This allows customizing the persistence path in NativeOptions.
Previously, persistence wouldn't work with android because
directories-next doesn't support android so eframe would just fail to
find a place where it could store its config.
* Closes#4098 (android users can now specify a path that works with
android, by e.g. using app_dirs2, which supports android)
Simply adds a `hint_text_font` (any suggestions for a better name?
hint_text_style seemed misleading as it doesn't only accept `TextStyle`)
method to the TextEdit builder that allows to set the styling
(specifically, a `FontSelection`) for the hint text.
My personal use-case for this was having body-sized hint text in a
heading-sized TextEdit, but I'm sure there's more out there.
The PR shouldn't break compatibility, as it's stored as an `Option` that
defaults to the `font_id` (which was the only behaviour prior to this)
when empty.
It looked too trivial to add something to the actual demo, but I have it
locally, so let me know if I should commit that.
Ran the check script locally, had no complaints.
I wanted to disable the return key functionality on my `TextEdit`, so
that the `TextEdit` doesn't get unfocused whenever the user submits a
command onto my developer console (which is also bound to <kbd>↵
Enter</kbd>).

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.
I wanted to implement a font picker that loads all system fonts but ran
into panics due to missing glyphs. Falling back to an empty glyph when
none of the fallback glyphs are available avoids the panic.

You can zoom in using ctrl/cmd + scrolling. When using a discreet scroll
wheel, the zoom factor now gets smoothed.
For integrations: just emit `egui::Event::MouseWheel` (like before).
egui will interpret that as zoom or pan.
On the way towards https://github.com/emilk/egui/issues/4401
* Closes https://github.com/emilk/egui/issues/4434
Shouldn't break anything, because when all arguments have a 'static
lifetime (required without this PR), the Plot is also 'static and can be
used like before.

Inspired by:

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.
Closes#4341

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:
```
error: failed to select a version for `wasm-bindgen`.
... required by package `js-sys v0.3.69`
... which satisfies dependency `js-sys = "^0.3.69"` of package `eframe v0.27.2 (/home/user/Projects/egui/crates/eframe)`
... which satisfies path dependency `eframe` (locked to 0.27.2) of package `confirm_exit v0.1.0 (/home/user/Projects/egui/examples/confirm_exit)`
versions that meet the requirements `^0.2.92` are: 0.2.92
all possible versions conflict with previously selected packages.
previously selected package `wasm-bindgen v0.2.90`
... which satisfies dependency `wasm-bindgen = "=0.2.90"` of package `egui_demo_app v0.27.2 (/home/user/Projects/egui/crates/egui_demo_app)`
failed to select a version for `wasm-bindgen` which could resolve this conflict
```
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.

Added clamp_size_to_monitor_size field on ViewportBuilder, which means
whether clamp the window's size to monitor's size. (default to `true`)
* Closes https://github.com/emilk/egui/issues/3389
### 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
