Window dispatcher. A thread-safe handle to the window APIs.

Required Associated Types

type Runtime: Runtime<T>

The runtime this WindowDispatch runs under.

type WindowBuilder: WindowBuilder

The window builder type.

Required Methods

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

Run a task on the main thread.

fn on_window_event<F: Fn(&WindowEvent) + Send + 'static>( &self, f: F, ) -> WindowEventId

Registers a window event handler.

fn scale_factor(&self) -> Result<f64>

Returns the scale factor that can be used to map logical pixels to physical pixels, and vice versa.

fn inner_position(&self) -> Result<PhysicalPosition<i32>>

Returns the position of the top-left hand corner of the window’s client area relative to the top-left hand corner of the desktop.

fn outer_position(&self) -> Result<PhysicalPosition<i32>>

Returns the position of the top-left hand corner of the window relative to the top-left hand corner of the desktop.

fn inner_size(&self) -> Result<PhysicalSize<u32>>

Returns the physical size of the window’s client area.

The client area is the content of the window, excluding the title bar and borders.

fn outer_size(&self) -> Result<PhysicalSize<u32>>

Returns the physical size of the entire window.

These dimensions include the title bar and borders. If you don’t want that (and you usually don’t), use inner_size instead.

fn is_fullscreen(&self) -> Result<bool>

Gets the window’s current fullscreen state.

fn is_minimized(&self) -> Result<bool>

Gets the window’s current minimized state.

fn is_maximized(&self) -> Result<bool>

Gets the window’s current maximized state.

fn is_focused(&self) -> Result<bool>

Gets the window’s current focus state.

fn is_decorated(&self) -> Result<bool>

Gets the window’s current decoration state.

fn is_resizable(&self) -> Result<bool>

Gets the window’s current resizable state.

fn is_maximizable(&self) -> Result<bool>

Gets the window’s native maximize button state.

fn is_enabled(&self) -> Result<bool>

Whether the window is enabled or disable.

fn title(&self) -> Result<String>

Gets the window’s current title.

fn current_monitor(&self) -> Result<Option<Monitor>>

Returns the monitor on which the window currently resides.

Returns None if current monitor can’t be detected.

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

Returns the primary monitor of the system.

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

Returns the current window theme.

fn center(&self) -> Result<()>

Centers the window.

fn request_user_attention( &self, request_type: Option<UserAttentionType>, ) -> Result<()>

Requests user attention to the window.

Providing None will unset the request for user attention.

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

Create a new window.

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

Create a new webview.

fn set_resizable(&self, resizable: bool) -> Result<()>

fn set_enabled(&self, enabled: bool) -> Result<()>

Enable or disable the window.

Platform-specific

• Android / iOS: Unsupported.

fn set_maximizable(&self, maximizable: bool) -> Result<()>

• Linux / iOS / Android: Unsupported.

fn set_minimizable(&self, minimizable: bool) -> Result<()>

Updates the window’s native minimize button state.

Platform-specific

• Linux / iOS / Android: Unsupported.

fn set_closable(&self, closable: bool) -> Result<()>

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.
