["default", "all_loaders"] }
# env_logger = { version = "0.10", default-features = false, features = [
#   "auto-color",
#   "humantime",
# ] }
# image = { workspace = true, features = ["jpeg", "png"] }
egui_extras = { workspace = true, features = ["image", "svg"] }
env_logger = { version = "0.10", default-features = false, features = [
  "auto-color",
  "humantime",
] }
image = { workspace = true, features = ["jpeg", "png", "webp", "gif"] }
```

Add `Popup` and `Tooltip`, unifying the previous behaviours (#5713)
This introduces new `Tooltip` and `Popup` structs that unify and extend
the old popups and tooltips.

`Popup` handles the positioning and optionally stores state on whether
the popup is open (for click based popups like `ComboBox`, menus,
context menus).
`Tooltip` is based on `Popup` and handles state of whether the tooltip
should be shown (which turns out to be quite complex to handles all the
edge cases).

Both `Popup` and `Tooltip` can easily be constructed from a `Response`
and then customized via builder methods.

This also introduces `PositionAlign`, for aligning something outside of
a `Rect` (in contrast to `Align2` for aligning inside a `Rect`). But I
don't like the name, any suggestions? Inspired by [mui's tooltip
positioning](https://mui.com/material-ui/react-tooltip/#positioned-tooltips).

* Part of #4607 
* [x] I have followed the instructions in the PR template

TODOs:
- [x] Automatic tooltip positioning based on available space
- [x] Review / fix / remove all code TODOs 
- [x] ~Update the helper fns on `Response` to be consistent in naming
and parameters (Some use tooltip, some hover_ui, some take &self, some
take self)~ actually, I think the naming and parameter make sense on
second thought
- [x] Make sure all old code is marked deprecated

For discussion during review:
- the following check in `show_tooltip_for` still necessary?:
```rust
     let is_touch_screen = ctx.input(|i| i.any_touches());
     let allow_placing_below = !is_touch_screen; // There is a finger below. TODO: Needed?

Add `SnapshotResults` struct to egui_kittest (#5672)
I got annoyed by all the slightly different variations of "collect

added a struct to make this nice and simple.

One controversial thing: It panics when dropped. I wanted to ensure
people cannot forget to unwrap the results at the end, and this was the
best thing I could come up with. I don't think this is possible via
clippy lint or something like that.

⚠️ Rename `Rounding` to `CornerRadius` (#5673)

* Clarify
* Conform to other systems (e.g. Figma)
* Avoid confusion with `GuiRounding`

Emil Ernerfeldt 3c07e01d08
Improve tessellation quality (#5669)
## Defining what `Rounding` is
This PR defines what `Rounding` means: it is the corner radius of
underlying `RectShape` rectangle. If you use `StrokeKind::Inside`, this
means the rounding is of the outer part of the stroke. Conversely, if
you use `StrokeKind::Outside`, the stroke is outside the rounded
rectangle, so the stroke has an inner radius or `rounding`, and an outer
radius that is larger by `stroke.width`.

This definitions is the same as Figma uses.

## Improving general shape rendering
The rendering of filled shapes (rectangles, circles, paths, bezier) has
been rewritten. Instead of first painting the fill with the stroke on
top, we now paint them as one single mesh with shared vertices at the
border. This has several benefits:

* Less work (faster and with fewer vertices produced)
* No overdraw (nicer rendering of translucent shapes)
* Correct blending of stroke and fill

The logic for rendering thin strokes has also been improved, so that the
width of a stroke of `StrokeKind::Outside` never affects the filled area
(this used to be wrong for thin strokes).

## Improving of rectangle rendering
Rectangles also has specific improvements in how thin rectangles are
painted.
The handling of "Blur width" is also a lot better, and now works for
rectangles with strokes.
There also used to be bugs with specific combinations of corner radius
and stroke width, that are now fixed.

##  But why?
With the new `egui::Scene` we end up with a lot of zoomed out shapes,
with sub-pixel strokes. These need to look good! One thing led to
another, and then I became obsessive 😅

## Tessellation Test
In order to investigate the rendering, I created a Tessellation Test in
the `egui_demo_lib`.

This pull request fixes a subset of #5492 by saving the application
state when the `suspended` event is received on Android. This way, even
if the user exits the app and closes it manually right after changing
some state, it will be saved since `suspended` gets fired when the app
is exited. It does not fix the `on_exit` function not being fired - this
seems to be a winit bug (the `exiting` function in the winit application
handler trait is not called on exit). Once it gets fixed, it may be
possible to remove logic introduced by this PR (however, I am not sure
how it would handle the app being killed by the system when in the
background, that would have to be tested).

I've tested the logic by:
* Leaving from the app to the home screen, then killing it from the
"recent apps" menu
 * Leaving from the app to the "recent apps" menu and killing it
 * Restarting the device while the app was running

In all of these instances, the state was saved (the last one being a
pleasant surprise). It was tested on the repository mentioned in #5492
with my forked repository as the source for eframe (I unfortunately am
not able to test it in a larger project of mine due to dependence on
"3rd party" egui libraries (like egui_notify) which do not compile along
with the master branch of eframe (different versions of egui), but I
believe it should work in the same manner in all scenarios). Tests were
conducted on a Galaxy Tab S8 running Android 14, One UI 6.1.1.

CI passed on my fork.

* Closes https://github.com/emilk/egui/issues/5246

Tested on
* [x] Chromium
* [x] Firefox
* [x] Safari

On Chromium and Firefox we get one annoying frame with the wrong size,
which can mess up the layout of egui apps, but this PR is still a huge
improvement, and I don't want to spend more time on this right now.

Support RGB WebP images (#5586)
Current WebP loader assumes all WebP images to be RGBA, which is the
case if the image is animated (that's what `image` crate assumes at
least). Static images can instead choose to exclude its alpha channel,
though it seems to be more of a default choice to include it, even if
it's not being utilized. Currently, loading a static RGB WebP image will
cause a panic when `ColorImage::from_rgba_unmultiplied` gets called in
the loader

Change `Harness::run` to run until no more repaints are requested (#5580)
Previously, `Harness::run` just called `Harness::step` 3 times. If that
wasn't enough, tests would often call run multiple times so all
animations would finish properly.

Also, I introduced `HarnessBuilder::with_step_dt` to customize with how
big of a dt each frame is called. I set the default to 1.0 / 6.0 (~6fps)
so we don't waste cpu in tests waiting on animations.

`HarnessBuilder::max_steps` allows us to control how many steps
`Harness::run` should run before panicing.
The default is 6, so we run for up to 1.0 logical seconds (six frames at
6 fps), which should be enough to finish most animations.

Turns out a lot of snapshots where rendered before fully shown and had a
light opacity, those are now fixed.

Closes <https://github.com/emilk/egui/issues/3862>.

Factoring the `bool` members of `Response` into a bitfield, the size of
`Response` is now 96 bytes (down from 104).

I gave `Sense` the same treatment, however this has no effects on
`Response` due to padding. I've decided not to pursue `PointerState`, as
it is quite large (_many_ members that are sized and aligned to
multiples of 8 bytes), so I don't expect any noticeable benefit from
making handful of `bool`s slightly leaner.

In any case, the changes to `Sense` are already quite a bit more
intrusive than those to `Response`.
The previous implementation overloaded the names of the attributes
`click` and `drag` with similarly named methods that _construct_ `Sense`
with the corresponding flag set. Now, that the attributes can no longer
be accessed directly, I had to introduce methods with new names
(`senses_click()`, `senses_drag()` and `is_focusable()`). I don't think
this is the cleanest solution: the old methods are essentially redundant
now that the named constants like `Sense::CLICK` exist. I did however
not want to needlessly break backwards compatibility.
I am happy to revert it (or go further 🙂) if there are concerns.

- ./scripts/check.sh had other issues on my system (env: python: No such

Serialize window maximized state in `WindowSettings` (#5554)
A user of my Windows application reported a papercut where the
application restores its size on next load, but does not restore its
maximized state. This PR fixes that.

To test, I patched https://github.com/emilk/eframe_template to use my
local code since I knew that template saves/restores window data.
Testing methodology was to simply `cargo run`, maximize the application,
then close the application. `cargo run` again and the application should
start maximized.

Closes #1517.

⚠️ `Frame` now includes stroke width as part of padding (#5575)
* Part of https://github.com/emilk/egui/issues/4019

`Frame` now includes the width of the stroke as part of its size. From
the new docs:

### `Frame` docs
The total (outer) size of a frame is `content_size + inner_margin +
2*stroke.width + outer_margin`.

Everything within the stroke is filled with the fill color (if any).

```text
+-----------------^-------------------------------------- -+
|                 | outer_margin                           |
|    +------------v----^------------------------------+    |
|    |                 | stroke width                 |    |
|    |    +------------v---^---------------------+    |    |
|    |    |                | inner_margin        |    |    |
|    |    |    +-----------v----------------+    |    |    |
|    |    |    |             ^              |    |    |    |
|    |    |    |             |              |    |    |    |
|    |    |    |<------ content_size ------>|    |    |    |
|    |    |    |             |              |    |    |    |
|    |    |    |             v              |    |    |    |
|    |    |    +------- content_rect -------+    |    |    |
|    |    |                                      |    |    |
|    |    +-------------fill_rect ---------------+    |    |
|    |                                                |    |
|    +----------------- widget_rect ------------------+    |
|                                                          |
+---------------------- outer_rect ------------------------+
```

The four rectangles, from inside to outside, are:
* `content_rect`: the rectangle that is made available to the inner
[`Ui`] or widget.
* `fill_rect`: the rectangle that is filled with the fill color (inside
the stroke, if any).
* `widget_rect`: is the interactive part of the widget (what sense
clicks etc).
* `outer_rect`: what is allocated in the outer [`Ui`], and is what is
returned by [`Response::rect`].

### Notes
This required rewriting a lot of the layout code for `egui::Window`,
which was a massive pain. But now the window margin and stroke width is
properly accounted for everywhere.

Use `u8` in `Rounding`, and introduce `Roundingf` (#5563)
* Part of https://github.com/emilk/egui/issues/4019

As part of the work on adding a custom `Border` to everything, I want to
make sure that the size of `RectShape`, `Frame` and the future `Border`
is kept small (for performance reasons).

This PR changes the storage of the corner radius of rectangles from four
`f32` (one for each corner) into four `u8`. This mean the corner radius
can only be an integer in the range 0-255 (in ui points). This should be
enough for most people.

If you want to manipulate rounding using `f32`, there is a new
`Roundingf` to fill that niche.

Fix widgets sometimes being incorrectly marked as hovered (#5523)
An interactive widget should only be marked hovered if a click/drag
would start an interaction with it.

egui 0.30 introduced a feature where a thin interactive widget could be
hit even if it was partially behind a larger interactive widget.
Unfortunately, this introduced a bug where the top widget would still be
marked as hovered, even though a click would go through to the thin
widget below.

This bug was most notacible when trying to reisize a window by dragging
its corner, which often would result in dragging one of its sides
instead.

This PR fixes this bug.

Make all lines and rectangles crisp (#5518)
* Merge this first: https://github.com/emilk/egui/pull/5517

This aligns all rectangles and (horizontal or vertical) line segments to
the physical pixel grid in the `epaint::Tessellator`, making these
shapes appear crisp everywhere.

* Closes https://github.com/emilk/egui/issues/5164
* Closes https://github.com/emilk/egui/issues/3667

This undoes a lot of the explicit, egui-side aligning added in:
* https://github.com/emilk/egui/pull/4943

The new approach has several benefits over the old one:

* It is done automatically by epaint, so it is applied to everything (no
longer opt-in)
* It is applied after any layer transforms (so it always works)
* It makes line segments crisper on high-DPI screens
* All filled rectangles now has sides that end on pixel boundaries

Native is already delayed by a frame because it calls

after drawing. On web however, we process input including viewport
commands separately from drawing.

Improve hit-test of thin widgets, and widgets across layers (#5468)
When there are multiple layers (e.g. with custom transforms) close to
each other, the hit test code used to only consider widgets in the layer
directly under the mouse. This can make it difficult to hit thin widgets
just on the outside of a transform layer.

This PR fixes that.

It also prioritizes thin widgets, so that if there is both a thin widget
and a thick widget under the mouse cursor, you will always hit the thin
widgets, even if the thin widgets is layered behind the thick one. This
makes it easier to hit thin resize-handles.

In theory this should allow us to make `resize_grab_radius_side` and
`resize_grab_radius_corner` smaller in a future PR, if we want to.

Use `profiling` crate to support more profiler backends (#5150)
Hey! I am not sure if this is something that's been considered before
and decided against (I couldn't find any PR's or issues).

This change removes the internal profiling macros in library crates and
the `puffin` feature and replaces it with similar functions in the
[profiling](https://github.com/aclysma/profiling) crate. This crate
provides a layer of abstraction over various profiler instrumentation
crates and allows library users to pick their favorite (supported)
profiler.

An additional benefit for puffin users is that dependencies of egui are
included in the instrumentation output too (mainly wgpu which uses the
profiling crate), so more details might be available when profiling.

A breaking change is that instead of using the `puffin` feature on egui,
users that want to profile the crate with puffin instead have to enable
the `profile-with-puffin` feature on the profiling crate. Similarly they
could instead choose to use `profile-with-tracy` etc.

I tried to add a 'tracy' feature to egui_demo_app in order to showcase ,
however the /scripts/check.sh currently breaks on mutually exclusive
features (which this introduces), so I decided against including it for
the initial PR. I'm happy to iterate more on this if there is interest
in taking this PR though.

Screenshot showing the additional info for wgpu now available when using
puffin

Android support is "almost there". This PR pushes it just a bit further
by allowing `eframe` to be used on Android. It works by smuggling the
`AndroidApp` required by `winit` through `NativeOptions`.

The example isn't great because it doesn't leave space on the display
for Android's top status bar or the lower navigation bar. I don't know
what to do about that, yet. This is as far as I've managed to get it
working.

Another problem is that the development environment setup is completely
awful for Android unless you happen to already be a full-time Android
developer with everything configured on your build host. As a Rustacean,
this makes me very sad.

I've had some luck moving all of that mess to a container, adapted from
https://github.com/SergioRibera/docker-rust-android. It takes care of
all of the build dependencies, Android SDK, and the `cargo-apk` patches
for bugs that I hit while getting the example to work on my device. (I
also had to install an adb driver on my host and downloaded the Android
platform-tools to get access to `adb`. An alternative is exposing the
USB device to Docker. On Windows hosts, that means [installing
`usbipd`](https://learn.microsoft.com/en-us/windows/wsl/connect-usb). A
second alternative is using an `mtp` client to upload the APK as a file
with USB file transfer enabled, then manually install it through the
device's file manager.)

I'm not including the docker stuff in this PR, but here are the files
and instructions for future reference (and it will probably simplify
manual testing and CI, FWIW!)

Add screenshot support for eframe web (#5438)
This implements web support for taking screenshots in an eframe app (and
adds a nice demo).
It also updates the native screenshot implementation to work with the
wgpu gl backend.

The wgpu implementation is quite different than the native one because
we can't block to wait for the screenshot result, so instead I use a
channel to pass the result to a future frame asynchronously.

Fix drag-and-drop termination condition bug (#5452)
I introduced this in #5433.

TL;DR: there are two termination conditions for drag-and-drop
operations:
- ESC
- release mouse

The former _must_ happen at frame start (to properly capture the
keystroke). The latter _must_ happen at end-of-frame (to _not_ shadow
the mouse release event from user code).

This is now properly documented.

### Problem
When clicking on a TextEdit sometimes the cursor doesn't appear
immediately which makes it feel like the click was not registered for a
second. This is because the start time for the blinking animation is
only reset on keyboard input, but not on mouse interaction.

It's hard to tell on the video but the cursor doesn't show immediately
after clicking if the blink timer happens to be off.

### Solution
Reset the click timer every time a `TextEdit` is clicked. 

Additionally, the cursor is now correctly painted on the pixel boundary.
IMO we should default to 1px cursor (instead of 2px) but that's not
included in this PR. Happy to make that change too.

Move `egui::util::cache` to `egui::cache`; add `FramePublisher` (#5426)
This moves `egui::util::cache` to `egui::cache` (the old path is
deprecated, but still works).

It also adds the `FramePublisher` helper, which can be used to publish a
value which will be retained for this frame and the next:

``` rs
pub type MyPublisher = egui::cache::FramePublisher<MyKey, MyValue>;

// Publish:
ctx.memory_mut(|mem| {
    mem.caches.cache::<MyPublisher>().set(key, value);
});

// Retrieve:
let value: Option<MyValue> = ctx.memory_mut(|mem| {
    mem.caches
        .cache::<MyPublisher>()
        .get(key)
        .clone()

### Before
Notice how the cursor hides after third enter and when the line is long.


https://github.com/user-attachments/assets/8e45736e-d6c7-4dc6-94d0-213188c199ff

### After
Cursor is always visible


https://github.com/user-attachments/assets/43200683-3524-471b-990a-eb7b49385fa9


- `ScrollArea` now checks if there's a `scroll_target` in `begin`, if
there is, it saves it because it's not from its children, then restore
it in `end`.
- `TextEdit` now allocates additional space if its galley grows during
the frame. This is needed so that any surrounding `ScrollArea` can bring
the cursor to view, otherwise the cursor lays outside the the
`ScrollArea`'s `content_ui`.

Add `Modal` and `Memory::set_modal_layer` (#5358)
* Closes #686 
* Closes #839 
* #5370 should be merged before this
* [x] I have followed the instructions in the PR template

This adds modals to egui. 
This PR
- adds a new `Modal` struct
- adds `Memory::set_modal_layer` to limit focus to a layer and above
(used by the modal struct, but could also be used by custom modal
implementations)
- adds `Memory::allows_interaction` to check if a layer is behind a
modal layer, deprecating `Layer::allows_interaction`



Current problems:
- ~When a button is focused before the modal opens, it stays focused and
you also can't hit tab to focus the next widget. Seems like focus is
"stuck" on that widget until you hit escape. This might be related to
https://github.com/emilk/egui/issues/5359~ fixed!

Possible future improvements: 
- The titlebar from `window` should be made into a separate widget and
added to the modal
- The state whether the modal is open should be stored in egui
(optionally), similar to popup and menu. Ideally before this we would
refactor popup state to unify popup and menu

forward x11 and wayland features to glutin (#5391)
eframe has features for selecting between x11 and wayland. eframe does
not forward the features to glutin. This makes glutin always compile
with both backends enabled. This change forwards the feature. This
allows users of egui to compile less dependencies when they only need
one of x11, wayland.

To understand this change, read the glutin Cargo.toml [1] and the glutin
build.rs [2]. You always have to enable glutin's glx feature with the
x11 feature. The other default features (egl, wgl) stay enabled. This is
intentional so that everything continues to work as before. We could
further minimize when egl and wgl are enabled, but that is not part of
this change. There is little reason to do so because those feature
already only add dependencies when you compile glutin for the right
platform (for example wgl on windows).

egui_kittest: Allow passing state to the app closure (#5313)
The allows us to pass any state to the ui closure. While it is possible
to just store state in the closure itself, accessing that state after
the harness was created to e.g. read or modify it would require interior
mutability. With this change there are new `Harness::new_state`,
`Harness::run_state`, ... methods that allow passing state on each run.

This builds on top of #5301, which should be merged first

Put font data into Arc to reduce memory consumption (#5276)
egui never accesses the `FontDefinitions`' member fields mutably, except
in `fonts_tweak_ui` where it cloned the `FontDefinitions` object anyway.

This patch reduces system memory consumption for shared font
definitions.
And also removes some overhead from copying (e.g. for the per
`pixel_per_points` font atlas)

Also it allows to keep a copy of the font definitions outside of egui.

In my App that uses international fonts:
Before:

New:

The `RawInput::dropped_files` documentation referred to `NativeOptions`,
but the `drag_and_drop` option was moved to `ViewportBuilder` and is now
enabled by default.

Note that drag-and-drop is not *explicitly* enabled by default here, but
rather is enabled by default in winit. We only override winit's default
if the API consumer specifies it. It might be a good idea in general to
provide explicit defaults for everything in `ViewportBuilder` so we're
not relying on winit's behavior, but that's best left for another PR.

`jxl-oxide` makes use of the

Report egui::Window contents as children to accesskit (#5240)
Previously, all widgets would be listed in accesskit as children of the
toplevel window.
With this change, they will be reported as child of the `egui::Window`
they are in, Which should increase parseability of the ui for
screenreaders and integration tests.

Added an accesskit test to check that it is indeed working.

Fix textedit intrinsic size metric (#5275)
Since textedit is doing the justify layout calculation itself, we need
to report the original desired_size as intrinsic size, instead of the
value passed to allocate_space.

I wonder though, is it still necessary that the TextEdit does the
justify calculation itself instead of relying on the ui layout to do it?
As far as I understand it, justify should be handled by the
ui.allocate_space call.

Add egui testing library (#5166)
- closes #3491 
- closes #3926

This adds a testing library to egui based on
[kittest](https://github.com/rerun-io/kittest). Kittest is a new
[AccessKit](https://github.com/AccessKit/accesskit/)-based testing
library. The api is inspired by the js
[testing-library](https://testing-library.com/) where the idea is also
to query the dom based on accessibility attributes.
We made kittest with egui in mind but it should work with any rust gui
framework with AccessKit support.

It currently has support for:
- running the egui app, frame by frame
- building the AccessKit tree
- ergonomic queries via kittest
  - via e.g. get_by_name, get_by_role
- simulating events based on the accesskit node id
- creating arbitrary events based on Harness::input_mut
- rendering screenshots via wgpu
- snapshot tests with these screenshots

A simple test looks like this: 
```rust
fn main() {
    let mut checked = false;
    let app = |ctx: &Context| {
        CentralPanel::default().show(ctx, |ui| {
            ui.checkbox(&mut checked, "Check me!");
        });
    };

    let mut harness = Harness::builder().with_size(egui::Vec2::new(200.0, 100.0)).build(app);
    
    let checkbox = harness.get_by_name("Check me!");
    assert_eq!(checkbox.toggled(), Some(Toggled::False));
    checkbox.click();
    
    harness.run();

    let checkbox = harness.get_by_name("Check me!");
    assert_eq!(checkbox.toggled(), Some(Toggled::True));

    // You can even render the ui and do image snapshot tests
    #[cfg(all(feature = "wgpu", feature = "snapshot"))]
    egui_kittest::image_snapshot(&egui_kittest::wgpu::TestRenderer::new().render(&harness), "readme_example");
}
```

~Since getting wgpu to run in ci is a hassle, I'm taking another shot at
creating a software renderer for egui (ideally without a huge dependency
like skia)~ (this didn't work as well as I hoped and it turns out in CI
you can just run tests on a mac runner which comes with a real GPU)
 
Here is a example of a failed snapshot test in ci, it will say which
snapshot failed and upload an artifact with the before / after and diff
images:

Update ScrollArea drag velocity when drag stopped (#5175)
Fixes #5174.

The drag velocity was not being updated unless the cursor counted as
"dragging", which only happens when it's in motion. This effectively
guarantees that the drag velocity will never be zero, even if the cursor
is not moving, and results in spurious scroll velocity being applied
when the cursor is released.

Instead, we update the velocity only when the drag is stopped, which is
when the kinetic scrolling actually needs to begin. Note that we
immediately *apply* the scroll velocity on the same frame that we first
set it, to avoid a 1-frame gap where the scroll area doesn't move.

I believe that *not* setting `scroll_stuck_to_end` and `offset_target`
when the drag is released is the correct thing to do, as they should
apply immediately once the user stops dragging. Should we maybe clear
the drag velocity instead if `scroll_stuck_to_end` is true or
`offset_target` exists?

Prevent text shrinking in tooltips; round wrap-width to integer (#5161)
* Closes https://github.com/emilk/egui/pull/5106
* Closes https://github.com/emilk/egui/issues/5084


Protect against rounding errors in egui layout code.

Say the user asks to wrap at width 200.0.
The text layout wraps, and reports that the final width was 196.0
points.
This than trickles up the `Ui` chain and gets stored as the width for a
tooltip (say).
On the next frame, this is then set as the max width for the tooltip,
and we end up calling the text layout code again, this time with a wrap
width of 196.0.
Except, somewhere in the `Ui` chain with added margins etc, a rounding
error was introduced,
so that we actually set a wrap-width of 195.9997 instead.
Now the text that fit perfectly at 196.0 needs to wrap one word earlier,
and so the text re-wraps and reports a new width of 185.0 points.
And then the cycle continues.

So this PR limits the text wrap-width to be an integer.

Wgpu render pass on paint callback has now static lifetime (#5149)
A very common usability issue on egui-wgpu callbacks is that `paint`
can't access any data that doesn't strictly outlive the callback
resources' data. E.g. if the callback resources have an `Arc` to some
resource manager, you can't easily pull out resources since you
statically needed to ensure that those resource references outlived the
renderpass, whose lifetime was only constrained to the callback
resources themselves.

Wgpu 22 no longer has this restriction! Its (render/compute-)passes take
care of the lifetime of any passed resource internally. The lifetime
constraint is _still_ opt-out since it protects from a common runtime
error of adding commands/passes on the parent encoder while a previously
created pass wasn't closed yet.
This is not a concern in egui-wgpu since the paint method where we have
to access the render pass doesn't even have access to the encoder!

This fixes #5053 by adding a Sense parameter to UiBuilder, using that in
Context::create_widget, so the Widget is registered with the right Sense
/ focusable. Additionally, I've added a ignore_focus param to
create_widget, so the focus isn't surrendered / reregistered on
Ui::interact_bg.

The example from #5053 now works correctly:

<details><summary>Updated example code</summary>

```rust
            ui.button("I can focus");

                UiBuilder::new()
                    .sense(Sense::click())
                    .id_source("focus_test"),
                |ui| {
                    ui.label("I can focus for a single frame");
                    let response = ui.interact_bg();
                    let t = if response.has_focus() {
                        "has focus"
                    } else {
                        "doesn't have focus"
                    };
                    ui.label(t);

            );

            ui.button("I can't focus :(");
```

</p>

---

Also, I've added `Ui::interact_scope` to make it easier to read a Ui's
response in advance, without having to know about the internals of how
the Ui Ids get created.

This makes it really easy to created interactive container elements or
custom buttons, without having to use Galleys or
Painter::add(Shape::Noop) to style based on the interaction.

Center-align all text vertically (#5117)
* Closes https://github.com/emilk/egui/issues/4929
* Builds on top of https://github.com/emilk/egui/pull/2724 by @lictex
(ptal!)
* Implement `Center` and `Max` vertical text alignment properly
* Change default vertical alignment of text to centering

The end result is that text centers better in buttons and other places,
especially when mixing in emojis.
Before, mixing text of different heights (e.g. emojis and latin text) in
a label or button would cause the text to jump vertically.

This unifies the code paths in `update_texture` somewhat, so that the
texture sampler and bind group are always replaced.

Not sure whether removing and reinserting the texture from and into the
`textures` map, or creating a new bind group, has much of a performance
impact. An alternative, as described in #5121, would be to split the
functionality for updating a texture's data from updating its options,
so that we don't have to unconditionally update the bind group (or do
something like store the options to check if they're changed).

Fix `DragValue` range clamping (#5118)
When using a `DragValue`, there are three common modes of range clamping
that the user may want:

A) no clamping
B) clamping only user input (dragging or editing text), but leave
existing value intact
C) always clamp

The difference between mode B and C is:

```rs
let mut x = 42.0;
ui.add(DragValue::new(&mut x).range(0.0..=1.0));
// What will `x` be here?
```

With this PR, we now can get the three behaviors with:

* A): don't call `.range()` (or use `-Inf..=Inf`)
* B) call `.range()` and `.clamp_existing_to_range(false)`
* C) call `.range()`

## Slider clamping
Slider clamping is slightly different, since a slider always has a
range.

For a slider, there are these three cases to consider:

A) no clamping
B) clamp any value that the user enters, but leave existing values
intact
C) always clamp all values

Out of this, C should probably be the default.

I'm not sure what the best API is for this yet. Maybe an `enum` 🤔 


I'll take a pass on that in a future PR.

Add `Context::request_discard` (#5059)
* Closes https://github.com/emilk/egui/issues/4976
* Part of #4378 
* Implements parts of #843

### Background
Some widgets (like `Grid` and `Table`) needs to know the width of future
elements in order to properly size themselves. For instance, the width
of the first column of a grid may not be known until all rows of the
grid has been added, at which point it is too late. Therefore these
widgets store sizes from the previous frame. This leads to "first-frame
jitter", were the content is placed in the wrong place for one frame,
before being accurately laid out in subsequent frames.

### What
This PR adds the function `ctx.request_discard` which discards the
visual output and does another _pass_, i.e. calls the whole app UI code
once again (in eframe this means calling `App::update` again). This will
thus discard the shapes produced by the wrongly placed widgets, and
replace it with new shapes. Note that only the visual output is
discarded - all other output events are accumulated.

Calling `ctx.request_discard` should only be done in very rare
circumstances, e.g. when a `Grid` is first shown. Calling it every frame
will mean the UI code will become unnecessarily slow.

Two safe-guards are in place:

* `Options::max_passes` is by default 2, meaning egui will never do more
than 2 passes even if `request_discard` is called on every pass
* If multiple passes is done for multiple frames in a row, a warning
will be printed on the screen in debug builds:


![image](https://github.com/user-attachments/assets/c2c1e4a4-b7c9-4d7a-b3ad-abdd74bf449f)

### Breaking changes
A bunch of things that had "frame" in the name now has "pass" in them
instead:

* Functions called `begin_frame` and `end_frame` are now called
`begin_pass` and `end_pass`
* `FrameState` is now `PassState`
* etc


### TODO
* [x] Figure out good names for everything (`ctx.request_discard`)
* [x] Add API to query if we're gonna repeat this frame (to early-out
from expensive rendering)
* [x] Clear up naming confusion (pass vs frame) e.g. for `FrameState`
* [x] Figure out when to call this

Make Light & Dark Visuals Customizable When Following The System Theme (#4744)
* Closes <https://github.com/emilk/egui/issues/4490>
* [x] I have followed the instructions in the PR template

---

Unfortunately, this PR contains a bunch of breaking changes because
`Context` no longer has one style, but two. I could try to add some of
the methods back if that's desired.

The most subtle change is probably that `style_mut` mutates both the
dark and the light style (which from the usage in egui itself felt like
the right choice but might be surprising to users).

I decided to deviate a bit from the data structure suggested in the
linked issue.
Instead of this:
```rust
pub theme: Theme, // Dark or Light
pub follow_system_theme: bool, // Change [`Self::theme`] based on `RawInput::system_theme`?
```

I decided to add a `ThemePreference` enum and track the current system
theme separately.
This has a couple of benefits:
* The user's theme choice is not magically overwritten on the next
frame.
* A widget for changing the theme preference only needs to know the
`ThemePreference` and not two values.
* Persisting the `theme_preference` is fine (as opposed to persisting
the `theme` field which may actually be the system theme).

The `small_toggle_button` currently only toggles between dark and light
(so you can never get back to following the system). I think it's easy
to improve on this in a follow-up PR :)
I made the function `pub(crate)` for now because it should eventually be
a method on `ThemePreference`, not `Theme`.

To showcase the new capabilities I added a new example that uses
different "accent" colors in dark and light mode:

The syntax highlighting font size was always hardcoded to 12 or 10
depending on what case it was hitting (so not consistent). This is
particularly noticeable when you increase the font size to something
larger for the rest of the ui.

With this the default monospace font size is used by default.

Since the issue is closely related to #3549 I decided to implement the
ability to use override_font_id too.

## Visualized

Add `Ui::with_visual_transform` (#5055)
* [X] I have followed the instructions in the PR template

This allows you to transform widgets without having to put them on a new
layer.
Example usage: 


https://github.com/user-attachments/assets/6b547782-f15e-42ce-835f-e8febe8d2d65

```rust
use eframe::egui;
use eframe::egui::{Button, Frame, InnerResponse, Label, Pos2, RichText, UiBuilder, Widget};
use eframe::emath::TSTransform;
use eframe::NativeOptions;
use egui::{CentralPanel, Sense, WidgetInfo};

pub fn main() -> eframe::Result {
    eframe::run_simple_native("focus test", NativeOptions::default(), |ctx, _frame| {
        CentralPanel::default().show(ctx, |ui| {
            let response = ui.ctx().read_response(ui.next_auto_id());

            let pressed = response
                .as_ref()
                .is_some_and(|r| r.is_pointer_button_down_on());

            let hovered = response.as_ref().is_some_and(|r| r.hovered());

                (true, _) => 0.94,
                (_, true) => 1.06,
                _ => 1.0,
            };

            let scale = ui
                .ctx()
                .animate_value_with_time(ui.id().with("Down"), target_scale, 0.1);

            let mut center = response

                .map(|r| r.rect.center())
                .unwrap_or_else(|| Pos2::new(0.0, 0.0));
            if center.any_nan() {
                center = Pos2::new(0.0, 0.0);
            }

Export module `egui::frame` (#5087)
Remove the crate visibility of the frame module. Useful at least when
using `Frame::begin` as otherwise the returned type is opaque to library
users and prevents from creating containers that use `Frame` with a
similar interface.

Alternative is to only export `frame::Prepared` as `PreparedFrame` or
something, but I saw that other submodules of containers are already
public.

Liam Rosenfeld df9cd21248
Conditionally propagate web events using a filter in WebOptions (#5056)
Currently egui will prevent all web events from propagating. This causes
issues in contexts where you are using egui in a larger web context that
wants to receive events that egui does not directly respond to. For
example, currently using egui in a VSCode extension will block all app
hotkeys, such as saving and opening the panel.

This adds a closure to `WebOptions` that takes in a reference to the
egui event that is generated from a web event and returns if the
corresponding web event should be propagated or not. The default for it
is to always return false.

Alternatives I considered were:
1. Having the propagation filter be a property of the focus in memory.
That way it could be configured by the view currently selected. I opted
away from that because I wanted to avoid lowering eframe implementation
specific stuff into egui.
2. Having events contain a `web_propagate` flag that could be set when
handling them. However, that would not be compatible with the current
system of egui events being handled outside of the web event handler.

I just recently started using egui so I am not sure how idiomatic my
approach here is. I would be happy to switch this over to a different
architecture if there are suggestions.

Allow non-`static` `eframe::App` lifetime (#5060)
I love egui! Thank you Emil <3

This request specifically enables an `eframe::App` which stores a
lifetime.

In general, I believe this is necessary because `eframe::App` currently
does not seem to provide a good place to allocate and then borrow from
long-lived data between `update()` calls. To attempt to borrow such
long-lived data from a field of the `App` itself would be to create a
self-referential struct. A hacky alternative is to allocate long-lived
data with `Box::leak`, but that's a code smell and would cause problems
if a program ever creates multiple Apps.

As a more specific motivating example, I am developing with the
[inkwell](https://github.com/TheDan64/inkwell/) crate which requires
creating a `inkwell::context::Context` instance which is then borrowed
from by a bazillion things with a dedicated `'ctx` lifetime. I need such
a `inkwell::context::Context` for the duration of my `eframe::App` but I
can't store it as a field of the app. The most natural solution to me is
to simply to lift the inkwell context outside of the App and borrow from
it, but that currently fails because the AppCreator implicitly has a
`'static` lifetime requirement due to the use of `dyn` trait objects.

Here is a simpler, self-contained motivating example adapted from the
current [hello world example](https://docs.rs/eframe/latest/eframe/):

```rust
use eframe::egui;

struct LongLivedThing {
    message: String,
}

fn main() {
    let long_lived_thing = LongLivedThing {
        message: "Hello World!".to_string(),
    };

    let native_options = eframe::NativeOptions::default();
    eframe::run_native(
        "My egui App",
        native_options,
        Box::new(|cc| Ok(Box::new(MyEguiApp::new(cc, &long_lived_thing)))),
        //                                           ^^^^^^^^^^^^^^^^^
        //                                           BORROWING from long_lived_thing in App
    );
}

struct MyEguiApp<'a> {
    long_lived_thing: &'a LongLivedThing,
}

impl<'a> MyEguiApp<'a> {
    fn new(cc: &eframe::CreationContext<'_>, long_lived_thing: &'a LongLivedThing) -> Self {
        // Customize egui here with cc.egui_ctx.set_fonts and cc.egui_ctx.set_visuals.
        // Restore app state using cc.storage (requires the "persistence" feature).
        // Use the cc.gl (a glow::Context) to create graphics shaders and buffers that you can use
        // for e.g. egui::PaintCallback.
        MyEguiApp { long_lived_thing }
    }
}

impl<'a> eframe::App for MyEguiApp<'a> {
    fn update(&mut self, ctx: &egui::Context, frame: &mut eframe::Frame) {
        egui::CentralPanel::default().show(ctx, |ui| {
            ui.heading(&self.long_lived_thing.message);
        });
    }
}
```

This currently fails to compile with:
```plaintext
error[E0597]: `long_lived_thing` does not live long enough
  --> src/main.rs:16:55
   |
16 |         Box::new(|cc| Ok(Box::new(MyEguiApp::new(cc, &long_lived_thing)))),
   |         ----------------------------------------------^^^^^^^^^^^^^^^^----
   |         |        |                                    |
   |         |        |                                    borrowed value does not live long enough
   |         |        value captured here
   |         cast requires that `long_lived_thing` is borrowed for `'static`
17 |     );
18 | }
   | - `long_lived_thing` dropped here while still borrowed
   |
   = note: due to object lifetime defaults, `Box<dyn for<'a, 'b> FnOnce(&'a CreationContext<'b>) -> Result<Box<dyn App>, Box<dyn std::error::Error + Send + Sync>>>` actually means `Box<(dyn for<'a, 'b> FnOnce(&'a CreationContext<'b>) -> Result<Box<dyn App>, Box<dyn std::error::Error + Send + Sync>> + 'static)>`
```

With the added lifetimes in this request, I'm able to compile and run
this as expected on Ubuntu + Wayland. I see the CI has been emailing me
about some build failures and I'll do what I can to address those.
Currently running the check.sh script as well.

This is intended to resolve https://github.com/emilk/egui/issues/2152

I've been meaning to look into this for a while but finally bit the
bullet this week. Contrary to what I initially thought, the problem of
blurry lines is unrelated to feathering because it also happens with
feathering disabled.

The root cause is that lines tend to land on pixel boundaries, and
because of that, frequently used strokes (e.g. 1pt), end up partially
covering pixels. This is especially noticeable on 1ppp displays.

There were a couple of things to fix, namely: individual lines like
separators and indents but also shape strokes (e.g. Frame).

Lines were easy, I just made sure we round them to the nearest pixel
_center_, instead of the nearest pixel boundary.

Strokes were a little more complicated. To illustrate why, here’s an
example: if we're rendering a 5x5 rect (black fill, red stroke), we
would expect to see something like this:

![Screenshot 2024-08-11 at 15 01
41](https://github.com/user-attachments/assets/5a5d4434-0814-451b-8179-2864dc73c6a6)

The fill and the stroke to cover entire pixels. Instead, egui was
painting the stroke partially inside and partially outside, centered
around the shape’s path (blue line):

![Screenshot 2024-08-11 at 15 00
57](https://github.com/user-attachments/assets/4284dc91-5b6e-4422-994a-17d527a6f13b)

Both methods are valid for different use-cases but the first one is what
we’d typically want for UIs to feel crisp and pixel perfect. It's also
how CSS borders work (related to #4019 and #3284).

Luckily, we can use the normal computed for each `PathPoint` to adjust
the location of the stroke to be outside, inside, or in the middle.
These also are the 3 types of strokes available in tools like Photoshop.

This PR introduces an enum `StrokeKind` which determines if a
`PathStroke` should be tessellated outside, inside, or _on_ the path
itself. Where "outside" is defined by the directions normals point to.

Tessellator will now use `StrokeKind::Outside` for closed shapes like
rect, ellipse, etc. And `StrokeKind::Middle` for the rest since there's
no meaningful "outside" concept for open paths. This PR doesn't expose
`StrokeKind` to user-land, but we can implement that later so that users

especially to test hover effects. Everything should look crisper. Also
run it in a higher dpi screen to test that nothing broke 🙏.

Fix Issues: When focus is moved elsewhere, you must set
`state.ime_enabled = false`, otherwise the IME will have problems when
focus returns.

Fix Issues: A symptom of characters being copied when there are multiple
TextEdits.
Deletes all current `IME events`, preventing them from being copied to
`other TextEdits`, without saving the `TextEdit ID`,

( Related Issues: Some `LINUX` seem to trigger an IME enable event on
startup. So, when we gained focus, we do `state.ime_enabled = false`. )

Nicer looking text selection, especially in light mode (#5017)
* Closes https://github.com/emilk/egui/issues/4727

This changes the text selection painting from being painted on top of
the text, to being painted behind the text, but in front of any text
background. The result is much nicer looking text selection, especially
in light mode:

Douglas Dwyer 73bb4cedb4
Prevent `ScrollArea` contents from exceeding the container size (#5006)
When a `ScrollArea` is added to a `Ui` or its contents change
dynamically, the contents will briefly escape the container. This occurs
because `ScrollArea` internally maintains `content_is_too_large` flags,
from which it determines when to clip. The `content_is_too_large` flags
are calculated after painting, so they always lag one frame behind. This
can lead to flickering.

To fix this, I have changed the `ScrollArea` so that it always clips
scrollable content. I believe that this should fix things without
negatively impacting other behavior. To see this, consider how
`ScrollArea` calculates the `content_is_too_large` flag:

```rust
// This calculates a new inner rect, after painting, from the initial clip rect
let inner_rect = {
  // At this point this is the available size for the inner rect.
  let mut inner_size = inner_rect.size();
  
  for d in 0..2 {
      inner_size[d] = match (scroll_enabled[d], auto_shrink[d]) {
          (true, true) => inner_size[d].min(content_size[d]), // shrink scroll area if content is small
          (true, false) => inner_size[d], // let scroll area be larger than content; fill with blank space
          (false, true) => content_size[d], // Follow the content (expand/contract to fit it).
          (false, false) => inner_size[d].max(content_size[d]), // Expand to fit content
      };
  }
  
  Rect::from_min_size(inner_rect.min, inner_size)
};

let outer_rect = Rect::from_min_size(inner_rect.min, inner_rect.size() + current_bar_use);

let content_is_too_large = Vec2b::new(
  scroll_enabled[0] && inner_rect.width() < content_size.x,
  scroll_enabled[1] && inner_rect.height() < content_size.y,
);
```
If `scroll_enabled[d] == true`, then the actual `inner_rect` (which is
calculated after painting contents) will always be smaller than the
original `inner_rect`. Hence, it is safe to unconditionally clip the
contents to `inner_rect` whenever `scroll_enabled[d] == true`.

Avoid some `Id` clashes by seeding auto-ids with child id (#4840)
I was having trouble with id collisions and was not able to resolve it
using `push_id` and `child_ui_with_id_source`.

When investigating the issue I found
https://github.com/emilk/egui/pull/2262 which matched the issues I had
so I forked egui and implemented the changes from that PR for the latest
version.

It solved the issue for me.

I did not notice any regressions in my project or the egui web viewer.

Fix virtual keyboard on (mobile) web (#4855)
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 :)

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
