//! This module contains internal structures and types used within the `weavetui_core` crate, primarily for managing component state and context.
//! These types are generally not intended for direct public consumption but are essential for the framework's internal workings.

use ratatui::layout::Rect;
use tokio::sync::mpsc::UnboundedSender;
use crate::event::Action;
use crate::theme::ThemeManager;
use crate::Component;

#[derive(Debug)]

    /// The rectangular area assigned to the component for rendering.
    pub area: Option<Rect>,
    /// A flag indicating whether the component is currently active.
    pub active: bool,
    /// An optional sender for dispatching actions to the application's event loop.
