Struct MenuPath 

pub struct MenuPath(/* private fields */);

Which menu of a MenuBar is open, and how deep: the index of the open menu on the bar, then of the open submenu in it, and so on. Empty when every menu is closed.

Implementations

impl MenuPath

pub fn closed() -> Self

Every menu closed.

pub fn from_indices(indices: impl Into<Vec<usize>>) -> Self

The path of indices, from the bar down.

pub fn is_open(&self) -> bool

Whether any menu is open.

pub fn depth(&self) -> usize

How many menus are open: 1 for a menu off the bar, 2 with a submenu in it.

pub fn at(&self, level: usize) -> Option<usize>

Which entry is open at level — 0 the bar.

pub fn indices(&self) -> &[usize]

The indices, from the bar down.

pub fn opened(&self, level: usize, index: usize) -> Self

The path with entry index open at level, and whatever was open below it closed.

pub fn truncated(&self, level: usize) -> Self

The path with everything from level down closed: truncated(0) closes the lot.

pub fn up(&self) -> Self

One level fewer open: what Escape does.
