Struct MenuBar 

pub struct MenuBar {
    pub menus: Vec<BarMenu>,
}

The application menu: what a frame declares, in order (Core::declare_menu_bar).

Declared and not commanded, like the window title: a frame that declares none leaves the last one in force, and a frame that declares an empty bar takes it away. Where the platform owns a menu bar the driver hands this over (macOS: NSApp.mainMenu); everywhere else crate::widgets::menu_bar draws it, and each of its titles opens the ordinary Menu machinery — so the dropdown, its keyboard, its dismissal and its access tree are the ones already built for the context menu.

Fields

menus: Vec<BarMenu>

Implementations

impl MenuBar

pub fn new(menus: Vec<BarMenu>) -> MenuBar

pub fn from_value(v: &Value) -> Result<MenuBar, String>

A bar from plain data: a list of { label, items, enabled? }, whose items are the rows openMenu takes. A menu with no items is a shape error and not an empty menu: the two read the same on screen and only one of them was meant.

pub fn stray_keys(v: &Value) -> Vec<String>

MenuItem::stray_keys over every menu’s rows.

pub fn is_empty(&self) -> bool

Nothing declared: the bar the platform is asked to take away.

pub fn item(&self, menu: usize, item: usize) -> Option<&MenuItem>

The item at (menu, item), if it is there.

pub fn item_at(&self, menu: usize, path: &[usize]) -> Option<&MenuItem>

The item at path inside menu menu, through its submenus (MenuItem::at_path).
