Struct ContextMenuExtras 

Source
pub struct ContextMenuExtras<Msg: Clone + 'static> {
    pub open_sub: Option<usize>,
    pub appear: f32,
    pub on_pick_sub: Option<Arc<dyn Fn(usize, usize) -> Msg + Send + Sync>>,
    pub on_hover: Option<Arc<dyn Fn(Option<usize>) -> Msg + Send + Sync>>,
}
Expand description

Capacidades extra opcionales para context_menu_view_ex: submenús (flyout), animación de aparición y hover. Su Default reproduce el menú clásico (sin animación ni submenús).

Fields§

§open_sub: Option<usize>

Índice del item-submenú desplegado (flyout). La app lo guarda y lo actualiza vía on_hover.

§appear: f32

Progreso de aparición 0..1 (fade + leve slide). 1.0 = fijo.

§on_pick_sub: Option<Arc<dyn Fn(usize, usize) -> Msg + Send + Sync>>

Click en un item de submenú: (parent_idx, child_idx).

§on_hover: Option<Arc<dyn Fn(Option<usize>) -> Msg + Send + Sync>>

Hover sobre un item raíz: Some(idx) si es submenú (abrir flyout), None si es item normal (cerrar). La app guarda el resultado en open_sub.
