Changing menu items on runtime

[FrankLaterza]

Has anyone found a way to update menu items at runtime? I can't find a way to remove or add items to the menu from MenuHandle. Probably because there isn't a way. Does anyone know of a workaround? Could I rebuild them menu from the app handle?

I ran across this while trying to add & remove menu items in Tauri and I got it working using v2 (apparently this wasn't possible in v1 according to another github issue I saw).

Forgive the fact these functions don't take any parameters. The ones in my app are specific to a couple menus, but I thought it was useful to see the types in play here.

Here's some code I use to remove a menu item:

pub fn remove_submenu_by_id<R: tauri::Runtime>(
    app: &tauri::AppHandle<R>,
) -> Result<(), tauri::Error> {
    let Some(root) = app.menu() else {
        return Ok(());
    };

    // This removes a menu item from the macOS "app menu" (the leftmost one)
    if let Some(app_menu) = find(&root, "MyAppName") {
        if let Some(submenu) = app_menu.get("the_submenu_id") {
            app_menu.remove(&submenu)?;
        }
    }

    Ok(())
}

And some code for adding a menu:

pub fn add_submenu_somewhere<R: tauri::Runtime>(
    app: &tauri::AppHandle<R>,
) -> Result<(), tauri::Error> {
    let Some(root) = app.menu() else {
        return Ok(());
    };

    // This is adding a submenu inside the macOS "app menu", the leftmost one
    if let Some(app_menu) = find(&root, "MyApp") {
        // Check if it exists before adding it
        if app_menu.get("the_submenu_id").is_none() {
            let submenu = menu(app, "the_submenu_id", "Your New Submenu")?;
            // Can insert at some position, or append, or prepend, etc
            app_menu.insert(&submenu, 1)?;
        }
    }

    Ok(())
}
