## 0.30.6
### Added

to fully disable the menu bar and dock in Borderless Fullscreen as commonly done in games.
- On X11, the `window` example now understands the `X11_VISUAL_ID` and `X11_SCREEN_ID` env
variables to test the respective modifiers of window creation.
- On Android, the soft keyboard can now be shown using `Window::set_ime_allowed`.

- On macOS, fix panic when releasing not available monitor.
- On MacOS, return the system theme in `Window::theme()` if no theme override is set.
## 0.30.4
### Changed

### Fixed
- On Wayland, avoid crashing when compositor is misbehaving.
- On Web, fix `WindowEvent::Resized` not using `requestAnimationFrame` when sending
`WindowEvent::RedrawRequested` and also potentially causing `WindowEvent::RedrawRequested`
to not be de-duplicated.
- Account for different browser engine implementations of pointer movement coordinate space.
## 0.30.3
### Added
- On Web, add `EventLoopExtWebSys::(set_)poll_strategy()` to allow setting
control flow strategies before starting the event loop.
- On Web, add `WaitUntilStrategy`, which allows to set different strategies for
`ControlFlow::WaitUntil`. By default the Prioritized Task Scheduling API is
used, with a fallback to `setTimeout()` with a trick to circumvent throttling
to 4ms. But an option to use a Web worker to schedule the timer is available
as well, which commonly prevents any throttling when the window is not focused.
### Changed
- On macOS, set the window theme on the `NSWindow` instead of application-wide.
### Fixed
- On X11, build on arm platforms.
- On macOS, fixed `WindowBuilder::with_theme` not having any effect on the window.
## 0.30.2

- On macOS, fix the range in `Ime::Preedit`.
- On macOS, use the system's internal mechanisms for queuing events.
- On macOS, handle events directly instead of queuing when possible.

- Add `OwnedDisplayHandle` type for allowing safe display handle usage outside of
trivial cases.

- Add `WindowBuilder::with_cursor` and `Window::set_cursor` which takes a
`CursorIcon` or `CustomCursor`.
- Add `Sync` implementation for `EventLoopProxy<T: Send>`.
- Add `Window::default_attributes` to get default `WindowAttributes`.
- Add `EventLoop::builder` to get `EventLoopBuilder` without export.
- Add `CustomCursor::from_rgba` to allow creating cursor images from RGBA data.

- On Windows, add `AnyThread` API to access window handle off the main thread.
### Changed
- Bump MSRV from `1.65` to `1.70`.
- On Wayland, bump `sctk-adwaita` to `0.9.0`, which changed system library
crates. This change is a **cascading breaking change**, you must do breaking
change as well, even if you don't expose winit.
- Rename `TouchpadMagnify` to `PinchGesture`.
- Rename `SmartMagnify` to `DoubleTapGesture`.
- Rename `TouchpadRotate` to `RotationGesture`.
- Rename `EventLoopWindowTarget` to `ActiveEventLoop`.
- Rename `platform::x11::XWindowType` to `platform::x11::WindowType`.
- Rename `VideoMode` to `VideoModeHandle` to represent that it doesn't hold
static data.
- Make `Debug` formatting of `WindowId` more concise.
- Move `dpi` types to its own crate, and re-export it from the root crate.
- Replace `log` with `tracing`, use `log` feature on `tracing` to restore old
behavior.
- `EventLoop::with_user_event` now returns `EventLoopBuilder`.
- On Web, return `HandleError::Unavailable` when a window handle is not available.
- On Web, return `RawWindowHandle::WebCanvas` instead of `RawWindowHandle::Web`.
- On Web, remove queuing fullscreen request in absence of transient activation.

- On macOS, return `HandleError::Unavailable` when a window handle is not available.
- On Windows, remove `WS_CAPTION`, `WS_BORDER`, and `WS_EX_WINDOWEDGE` styles
for child windows without decorations.
- On Android, bump `ndk` to `0.9.0` and `android-activity` to `0.6.0`,
and remove unused direct dependency on `ndk-sys`.
### Deprecated
- Deprecate `EventLoop::run`, use `EventLoop::run_app`.
- Deprecate `EventLoopExtRunOnDemand::run_on_demand`, use `EventLoop::run_app_on_demand`.
- Deprecate `EventLoopExtPumpEvents::pump_events`, use `EventLoopExtPumpEvents::pump_app_events`.
The new `app` APIs accept a newly added `ApplicationHandler<T>` instead of
`Fn`. The semantics are mostly the same, given that the capture list of the
closure is your new `State`. Consider the following code:
```rust,no_run
use winit::event::Event;
use winit::event_loop::EventLoop;
use winit::window::Window;
struct MyUserEvent;
let event_loop = EventLoop::<MyUserEvent>::with_user_event().build().unwrap();
let window = event_loop.create_window(Window::default_attributes()).unwrap();
let mut counter = 0;
let _ = event_loop.run(move |event, event_loop| {
match event {
Event::AboutToWait => {
window.request_redraw();
counter += 1;
}
Event::WindowEvent { window_id, event } => {
// Handle window event.
}
Event::UserEvent(event) => {
// Handle user event.
}
Event::DeviceEvent { device_id, event } => {
// Handle device event.
}
_ => (),
}
});
```
To migrate this code, you should move all the captured values into some
newtype `State` and implement `ApplicationHandler` for this type. Finally,
we move particular `match event` arms into methods on `ApplicationHandler`,
for example:
```rust,no_run
use winit::application::ApplicationHandler;
use winit::event::{Event, WindowEvent, DeviceEvent, DeviceId};
use winit::event_loop::{EventLoop, ActiveEventLoop};
use winit::window::{Window, WindowId};
struct MyUserEvent;
struct State {
window: Window,
counter: i32,
}
impl ApplicationHandler<MyUserEvent> for State {
fn user_event(&mut self, event_loop: &ActiveEventLoop, user_event: MyUserEvent) {
// Handle user event.
}
fn resumed(&mut self, event_loop: &ActiveEventLoop) {
// Your application got resumed.
}
fn window_event(&mut self, event_loop: &ActiveEventLoop, window_id: WindowId, event: WindowEvent) {
// Handle window event.
}
fn device_event(&mut self, event_loop: &ActiveEventLoop, device_id: DeviceId, event: DeviceEvent) {
// Handle device event.
}
fn about_to_wait(&mut self, event_loop: &ActiveEventLoop) {
self.window.request_redraw();
self.counter += 1;
}
}
let event_loop = EventLoop::<MyUserEvent>::with_user_event().build().unwrap();
#[allow(deprecated)]
let window = event_loop.create_window(Window::default_attributes()).unwrap();
let mut state = State { window, counter: 0 };
let _ = event_loop.run_app(&mut state);
```
Please submit your feedback after migrating in [this issue](https://github.com/rust-windowing/winit/issues/3626).
- Deprecate `Window::set_cursor_icon`, use `Window::set_cursor`.
### Removed
- Remove `Window::new`, use `ActiveEventLoop::create_window` instead.
You now have to create your windows inside the actively running event loop
(usually the `new_events(cause: StartCause::Init)` or `resumed()` events),
and can no longer do it before the application has properly launched.
This change is done to fix many long-standing issues on iOS and macOS, and
will improve things on Wayland once fully implemented.
To ease migration, we provide the deprecated `EventLoop::create_window` that
will allow you to bypass this restriction in this release.
Using the migration example from above, you can change your code as follows:
```rust,no_run
use winit::application::ApplicationHandler;
use winit::event::{Event, WindowEvent, DeviceEvent, DeviceId};
use winit::event_loop::{EventLoop, ActiveEventLoop};
use winit::window::{Window, WindowId};
#[derive(Default)]
struct State {
// Use an `Option` to allow the window to not be available until the
// application is properly running.
window: Option<Window>,
counter: i32,
}
impl ApplicationHandler for State {
// This is a common indicator that you can create a window.
fn resumed(&mut self, event_loop: &ActiveEventLoop) {
self.window = Some(event_loop.create_window(Window::default_attributes()).unwrap());
}
fn window_event(&mut self, event_loop: &ActiveEventLoop, window_id: WindowId, event: WindowEvent) {
// `unwrap` is fine, the window will always be available when
// receiving a window event.
let window = self.window.as_ref().unwrap();
// Handle window event.
}
fn device_event(&mut self, event_loop: &ActiveEventLoop, device_id: DeviceId, event: DeviceEvent) {
// Handle window event.
}
fn about_to_wait(&mut self, event_loop: &ActiveEventLoop) {
if let Some(window) = self.window.as_ref() {
window.request_redraw();
self.counter += 1;
}
}
}
let event_loop = EventLoop::new().unwrap();
let mut state = State::default();
let _ = event_loop.run_app(&mut state);
```
