Currently Bevy's web canvases are "fixed size". They are manually set to specific dimensions. This might be fine for some games and website layouts, but for sites with flexible layouts, or games that want to "fill" the browser window, Bevy doesn't provide the tools needed to make this easy out of the box.
There are third party plugins like [bevy-web-resizer](https://github.com/frewsxcv/bevy-web-resizer/) that listen for window resizes, take the new dimensions, and resize the winit window accordingly. However this only covers a subset of cases and this is common enough functionality that it should be baked into Bevy.
A significant motivating use case here is the [Bevy WASM Examples page](https://bevyengine.org/examples/). This scales the canvas to fit smaller windows (such as mobile). But this approach both breaks winit's mouse events and removes pixel-perfect rendering (which means we might be rendering too many or too few pixels). https://github.com/bevyengine/bevy-website/issues/371
In an ideal world, winit would support this behavior out of the box. But unfortunately that seems blocked for now: https://github.com/rust-windowing/winit/pull/2074. And it builds on the ResizeObserver api, which isn't supported in all browsers yet (and is only supported in very new versions of the popular browsers).
While we wait for a complete winit solution, I've added a `fit_canvas_to_parent` option to WindowDescriptor / Window, which when enabled will listen for window resizes and resize the Bevy canvas/window to fit its parent element. This enables users to scale bevy canvases using arbitrary CSS, by "inheriting" their parents' size. Note that the wrapper element _is_ required because winit overrides the canvas sizing with absolute values on each resize.
There is one limitation worth calling out here: while the majority of canvas resizes will be triggered by window resizes, modifying element layout at runtime (css animations, javascript-driven element changes, dev-tool-injected changes, etc) will not be detected here. I'm not aware of a good / efficient event-driven way to do this outside of the ResizeObserver api. In practice, window-resize-driven canvas resizing should cover the majority of use cases. Users that want to actively poll for element resizes can just do that (or we can build another feature and let people choose based on their specific needs).
I also took the chance to make a couple of minor tweaks:
* Made the `canvas` window setting available on all platforms. Users shouldn't need to deal with cargo feature selection to support web scenarios. We can just ignore the value on non-web platforms. I added documentation that explains this.
* Removed the redundant "initial create windows" handler. With the addition of the code in this pr, the code duplication was untenable.
This enables a number of patterns:
## Easy "fullscreen window" mode for the default canvas
The "parent element" defaults to the `<body>` element.
```rust
app
.insert_resource(WindowDescriptor {
fit_canvas_to_parent: true,
..default()
})
```
And CSS:
```css
html, body {
margin: 0;
height: 100%;
}
```
## Fit custom canvas to "wrapper" parent element
```rust
app
.insert_resource(WindowDescriptor {
fit_canvas_to_parent: true,
canvas: Some("#bevy".to_string()),
..default()
})
```
And the HTML:
```html
<div style="width: 50%; height: 100%">
<canvas id="bevy"></canvas>
</div>
```
# Objective
Fixes#3180, builds from https://github.com/bevyengine/bevy/pull/2898
## Solution
Support requesting a window to be closed and closing a window in `bevy_window`, and handle this in `bevy_winit`.
This is a stopgap until we move to windows as entites, which I'm sure I'll get around to eventually.
## Changelog
### Added
- `Window::close` to allow closing windows.
- `WindowClosed` to allow reacting to windows being closed.
### Changed
Replaced `bevy::system::exit_on_esc_system` with `bevy:🪟:close_on_esc`.
## Fixed
The app no longer exits when any window is closed. This difference is only observable when there are multiple windows.
## Migration Guide
`bevy::input::system::exit_on_esc_system` has been removed. Use `bevy:🪟:close_on_esc` instead.
`CloseWindow` has been removed. Use `Window::close` instead.
The `Close` variant has been added to `WindowCommand`. Handle this by closing the relevant window.
What is says on the tin.
This has got more to do with making `clippy` slightly more *quiet* than it does with changing anything that might greatly impact readability or performance.
that said, deriving `Default` for a couple of structs is a nice easy win
# Objective
Enable the user to specify any presentation modes (including `Mailbox`).
Fixes#3807
## Solution
I've added a new `PresentMode` enum in `bevy_window` that mirrors the `wgpu` enum 1:1. Alternatively, I could add a new dependency on `wgpu-types` if that would be preferred.
Implements the changes cart decided on in https://github.com/bevyengine/bevy/pull/3404#issuecomment-999806086
> - The default title should be changed to app so we don't leak the "bevy context" by default. app is generic enough that most people building real games will probably want to change it, but also generic enough that if someone doesn't manually set it, users won't bat an eye. I prefer this to binary names because they won't be consistent on all platforms / setups. A user (or developer) renaming a binary would implicitly rename the window title, which feels odd to me.
> - No debug info in the title by default. An opt in plugin for that would be nice though.
closes#3404 ?
# Objective
CI should check for missing backticks in doc comments.
Fixes#3435
## Solution
`clippy` has a lint for this: `doc_markdown`. This enables that lint in the CI script.
Of course, enabling this lint in CI causes a bunch of lint errors, so I've gone through and fixed all of them. This was a huge edit that touched a ton of files, so I split the PR up by crate.
When all of the following are merged, the CI should pass and this can be merged.

# Objective
The window's cursor should be settable without having to implement a custom cursor icon solution. This will especially be helpful when creating user-interfaces that might like to use the cursor to denote some meaning (e.g., _clickable_, _resizable_, etc.).
## Solution
Added a `CursorIcon` enum that maps one-to-one to winit's `CursorIcon` enum, as well as a method to set/get it for the given `Window`.
# Objective
- There are a few warnings when building Bevy docs for dead links
- CI seems to not catch those warnings when it should
## Solution
- Enable doc CI on all Bevy workspace
- Fix warnings
- Also noticed plugin GilrsPlugin was not added anymore when feature was enabled
First commit to check that CI would actually fail with it: https://github.com/bevyengine/bevy/runs/4532652688?check_suite_focus=true

# Objective
- there are a few new versions for `ron`, `winit`, `ndk`, `raw-window-handle`
- `cargo-deny` is failing due to new security issues / duplicated dependencies
## Solution
- Update our dependencies
- Note all new security issues, with which of Bevy direct dependency it comes from
- Update duplicate crate list, with which of Bevy direct dependency it comes from
`notify` is not updated here as it's in #2993
Applogies, had to recreate this pr because of branching issue.
Old PR: https://github.com/bevyengine/bevy/pull/3033
# Objective
Fixes#3032
Allowing a user to create a transparent window
## Solution
I've allowed the transparent bool to be passed to the winit window builder
This pull request aims to solve the issue of a lack of documentation in the enum WindowMode
# Objective
- Fixes#3136
## Solution
- Added a few lines of documentation that should document what the enum does better
# Objective
Set initial position of the window, so I can start it at the left side of the view automatically, used with `cargo watch`
## Solution
add window position to WindowDescriptor
# Objective
- Fixes#2501
- Builds up on #2639 taking https://github.com/bevyengine/bevy/pull/2639#issuecomment-898701047 into account
## Solution
- keep the physical cursor position in `Window`, and expose it.
- still convert to logical position in event, and when getting `cursor_position`
Co-authored-by: Ahmed Charles <acharles@outlook.com>
This alias is to aid people finding the cursor_position function, as the mouse
pressed / moved functionality and naming likely primes people for thinking
of "mouse" before "cursor" when searching the api documentation.
Many a game will provide some sort of video settings where a window mode option is a common inclusion. I ran into problems, however, with [egui's](https://github.com/emilk/egui) `combo_box` that imposes a `PartialEq` necessity. Deriving the trait would fix this problem, and as this does not break any existing API it should be a non-controversial change.
You should be able to set the minimum and maximum desired resolution of a system window.
This also fixes a bug on Windows operating system: When you try to resize to 0 on the height it crashes.

* Simple Implementation to address #1327 by adding a focused field to the window and related system
* Changing Window update function from bevy_window to bevy_winit.
* Removing unused imports.
