Selected text now gets the color of `visuals.selection.stroke.color`.
This means you can have inverted colors for selected text, like in the
new test:
<img width="154" height="46" alt="image"
src="https://github.com/user-attachments/assets/2666361d-d7e2-4d50-8e4d-2fcc128f1a81"
/>
It also means the color of selected text in labels matches that of the
text color of selected buttons.
Changed it to use labeled_by to avoid kittest finding the label when
searching for the ComboBox and also set the value so a screen reader
will know what's selected.
### Problem
Letting go of the modifier key before the last momentum-scroll events
arrive will cause the scroll direction to change. This problem can be
seen by going to egui.rs and opening the "Scene" example. Hold down
shift, start a momentum-scroll (on a Mac trackpad), then quickly let go
of shift: you'll see the scroll direction change, which feels wrong.
### Solution
Store the modifiers at the start of the event, thanks to the new `phase`
info added in
* https://github.com/emilk/egui/pull/7669
Note that this solution only works on native; not on web.
### Other
* Break out wheel/scroll handling into own file
* Simplify it a lot by deciding late on wether an input is a scroll or a
zoom
* Assume input is already smooth if there are `phase` events

Moves `ends_with_newline` into `PlacedRow` to avoid clones during
layout.
I don't think there was a rationale stronger than "don't change too
much" for not doing this in https://github.com/emilk/egui/pull/5411, so
I should've just done this from the start.
This was a significant part of the profile for text layout (as it cloned
almost every `Row`, even though it only needed to change a single
boolean).
Before:

(note that these profiles focus solely on the top-level
`Galley::layout_inline` subtree, also don't compare sample count as the
duration of these tests was completely arbitrary)

(As usual, the tests fail for me even on master but the failures on
master and with these changes seem the same :))
This PR adds `Plugin::on_widget_under_pointer` which gets called
whenever a widget is created whose rect contains the pointer.
The point of the hook is to capture a stack trace which can be used to
map widgets to their corresponding source code so it must be called
while the widget is being created. The obvious concern is performance
impact. However, since it's only called for rects under the cursor, the
effect seems negligible afaict. It's under `debug_assertions` just in
case.
This change is needed so we can publish the widget inspector we've been
working on. Basically a plugin that allows us to jump from any widget
back to their corresponding source code.
This video shows the plugin configured to open the corresponding code in
github, but normally it would open your local editor.
Update: [Live demo](https://membrane-io.github.io/egui/) (Firefox/Safari
not yet supported. `Cmd-I` to inspect. `Tab` to cycle filters. `Click`
to open). It will try to open a file under
`/home/runner/work/egui/egui/` so it won't work, but you get the idea.

## What's next
After this gets merged I plan to publish the above plugin as its own
crate, that way we can iterate and release quickly while things are
still changing. I agree it would make sense to eventually merge it into
the main egui repo (like @emilk suggested in #4650).

Previously, when `rect` was taller than it was wide, the spinner would
render far outside the given rectangle. Now, it always renders inside
the smaller of the two dimensions.
I noticed this when upgrading from 0.30 to 0.32. I have an image that's
significantly taller than it is wide. In 0.32, when the image is
loading, it shows the spinner. Since the spinner radius is determined
solely based on rectangle height, the spinner ends up far too wide and
covers other elements.

This changes egui to create an AccessKit node for each `Ui`. I'm not
sure if this alone will directly improve accessibility, but it should
make it easier to create the correct parent / child relations (e.g.
grouping menus as children of menu buttons).
Instead of having a global stack of parent ids, they are now passed via
a parent_id field in `UiBuilder`.
If having all these `GenericContainer` nodes somehow is bad for
accessibility, the PR could also be changed to only create nodes if
there is actually some accessibility info with it (the relevant is
currently commented-out in the PR). But I think screen readers should
just ignore these nodes, so it should be fine? We could also use this as
motivation to git red of some unnecessary wrapped `Ui`s, e.g.
CentralPanel creates 3 Uis when 2 should be enough (the initial Ui and a
Frame, maybe we could even only show the `Frame` if we can give it an
UiBuilder and somehow show the Frame with `Ui::new`).
Here is a screenshot from the accessibility inspector
(https://github.com/emilk/egui/pull/7368) with this PR:
<img width="431" height="744" alt="Screenshot 2025-07-24 at 12 09 55"

Without this PR:
https://github.com/user-attachments/assets/270e32fc-9c7a-4dad-8c90-7638c487a602
Adds an accessibility inspector plugin that shows the current AccessKit
tree:
https://github.com/user-attachments/assets/78f4f221-1bd2-4ce4-adf5-fc3b00f5c16c
Macos has a built in accessibility inspector, but it doesn't seem to
work with AccessKit / eframe so this provides some insight into the
accesskit state.
This also showed a couple issues that are easy to fix:
- [ ] Links show up as `Label` instead of links
- [ ] Not all supported actions are advertised (e.g. scrolling)
- [ ] The resize handles in windows shouldn't be focusable
- [ ] Checkbox has no value
- [ ] Menus should have the button as parent widget (not 100% sure on
this one)
Currently the plugin lives in the demo app, but I think it should be
moved somewhere else. Maybe egui_extras?
This could also be relevant for #4650
This PR is a continuation of #4915 by @frederik-uni and @lucasmerlin
that introduces support for keeping egui content within the 'safe area'
on iOS (avoiding the notch / dynamic island / menu bar etc.), with the
following changes:
- `SafeArea` now wraps `MarginF32` and has been renamed to
`SafeAreaInsets` to clarify its purpose.
- `InputState::screen_rect` is now marked as deprecated in favour of
either `viewport_rect` (which contains the entire screen), or
`content_rect` (which is the viewport rect with the safe area insets
removed).
- I added some comments to the safe area insets logic pointing out the
[safe area API coming in winit
v0.31](https://github.com/rust-windowing/winit/issues/3910).

* Closes https://github.com/rerun-io/rerun/issues/11301
This fixes a bug where a menu could get stuck, not closing at all, when
the currently open submenu stops being shown.
I also added a way to reproduce this to the demo, as well as a test
ensuring that there is no race condition in the fix.
This was initially a PR to add kitdiff, but this now lives in it's own
crate: https://github.com/rerun-io/kitdiff
I needed to make the image loaders public, this way it's possible to
compose image loaders together (which allowed me to create a image diff
loader that uses two other image loaders). But you can't use the
`ctx.try_load_image` since that would deadlock, so you have to store a
reference to the other loader in the wrapping loader.
This adds a new `Plugin` trait and new `input_hook` and `output_hook`
plugin fns. Having a `Plugin` trait should make it easier to store state
in the plugin and improve discoverability of possible plugin hooks.
The old `on_begin_pass` and `on_end_pass` have been ported to use the
new plugin trait, should we deprecate them?
* follow up to #7514
That PR changed the tooltip to preserve the wrapping, which made the
tooltip kind of useless. With this PR the wrapping is reset for the
tooltip.

Currently `ui.put` moves the cursor after the placed widget. In my
opinion that is a bit unexpected and counterproductive in most cases
where `ui.put` makes sense.
The following example breakes with the current behavior and looks right
with my change:
```rs
ui.horizontal(|ui| {
let custom_button_id = Id::new("custom_button");
let response = Button::new((
Atom::custom(custom_button_id, Vec2::splat(18.0)),
"Look at my mini button!",
))
.atom_ui(ui);
if let Some(rect) = response.rect(custom_button_id) {
ui.put(rect, Button::new("🔎").frame_when_inactive(false));
}
let custom_button_id = Id::new("custom_button");
let response = Button::new((
Atom::custom(custom_button_id, Vec2::splat(18.0)),
"Look at my mini button!",
))
.atom_ui(ui);
if let Some(rect) = response.rect(custom_button_id) {
ui.put(rect, Button::new("🔎").frame_when_inactive(false));
}
});
ui.add_space(10.0);
let response = ui.button("Notifications");
ui.put(
Rect::from_center_size(response.rect.right_top(), Vec2::splat(12.0)),
|ui: &mut Ui| {
Frame::new()
.fill(Color32::RED)
.corner_radius(10.0)
.show(ui, |ui| {
ui.label(RichText::new("11").size(8.0).color(Color32::WHITE));
}).response
},
);
ui.button("Some other button");
```

I had a look at reruns source code and there are no uses of `ui.put`
that would break with this change (very little usages in general).
## Alternatives
Instead of a breaking change we could of course instead introduce a new
metheod (e.g. `Ui::place`?).

Adds a check for `ui.is_enabled()` when displaying the SubMenu items.
There were a few places the condition could be placed, but I figured
there was simplest. The inner button will already not be able to be
clicked due to ui being disabled.

On touch devices you don't want the keyboard to disappear when
scrolling, so this PR adds a `SurrenderFocusOn` enum to configure on
what interaction to surrender focus.
If the ScrollArea's contents are smaller than the inner rect, but the
scrollbar is set to always visible, clicking on it led to a remap from
an empty range to calculate the new offset, which triggered a debug
assertion in the remap function, because the result is indeterminate.
Since in this case there is no need to scroll, we just skip the remap
and set the offset to 0 directly.
