# Changelog
|
||||
|
||||
All notable changes to this project will be documented in this file.
|
||||
|
||||
Please keep one empty line before and after all headers. (This is required for `git` to produce a conflict when a release is made while a PR is open and the PR's changelog entry would go into the wrong section).
|
||||
|
||||
And please only add new entries to the top of this list, right below the `# Unreleased` header.
|
||||
|
||||
# Unreleased
|
||||
|
||||
# 0.28.6
|
||||
# Version 0.19.2 (2019-07-29)

|
||||
|
||||
# 0.28.5
|
||||
|
||||
- On macOS, fix `key_up` beind ignored when `Ime` is disabled.
|
||||
|
||||
# 0.28.4
|
||||
|
||||
- On macOS, fix empty marked text blocking regular input.
|
||||
- On macOS, fixed potential panic when getting refresh rate.
|
||||
- On macOS, fix crash when calling `Window::set_ime_position` from another thread.
|
||||
- On macOS, fixed memory leak when getting monitor handle.
|
||||
|
||||
# 0.28.3
|
||||
|
||||
- Fix macOS memory leaks.
|
||||
|
||||
# 0.28.2
|
||||
|
||||
- Implement `HasRawDisplayHandle` for `EventLoop`.
|
||||
- On macOS, set resize increments only for live resizes.
|
||||
- On Wayland, fix rare crash on DPI change
|
||||
- Web: Added support for `Window::theme`.
|
||||
- On Wayland, fix rounding issues when doing resize.
|
||||
- On macOS, fix wrong focused state on startup.
|
||||
- On Windows, fix crash on setting taskbar when using Visual Studio debugger.
|
||||
- On macOS, resize simple fullscreen windows on windowDidChangeScreen events.
|
||||
|
||||
# 0.28.1
|
||||
|
||||
- On Wayland, fix crash when dropping a window in multi-window setup.
|
||||
|
||||
# 0.28.0
|
||||
|
||||
- On macOS, fixed `Ime::Commit` persisting for all input after interacting with `Ime`.
|
||||
- On macOS, added `WindowExtMacOS::option_as_alt` and `WindowExtMacOS::set_option_as_alt`.
|
||||
- On Windows, fix window size for maximized, undecorated windows.
|
||||
- On Windows and macOS, add `WindowBuilder::with_active`.
|
||||
- Add `Window::is_minimized`.
|
||||
- On X11, fix errors handled during `register_xlib_error_hook` invocation bleeding into winit.
|
||||
- Add `Window::has_focus`.
|
||||
- On Windows, fix `Window::set_minimized(false)` not working for windows minimized by `Win + D` hotkey.
|
||||
- **Breaking:** On Web, touch input no longer fires `WindowEvent::Cursor*`, `WindowEvent::MouseInput`, or `DeviceEvent::MouseMotion` like other platforms, but instead it fires `WindowEvent::Touch`.
|
||||
- **Breaking:** Removed platform specific `WindowBuilder::with_parent` API in favor of `WindowBuilder::with_parent_window`.
|
||||
- On Windows, retain `WS_MAXIMIZE` window style when un-minimizing a maximized window.
|
||||
- On Windows, fix left mouse button release event not being sent after `Window::drag_window`.
|
||||
- On macOS, run most actions on the main thread, which is strictly more correct, but might make multithreaded applications block slightly more.
|
||||
- On macOS, fix panic when getting current monitor without any monitor attached.
|
||||
- On Windows and MacOS, add API to enable/disable window buttons (close, minimize, ...etc).
|
||||
- On Windows, macOS, X11 and Wayland, add `Window::set_theme`.
|
||||
- **Breaking:** Remove `WindowExtWayland::wayland_set_csd_theme` and `WindowBuilderExtX11::with_gtk_theme_variant`.
|
||||
- On Windows, revert window background to an empty brush to avoid white flashes when changing scaling.
|
||||
- **Breaking:** Removed `Window::set_always_on_top` and related APIs in favor of `Window::set_window_level`.
|
||||
- On Windows, MacOS and X11, add always on bottom APIs.
|
||||
- On Windows, fix the value in `MouseButton::Other`.
|
||||
- On macOS, add `WindowExtMacOS::is_document_edited` and `WindowExtMacOS::set_document_edited` APIs.
|
||||
- **Breaking:** Removed `WindowBuilderExtIOS::with_root_view_class`; instead, you should use `[[view layer] addSublayer: ...]` to add an instance of the desired layer class (e.g. `CAEAGLLayer` or `CAMetalLayer`). See `vulkano-win` or `wgpu` for examples of this.
|
||||
- On MacOS and Windows, add `Window::set_content_protected`.
|
||||
- On MacOS, add `EventLoopBuilderExtMacOS::with_activate_ignoring_other_apps`.
|
||||
- On Windows, fix icons specified on `WindowBuilder` not taking effect for windows created after the first one.
|
||||
- On Windows and macOS, add `Window::title` to query the current window title.
|
||||
- On Windows, fix focusing menubar when pressing `Alt`.
|
||||
- On MacOS, made `accepts_first_mouse` configurable.
|
||||
- Migrated `WindowBuilderExtUnix::with_resize_increments` to `WindowBuilder`.
|
||||
- Added `Window::resize_increments`/`Window::set_resize_increments` to update resize increments at runtime for X11/macOS.
|
||||
- macOS/iOS: Use `objc2` instead of `objc` internally.
|
||||
- **Breaking:** Bump MSRV from `1.57` to `1.60`.

# 0.20.0 Alpha 1 (2019-06-21)
|
||||
|
||||
- Changes below are considered **breaking**.
|
||||
- Change all occurrences of `EventsLoop` to `EventLoop`.
|
||||
- Previously flat API is now exposed through `event`, `event_loop`, `monitor`, and `window` modules.
|
||||
- `os` module changes:
|
||||
- Renamed to `platform`.
|
||||
- All traits now have platform-specific suffixes.

||||
- Exposes new `desktop` module on Windows, Mac, and Linux.
|
||||
- Changes to event loop types:

||||
- `EventLoopProxy::wakeup` has been removed in favor of `send_event`.
|
||||
- **Major:** New `run` method drives winit event loop.
|
||||
- Returns `!` to ensure API behaves identically across all supported platforms.
|
||||
- This allows `emscripten` implementation to work without lying about the API.
|
||||
- `ControlFlow`'s variants have been replaced with `Wait`, `WaitUntil(Instant)`, `Poll`, and `Exit`.
|
||||
- Is read after `EventsCleared` is processed.
|
||||
- `Wait` waits until new events are available.
|
||||
- `WaitUntil` waits until either new events are available or the provided time has been reached.
|
||||
- `Poll` instantly resumes the event loop.
|
||||
- `Exit` aborts the event loop.
|
||||
- Takes a closure that implements `'static + FnMut(Event<T>, &EventLoop<T>, &mut ControlFlow)`.
|
||||
- `&EventLoop<T>` is provided to allow new `Window`s to be created.
|
||||
- **Major:** `platform::desktop` module exposes `EventLoopExtDesktop` trait with `run_return` method.
|
||||
- Behaves identically to `run`, but returns control flow to the calling context and can take non-`'static` closures.
|
||||
- `EventLoop`'s `poll_events` and `run_forever` methods have been removed in favor of `run` and `run_return`.
|
||||
- Changes to events:

|
||||
- Can be sent with `EventLoopProxy::send_event`.

|
||||
- `RedrawRequested` can be sent by the user with the `Window::request_redraw` method.
|
||||
- `EventLoop`, `EventLoopProxy`, and `Event` are now generic over `T`, for use in `UserEvent`.
|
||||
- **Major:** Add `NewEvents(StartCause)`, `EventsCleared`, and `LoopDestroyed` variants to `Event`.
|
||||
- `NewEvents` is emitted when new events are ready to be processed by event loop.
|
||||
- `StartCause` describes why new events are available, with `ResumeTimeReached`, `Poll`, `WaitCancelled`, and `Init` (sent once at start of loop).
|
||||
- `EventsCleared` is emitted when all available events have been processed.
|
||||
- Can be used to perform logic that depends on all events being processed (e.g. an iteration of a game loop).
|
||||
- `LoopDestroyed` is emitted when the `run` or `run_return` method is about to exit.
|
||||
- Rename `MonitorId` to `MonitorHandle`.
|
||||
- Removed `serde` implementations from `ControlFlow`.
|
||||
- Rename several functions to improve both internal consistency and compliance with Rust API guidelines.
|
||||
- Remove `WindowBuilder::multitouch` field, since it was only implemented on a few platforms. Multitouch is always enabled now.
|
||||
- **Breaking:** On macOS, change `ns` identifiers to use snake_case for consistency with iOS's `ui` identifiers.
|
||||
- Add `MonitorHandle::video_modes` method for retrieving supported video modes for the given monitor.
|
||||
- On Wayland, the window now exists even if nothing has been drawn.
|
||||
- On Windows, fix initial dimensions of a fullscreen window.
|
||||
- On Windows, Fix transparent borderless windows rendering wrong.

- your patch builds with Winit's minimal supported rust version - Rust 1.60.
|

- you tested your modifications on all the platforms impacted, or if not possible detail which platforms

were not tested, and what should be tested, so that a maintainer or another contributor can test them

is that a PR must be approved by at least two maintainers of winit before being merged, including

at least a maintainer of the platform (a maintainer making a PR themselves counts as approving it).
|
||||
|

Once your PR is deemed ready, the merging maintainer will take care of resolving conflicts in

`CHANGELOG.md` (but you must resolve other conflicts yourself). Doing this requires that you check the

## Maintainers & Testers
|
||||
|
||||
The current maintainers are listed in the [CODEOWNERS](.github/CODEOWNERS) file.
|
||||
Winit is managed by several people, each with their specialities, and each maintaining a subset of the
|
||||
backends of winit. As such, depending on your platform of interest, your contacts will be different.
|
||||
|
||||
If you are interested in being pinged when testing is needed for a certain platform, please add yourself to the [Testers and Contributors](https://github.com/rust-windowing/winit/wiki/Testers-and-Contributors) table!
|
||||
This table summarizes who can be contacted in which case, with the following legend:
|
||||
|
||||
## Release process
|
||||
- `M` - Maintainer: is a main maintainer for this platform
|
||||
- `C` - Collaborator: can review code and address issues on this platform
|
||||
- `T` - Tester: has the ability of testing the platform
|
||||
- ` `: knows nothing of this platform
|
||||
|
||||
Given that winit is a widely used library we should be able to make a patch
|
||||
releases at any time we want without blocking the development of new features.
|
||||
|
||||
To achieve these goals, a new branch is created for every new release. Releases
|
||||
and later patch releases are committed and tagged in this branch.
|
||||
|
||||
The exact steps for an exemplary `0.2.0` release might look like this:
|
||||
1. Initially the version on the latest master is `0.1.0`
|
||||
2. A new `v0.2.x` branch is created for the release
|
||||
3. In the branch, the version is bumped to `v0.2.0`
|
||||
4. The new commit in the branch is tagged `v0.2.0`
|
||||
5. The version is pushed to crates.io
|
||||
6. A GitHub release is created for the `v0.2.0` tag
|
||||
7. On master, the version is bumped to `0.2.0` and the CHANGELOG is updated
|
||||
|
||||
When doing a patch release the process is similar:
|
||||
1. Initially the version of the latest release is `0.2.0`
|
||||
2. Checkout the `v0.2.x` branch
|
||||
3. Cherry-pick the required non-breaking changes into the `v0.2.x`
|
||||
4. Follow steps 3-7 of the regular release example

### Cargo Features
|
||||
|
||||
Winit provides the following features, which can be enabled in your `Cargo.toml` file:
|
||||
* `icon_loading`: Enables loading window icons directly from files. Depends on the [`image` crate](https://crates.io/crates/image).
|
||||
* `serde`: Enables serialization/deserialization of certain types with [Serde](https://crates.io/crates/serde).
|
||||
* `x11` (enabled by default): On Unix platform, compiles with the X11 backend
|
||||
* `wayland` (enabled by default): On Unix platform, compiles with the Wayland backend
|
||||
* `mint`: Enables mint (math interoperability standard types) conversions.
|
||||
|
||||
### Platform-specific usage
|
||||
|
||||
#### Wayland
|
||||
#### Emscripten and WebAssembly
|
||||
|
||||
Note that windows don't appear on Wayland until you draw/present to them.
|
||||
Building a binary will yield a `.js` file. In order to use it in an HTML file, you need to:
|
||||
|
||||
`winit` doesn't do drawing, try the examples in [`glutin`] instead.
|
||||
|
||||
[`glutin`]: https://github.com/rust-windowing/glutin
|
||||
|
||||
#### WebAssembly
|
||||
|
||||
To run the web example: `cargo run-wasm --example web`
|
||||
|
||||
Winit supports compiling to the `wasm32-unknown-unknown` target with `web-sys`.
|
||||
|
||||
On the web platform, a Winit window is backed by a `<canvas>` element. You can
|
||||
either [provide Winit with a `<canvas>` element][web with_canvas], or [let Winit
|
||||
create a `<canvas>` element which you can then retrieve][web canvas getter] and
|
||||
insert it into the DOM yourself.
|
||||
|
||||
For example code using Winit with WebAssembly, check out the [web example]. For
|
||||
information on using Rust on WebAssembly, check out the [Rust and WebAssembly
|
||||
book].

|
||||
|
||||
#### Android
|
||||
|
||||
The Android backend builds on (and exposes types from) the [`ndk`](https://docs.rs/ndk/0.7.0/ndk/) crate.
|
||||
|
||||
Native Android applications need some form of "glue" crate that is responsible
|
||||
for defining the main entry point for your Rust application as well as tracking
|
||||
various life-cycle events and synchronizing with the main JVM thread.
|
||||
|
||||
Winit uses the [android-activity](https://github.com/rib/android-activity) as a
|
||||
glue crate (prior to `0.28` it used
|
||||
[ndk-glue](https://github.com/rust-windowing/android-ndk-rs/tree/master/ndk-glue)).
|
||||
|
||||
The version of the glue crate that your application depends on _must_ match the
|
||||
version that Winit depends on because the glue crate is responsible for your
|
||||
application's main entrypoint. If Cargo resolves multiple versions they will
|
||||
clash.
|
||||
|
||||
`winit` glue compatibility table:
|
||||
|
||||
| winit | ndk-glue |
|
||||
| :---: | :--------------------------: |
|
||||
| 0.28 | `android-activity = "0.4"` |
|
||||
| 0.27 | `ndk-glue = "0.7"` |
|
||||
| 0.26 | `ndk-glue = "0.5"` |
|
||||
| 0.25 | `ndk-glue = "0.3"` |
|
||||
| 0.24 | `ndk-glue = "0.2"` |
|
||||
|
||||
The recommended way to avoid a conflict with the glue version is to avoid explicitly
|
||||
depending on the `android-activity` crate, and instead consume the API that
|
||||
is re-exported by Winit under `winit::platform::android::activity::*`
|
||||
|
||||
Running on an Android device needs a dynamic system library, add this to Cargo.toml:
|
||||
|
||||
```toml
|
||||
[lib]
|
||||
name = "main"
|
||||
crate-type = ["cdylib"]
|
||||
```
|
||||
|
||||
All Android applications are based on an `Activity` subclass and the
|
||||
`android-activity` crate is designed to support different choices for this base
|
||||
class. Your application _must_ specify the base class it needs via a feature flag:
|
||||
|
||||
| Base Class | Feature Flag | Notes |
|
||||
| :--------------: | :---------------: | :-----: |
|
||||
| `NativeActivity` | `android-native-activity` | Built-in to Android - it is possible to use without compiling any Java or Kotlin code. Java or Kotlin code may be needed to subclass `NativeActivity` to access some platform features. It does not derive from the [`AndroidAppCompat`] base class.|
|
||||
| [`GameActivity`] | `android-game-activity` | Derives from [`AndroidAppCompat`] which is a defacto standard `Activity` base class that helps support a wider range of Android versions. Requires a build system that can compile Java or Kotlin and fetch Android dependencies from a [Maven repository][agdk_jetpack] (or link with an embedded [release][agdk_releases] of [`GameActivity`]) |
|
||||
|
||||
[`GameActivity`]: https://developer.android.com/games/agdk/game-activity
|
||||
[`GameTextInput`]: https://developer.android.com/games/agdk/add-support-for-text-input
|
||||
[`AndroidAppCompat`]: https://developer.android.com/reference/androidx/appcompat/app/AppCompatActivity
|
||||
[agdk_jetpack]: https://developer.android.com/jetpack/androidx/releases/games
|
||||
[agdk_releases]: https://developer.android.com/games/agdk/download#agdk-libraries
|
||||
[Gradle]: https://developer.android.com/studio/build
|
||||
|
||||
For example, add this to Cargo.toml:
|
||||
```toml
|
||||
winit = { version = "0.28", features = [ "android-native-activity" ] }
|
||||
|
||||
[target.'cfg(target_os = "android")'.dependencies]
|
||||
android_logger = "0.11.0"
|
||||
```
|
||||
|
||||
And, for example, define an entry point for your library like this:
|
||||
```rust
|
||||
#[cfg(target_os = "android")]
|
||||
use winit::platform::android::activity::AndroidApp;
|
||||
|
||||
#[cfg(target_os = "android")]
|
||||
#[no_mangle]
|
||||
fn android_main(app: AndroidApp) {
|
||||
use winit::platform::android::EventLoopBuilderExtAndroid;
|
||||
|
||||
android_logger::init_once(android_logger::Config::default().with_min_level(log::Level::Trace));
|
||||
|
||||
let event_loop = EventLoopBuilder::with_user_event()
|
||||
.with_android_app(app)
|
||||
.build();
|
||||
_main(event_loop);
|
||||
}
|
||||
```
|
||||
|
||||
For more details, refer to these `android-activity` [example applications](https://github.com/rib/android-activity/tree/main/examples).
|
||||
|
||||
##### Converting from `ndk-glue` to `android-activity`
|
||||
|
||||
If your application is currently based on `NativeActivity` via the `ndk-glue` crate and building with `cargo apk` then the minimal changes would be:
|
||||
1. Remove `ndk-glue` from your `Cargo.toml`
|
||||
2. Enable the `"android-native-activity"` feature for Winit: `winit = { version = "0.28", features = [ "android-native-activity" ] }`
|
||||
3. Add an `android_main` entrypoint (as above), instead of using the '`[ndk_glue::main]` proc macro from `ndk-macros` (optionally add a dependency on `android_logger` and initialize logging as above).
|

4. Pass a clone of the `AndroidApp` that your application receives to Winit when building your event loop (as shown above).
|
||||
|
||||
#### MacOS
|
||||
|
||||
A lot of functionality expects the application to be ready before you start
|
||||
doing anything; this includes creating windows, fetching monitors, drawing,
|
||||
and so on, see issues [#2238], [#2051] and [#2087].
|
||||
|
||||
If you encounter problems, you should try doing your initialization inside
|
||||
`Event::NewEvents(StartCause::Init)`.
|
||||
|
||||
#### iOS
|
||||
|
||||
Similar to macOS, iOS's main `UIApplicationMain` does some init work that's required
|
||||
by all UI related code, see issue [#1705]. You should consider creating your windows
|
||||
inside `Event::NewEvents(StartCause::Init)`.
|
||||

||||

||||

[#2051]: https://github.com/rust-windowing/winit/issues/2051
|
||||
[#2087]: https://github.com/rust-windowing/winit/issues/2087
|
||||
[#1705]: https://github.com/rust-windowing/winit/issues/1705
|
||||
|
||||
#### Redox OS
|
||||
|
||||
Redox OS has some functionality not present yet, that will be implemented when
|
||||
its orbital display server provides it.
|
||||
- Put a `<canvas id="my_id"></canvas>` element somewhere. A canvas corresponds to a winit "window".
|
||||
- Write a Javascript code that creates a global variable named `Module`. Set `Module.canvas` to
|
||||
the element of the `<canvas>` element (in the example you would retrieve it via `document.getElementById("my_id")`).
|
||||
More information [here](https://kripken.github.io/emscripten-site/docs/api_reference/module.html).
|
||||
- Make sure that you insert the `.js` file generated by Rust after the `Module` variable is created.

When using so called 'natural scrolling' (scrolling that acts like on a touch screen), this is what to expect:
|
||||
|
||||
Moving your finger downwards on a scroll wheel should make the window move down, and you should see a positive Y scroll value.
|
||||
|
||||
When moving fingers on a trackpad down and to the right, you should see positive X and Y deltas, and the window should move down and to the right.
|
||||
|
||||
With reverse scrolling, you should see the inverse behavior.
|
||||
|
||||
In both cases the example window should move like the content of a scroll area in any other application.
|
||||
|
||||
In other words, the deltas indicate the direction in which to move the content (in this case the window)."

|

This example draws a circle in the middle of a 4/1 aspect ratio canvas which acts as a useful demonstration of winit's resize handling on web.
|
||||
Even when the browser window is resized or aspect-ratio of the canvas changed the circle should always:
|
||||
* Fill the entire width or height of the canvas (whichever is smaller) without exceeding it.
|
||||
* Be perfectly round
|
||||
* Not be blurry or pixelated (there is no antialiasing so you may still see jagged edges depending on the DPI of your monitor)
|
||||
|
||||
Currently winit does not handle resizes on web so the circle is rendered incorrectly.
|
||||
This example demonstrates the desired future functionality which will possibly be provided by https://github.com/rust-windowing/winit/pull/2074

//! UI scaling is important, so read the docs for this module if you don't want to be confused.
|
||||
//!
|
||||
//! ## Why should I care about UI scaling?
|
||||
//!
|
||||
//! Modern computer screens don't have a consistent relationship between resolution and size.
|
||||
//! 1920x1080 is a common resolution for both desktop and mobile screens, despite mobile screens
|
||||
//! normally being less than a quarter the size of their desktop counterparts. What's more, neither
|
||||
//! desktop nor mobile screens are consistent resolutions within their own size classes - common
|
||||
//! mobile screens range from below 720p to above 1440p, and desktop screens range from 720p to 5K
|
||||
//! and beyond.
|
||||
//!
|
||||
//! Given that, it's a mistake to assume that 2D content will only be displayed on screens with
|
||||
//! a consistent pixel density. If you were to render a 96-pixel-square image on a 1080p screen,
|
||||
//! then render the same image on a similarly-sized 4K screen, the 4K rendition would only take up
|
||||
//! about a quarter of the physical space as it did on the 1080p screen. That issue is especially
|
||||
//! problematic with text rendering, where quarter-sized text becomes a significant legibility
|
||||
//! problem.
|
||||
//!
|
||||
//! Failure to account for the scale factor can create a significantly degraded user experience.
|
||||
//! Most notably, it can make users feel like they have bad eyesight, which will potentially cause
|
||||
//! them to think about growing elderly, resulting in them having an existential crisis. Once users
|
||||
//! enter that state, they will no longer be focused on your application.
|
||||
//!
|
||||
//! ## How should I handle it?
|
||||
//!
|
||||
//! The solution to this problem is to account for the device's *scale factor*. The scale factor is
|
||||
//! the factor UI elements should be scaled by to be consistent with the rest of the user's system -
|
||||
//! for example, a button that's normally 50 pixels across would be 100 pixels across on a device
|
||||
//! with a scale factor of `2.0`, or 75 pixels across with a scale factor of `1.5`.
|
||||
//!
|
||||
//! Many UI systems, such as CSS, expose DPI-dependent units like [points] or [picas]. That's
|
||||
//! usually a mistake, since there's no consistent mapping between the scale factor and the screen's
|
||||
//! actual DPI. Unless you're printing to a physical medium, you should work in scaled pixels rather
|
||||
//! than any DPI-dependent units.
|
||||
//!
|
||||
//! ### Position and Size types
|
||||
//!
|
||||
//! Winit's [`PhysicalPosition`] / [`PhysicalSize`] types correspond with the actual pixels on the
|
||||
//! device, and the [`LogicalPosition`] / [`LogicalSize`] types correspond to the physical pixels
|
||||
//! divided by the scale factor.
|
||||
//! All of Winit's functions return physical types, but can take either logical or physical
|
||||
//! coordinates as input, allowing you to use the most convenient coordinate system for your
|
||||
//! particular application.
|
||||
//!
|
||||
//! Winit's position and size types types are generic over their exact pixel type, `P`, to allow the
|
||||
//! API to have integer precision where appropriate (e.g. most window manipulation functions) and
|
||||
//! floating precision when necessary (e.g. logical sizes for fractional scale factors and touch
|
||||
//! input). If `P` is a floating-point type, please do not cast the values with `as {int}`. Doing so
|
||||
//! will truncate the fractional part of the float, rather than properly round to the nearest
|
||||
//! integer. Use the provided `cast` function or [`From`]/[`Into`] conversions, which handle the
|
||||
//! rounding properly. Note that precision loss will still occur when rounding from a float to an
|
||||
//! int, although rounding lessens the problem.
|
||||
//!
|
||||
//! ### Events
|
||||
//!
|
||||
//! Winit will dispatch a [`ScaleFactorChanged`] event whenever a window's scale factor has changed.
|
||||
//! This can happen if the user drags their window from a standard-resolution monitor to a high-DPI
|
||||
//! monitor, or if the user changes their DPI settings. This gives you a chance to rescale your
|
||||
//! application's UI elements and adjust how the platform changes the window's size to reflect the new
|
||||
//! scale factor. If a window hasn't received a [`ScaleFactorChanged`] event, then its scale factor
|
||||
//! can be found by calling [`window.scale_factor()`].
|
||||
//!
|
||||
//! ## How is the scale factor calculated?
|
||||
//!
|
||||
//! Scale factor is calculated differently on different platforms:
|
||||
//!
|
||||
//! - **Windows:** On Windows 8 and 10, per-monitor scaling is readily configured by users from the
|
||||
//! display settings. While users are free to select any option they want, they're only given a
|
||||
//! selection of "nice" scale factors, i.e. 1.0, 1.25, 1.5... on Windows 7, the scale factor is
|
||||
//! global and changing it requires logging out. See [this article][windows_1] for technical
|
||||
//! details.
|
||||
//! - **macOS:** Recent versions of macOS allow the user to change the scaling factor for certain
|
||||
//! displays. When this is available, the user may pick a per-monitor scaling factor from a set
|
||||
//! of pre-defined settings. All "retina displays" have a scaling factor above 1.0 by default but
|
||||
//! the specific value varies across devices.
|
||||
//! - **X11:** Many man-hours have been spent trying to figure out how to handle DPI in X11. Winit
|
||||
//! currently uses a three-pronged approach:
|
||||
//! + Use the value in the `WINIT_X11_SCALE_FACTOR` environment variable, if present.
|
||||
//! + If not present, use the value set in `Xft.dpi` in Xresources.
|
||||
//! + Otherwise, calculate the scale factor based on the millimeter monitor dimensions provided by XRandR.
|
||||
//!
|
||||
//! If `WINIT_X11_SCALE_FACTOR` is set to `randr`, it'll ignore the `Xft.dpi` field and use the
|
||||
//! XRandR scaling method. Generally speaking, you should try to configure the standard system
|
||||
//! variables to do what you want before resorting to `WINIT_X11_SCALE_FACTOR`.
|
||||
//! - **Wayland:** On Wayland, scale factors are set per-screen by the server, and are always
|
||||
//! integers (most often 1 or 2).
|
||||
//! - **iOS:** Scale factors are set by Apple to the value that best suits the device, and range
|
||||
//! from `1.0` to `3.0`. See [this article][apple_1] and [this article][apple_2] for more
|
||||
//! information.
|
||||
//! - **Android:** Scale factors are set by the manufacturer to the value that best suits the
|
||||
//! device, and range from `1.0` to `4.0`. See [this article][android_1] for more information.
|
||||
//! - **Web:** The scale factor is the ratio between CSS pixels and the physical device pixels.
|
||||
//! In other words, it is the value of [`window.devicePixelRatio`][web_1]. It is affected by
|
||||
//! both the screen scaling and the browser zoom level and can go below `1.0`.

//! DPI is important, so read the docs for this module if you don't want to be confused.
|
||||
//!
|
||||
//! Originally, `winit` dealt entirely in physical pixels (excluding unintentional inconsistencies), but now all
|
||||
//! window-related functions both produce and consume logical pixels. Monitor-related functions still use physical
|
||||
//! pixels, as do any context-related functions in `glutin`.
|
||||
//!
|
||||
//! If you've never heard of these terms before, then you're not alone, and this documentation will explain the
|
||||
//! concepts.
|
||||
//!
|
||||
//! Modern screens have a defined physical resolution, most commonly 1920x1080. Indepedent of that is the amount of
|
||||
//! space the screen occupies, which is to say, the height and width in millimeters. The relationship between these two
|
||||
//! measurements is the *pixel density*. Mobile screens require a high pixel density, as they're held close to the
|
||||
//! eyes. Larger displays also require a higher pixel density, hence the growing presence of 1440p and 4K displays.
|
||||
//!
|
||||
//! So, this presents a problem. Let's say we want to render a square 100px button. It will occupy 100x100 of the
|
||||
//! screen's pixels, which in many cases, seems perfectly fine. However, because this size doesn't account for the
|
||||
//! screen's dimensions or pixel density, the button's size can vary quite a bit. On a 4K display, it would be unusably
|
||||
//! small.
|
||||
//!
|
||||
//! That's a description of what happens when the button is 100x100 *physical* pixels. Instead, let's try using 100x100
|
||||
//! *logical* pixels. To map logical pixels to physical pixels, we simply multiply by the DPI (dots per inch) factor.
|
||||
//! On a "typical" desktop display, the DPI factor will be 1.0, so 100x100 logical pixels equates to 100x100 physical
|
||||
//! pixels. However, a 1440p display may have a DPI factor of 1.25, so the button is rendered as 125x125 physical pixels.
|
||||
//! Ideally, the button now has approximately the same perceived size across varying displays.
|
||||
//!
|
||||
//! Failure to account for the DPI factor can create a badly degraded user experience. Most notably, it can make users
|
||||
//! feel like they have bad eyesight, which will potentially cause them to think about growing elderly, resulting in
|
||||
//! them entering an existential panic. Once users enter that state, they will no longer be focused on your application.
|
||||
//!
|
||||
//! There are two ways to get the DPI factor:
|
||||
//! - You can track the [`HiDpiFactorChanged`](../enum.WindowEvent.html#variant.HiDpiFactorChanged) event of your
|
||||
//! windows. This event is sent any time the DPI factor changes, either because the window moved to another monitor,
|
||||
//! or because the user changed the configuration of their screen.
|
||||
//! - You can also retrieve the DPI factor of a monitor by calling
|
||||
//! [`MonitorId::get_hidpi_factor`](../struct.MonitorId.html#method.get_hidpi_factor), or the
|
||||
//! current DPI factor applied to a window by calling
|
||||
//! [`Window::get_hidpi_factor`](../struct.Window.html#method.get_hidpi_factor), which is roughly equivalent
|
||||
//! to `window.get_current_monitor().get_hidpi_factor()`.
|
||||
//!
|
||||
//! Depending on the platform, the window's actual DPI factor may only be known after
|
||||
//! the event loop has started and your window has been drawn once. To properly handle these cases,
|
||||
//! the most robust way is to monitor the [`HiDpiFactorChanged`](../enum.WindowEvent.html#variant.HiDpiFactorChanged)
|
||||
//! event and dynamically adapt your drawing logic to follow the DPI factor.
|
||||
//!
|
||||
//! Here's an overview of what sort of DPI factors you can expect, and where they come from:
|
||||
//! - **Windows:** On Windows 8 and 10, per-monitor scaling is readily configured by users from the display settings.
|
||||
//! While users are free to select any option they want, they're only given a selection of "nice" DPI factors, i.e.
|
||||
//! 1.0, 1.25, 1.5... on Windows 7, the DPI factor is global and changing it requires logging out.
|
||||
//! - **macOS:** The buzzword is "retina displays", which have a DPI factor of 2.0. Otherwise, the DPI factor is 1.0.
|
||||
//! Intermediate DPI factors are never used, thus 1440p displays/etc. aren't properly supported. It's possible for any
|
||||
//! display to use that 2.0 DPI factor, given the use of the command line.
|
||||
//! - **X11:** On X11, we calcuate the DPI factor based on the millimeter dimensions provided by XRandR. This can
|
||||
//! result in a wide range of possible values, including some interesting ones like 1.0833333333333333. This can be
|
||||
//! overridden using the `WINIT_HIDPI_FACTOR` environment variable, though that's not recommended.
|
||||
//! - **Wayland:** On Wayland, DPI factors are set per-screen by the server, and are always integers (most often 1 or 2).
|
||||
//! - **iOS:** DPI factors are both constant and device-specific on iOS.
|
||||
//! - **Android:** This feature isn't yet implemented on Android, so the DPI factor will always be returned as 1.0.
|
||||
//!
|
||||
//! The window's logical size is conserved across DPI changes, resulting in the physical size changing instead. This
|
||||
//! may be surprising on X11, but is quite standard elsewhere. Physical size changes always produce a
|
||||
//! [`Resized`](../enum.WindowEvent.html#variant.Resized) event, even on platforms where no resize actually occurs,
|
||||
//! such as macOS and Wayland. As a result, it's not necessary to separately handle
|
||||
//! [`HiDpiFactorChanged`](../enum.WindowEvent.html#variant.HiDpiFactorChanged) if you're only listening for size.
|
||||
//!
|
||||
//! Your GPU has no awareness of the concept of logical pixels, and unless you like wasting pixel density, your
|
||||
//! framebuffer's size should be in physical pixels.
|
||||
//!
|
||||
//! `winit` will send [`Resized`](../enum.WindowEvent.html#variant.Resized) events whenever a window's logical size
|
||||
//! changes, and [`HiDpiFactorChanged`](../enum.WindowEvent.html#variant.HiDpiFactorChanged) events
|
||||
//! whenever the DPI factor changes. Receiving either of these events means that the physical size of your window has
|
||||
//! changed, and you should recompute it using the latest values you received for each. If the logical size and the
|
||||
//! DPI factor change simultaneously, `winit` will send both events together; thus, it's recommended to buffer
|
||||
//! these events and process them at the end of the queue.
|
||||
//!
|
||||
//! If you never received any [`HiDpiFactorChanged`](../enum.WindowEvent.html#variant.HiDpiFactorChanged) events,
|
||||
//! then your window's DPI factor is 1.

//! Winit is a cross-platform window creation and event loop management library.

|

//! # Building windows
|
||||
//! # Building a window
|
||||
//!
|
||||
//! Before you can build a [`Window`], you first need to build an [`EventLoop`]. This is done with the
|
||||
//! [`EventLoop::new()`] function.
|
||||
//! Before you can build a window, you first need to build an `EventsLoop`. This is done with the
|
||||
//! `EventsLoop::new()` function. Example:
|
||||
//!
|
||||
//! ```no_run
|
||||
//! use winit::event_loop::EventLoop;
|
||||
//! let event_loop = EventLoop::new();
|
||||
//! use winit::EventsLoop;
|
||||
//! let events_loop = EventsLoop::new();
|
||||
//! ```
|
||||
//!
|
||||
//! Once this is done there are two ways to create a [`Window`]:
|
||||
//! Once this is done there are two ways to create a window:
|
||||
//!
|
||||
//! - Calling [`Window::new(&event_loop)`][window_new].
|
||||
//! - Calling [`let builder = WindowBuilder::new()`][window_builder_new] then [`builder.build(&event_loop)`][window_builder_build].
|
||||
//! - Calling `Window::new(&events_loop)`.
|
||||
//! - Calling `let builder = WindowBuilder::new()` then `builder.build(&events_loop)`.
|
||||
//!
|
||||
//! The first method is the simplest, and will give you default values for everything. The second
|
||||
//! method allows you to customize the way your [`Window`] will look and behave by modifying the
|
||||
//! fields of the [`WindowBuilder`] object before you create the [`Window`].
|
||||
//! The first way is the simplest way and will give you default values for everything.
|
||||
//!
|
||||
//! # Event handling
|
||||
//! The second way allows you to customize the way your window will look and behave by modifying
|
||||
//! the fields of the `WindowBuilder` object before you create the window.
|
||||
//!
|
||||
//! Once a [`Window`] has been created, it will generate different *events*. A [`Window`] object can
|
||||
//! generate [`WindowEvent`]s when certain input events occur, such as a cursor moving over the
|
||||
//! window or a key getting pressed while the window is focused. Devices can generate
|
||||
//! [`DeviceEvent`]s, which contain unfiltered event data that isn't specific to a certain window.
|
||||
//! Some user activity, like mouse movement, can generate both a [`WindowEvent`] *and* a
|
||||
//! [`DeviceEvent`]. You can also create and handle your own custom [`UserEvent`]s, if desired.
|
||||
//! # Events handling
|
||||
//!
|
||||
//! You can retrieve events by calling [`EventLoop::run`][event_loop_run]. This function will
|
||||
//! dispatch events for every [`Window`] that was created with that particular [`EventLoop`], and
|
||||
//! will run until the `control_flow` argument given to the closure is set to
|
||||
//! [`ControlFlow`]`::`[`ExitWithCode`] (which [`ControlFlow`]`::`[`Exit`] aliases to), at which
|
||||
//! point [`Event`]`::`[`LoopDestroyed`] is emitted and the entire program terminates.
|
||||
//! Once a window has been created, it will *generate events*. For example whenever the user moves
|
||||
//! the window, resizes the window, moves the mouse, etc. an event is generated.
|
||||
//!
|
||||
//! Winit no longer uses a `EventLoop::poll_events() -> impl Iterator<Event>`-based event loop
|
||||
//! model, since that can't be implemented properly on some platforms (e.g web, iOS) and works poorly on
|
||||
//! most other platforms. However, this model can be re-implemented to an extent with
|
||||
//! [`EventLoopExtRunReturn::run_return`]. See that method's documentation for more reasons about why
|
||||
//! it's discouraged, beyond compatibility reasons.
|
||||
//! The events generated by a window can be retrieved from the `EventsLoop` the window was created
|
||||
//! with.
|
||||
//!
|
||||
//! There are two ways to do so. The first is to call `events_loop.poll_events(...)`, which will
|
||||
//! retrieve all the events pending on the windows and immediately return after no new event is
|
||||
//! available. You usually want to use this method in application that render continuously on the
|
||||
//! screen, such as video games.
|
||||
//!
|
||||
//! ```no_run
|
||||
//! use winit::{
|
||||
//! event::{Event, WindowEvent},
|
||||
//! event_loop::EventLoop,
|
||||
//! window::WindowBuilder,
|
||||
//! };
|
||||
//! use winit::{Event, WindowEvent};
|
||||
//! use winit::dpi::LogicalSize;
|
||||
//! # use winit::EventsLoop;
|
||||
//! # let mut events_loop = EventsLoop::new();
|
||||
//!
|
||||
//! let event_loop = EventLoop::new();
|
||||
//! let window = WindowBuilder::new().build(&event_loop).unwrap();
|
||||
//! loop {
|
||||
//! events_loop.poll_events(|event| {
|
||||
//! match event {
|
||||
//! Event::WindowEvent {
|
||||
//! event: WindowEvent::Resized(LogicalSize { width, height }),
|
||||
//! ..
|
||||
//! } => {
|
||||
//! println!("The window was resized to {}x{}", width, height);
|
||||
//! },
|

//! _ => ()

|

//! });
|

//! }
|

|
||||
//!
|
||||
//! event_loop.run(move |event, _, control_flow| {
|
||||
//! // ControlFlow::Poll continuously runs the event loop, even if the OS hasn't
|
||||
//! // dispatched any events. This is ideal for games and similar applications.
|
||||
//! control_flow.set_poll();
|
||||
//! The second way is to call `events_loop.run_forever(...)`. As its name tells, it will run
|
||||
//! forever unless it is stopped by returning `ControlFlow::Break`.
|
||||
//!
|
||||
//! // ControlFlow::Wait pauses the event loop if no events are available to process.
|
||||
//! // This is ideal for non-game applications that only update in response to user
|
||||
//! // input, and uses significantly less power/CPU time than ControlFlow::Poll.
|
||||
//! control_flow.set_wait();
|
||||
//! ```no_run
|
||||
//! use winit::{ControlFlow, Event, WindowEvent};
|

//! // applications which do not always need to. Applications that redraw continuously
|

|
||||
//! Event::RedrawRequested(_) => {
|
||||
//! // Redraw the application.
|
||||
//! //
|
||||
//! // It's preferable for applications that do not render continuously to render in
|
||||
//! // this event rather than in MainEventsCleared, since rendering in here allows
|

|

|

//!
|
||||
//! [`Event`]`::`[`WindowEvent`] has a [`WindowId`] member. In multi-window environments, it should be
|
||||
//! compared to the value returned by [`Window::id()`][window_id_fn] to determine which [`Window`]
|
||||
//! dispatched the event.
|
||||
//! If you use multiple windows, the `WindowEvent` event has a member named `window_id`. You can
|
||||
//! compare it with the value returned by the `id()` method of `Window` in order to know which
|
||||
//! window has received the event.
|
||||
//!
|
||||
//! # Drawing on the window
|
||||
//!
|
||||
//! Winit doesn't directly provide any methods for drawing on a [`Window`]. However it allows you to
|
||||
//! retrieve the raw handle of the window and display (see the [`platform`] module and/or the
|
||||
//! [`raw_window_handle`] and [`raw_display_handle`] methods), which in turn allows
|
||||
//! you to create an OpenGL/Vulkan/DirectX/Metal/etc. context that can be used to render graphics.
|
||||
//! Winit doesn't provide any function that allows drawing on a window. However it allows you to
|
||||
//! retrieve the raw handle of the window (see the `os` module for that), which in turn allows you
|
||||
//! to create an OpenGL/Vulkan/DirectX/Metal/etc. context that will draw on the window.
|
||||
//!
|
||||
//! Note that many platforms will display garbage data in the window's client area if the
|
||||
//! application doesn't render anything to the window by the time the desktop compositor is ready to
|
||||
//! display the window to the user. If you notice this happening, you should create the window with
|
||||
//! [`visible` set to `false`](crate::window::WindowBuilder::with_visible) and explicitly make the
|
||||
//! window visible only once you're ready to render into it.

//! iOS support
|
||||
//!
|
||||
//! # Building app
|
||||
//! To build ios app you will need rustc built for this targets:
|
||||
//!
|
||||
//! - armv7-apple-ios
|
||||
//! - armv7s-apple-ios
|
||||
//! - i386-apple-ios
|
||||
//! - aarch64-apple-ios
|
||||
//! - x86_64-apple-ios
|
||||
//!
|
||||
//! Then
|
||||
//!
|
||||
//! ```
|
||||
//! cargo build --target=...
|
||||
//! ```
|
||||
//! The simplest way to integrate your app into xcode environment is to build it
|
||||
//! as a static library. Wrap your main function and export it.
|
||||
//!
|
||||
//! ```rust, ignore
|
||||
//! #[no_mangle]
|
||||
//! pub extern fn start_winit_app() {
|
||||
//! start_inner()
|
||||
//! }
|
||||
//!
|
||||
//! fn start_inner() {
|
||||
//! ...
|
||||
//! }
|
||||
//!
|
||||
//! ```
|
||||
//!
|
||||
//! Compile project and then drag resulting .a into Xcode project. Add winit.h to xcode.
|
||||
//!
|
||||
//! ```ignore
|
||||
//! void start_winit_app();
|
||||
//! ```
|
||||
//!
|
||||
//! Use start_winit_app inside your xcode's main function.
|
||||
//!
|
||||
//!
|
||||
//! # App lifecycle and events
|
||||
//!
|
||||
//! iOS environment is very different from other platforms and you must be very
|
||||
//! careful with it's events. Familiarize yourself with
|
||||
//! [app lifecycle](https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIApplicationDelegate_Protocol/).
|
||||
//!
|
||||
//!
|
||||
//! This is how those event are represented in winit:
|
||||
//!
|
||||
//! - applicationDidBecomeActive is Focused(true)
|
||||
//! - applicationWillResignActive is Focused(false)
|
||||
//! - applicationDidEnterBackground is Suspended(true)
|
||||
//! - applicationWillEnterForeground is Suspended(false)
|
||||
//! - applicationWillTerminate is Destroyed
|
||||
//!
|
||||
//! Keep in mind that after Destroyed event is received every attempt to draw with
|
||||
//! opengl will result in segfault.
|
||||
//!
|
||||
//! Also note that app will not receive Destroyed event if suspended, it will be SIGKILL'ed
