Expand description

A Send handle to the runtime.

Required Associated Types§

Source

type Runtime: Runtime<T, Handle = Self>

Required Methods§

Source

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.

Source

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

Requests an exit of the event loop.

Source

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.

Source

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

Create a new webview.

Source

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

Run a task on the main thread.

Source

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

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

Source

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.

Source

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

Returns the monitor that contains the given point.

Source

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

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

Source

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

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

Source

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

Sets the app theme.

Source

fn set_device_event_filter(&self, filter: DeviceEventFilter)

Change the device event filter mode.

See Runtime::set_device_event_filter for details.

§Platform-specific

See Runtime::set_device_event_filter for details.

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.
