Struct cursive::views::Menubar

pub struct Menubar {
    pub autohide: bool,
    // some fields omitted

fn is_empty(&self) -> bool

Returns true if this menubar is empty.

fn get_subtree(&mut self, i: usize) -> Option<&mut MenuTree>

Returns the item at the given position.

Returns None if i > self.len()

fn find_subtree(&mut self, label: &str) -> Option<&mut MenuTree>

Looks for an item with the given label.

fn find_position(&mut self, label: &str) -> Option<usize>

Returns the position of the item with the given label.

Returns None if no such label was found.
