Modules

FTXUI is organized into three modules, each building upon the previous:

1. @subpage module-screen — low-level rendering
2. @subpage module-dom — layout and composition
3. @subpage module-component — user interaction

---

[ @subpage module-screen ]

Defines:

• ftxui::Screen: a 2D grid of styled characters.
• ftxui::Pixel: the unit of rendering.
• Helpers like ftxui::Color and Dimension.

Use for direct terminal drawing and styling.

---

[ @subpage module-dom ]

Provides:

• ftxui::Element: a tree structure for layout and UI.
• Composable and responsive elements.
• Render() to draw onto a Screen.

Ideal for structured, styled UIs.

---

[ @subpage module-component ]

Adds:

• ftxui::Component: stateful, interactive widgets.
• Built-ins: Checkbox, Input, Menu, Button.
• Supports keyboard/cursor input and composition.

Use for interactive apps.

Modules can be used independently, or together: screen → dom → component.
