Struct WindowHandle 

pub struct WindowHandle { /* private fields */ }

Sendable handle that queues commands and wakes the native UI loop.

Implementations

impl WindowHandle

pub fn set_wakeup<F>(&self, wakeup: F)

where F: Fn() + Send + Sync + 'static,

Install the backend wakeup callback.

Installing a callback while commands are queued schedules one wakeup. The callback is always invoked after releasing the queue lock.

pub fn drain_commands(&self) -> Vec<WindowCommand>

Drain queued commands on the UI thread.

pub fn send(&self, command: WindowCommand) -> Result<(), WindowCommandError>

Queue a native command.

Success means the command was accepted into the bounded queue, not that the native UI thread has already applied it.

pub fn set_title( &self, title: impl Into<String>, ) -> Result<(), WindowCommandError>

Queue title update.

pub fn set_background(&self, color: Rgba) -> Result<(), WindowCommandError>

Queue a native and document background update without changing the bundle manifest.

pub fn set_size( &self, width: u32, height: u32, ) -> Result<(), WindowCommandError>

Queue size update.

pub fn minimize(&self) -> Result<(), WindowCommandError>

Queue minimization.

pub fn maximize(&self) -> Result<(), WindowCommandError>

Queue maximization.

pub fn unmaximize(&self) -> Result<(), WindowCommandError>

Queue unmaximization.

pub fn fullscreen(&self, value: bool) -> Result<(), WindowCommandError>

Queue fullscreen change.

pub fn center(&self) -> Result<(), WindowCommandError>

Queue centering.

pub fn focus(&self) -> Result<(), WindowCommandError>

Queue focus.

pub fn request_close(&self) -> Result<(), WindowCommandError>

Queue a native close request.

pub fn start_drag(&self) -> Result<(), WindowCommandError>

Queue native drag.

pub fn set_always_on_top(&self, value: bool) -> Result<(), WindowCommandError>

Queue always-on-top change.
