//! Focus management for stateful widgets.
//!
//! This module provides the [`Focusable`] trait, which allows widgets to track
//! whether they currently have input focus. Implementations are provided for
//! [`List`] and [`Table`].

use crate::{
    list::{List, ListItem},
    paragraph::Paragraph,
    table::{Row, Table},
};

/// A widget that can receive and report input focus.
pub trait Focusable {
    /// Sets the focus state and returns the modified widget.
    fn focus(self, focus: bool) -> Self;

    /// Returns `true` if the widget currently has focus.
    fn is_focused(&self) -> bool;
}
