pub fn new() -> MenubarState

State. For the specifics use the public fields menu and popup.

pub fn named(name: &'static str) -> MenubarState

New state with a focus name.

pub fn popup_active(&self) -> bool

Submenu visible/active.

pub fn set_popup_active(&mut self, active: bool)

Submenu visible/active.

pub fn set_popup_z(&mut self, z: u16)
