egui will interpret that as zoom or pan.

I took the liberty of removing that comment since I *think* that I got
all "relevant" ones (showing up more than once, sort of).
`parking_lot`'s `RwLock` allows this, so probably `epaint`'s `RwLock`
should too.
Although I'm not sure how much it's intended for users, rather than just
internal use by `egui`.

### 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.
## Summary
This PR modifies `ScrollArea` and `Plot` to disable their interactions
when the UI is disabled.
## Changes
- Interaction with `ScrollArea` in `egui` is disabled when the UI is
disabled.
- Interaction with `Plot` in `egui_plot` is disabled when the UI is
disabled.
- These changes ensure that `ScrollArea` and `Plot` behave consistently
with the rest of the UI, preventing them from responding to user input
when the UI is in a disabled state.
## Impact
This PR enhances the consistency of `egui`'s UI behavior by ensuring
that all elements, including `ScrollArea` and `Plot`, respect the UI's
disabled state. This prevents unexpected interactions when the UI is
disabled.

resolves https://github.com/emilk/egui/issues/4081 (see discussion
starting from
https://github.com/emilk/egui/issues/3653#issuecomment-1962740175 for
extra context)
this partly restores event-emitting behaviour to the state before #3649,
when shortcuts such as `Ctrl` + `C` used to work regardless of the
active layout. the difference is that physical keys are only used in
case of the logical ones' absence now among the named keys.
while originally I have only limited this to clipboard shortcuts
(Ctrl+C/V/X), honestly it felt like a half-assed solution. as a result,
I decided to expand this behaviour to all key events to stick to the
original logic, in case there are other workflows and hotkeys people
rely on or expect to work out of the box. let me know if this is an
issue.
Removes `egui_assert` etc and replaces it with normal `debug_assert`
calls.
Previously you could opt-in to more runtime checks using feature flags.
Now these extra runtime checks are always enabled for debug builds.
You are most likely to encounter them if you use negative sizes or NaNs
or other similar bugs.
These usually indicate bugs in user space.
updates the wgpu version to 0.20 and changes the API calls accordingly.
I had to update wasm-bindgen to "0.2.92". Otherwise, I got this error
for the demo app:
```

versions that meet the requirements `^0.2.92` are: 0.2.92
all possible versions conflict with previously selected packages.

Why is it locked to this version right now?
I ran the tests, checked the web demo and my own projects, and
everything seems to work fine with wgpu 0.20.

These three types currently have a `Debug` implementation that only ever
prints one decimal point. Sometimes it is useful to see more of the
number, or otherwise have specific formatting.
Add `Display` implementations that pass the format specification to the
member `f32`s for an easier way to control what is shown when debugging.
This allows doing e.g. `ui.label(format!("{:.4}", rect * scale))` which
currently prints zeroes if scale is small.

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.

I had to make a couple types not Copy because closures, but it should'nt
be a massive deal.
I tried my best to make the API change as non breaking as possible.
Anywhere a PathStroke is used, you can just use a normal Stroke instead.
As mentioned above, the bezier paths couldn't be copy anymore, but IMO
that's a minor caveat.

Previously, `SidePanel`/`TopBottomPanel` didn't include `inner_margin`
when setting the min width/height of `Frame`. As a result, when your
`Panel` has `inner_margin`, its size doesn't work as expected.
Before

### 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);
}
```

- Add `Undoer::new()`
- This is necessary to construct an `Undoer` whose `State` parameter
doesn't implement `Default`.
- Add `Undoer::with_settings(...)`
- This is necessary to actually pass settings into the `Undoer`. Without
this, API consumers could construct their own `Settings` but not
actually do anything with it.
I've refrained from adding any kind of builder API for `Settings`
because there are only three options and I don't want to duplicate or
move all the documentation onto the builder methods.
The painter, allocated by `Ui::allocate_painter`, doesn't inherit
properties from the `Ui` object, leading to improper widget rendering in
`egui`.
Specifically, if the `Ui` object is disabled, the corresponding painter
should also be disabled.
The `hex_color!` macro currently makes an unqualified reference to the
`color_hex` crate, which users may not have in their `Cargo.toml`. This
PR re-exports `color_hex` from the root of `ecolor` and changes the
macro to use the re-exported path.

Adds a flag to ScrollArea that disables animations for the scroll_to_*

Usually this isn't visible (the same label being painted on top of
itself), but it will be visible if the user has a custom formatter (e.g.
`y_axis_formatter`) that choses a different format based on
`GridMark:step_size` (e.g. using fewer decimals for thicker ticks).

Changes egui-winit so that it calls `window.set_ime_cursor_area` when
the IME rect changes or the user interacts with the application instead
of calling it every time the app is rendered. This works around a winit
bug that causes the app to continuously repaint under certain
circumstances on Wayland.
Tested on Wayland and on X11 using the text edit in the egui_demo_app -
no changes in IME functionality as far as I can tell. Untested on
non-Linux platforms.

This means only one space allocation, which should allow putting it in
more types of layouts (right-to-left, centered, adjusted, …).
It also just makes the code simpler
`clicked_elsewhere` now checks against the clipped `interact_rect` of
the widget instead of the full `rect`.
In practice this shouldn't change much since the function is mostly used
for windows and areas, which aren't clipped.
This is mostly a refactor, but has some performance benefits:
* We (re)use the same tessellator as for everything else, leading to
less allocations
* We cull shapes before rendering them
Adding `RectShape::blur_width` means it can also be used for other
effects, such as glow.
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

The comment in the code explains it well, but the short of it is this:
we can't handle a shadow blur width larger than the shadow rectangle, so
we need to clamp the blur. This means smaller things will cast shadows
with a smaller blur width, but that's better than having visual
glitches.
Previously, putting the cursor in the gap between two menu buttons would

I'm trying to create some custom collapsing headers that add additional
buttons inside the header itself. Because of this, I load the
`CollapsingState` in my special widget manually. But because
`HeaderResponse` owns the `Ui` and the `CollapsingState`, there is no
way for me to open/close the collapsing header based on response of the
inner widget.
Initially, I considered just exposing `state` member of
`HeaderResponse`, but that exposes too much of the API at the wrong
time, in my opinion.
So instead I found it'd be safer to just expose the open/close API to
the response itself, and that's what this PR does.
Not sure about the api, currently I've mapped the whole XWindowType
enum, but maybe there's something more sensible to do?

I added a handfull of lines to allow for the red highlight on weekends
in `DatePickerPopup` to be disabled.
I tried to follow the rules, but I've never done any kind of PR before,
and I'm also not sure if this is at all the kind of thing that is wanted
at the moment. If it is not, I'm happy to just have this removed. Just a
tiny little addition I would find useful.

Simply allows date picker buttons to show other formats than `%Y-%m-%d`,
while keeping that as default to not break compatibility.
I'm not that experienced with Rust, so I was unsure whether you'd prefer
`&'a str` rather than a `String`, let me know if I should change that.

I believe that the underlying issue that caused the stuck modifier keys
was resolved in the 0.29 winit keyboard refactor.
This probably needs to tested on other desktop platforms however since I
am only able to test this on windows 11.
* Closes <https://github.com/emilk/egui/issues/2332>
* Closes https://github.com/emilk/egui/issues/3444
* Closes https://github.com/emilk/egui/issues/865
On a touch screen, if you press down on a widget and hold for 0.6
seconds (`MAX_CLICK_DURATION`), it will now trigger a secondary click,
i.e. `Response::secondary_clicked` will be `true`. This means you can
now open context menus on touch screens.
This is a refactor on the way to add support for opening context menus
on touch screens via press-and-hold.
This PR changes what `InputState::button_clicked` does (it was ver badly
named before), and also changes `Response::clicked_by` to no longer be
true if clicking with keyboard (i.e. a widget has keyboard focus and the
user presses Space or Enter).
This PR fixes two issues related to `ScrollArea`.
1) When a `ScrollArea` would have `drag_to_scroll` set to `false` (e.g.
because some custom logic is at play or some other reason), it would not
animate to the `target_offset`, effectively making
`Response::scroll_to_me()` ineffective.
2) Single-direction `ScrollArea`s would leak the `scroll_target`'s other
direction. In certain specific circumstances (e.g. an horizontal area
nested in a vertical one, or inversely), this _could_ work as intended,
but in many other cases it could cause unwanted effects. With this PR,
both `scroll_target` directions are consumed by nearest enclosing
`ScrollArea`, regardless of the actually enabled scroll axes.
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.

Dear emilk.
Leaving aside other function,
I think this is all you need to fix to patch the panic that occurs when
Shift + TAB.
Thank you, emilk.
Hi!
I'm using egui for the UI of a VST3/Clap plugin, and this kind of
environment is rather picky on performance. I use
[assert_no_alloc](https://crates.io/crates/assert_no_alloc) to make sure
the audio thread is never allocating. The audio thread may request a
repaint of the GUI tho, and this is where a saw that it may allocate
when tracing the repaint reason.
Turns out it's not necessary, `Location::caller` is `'static`, so using
a `&'static str` instead of a `String` in `RepaintCause::file` will just
work, so this PR just does that.
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.
When scaling an `egui::Shape` of variant `Rect` using the new
`transform` function, corner rounding isn't taken into account.
The fix is to multiply the rounding by the scaling factor.
* Closes <https://github.com/emilk/egui/issues/4152>
# 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.

* Remove the leading slash from the path if the target OS is Windows.
This is because Windows paths are not supposed to start with a slash.
For example, `file:///C:/path/to/file` is a valid URI, but
`/C:/path/to/file` is not a valid path.
* Use the input URI consistently as the cache key.
Currently, the cache key is inconsistently set as either the path or the
URI, while the forget key is always the URI. This inconsistency should
be resolved.

The `Shape::translate` method has been replaced with `Shape::transform`,
which introduces breaking changes that could negatively impact existing
users.
This patch adds a `Shape::translate` wrapper to prevent these breaking
changes.
- Introduces `WidgetType::ProgressIndicator` and maps it to the
corresponding AccessKit role.
- A `Spinner` is now exposed as a widget indicating a progress for which
a completion state is not known.
- On the other hand, a `ProgressBar` reports a completion state and can
possibly be labeled. Note that a label is not used if not explicitly
asked by the user, as it would be redundant information. Assistive
technologies prefer the numerical value so they can, for instance, emit
beeps of which the frequency rise as the completion state increase. I
had to call `floor` on the progression as it seems all the ATs I tested
would round the value, hence reporting something different than what is
displayed on the label.
* Closes https://github.com/emilk/egui/issues/4113
Previously the `Id` of the menu `Area` was using the same id as the
thing that was clicked (i.e. the button opening menu), which lead to id
clashes
We plan to store input data for creating automated tests, hence the need
for more serde derives on input related structs.

I often write constants at the top of my widget files, as a "config". I
kept writing stuff like that :
```rust
const DEFAULT_INNER_MARGIN: Margin = Margin { left: 17., right: 17., top: 7., bottom: 7. };
```
So I prefixed constructors for `Margin`, `Rounding` and `Shadow` const.
No code was changed.
I also added a `Shadow::new()` for similar reasons.
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
Add an alternative method for creating a [`ColorImage`] that accepts
`Iterator` as the argument. It can be useful when `&[u8]` is not
available but the iterator is.
