//! Listen for window focus events using a wry event handler
|
|
//!
|
|
//! This example shows how to use the use_wry_event_handler hook to listen for window focus events.
|
|
//! We can intercept any Wry event, but in this case we're only interested in the WindowEvent::Focused event.
|
|
//!
|
|
//! This lets you do things like backgrounding tasks, pausing animations, or changing the UI when the window is focused or not.
