* Web: only capture clicks/touches when actually over canvas [#4775](https://github.com/emilk/egui/pull/4775) by [@lucasmerlin](https://github.com/lucasmerlin)
## 0.28.0 - 2024-07-03 - Better integration of a eframe in a bigger website
### ✨ Highlights
The eframe web canvas now works properly when its a small part of a larger web page.
Previously this caused a lot of weird bugs, such as the eframe canvas stealing focus, and resizing the canvas in annoying ways.
Now it should all work seamlessly to have an eframe canvas as part of a web page, including having multiple different eframe apps next to each other.
As part of that the eframe canvas can now be focused (or not), just like an `<input>` HTML element.
We've also implemented a better method for sizing and positioning the canvas so that it yields pixel-perfect rendering on all known browsers except for Desktop Safari.
What this means is that text is much less likely to be blurry on web for users ([#4536](https://github.com/emilk/egui/pull/4536) by [@jprochazk](https://github.com/jprochazk)).

#### Wrap app creator in a `Result`
Applications can now return an error during the app creation ([#4565](https://github.com/emilk/egui/pull/4565) by [@emilk](https://github.com/emilk)), so you now need to wrap your `Box<dyn App>` in a `Result` like so:
``` diff
- eframe::run_native("My App", options, Box::new(|cc| Box::new(MyApp::new(cc))));
+ eframe::run_native("My App", options, Box::new(|cc| Ok(Box::new(MyApp::new(cc)))));
```
#### Change web CSS
To make the eframe canvas fill the entire web browser, set its CSS to:
``` css
top: 0;
left: 0;
width: 100%;
height: 100%;
```
See [`index.html`](https://github.com/emilk/egui/blob/a489374ca63f0d1ae983bb21d8bb766b2d68737b/web_demo/index.html#L30-L50) and [#4536](https://github.com/emilk/egui/pull/4536) for details.
#### Web canvas focus
If you are using eframe for a fullscreen app, you should call `.focus()` on your canvas during startup:
```js
document.getElementById("the_canvas_id").focus();
```

* Update MSRV to Rust 1.72 [#3595](https://github.com/emilk/egui/pull/3595)
### Breaking changes:
Most settings in `NativeOptions` have been moved to `NativeOptions::viewport`, which uses the new `egui::ViewportBuilder`:
```diff
let native_options = eframe::nativeOptions {
- initial_window_size: Some(egui::vec2(320.0, 240.0)),
- drag_and_drop_support: true,
+ viewport: egui::ViewportBuilder::default()
+ .with_inner_size([320.0, 240.0])
+ .with_drag_and_drop(true),
..Default::default()
};
```
`NativeOptions::fullsize_content` has been replaced with four settings: `ViewportBuilder::with_fullsize_content_view`, `with_title_shown`, `with_titlebar_shown`, `with_titlebar_buttons_shown`
`frame.info().window_info` is gone, replaced with `ctx.input(|i| i.viewport())`.
`frame.info().native_pixels_per_point` is replaced with `ctx.input(|i| i.raw.native_pixels_per_point)`.
Most commands in `eframe::Frame` has been replaced with `egui::ViewportCommand`, so So `frame.close()` becomes `ctx.send_viewport_cmd(ViewportCommand::Close)`, etc.
`App::on_close_event` has been replaced with `ctx.input(|i| i.viewport().close_requested())` and `ctx.send_viewport_cmd(ViewportCommand::CancelClose)`.
`eframe::IconData` is now `egui::IconData`.
`eframe::IconData::try_from_png_bytes` is now `eframe::icon_data::from_png_bytes`.
`App::post_rendering` is gone. Screenshots are taken with `ctx.send_viewport_cmd(ViewportCommand::Screenshots)` and are returned in `egui::Event` which you can check with:
``` rust
ui.input(|i| {
for event in &i.raw.events {
if let egui::Event::Screenshot { viewport_id, image } = event {
// handle it here
}
}
});
```
