Apps that build their own muda app menu can't use install_app_menu: it replaces the whole menu and sets muda's process-wide event handler. QUIT_MENU_ID and on_menu_event(ctx, id) let them give their own Quit item the id and route its event through the app's close handling. Neither needs muda, so any muda version works. install_app_menu now uses both. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

//! The macOS app menu, with a Quit that asks the app first.
|
|
//!
|
|
//! winit's default app menu sends Quit (⌘Q) straight to `-[NSApplication terminate:]`, and winit
|
|
//! does not implement `applicationShouldTerminate:`, so the app is never asked: unsaved work is
|
|
//! lost without a prompt. This menu has the same items, built with muda, but its Quit asks the
|
|
//! window to close (`ViewportCommand::Close`). That goes through the app's own close handling,
|
|
//! the same as the close button, and [`crate::on_close_request`] then quits. Apps with their own
|
|
//! muda menu use [`crate::QUIT_MENU_ID`] and [`crate::on_menu_event`] directly.
