Question 1

How do I install FTXUI using CMake?

Accepted Answer

Use CMake FetchContent as recommended in the README: declare the git repository and tag (e.g., v6.1.9), then link libraries like ftxui::component. This ensures version control without manual dependency management.

Question 2

FTXUI vs NCurses: which is better for terminal UIs?

Accepted Answer

FTXUI offers a modern, functional style with prebuilt components for faster development, while NCurses is more low-level and established but requires more boilerplate code. Choose FTXUI for declarative UIs and NCurses for fine-grained control.

Question 3

Can FTXUI handle mouse events?

Accepted Answer

Yes, FTXUI supports keyboard and mouse navigation, as mentioned in the features. This enables interactive elements like clickable menus and sliders in terminal applications.

Question 4

How to create custom components in FTXUI?

Accepted Answer

Extend the ftxui::Component class and implement Render and OnEvent methods. The documentation and examples provide guidance for building dynamic, reactive UIs with custom logic.

Question 5

Is FTXUI suitable for real-time terminal games?

Accepted Answer

It can be used for games, as shown in projects like TermBreaker, but performance is limited by terminal refresh rates. Best for turn-based or slower-paced games rather than fast-action simulations.

Question 6

What C++ version is required for FTXUI?

Accepted Answer

FTXUI requires C++20, especially for module support. Ensure your compiler supports this standard, as highlighted in the features for modern C++ development.
