Struct App

pub struct App { /* private fields */ }

A handle to a Cushy application.

Implementations

impl App

pub fn monitors(&self) -> Option<Monitors>

Returns a snapshot of information about the monitors connected to this device.

Returns None if the app is not currently running.

pub fn prevent_shutdown(&self) -> Option<ShutdownGuard>

Creates a guard that prevents this app from shutting down.

If the app is not currently running, this function returns None.

Once a guard is allocated the app will not be closed automatically when the final window is closed. If the final shutdown guard is dropped while no windows are open, the app will be closed.

pub fn execute<Callback>(&self, callback: Callback) -> bool

where Callback: FnOnce(&ExecutingApp<'_, WindowCommand>) + Send + 'static,

Executes callback on the main event loop thread.

Returns true if the callback was able to be sent to be executed. The app may still terminate before the callback is executed regardless of the result of this function. The only way to know with certainty that callback is executed is to have callback notify the caller of its completion.
