Required Associated Types

type Runtime: Runtime<T, Handle = Self>

Required Methods

fn create_proxy(&self) -> <Self::Runtime as Runtime<T>>::EventLoopProxy

Creates an EventLoopProxy that can be used to dispatch user events to the main event loop.

fn request_exit(&self, code: i32) -> Result<()>

Requests an exit of the event loop.

fn create_window<F: Fn(RawWindow<'_>) + Send + 'static>( &self, pending: PendingWindow<T, Self::Runtime>, after_window_creation: Option<F>, ) -> Result<DetachedWindow<T, Self::Runtime>>

Create a new window.

fn create_webview( &self, window_id: WindowId, pending: PendingWebview<T, Self::Runtime>, ) -> Result<DetachedWebview<T, Self::Runtime>>

Create a new webview.

fn run_on_main_thread<F: FnOnce() + Send + 'static>(&self, f: F) -> Result<()>

Run a task on the main thread.

fn display_handle(&self) -> Result<DisplayHandle<'_>, HandleError>

Get a handle to the display controller of the windowing system.

fn primary_monitor(&self) -> Option<Monitor>

Returns the primary monitor of the system.

Returns None if it can’t identify any monitor as a primary one.

fn monitor_from_point(&self, x: f64, y: f64) -> Option<Monitor>

Returns the monitor that contains the given point.

fn available_monitors(&self) -> Vec<Monitor>

Returns the list of all the monitors available on the system.

fn cursor_position(&self) -> Result<PhysicalPosition<f64>>

Get the cursor position relative to the top-left hand corner of the desktop.

fn set_theme(&self, theme: Option<Theme>)

Sets the app theme.

fn fetch_data_store_identifiers<F: FnOnce(Vec<[u8; 16]>) + Send + 'static>( &self, cb: F, ) -> Result<()>

Available on macOS or iOS only.

fn remove_data_store<F: FnOnce(Result<()>) + Send + 'static>( &self, uuid: [u8; 16], cb: F, ) -> Result<()>

Available on macOS or iOS only.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
