Fix incorrect window sizes for non-resizable windows on Wayland (#7103)
Using physical window sizes leads to all kinds of fun stuff: winit
always uses scale factor 1.0 on start to convert it back to logical
pixels and uses these logical pixels to set min/max size for
non-resizeable windows. You're supposed to adjust size after getting a
scale change event if you're using physical sizes, but adjusting min/max
sizes doesn't seem to work on sway, so the window is stuck with an
incorrect size.

The scale factor we guessed might also be wrong even if there's only a
single display since it doesn't take fractional scale into account.

TL;DR: winit actually wants logical sizes in these methods (since
Wayland in general operates mostly on logical sizes) and converting them
back and forth is lossy.

Support for Back button Key on Android (#7073)
When your press a Back button on Android (for example at
`native-activity`), [Winit translates this
key](47b938dbe7/src/platform_impl/android/keycodes.rs (L237C42-L237C53))
as `NamedKey::BrowserBack`. Added convertion to `Key::Escape` at

Add macOS-specific `has_shadow` and `with_has_shadow` to ViewportBuilder (#6850)
* [X] I have followed the instructions in the PR template

This PR fixes a ghosting issue I encountered while making a native macOS
transparent overlay app using egui and eframe by exposing the [existing
macOS window attribute
`has_shadow`](https://docs.rs/winit/latest/winit/platform/macos/trait.WindowExtMacOS.html#tymethod.has_shadow)
to the `ViewportBuilder` via a new `with_has_shadow` option.

## Example of Ghosting Issue

### Before `ViewportBuilder::with_has_shadow`
By default, the underlying `winit` window's `.has_shadow()` defaults to
`true`.


https://github.com/user-attachments/assets/c3dcc2bd-535a-4960-918e-3ae5df503b12

### After `ViewportBuilder::with_has_shadow`


https://github.com/user-attachments/assets/484462a1-ea88-43e6-85b4-0bb9724e5f14

Source code for the above example can be found here:

https://github.com/gaelanmcmillan/egui-overlay-app-with-shadow-artifacts-example/blob/main/src/main.rs


### Further background
By default on macOS, `winit` windows have a drop-shadow effect. When
creating a fully transparent overlay GUI, this drop-shadow can create a
ghosting effect, as the window content has a drop shadow which is not
cleared by the app itself. This issue has been experienced by users of
`bevy`, another Rust project that has an upstream dependency on `winit`:

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.

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

Keep track of why `request_discard` was called (#5134)
This will help debug spurious calls to it
2024-09-20 09:17:52 +02:00
Emil Ernerfeldt 66076101e1
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
* [x] Show warning on screen when there are several frames in a row with
multiple passes
* [x] Document
* [x] Default on or off?
* [x] Change `Context::frame_nr` name/docs
* [x] Rename `Context::begin_frame/end_frame` and deprecate the old ones
* [x] Test with Rerun
* [x] Document breaking changes

Upgrade winit to 0.30.2 (#4849)
* Closes https://github.com/emilk/egui/issues/1918

* Closes https://github.com/emilk/egui/issues/4709

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!

It was surprising to me that this key wasn't sending `Event::Key` events
(only `Event::Text`), so I added a `Key` for it.

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.

### 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.

egui-winit: emit physical key presses when a non-Latin layout is active (#4461)
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.

### simple example

```rust
pub struct MyApp {}

impl MyApp {
    pub fn new() -> MyApp {
        MyApp {}
    }
}

impl eframe::App for MyApp {
    fn update(&mut self, ctx: &Context, frame: &mut eframe::Frame) {
        egui::CentralPanel::default()
            .frame(Frame::none().fill(Color32::DARK_GRAY))
            .show(ctx, |ui| {
                if ctx.input(|i| i.key_pressed(Key::Escape)) {
                    ctx.send_viewport_cmd(ViewportCommand::Close);
                }
            });
    }
}

pub fn main() {
    let option = eframe::NativeOptions {
        viewport: ViewportBuilder::default()
            .with_position([10.0, 10.0])
            .with_inner_size([3000.0, 2000.0])
            .with_clamp_size_to_monitor_size(false),
        ..Default::default()
    };

    eframe::run_native(
        "a large window app",
        option,
        Box::new(|ctx| Box::new(MyApp::new())),
    ).unwrap();
}
```

It works on my windows (with 3 monitors), but I don't have a test
environment for macos

Add `ViewportCommand::RequestCut`, `RequestCopy` and `RequestPaste` to trigger Clipboard actions (#4035)
### 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);
}
```

Fix continuous repaint on Wayland when TextEdit is focused or IME output is not None (#4269)
* Closes #4254

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.

Add API for raw mouse motion (#4063)
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
