Implementations

impl<I: Md + Clone> MenuState<I>

pub fn set_intro<S: Into<String>>(&mut self, intro: S)

pub fn add_item(&mut self, action: I, key: Option<KeyCombination>)

pub fn clear_item_areas(&mut self)

pub fn select(&mut self, selection: usize)

pub fn on_key(&mut self, key: KeyCombination) -> (Option<I>, bool)

Handle a key event (not triggering the actions on their keys, only apply the menu mechanics).

Return an optional action and a bool telling whether the event was consumed by the menu.

pub fn item_idx_at(&self, x: u16, y: u16) -> Option<usize>

pub fn on_mouse_event( &mut self, mouse_event: MouseEvent, double_click: bool, ) -> Option<I>

handle a mouse event, returning the triggered action if any (on double click only)
