8e25a75b73 Allow a Dimension::Fit to extend beyond the terminal maximum height (#950)
For long tables (and other DOM elements), one may want the screen to render on dimensions higher than the terminal.  
Hence, this PR proposes a way to do so, with an optional parameter in the `Dimension::Fit` util function.

995a33ac89 Table: support initializer list constructor. (#915)
To avoid burdening the user with explicit type construction when using
the library, we can use a constructor that accepts an initializer list
(std::initializer_list). This allows users to pass initializer lists
directly without having to wrap them in
std::vector<std::vector<std::string>>. This resolves the ambiguous case
when the inner list contains only two elements.

5daedf79ad Enable raw keyboard input (#832)
In order for applications to receive all keyboard inputs, including the
Ctrl-C and Ctrl-Z, the raw input mode has been enabled. As result the
SIGINT will no longer be used, instead the keyboard Ctrl-C event is used
for exiting the framework, but only if no components has made use of it.

64436fc52b Checkbox button debounce (#774)
This fixes: https://github.com/ArthurSonzogni/FTXUI/issues/773

Dragging the mouse with the left button pressed now avoids activating multiple
checkboxes.

Add support for detecting mouse press transition. Added:
```cpp
// The previous mouse event.
Mouse Mouse::previous;

// Return whether the mouse transitionned from:
// released to pressed => IsPressed()
// pressed to pressed => IsHeld()
// pressed to released => IsReleased()
bool Mouse::IsPressed(Button button) const;
bool Mouse::IsHeld(Button button) const;
bool Mouse::IsReleased(Button button) const;
```
A couple of components are now activated when the mouse is pressed,
as opposed to released.

Changelog
=========
Next
====
### Doc
- Fix broken Doxygen output. See @markmandel in #1029.
- Use Doxygen awesome. Add our own theme.
- Break the documentation into several pages.
### Build
- Feature: Support C++20 modules.
This requires:
- Using the Ninja or MSVC generator
- A recent Clang/GCC/MSVC compiler.
- Cmake 3.28 or higher.
Usage:
```cpp
import ftxui;
import ftxui.component;
import ftxui.dom;
import ftxui.screen;
import ftxui.util;
```
Thanks @mikomikotaishi for PR #1015.
- Remove dependency on 'pthread'.
### Component
- Fix ScreenInteractive::FixedSize screen stomps on the preceding terminal
output. Thanks @zozowell in #1064.
- Fix vertical `ftxui::Slider`. The "up" key was previously decreasing the
value. Thanks @its-pablo in #1093 for reporting the issue.
6.1.9 (2025-05-07)
------------
### Build
If all goes well (pending), ftxui should appear in the Bazel central repository.
It can be imported into your project using the following lines:
**MODULE.bazel**
```bazel
bazel_dep(name = "ftxui", version = "6.1.9")
```
Thanks @robinlinden and @kcc for the reviews.
### dom
- Bugfix: Restore the `dbox` behavior from ftxui 5.0.0. To apply bgcolor
blending between the two layers, a new `dboxBlend` will be added.
6.1.8 (2025-05-01)
------------------
### Build
- Feature: Support `bazel` build system. See #1032.
Proposed by Kostya Serebryany @kcc
**BUILD.bazel**
```bazel
deps = [
// Depend on the whole library:
"@ftxui//:ftxui",
// Choose a specific submodule:
"@ftxui//:component",
"@ftxui//:dom",
"@ftxui//:screen",
]
```
### Component
- Bugfix: Fix a crash with ResizeableSplit. See #1023.
- Clamp screen size to terminal size.
- Disallow `ResizeableSplit` with negative size.
### Dom
- Bugfix: Disallow specifying a negative size constraint. See #1023.
6.0.2 (2025-03-30)
-----
### Component
- BugFix: Fix major crash on Windows affecting all components. See #1020
- BugFix: Fix focusRelative.
6.0.1 (2025-03-28)
-----
Same as v6.0.0.
Due to a problem tag v6.0.0 was replaced. This isn't a good practice and affect
developers that started using it in the short timeframe. Submitting a new
release with the same content is the best way to fix this.
See #1017 and #1019.

- Feature: Add `SliderOption::on_change`. This allows to set a callback when the
slider value changes. See #938.
- Bugfix: Handle `Dropdown` with no entries.
- Bugfix: Fix crash in `LinearGradient` due to float precision and an off-by-one
mistake. See #998.
### Dom
- Feature: Add `italic` decorator. For instance:
```cpp
auto italic_text = text("Italic text") | italic;
```
```cpp
auto italic_text = italic(text("Italic text"));
```
Proposed by @kenReneris in #1009.
- Feature: Add `hscroll_indicator`. It display an horizontal indicator
reflecting the current scroll position. Proposed by @ibrahimnasson in
[issue 752](https://github.com/ArthurSonzogni/FTXUI/issues/752)
- Feature: Add `extend_beyond_screen` option to `Dimension::Fit(..)`, allowing
the element to be larger than the screen. Proposed by @LordWhiro. See #572 and
#949.
- Feature: Add support for Selection. Thanks @clement-roblot. See #926.
- See `selectionColor` decorator.
- See `selectionBackgroundColor` decorator.
- See `selectionForegroundColor` decorator.
- See `selectionStyle(style)` decorator.
- See `selectionStyleReset` decorator.
- Breaking change: Change how "focus"/"select" are handled. This fixes the
behavior.
- Breaking change: `Component::OnRender()` becomes the method to override to
render a component. This replaces `Component::Render()` that is still in use
to call the rendering method on the children. This change allows to fix a
couple of issues around focus handling.
### Screen
- Feature: Add `Box::IsEmpty()`.

> This feature is still in development, and the API may change in future releases.
> Your contribution is needed to help us improve the compatibility and usability
> of C++20 modules in FTXUI. If you encounter any issues or have suggestions,
> please open an issue.
FTXUI experimentally supports
[C++20 modules](https://en.cppreference.com/w/cpp/language/modules) to reduce
compilation times and improve code organization. Each header has a
corresponding module.
Use the FTXUI_BUILD_MODULES option to build the FTXUI project itself to provide C++ 20 modules,
for example with CMake and Ninja:
```sh
cmake \
-DCMAKE_GENERATOR=Ninja \
-DFTXUI_BUILD_MODULES=ON \
..
ninja
```
> [!NOTE]
> To use modules, you need a C++20 compatible compiler, CMake version 3.20 or
> higher, and use a compatible generator like Ninja. Note that Makefile
> generators **do not support modules**.
Then, in your own code you can consume the modules and code as normal:
```cpp
import ftxui;
int main() {
auto screen = ftxui::ScreenInteractive::TerminalOutput();
auto button = ftxui::Button("Click me", screen.QuitClosure());
screen.Loop(button);
return 0;
}
```
Note, the `ftxui` convenience module which simply pulls together all the modules:
```cpp
export import ftxui.component;
export import ftxui.dom;
export import ftxui.screen;
export import ftxui.util;
```
You can instead import only the module(s) you need if desired.
To properly find and link the modules with CMake, use `target_link_libraries` to get the right
compiler, linker, etc. flags.
```cmake
target_link_libraries(my_executable
#...whatever...
PRIVATE ftxui::modules
)
```
### Module list
The modules directly reference the corresponding header, or a group of related
headers to provide a more convenient interface. The following modules
are available:
- `ftxui`
- `ftxui.component`
- `ftxui.component.Animation`
- `ftxui.component.CapturedMouse`
- `ftxui.component.Component`
- `ftxui.component.ComponentBase`
- `ftxui.component.ComponentOptions`
- `ftxui.component.Event`
- `ftxui.component.Loop`
- `ftxui.component.Mouse`
- `ftxui.component.Receiver`
- `ftxui.component.ScreenInteractive`
- `ftxui.component.Task`
- `ftxui.dom`
- `ftxui.dom.Canvas`
- `ftxui.dom.Deprecated`
- `ftxui.dom.Direction`
- `ftxui.dom.Elements`
- `ftxui.dom.FlexboxConfig`
- `ftxui.dom.LinearGradient`
- `ftxui.dom.Node`
- `ftxui.dom.Requirement`
- `ftxui.dom.Selection`
- `ftxui.dom.Table`
- `ftxui.screen`
- `ftxui.screen.Box`
- `ftxui.screen.Color`

# Install FTXUI
To set up FTXUI in your project, follow the [installation guide](installation.html), which provides instructions for multiple build systems and package managers.
# Minimal Example
Save the following code as `main.cpp`:
```cpp
#include <ftxui/dom/elements.hpp>
#include <ftxui/screen/screen.hpp>
#include <iostream>
int main() {
using namespace ftxui;
Element document = hbox({
text("left") | border,
text("middle") | border | flex,
text("right") | border,
});
auto screen = Screen::Create(Dimension::Full(), Dimension::Fit(document));
Render(screen, document);
screen.Print();
}
```
Build and run it using your preferred build system.
If unsure, start with one of the methods described in the [installation page](installation.html).
Expected output:
```
┌────┐┌────────────────────────────────────┐┌─────┐
│left││middle ││right│
└────┘└────────────────────────────────────┘└─────┘
```
# Starter Template
For a complete working project, clone the official starter repository:
```bash
git clone https://github.com/ArthurSonzogni/ftxui-starter
```
Follow the build instructions in the `README.md` of that repository.

@page installation_bazel Bazel
FTXUI can be integrated into your project using [Bazel](https://bazel.build)
with Bzlmod (Bazel modules).
The library is registered in the [Bazel Central Registry](https://registry.bazel.build/modules/ftxui)
**MODULE.bazel**
```starlark
bazel_dep(name = "ftxui", version = "6.1.9")
```
**BUILD.bazel**
```starlark
cc_binary(
name = "main",
srcs = ["main.cpp"],
deps = [
"@ftxui//:component",
"@ftxui//:dom",
"@ftxui//:screen",
],
)
```
## Starter Project
You can use the official Bazel starter project for a minimal working setup:

@page installation_cmake CMake
@tableofcontents
This page explains how to depend on FTXUI using [CMake](https://cmake.org).
# Methods of Integration
## Using FetchContent
This approach downloads FTXUI at configure time and doesn't require a system-wide install.
```cmake
include(FetchContent)
FetchContent_Declare(ftxui
GIT_REPOSITORY https://github.com/ArthurSonzogni/FTXUI
GIT_TAG v6.1.9 # Replace with a version, tag, or commit hash
)
FetchContent_MakeAvailable(ftxui)
add_executable(main main.cpp)
target_link_libraries(main
PRIVATE ftxui::screen
PRIVATE ftxui::dom
PRIVATE ftxui::component
)
```
This ensures reproducible builds and easy dependency management.
## Using find_package
If FTXUI is installed system-wide or via a package manager (e.g. vcpkg or Conan), you can use:
```cmake
find_package(ftxui REQUIRED)
add_executable(main main.cpp)
target_link_libraries(main
PRIVATE ftxui::screen
PRIVATE ftxui::dom
PRIVATE ftxui::component
)
```
Make sure the package is visible in your `CMAKE_PREFIX_PATH`.
## Using git submodule
You can also add FTXUI as a [Git submodule](https://git-scm.com/book/en/v2/Git-Tools-Submodules), keeping it as part of your repository:
```cmake
git submodule add https://github.com/ArthurSonzogni/FTXUI external/ftxui
git submodule update --init --recursive
```
When cloning a repository that already includes FTXUI as a submodule, make sure to fetch submodules with:
```
git clone --recurse-submodules <your-repo>
# Or, if already cloned:
git submodule update --init --recursive
```
Then in your `CMakeLists.txt`:
```cmake
add_subdirectory(external/ftxui)
add_executable(main main.cpp)
target_link_libraries(main
PRIVATE ftxui::screen
PRIVATE ftxui::dom
PRIVATE ftxui::component
)
```
This approach works well if you want to vendor FTXUI in your own repository.
# Optional CMake Flags
FTXUI supports the following CMake options:
| Option | Description | Default |
| --------------------------------- | ----------------------------- | ------- |
| FTXUI_BUILD_EXAMPLES | Build bundled examples | OFF |
| FTXUI_BUILD_DOCS | Build the documentation | OFF |
| FTXUI_BUILD_TESTS | Enable tests | OFF |
| FTXUI_ENABLE_INSTALL | Generate install targets | ON |
| FTXUI_MICROSOFT_TERMINAL_FALLBACK | Improve Windows compatibility | ON/OFF |
To enable an option:
```
cmake -DFTXUI_BUILD_EXAMPLES=ON ..
```
# Verifying Integration
To confirm the setup is working, build and run a minimal example.

@page installation_conan Conan
@tableofcontents
FTXUI can be easily obtained and integrated into your project using the Conan package manager.
## Prerequisites
First, ensure that Conan is installed on your system. If not, you can install it via pip:
```powershell
pip install conan
```
Conan often works in tandem with CMake, so you will need to have CMake installed as well. Once you have confirmed both Conan and CMake are installed, create a project directory, for example, `ftxui-demo`:
```powershell
mkdir C:\ftxui-demo
cd C:\ftxui-demo
```
## Configuration
After ensuring your environment is set up correctly, create a Conan configuration file `conanfile.txt`. This file is used to declare your project's dependencies. The community-maintained package for FTXUI can be found on [Conan Center](https://conan.io/center/recipes/ftxui).
> [!note]
> This is an unofficial build script. This means it is not maintained by the FTXUI
> team but by the community. The package maintainer appears to actively update it
> to the latest releases. Many thanks to the maintainer for their work!
@todo If you are familiar with the process, please consider adding an "official" build script to Conan Center.
This could be a GitHub Action that automatically updates Conan Center upon new releases.
```ini
[requires]
ftxui/6.0.2
[generators]
CMakeDeps
CMakeToolchain
[layout]
cmake_layout
```
## Install Dependencies and Build
Once configured, run the following command to install FTXUI and its dependencies:
```powershell
conan install . --output-folder=build --build=missing
```
This will download and install `ftxui/6.0.2` along with all its dependencies from Conan's remote repositories.
After the installation completes, you can test it by creating a `demo.cpp` file in your project directory:
```cpp
#include <ftxui/screen/screen.hpp>
#include <ftxui/dom/elements.hpp>
#include <iostream>
int main() {
using namespace ftxui;
auto document = hbox({
text(" Hello "),
text("FTXUI ") | bold | color(Color::Red),
text(" world! ")
});
auto screen = Screen::Create(Dimension::Full(), Dimension::Fit(document));
Render(screen, document);
std::cout << screen.ToString() << std::endl;
return 0;
}
```
If the test is successful, you can then create a `CMakeLists.txt` file in the project directory:
```cmake
cmake_minimum_required(VERSION 3.20)
project(ftxui-demo)
# Set the C++ standard
set(CMAKE_CXX_STANDARD 20)
# Find the FTXUI package installed via Conan
find_package(ftxui CONFIG REQUIRED)
# Create the executable
add_executable(demo demo.cpp)
# Link the executable to the FTXUI library
target_link_libraries(demo PRIVATE ftxui::component)
```
@todo 考虑到中国多数地区使用Conan很有可能遇到各种网络问题我想做一个定制的版本说明但是我对conan的了解有限再加上没有找到合适的资料因此这个计划短暂的被搁置了如果您知道方法欢迎在[中文版本](xiaoditx.girhub.io/public/docs/ftxui%E4%B8%AD%E6%96%87%E7%BF%BB%E8%AF%91/installation/conan/)的下方留下评论以提醒我

**FTXUI** is simple cross-platform C++ library for terminal based user interfaces!
# Feature
* Functional style. Inspired by
[1](https://hackernoon.com/building-reactive-terminal-interfaces-in-c-d392ce34e649?gi=d9fb9ce35901)
and [React](https://reactjs.org/)
* No dependencies
* **Cross platform**.
* Simple and elegant syntax (in my opinion)
* Keyboard & mouse navigation.
* Support for [UTF8](https://en.wikipedia.org/wiki/UTF-8) and [fullwidth chars](https://en.wikipedia.org/wiki/Halfwidth_and_fullwidth_forms) (→ 测试)
* Support for animations. [Demo 1](https://arthursonzogni.github.io/FTXUI/examples/?file=component/menu_underline_animated_gallery), [Demo 2](https://arthursonzogni.github.io/FTXUI/examples/?file=component/button_style)
* Support for drawing. [Demo](https://arthursonzogni.github.io/FTXUI/examples/?file=component/canvas_animated)
* Learn by [examples](#documentation), and [tutorials](#documentation)
* Multiple build system and packages:
* Good practices: documentation, tests, fuzzers, performance tests, automated CI, automated packaging, etc...
# Example
```cpp
#include <ftxui/dom/elements.hpp>
#include <ftxui/screen/screen.hpp>
#include <iostream>
int main() {
using namespace ftxui;
// Create a simple document with three text elements.
Element document = hbox({
text("left") | border,
text("middle") | border | flex,
text("right") | border,
});
// Create a screen with full width and height fitting the document.
auto screen = Screen::Create(
Dimension::Full(), // Width
Dimension::Fit(document) // Height
);
// Render the document onto the screen.
Render(screen, document);
// Print the screen to the console.
screen.Print();
}
```
Expected output:
```
┌────┐┌────────────────────────────────────┐┌─────┐
│left││middle ││right│
└────┘└────────────────────────────────────┘└─────┘
```

# Introduction {#introduction}
Welcome to the FTXUI documentation!
This is a brief tutorial. You are also encouraged to self-learn by reading the
[examples](./examples.html).
@tableofcontents
**Short example**
To build a single frame, you need create an `ftxui::Element`, and display it on
a `ftxui::Screen`.
**main.cpp**
```cpp
#include <ftxui/dom/elements.hpp>
#include <ftxui/screen/screen.hpp>
#include <iostream>
int main(void) {
using namespace ftxui;
// Define the document
Element document =
hbox({
text("left") | border,
text("middle") | border | flex,
text("right") | border,
});
auto screen = Screen::Create(
Dimension::Full(), // Width
Dimension::Fit(document) // Height
);
Render(screen, document);
screen.Print();
return EXIT_SUCCESS;
}
```
**output**

target_link_libraries(ftxui-starter
PRIVATE ftxui::screen
PRIVATE ftxui::dom
PRIVATE ftxui::component # Not needed for this example.
)
```
Subsequently, you build the project in the standard fashion as follows:
```bash
mkdir build && cd build
cmake ..
make
./main
```
# List of modules. {#modules}
The project is comprised of 3 modules:
1. **ftxui/screen** defines a `ftxui::Screen`, a grid of `ftxui::Pixel`.
2. **ftxui/dom** is the main module. It defines a hierarchical set of
`ftxui::Element`. An element draws something on the `ftxui::Screen`. It is
responsive to the size of its container.
3. **ftxui/component** The module is required if your program needs to respond
to user input. It defines a set of `ftxui::Component`. These components can
be utilized to navigate using the arrow keys *and/or* cursor. There are
several builtin widgets like checkbox/inputbox/etc to interact with. You can
combine them, or even define your own custom components.
# screen {#module-screen}
This is the visual element of the program. It defines a `ftxui::Screen`, which
is a grid of `ftxui::Pixel`. A Pixel represents a Unicode character and its
associated style (bold, colors, etc.). The screen can be printed as a string
using `ftxui::Screen::ToString()`. The following example highlights this
process:
```cpp
#include <ftxui/screen/screen.hpp>
#include <iostream>
int main(void) {
using namespace ftxui;
auto screen = Screen::Create(Dimension::Fixed(32), Dimension::Fixed(10));
auto& pixel = screen.PixelAt(9,9);
pixel.character = U'A';
pixel.bold = true;
pixel.foreground_color = Color::Blue;
std::cout << screen.ToString();
return EXIT_SUCCESS;
}
```
# dom {#module-dom}
This module defines a hierarchical set of `ftxui::Element`. An element manages
the layout and can be responsive to the terminal dimension changes. Note the
following example where this module is used to create a simple layout with a
number of operators:
**Example:**
```cpp
// Define the document
Element document = vbox({
text("The window") | bold | color(Color::Blue),
gauge(0.5)
text("The footer")
});
// Add a border, by calling the `ftxui::border` decorator function.
document = border(document);
// Add another border, using the pipe operator.
document = document | border.
// Add another border, using the |= operator.
document |= border
```
**List of elements**
The list of all elements are included and can be accessed by including the
corresponding header file:
```cpp
#include <ftxui/dom/elements.hpp>
```
\include ftxui/dom/elements.hpp
## text ## {#dom-text}
The most simple widget. It displays a text.
```cpp
text("I am a piece of text");
```
```bash
I am a piece of text.
```
## vtext {#dom-vtext}
Identical to `ftxui::text`, but displayed vertically.
Code:
```cpp
vtext("HELLO");
```
Terminal output:
```bash
H
E
L
L
O
```
## paragraph {#dom-paragraph}
Similar to `ftxui::text`, but the individual word are wrapped along multiple
lines, depending on the width of its container.
Sample Code:
```cpp
paragraph("A very long text")

Element paragraphAlignLeft(std::string text);
Element paragraphAlignRight(std::string text);
Element paragraphAlignCenter(std::string text);
Element paragraphAlignJustify(std::string text);
```
## border {#dom-border}
Adds a border around an element.
Code:
```cpp
border(text("The element"))
```
Terminal output:
```bash
┌───────────┐
│The element│
└───────────┘
```
You can achieve the same behavior by using the pipe operator.
Code:
```cpp
text("The element") | border
```
Border also comes in a variety of styles as shown below:
```cpp
Element border(Element);
Element borderLight(Element);
Element borderHeavy(Element);
Element borderDouble(Element);
Element borderRounded(Element);
Element borderEmpty(Element);
Decorator borderStyled(BorderStyle);
Decorator borderWith(Pixel);
```
## window ## {#dom-window}
A `ftxui::window` is a `ftxui::border`, but with an additional header. To add a
window around an element, wrap it and specify a string as the header.
Code:
```cpp
window("The window", text("The element"))
```
Terminal output:
```bash
┌The window─┐
│The element│
└───────────┘
```
## separator {#dom-separator}
Displays a vertical/horizontal line to visually split the content of a
container in two.
Code:
```cpp
border(
hbox({
text("Left"),
separator(),
text("Right")
})
)
```
Terminal output:
```bash
┌────┬─────┐
│left│right│
└────┴─────┘
```
Separators come in a variety of flavors as shown below:
```cpp
Element separator(void);
Element separatorLight();
Element separatorHeavy();
Element separatorDouble();
Element separatorEmpty();
Element separatorStyled(BorderStyle);
Element separator(Pixel);
Element separatorCharacter(std::string);

Color background,
Color foreground);
```
## gauge {#dom-gauge}
It constitutes a gauge. It can be used to represent a progress bar.
Code:
```cpp
border(gauge(0.5))
```
Teminal output:
```bash
┌────────────────────────────────────────────────────────────────────────────┐
│██████████████████████████████████████ │
└────────────────────────────────────────────────────────────────────────────┘
```
Gauges can be displayed in many orientations as shown below:
```cpp

## Colors {#dom-colors}
Most terminal consoles can display colored text and colored backgrounds. FTXUI
supports every color palette:
```cpp
Decorator color(Color);
Decorator bgcolor(Color);
```
Color [gallery](https://arthursonzogni.github.io/FTXUI/examples_2dom_2color_gallery_8cpp-example.html):
![image](https://user-images.githubusercontent.com/4759106/147248595-04c7245a-5b85-4544-809d-a5984fc6f9e7.png)
### Palette16 #{#dom-colors-palette-16}
On most terminals the following colors are supported:
- Default
- Black
- GrayDark
- GrayLight
- White
- Blue
- BlueLight
- Cyan
- CyanLight
- Green
- GreenLight
- Magenta
- MagentaLight
- Red
- RedLight
- Yellow
- YellowLight
Example use of the above colors using the pipe operator:
```cpp
text("Blue foreground") | color(Color::Blue);
text("Blue background") | bgcolor(Color::Blue);
text("Black on white") | color(Color::Black) | bgcolor(Color::White);
```
### Palette256 #{#dom-colors-palette-256}
On terminal supporting 256 colors.
@htmlonly
<script id="asciicast-OAUc3n6QrkmrLt7XEEb8AzbLt" src="https://asciinema.org/a/OAUc3n6QrkmrLt7XEEb8AzbLt.js" async></script>
@endhtmlonly
```cpp
text("HotPink") | color(Color::HotPink);
```
### TrueColor #{#dom-colors-true-color}
On terminal supporting trueColor, you can directly use the 24bit RGB color
space:
Use the constructors below to specify the **RGB** or **HSV** values for your
color:
There are two constructors:
```cpp
ftxui::Color::RGB(uint8_t red, uint8_t green, uint8_t blue);
ftxui::Color::HSV(uint8_t hue, uint8_t saturation, uint8_t value);
```

@endhtmlonly
## LinearGradient #{#dom-linear-gradient}
FTXUI supports linear gradient. Either on the foreground or the background.
```cpp
Decorator color(const LinearGradient&);
Decorator bgcolor(const LinearGradient&);
```
A `ftxui::LinearGradient` is defined by an angle in degree, and a list of color
stops.
```cpp
auto gradient = LinearGradient()
.Angle(45)
.AddStop(0.0, Color::Red)
.AddStop(0.5, Color::Green)
.AddStop(1.0, Color::Blue);
```
You can also use simplified constructors:
```cpp
LinearGradient(Color::Red, Color::Blue);
```
```cpp
LinearGradient(45, Color::Red, Color::Blue);
```
See [demo](https://arthursonzogni.github.io/FTXUI/examples/?file=component/linear_gradient_gallery).
## Style {#dom-style}
In addition to colored text and colored backgrounds. Many terminals support text
effects such as: `bold`, `dim`, `underlined`, `inverted`, `blink`.
```cpp
Element bold(Element);
Element dim(Element);
Element inverted(Element);
Element underlined(Element);
Element underlinedDouble(Element);
Element strikethrough(Element);
Element blink(Element);
Decorator color(Color);
Decorator bgcolor(Color);
Decorator colorgrad(LinearGradient);
Decorator bgcolorgrad(LinearGradient);
```
[Example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2style_gallery_8cpp-example.html)
![image](https://user-images.githubusercontent.com/4759106/147244118-380bf834-9e33-40df-9ff0-07c10f2598ef.png)
To use these effects, simply wrap your elements with your desired effect:
```cpp
underlined(bold(text("This text is bold and underlined")))
```
Alternatively, use the pipe operator to chain it on your element:
```cpp
text("This text is bold") | bold | underlined
```
## Layout {#dom-layout}
Enables elements to be arranged in the following ways:
- **Horizontally** with `ftxui::hbox`
- **Vertically** with `ftxui::vbox`
- **Inside a grid** with `ftxui::gridbox`
- **Wrapped along one direction** using the `ftxui::flexbox`.
[Example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2vbox_hbox_8cpp-example.html) using `ftxui::hbox`, `ftxui::vbox` and `ftxui::filler`.
![image](https://user-images.githubusercontent.com/4759106/147242524-7103b5d9-1a92-4e2d-ac70-b3d6740061e3.png)

Element can also become flexible using the the `ftxui::flex` decorator.
Code:
```cpp
hbox({
text("left") | border ,
text("middle") | border | flex,
text("right") | border,
});
```
Terminal output:
```bash
┌────┐┌─────────────────────────────────────────────────────┐┌─────┐
│left││middle ││right│
└────┘└─────────────────────────────────────────────────────┘└─────┘
```
Code:
```cpp
hbox({
text("left") | border ,
text("middle") | border | flex,
text("right") | border | flex,

# component {#module-component}
The `ftxui::component` module defines the logic that produces interactive
components that respond to user events (keyboard, mouse, etc.).
A `ftxui::ScreenInteractive` defines a main loop that renders a component.
A `ftxui::Component` is a shared pointer to a `ftxui::ComponentBase`. The latter defines:
- `ftxui::ComponentBase::Render()`: How to render the interface.
- `ftxui::ComponentBase::OnEvent()`: How to react to events.
- `ftxui::ComponentBase::Add()`: Construct a parent/child relationship
between two components. The tree of component is used to define how to
navigate using the keyboard.
`ftxui::Element` are used to render a single frame.
`ftxui::Component` are used to render dynamic user interface, producing multiple
frame, and updating its state on events.

![youtube-video-gif (3)](https://user-images.githubusercontent.com/4759106/147246982-1e821751-531c-4e1f-bc37-2fa290e143cd.gif)
Produced by: `ftxui::Dropdown()` from "ftxui/component/component.hpp"
## Slider {#component-slider}
Represents a slider object that consists of a range with binned intermediate
intervals. It can be created by `ftxui::Slider()`.
[Example](https://arthursonzogni.github.io/FTXUI/examples_2component_2slider_8cpp-example.html):
![image](https://user-images.githubusercontent.com/4759106/147249265-7e2cad75-082c-436e-affe-44a550c480ab.png)
Produced by: `ftxui::Slider()` from "ftxui/component/component.hpp"
## Renderer {#component-renderer}
Produced by: `ftxui::Renderer()` from \ref ftxui/component/component.hpp. This
component decorate another one by using a different function to render an
interface.
Example:
```cpp
auto inner = [...]
auto renderer = Renderer(inner, [&] {
return inner->Render() | border
});
```
`ftxui::Renderer` also supports the component decorator pattern:
```cpp
auto component = [...]
component = component
| Renderer([](Element e) { return e | border))
| Renderer(bold)
```
As a short hand, you can also compose a component with an element decorator:
```cpp
auto component = [...]
component = component | border | bold;
```
## CatchEvent {#component-catchevent}
Produced by: `ftxui::CatchEvent()` from \ref ftxui/component/component.hpp.
This component decorate others, catching events before the underlying component.
Examples:
```cpp
auto screen = ScreenInteractive::TerminalOutput();
auto renderer = Renderer([] {
return text("My interface");
});
auto component = CatchEvent(renderer, [&](Event event) {
if (event == Event::Character('q')) {
screen.ExitLoopClosure()();
return true;
}
return false;
});
screen.Loop(component);
```
The `ftxui::CatchEvent` can also be used as a decorator:
```cpp
component = component
| CatchEvent(handler_1)
| CatchEvent(handler_2)
| CatchEvent(handler_3)
;
```
## Collapsible {#component-collapsible}
Useful for visual elements whose visibility can be toggle on/off by the user.
Essentially, this the combination of the `ftxui::Checkbox()` and
`ftxui::Maybe()` components.
```cpp
auto collabsible = Collapsible("Show more", inner_element);
```
## Maybe {#component-maybe}
Produced by: `ftxui::Maybe()` from \ref ftxui/component/component.hpp.
This component can be utilized to show/hide any other component via a boolean or
a predicate.
Example with a boolean:
```cpp
bool show = true;
auto component = Renderer([]{ return "Hello World!"; });
auto maybe_component = Maybe(component, &show)
```
Example with a predicate:
```cpp
auto component = Renderer([]{ return "Hello World!"; });
auto maybe_component = Maybe(component, [&] { return time > 10; })
```
As usual, `ftxui::Maybe` can also be used as a decorator:
```cpp
component = component
| Maybe(&a_boolean)
| Maybe([&] { return time > 10; })
;
```
## Container {#component-container}
### Horizontal {#component-horizontal}
Produced by: `ftxui::Container::Horizontal()` from
"ftxui/component/component.hpp". It displays a list of components horizontally
and handle keyboard/mouse navigation.
### Vertical {#component-vertical}
Produced by: `ftxui::Container::Vertical()` from
"ftxui/component/component.hpp". It displays a list of components vertically
and handles keyboard/mouse navigation.
### Tab {#component-tab}
Produced by: `ftxui::Container::Tab()` from
"ftxui/component/component.hpp". It take a list of component and display only
one of them. This is useful for implementing a tab bar.
[Vertical](https://arthursonzogni.github.io/FTXUI/examples_2component_2tab_vertical_8cpp-example.html):

## ResizableSplit {#component-resizable-split}
It defines a horizontal or vertical separation between two children components.
The position of the split is variable and controllable using the mouse.
There are four possible splits:
- `ftxui::ResizableSplitLeft()`
- `ftxui::ResizableSplitRight()`
- `ftxui::ResizableSplitTop()`
- `ftxui::ResizableSplitBottom()`
from "ftxui/component/component.hpp"

## Force a frame redraw. {#component-force-redraw}
Typically, `ftxui::ScreenInteractive::Loop()` is responsible for drawing a new
frame whenever a new group of events (e.g keyboard, mouse, window resize, etc.)
has been processed. However, you might want to react to arbitrary events that
are unknown to FTXUI. To accomplish this, you must post events using
`ftxui::ScreenInteractive::PostEvent` (**this is thread safe**) via a thread.
You will have to post the event `ftxui::Event::Custom`.
Example:
```cpp
screen->PostEvent(Event::Custom);
```

# Slider {#component-slider}
Represents a slider object that consists of a range with binned intermediate
intervals. It can be created by `ftxui::Slider()`.

Produced by: `ftxui::Slider()` from "ftxui/component/component.hpp"
# Renderer {#component-renderer}
Produced by: `ftxui::Renderer()` from \ref ftxui/component/component.hpp. This
component decorate another one by using a different function to render an
interface.
Example:
```cpp
auto inner = [...]
auto renderer = Renderer(inner, [&] {
return inner->Render() | border
});
```
`ftxui::Renderer` also supports the component decorator pattern:
```cpp
auto component = [...]
component = component
| Renderer([](Element e) { return e | border))
| Renderer(bold)
```
As a short hand, you can also compose a component with an element decorator:
```cpp
auto component = [...]
component = component | border | bold;
```
# CatchEvent {#component-catchevent}
Produced by: `ftxui::CatchEvent()` from \ref ftxui/component/component.hpp.
This component decorate others, catching events before the underlying component.
Examples:
```cpp
auto screen = ScreenInteractive::TerminalOutput();
auto renderer = Renderer([] {
return text("My interface");
});
auto component = CatchEvent(renderer, [&](Event event) {
if (event == Event::Character('q')) {
screen.ExitLoopClosure()();
return true;
}
return false;
});
screen.Loop(component);
```
The `ftxui::CatchEvent` can also be used as a decorator:
```cpp
component = component
| CatchEvent(handler_1)
| CatchEvent(handler_2)
| CatchEvent(handler_3)
;
```
# Collapsible {#component-collapsible}
Useful for visual elements whose visibility can be toggled on or off by the
user. Essentially, this is the combination of the `ftxui::Checkbox()` and
`ftxui::Maybe()` components.
```cpp
auto collapsible = Collapsible("Show more", inner_element);
```
# Maybe {#component-maybe}
Produced by: `ftxui::Maybe()` from \ref ftxui/component/component.hpp.
This component can be utilized to show/hide any other component via a boolean or
a predicate.
Example with a boolean:
```cpp
bool show = true;
auto component = Renderer([]{ return "Hello World!"; });
auto maybe_component = Maybe(component, &show)
```
Example with a predicate:
```cpp
auto component = Renderer([]{ return "Hello World!"; });
auto maybe_component = Maybe(component, [&] { return time > 10; })
```
As usual, `ftxui::Maybe` can also be used as a decorator:
```cpp
component = component
| Maybe(&a_boolean)
| Maybe([&] { return time > 10; })
;
```
# Container {#component-container}
## Horizontal {#component-horizontal}
Produced by: `ftxui::Container::Horizontal()` from
"ftxui/component/component.hpp". It displays a list of components horizontally
and handles keyboard/mouse navigation.
## Vertical {#component-vertical}
Produced by: `ftxui::Container::Vertical()` from
"ftxui/component/component.hpp". It displays a list of components vertically
and handles keyboard/mouse navigation.
## Tab {#component-tab}
Produced by: `ftxui::Container::Tab()` from
"ftxui/component/component.hpp". It takes a list of components and displays
only one of them. This is useful for implementing a tab bar.
[Vertical](https://arthursonzogni.github.io/FTXUI/examples_2component_2tab_vertical_8cpp-example.html):

# ResizableSplit {#component-resizable-split}
It defines a horizontal or vertical separation between two children components.
The position of the split is variable and controllable using the mouse.
There are four possible splits:
- `ftxui::ResizableSplitLeft()`
- `ftxui::ResizableSplitRight()`
- `ftxui::ResizableSplitTop()`
- `ftxui::ResizableSplitBottom()`
from "ftxui/component/component.hpp"

# Force a frame redraw. {#component-force-redraw}
Typically, `ftxui::ScreenInteractive::Loop()` is responsible for drawing a new
frame whenever a new group of events (e.g keyboard, mouse, window resize, etc.)
has been processed. However, you might want to react to arbitrary events that
are unknown to FTXUI. To accomplish this, you must post events using
`ftxui::ScreenInteractive::PostEvent` (**this is thread safe**) via a thread.
You will have to post the event `ftxui::Event::Custom`.
Example:
```cpp
screen->PostEvent(Event::Custom);
```
If you don't need to process a new Event, you can use:
```cpp
screen->RequestAnimationFrame();
```
instead.

![title-img](https://nsm09.casimages.com/img/2025/05/31//2505310207423242518595347.png)
This module defines a hierarchical set of `ftxui::Element`. An element manages
the layout and can be responsive to the terminal dimension changes. Note the
following example where this module is used to create a simple layout with a
number of operators:
The @subpage module-dom-examples section provides a collection of examples.
**Example:**
```cpp
namespace ftxui {
...
// Define the document
Element document = vbox({
text("The window") | bold | color(Color::Blue),
gauge(0.5)
text("The footer")
});
// Add a border, by calling the `ftxui::border` decorator function.
document = border(document);
// Add another border, using the pipe operator.
document = document | border.
// Add another border, using the |= operator.
document |= border
...
}
```
**List of elements**
The list of all elements are included and can be accessed by including the
corresponding header file:
```cpp
#include <ftxui/dom/elements.hpp>
```
\include{strip} "ftxui/dom/elements.hpp"
# text # {#dom-text}
The most simple widget. It displays a text.
```cpp
text("I am a piece of text");
```
```bash
I am a piece of text.
```
# vtext {#dom-vtext}
Identical to `ftxui::text`, but displayed vertically.
Code:
```cpp
vtext("HELLO");
```
Terminal output:
```bash
H
E
L
L
O
```
# paragraph {#dom-paragraph}
Similar to `ftxui::text`, but the individual word are wrapped along multiple
lines, depending on the width of its container.
Sample Code:
```cpp
paragraph("A very long text")
```
![ezgif com-gif-maker (4)](https://user-images.githubusercontent.com/4759106/147251370-983a06e7-6f41-4113-92b8-942f43d34d06.gif)
For a more detailed example refer to [detailed example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2paragraph_8cpp-example.html). Paragraph also includes a number of other variants as shown below:
```cpp
namespace ftxui {
Element paragraph(std::string text);
Element paragraphAlignLeft(std::string text);
Element paragraphAlignRight(std::string text);
Element paragraphAlignCenter(std::string text);
Element paragraphAlignJustify(std::string text);
}
```
# border {#dom-border}
Adds a border around an element.
Code:
```cpp
border(text("The element"))
```
Terminal output:
```bash
┌───────────┐
│The element│
└───────────┘
```
> [!note]
> You can achieve the same behavior by using the pipe operator.
>
> Code:
> ```cpp
> text("The element") | border
> ```
Border also comes in a variety of styles as shown below:
```cpp
namespace ftxui {
Element border(Element);
Element borderLight(Element);
Element borderHeavy(Element);
Element borderDouble(Element);
Element borderRounded(Element);
Element borderEmpty(Element);
Decorator borderStyled(BorderStyle);
Decorator borderWith(Pixel);
}
```
# window # {#dom-window}
A `ftxui::window` is a `ftxui::border`, but with an additional header. To add a
window around an element, wrap it and specify a string as the header.
Code:
```cpp
window("The window", text("The element"))
```
Terminal output:
```bash
┌The window─┐
│The element│
└───────────┘
```
# separator {#dom-separator}
Displays a vertical/horizontal line to visually split the content of a
container in two.
Code:
```cpp
border(
hbox({
text("Left"),
separator(),
text("Right")
})
)
```
Terminal output:
```bash
┌────┬─────┐
│left│right│
└────┴─────┘
```
Separators come in a variety of flavors as shown below:
```cpp
namespace ftxui {
Element separator(void);
Element separatorLight();
Element separatorHeavy();
Element separatorDouble();
Element separatorEmpty();
Element separatorStyled(BorderStyle);
Element separator(Pixel);
Element separatorCharacter(std::string);
Element separatorHSelector(float left,
float right,
Color background,
Color foreground);
Element separatorVSelector(float up,
float down,
Color background,
Color foreground);
}
```
# gauge {#dom-gauge}
This is a visual element that represents a ratio of progress.
Code:
```cpp
border(gauge(0.5))
```
Terminal output:
```bash
┌────────────────────────────────────────────────────────────────────────────┐
│██████████████████████████████████████ │

```
Gauges can be displayed in many orientations as shown below:
```cpp
namespace {
Element gauge(float ratio);
Element gaugeLeft(float ratio);
Element gaugeRight(float ratio);
Element gaugeUp(float ratio);
Element gaugeDown(float ratio);
Element gaugeDirection(float ratio, GaugeDirection);

# Colors {#dom-colors}
Most terminal consoles can display colored text and colored backgrounds. FTXUI
supports every color palette:
```cpp
Decorator color(Color);
Decorator bgcolor(Color);
```
Color [gallery](https://arthursonzogni.github.io/FTXUI/examples_2dom_2color_gallery_8cpp-example.html):

## Palette16 #{#dom-colors-palette-16}
On most terminals the following colors are supported:
- Default
- Black
- GrayDark
- GrayLight
- White
- Blue
- BlueLight
- Cyan
- CyanLight
- Green
- GreenLight
- Magenta
- MagentaLight
- Red
- RedLight
- Yellow
- YellowLight
Example use of the above colors using the pipe operator:
```cpp
text("Blue foreground") | color(Color::Blue);
text("Blue background") | bgcolor(Color::Blue);
text("Black on white") | color(Color::Black) | bgcolor(Color::White);
```
## Palette256 #{#dom-colors-palette-256}
On terminal supporting 256 colors.

## TrueColor #{#dom-colors-true-color}
On terminal supporting trueColor, you can directly use the 24bit RGB color
space:
Use the constructors below to specify the **RGB** or **HSV** values for your
color:
There are two constructors:
```cpp
ftxui::Color::RGB(uint8_t red, uint8_t green, uint8_t blue);
ftxui::Color::HSV(uint8_t hue, uint8_t saturation, uint8_t value);
```

# LinearGradient #{#dom-linear-gradient}
FTXUI supports linear gradient. Either on the foreground or the background.
```cpp
Decorator color(const LinearGradient&);
Decorator bgcolor(const LinearGradient&);
```
A `ftxui::LinearGradient` is defined by an angle in degree, and a list of color
stops.
```cpp
auto gradient = LinearGradient()
.Angle(45)
.AddStop(0.0, Color::Red)
.AddStop(0.5, Color::Green)
.AddStop(1.0, Color::Blue);
```
You can also use simplified constructors:
```cpp
LinearGradient(Color::Red, Color::Blue);
```
```cpp
LinearGradient(45, Color::Red, Color::Blue);
```
See [demo](https://arthursonzogni.github.io/FTXUI/examples/?file=component/linear_gradient_gallery).
# Style {#dom-style}
In addition to colored text and colored backgrounds. Many terminals support text
effects such as: `bold`, `italic`, `dim`, `underlined`, `inverted`, `blink`.
```cpp
Element bold(Element);
Element italic(Element);
Element dim(Element);
Element inverted(Element);
Element underlined(Element);
Element underlinedDouble(Element);
Element strikethrough(Element);
Element blink(Element);
Decorator color(Color);
Decorator bgcolor(Color);
Decorator colorgrad(LinearGradient);
Decorator bgcolorgrad(LinearGradient);
```
[Example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2style_gallery_8cpp-example.html)

To use these effects, simply wrap your elements with your desired effect:
```cpp
underlined(bold(text("This text is bold and underlined")))
```
Alternatively, use the pipe operator to chain it on your element:
```cpp
text("This text is bold") | bold | underlined
```
# Layout {#dom-layout}
Enables elements to be arranged in the following ways:
- **Horizontally** with `ftxui::hbox`
- **Vertically** with `ftxui::vbox`
- **Inside a grid** with `ftxui::gridbox`
- **Wrapped along one direction** using the `ftxui::flexbox`.
[Example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2vbox_hbox_8cpp-example.html) using `ftxui::hbox`, `ftxui::vbox` and `ftxui::filler`.

![title-img](https://nsm09.casimages.com/img/2025/05/31//2505310207423242518595348.png)
The `ftxui::screen` module is the low-level foundation. It can be used
standalone, but it is primarily designed to be used together by
[ftxui::dom](module-dom.html) and [ftxui::component](module-component.html)
modules.
It provides a @ref ftxui::Screen.
---
# ftxui::Screen
The @ref ftxui::Screen class represents a 2D grid of styled characters that can
be rendered to a terminal.
It provides methods to create a screen, access pixels, and render elements.
You can access the individual cells (@ref ftxui::Pixel) of the screen using
the @ref ftxui::Screen::PixelAt method, which returns a reference
to the pixel at the specified coordinates.
**Example**
```cpp
#include <ftxui/screen/screen.hpp>
#include <ftxui/screen/color.hpp>
void main() {
auto screen = ftxui::Screen::Create(
ftxui::Dimension::Full(), // Use full terminal width
ftxui::Dimension::Fixed(10) // Fixed height of 10 rows
);
// Access a specific pixel at (10, 5)
auto& pixel = screen.PixelAt(10, 5);
// Set properties of the pixel.
pixel.character = U'X';
pixel.foreground_color = ftxui::Color::Red;
pixel.background_color = ftxui::Color::RGB(0, 255, 0);
pixel.bold = true; // Set bold style
screen.Print(); // Print the screen to the terminal
}
```
> [!note]
> If the coordinates are out of bounds, a dummy pixel is returned.
The screen can be printed to the terminal using @ref ftxui::Screen::Print() or
converted to a std::string with @ref ftxui::Screen::ToString().
<div class="tabbed">
- <b class="tab-title">Print()</b>
```cpp
auto screen = ...;
screen.Print();
```
- <b class="tab-title">ToString()</b>
```cpp
auto screen = ...;
std::cout << screen.ToString();
```
</div>
Note that you can reset the cursor position to the top-left corner of the
screen after printing by calling @ref ftxui::Screen::ResetCursorPosition().
**Example**
```cpp
auto screen = ...;
while(true) {
// Drawing operations:
...
// Print the screen to the terminal. Then reset the cursor position and the
// screen content.
std::cout << screen.ToString();
std::cout << screen.ResetCursorPosition(/*clear=*/true);
std::cout << std::flush;
// Sleep for a short duration to control the refresh rate.
std::this_thread::sleep_for(std::chrono::milliseconds(100));
}
```
---
# ftxui::Dimension
The @ref ftxui::Dimension utility controls screen sizing:
* `Dimension::Full()` — use full terminal width or height
* `Dimension::Fit(element)` — size to fit the rendered @ref ftxui::Element
* `Dimension::Fixed(n)` — use exactly `n` columns or rows
These values are to be passed to `ftxui::Screen::Create()`.
@ref ftxui::Screen::Create() provides two overloads:
- `Screen::Create(Dimension)` sets both width and height to the same kind of dimension
- `Screen::Create(Dimension width, Dimension height)` allows distinct control per axis
```cpp
auto screen = ftxui::Screen::Create(
ftxui::Dimension::Full(), // width
ftxui::Dimension::Fixed(10) // height
);
```
Once created, render an element and display the result:
```cpp
ftxui::Render(screen, element);
screen.Print();
```
---
# ftxui::Pixel
Each cell in the screen grid is a @ref ftxui::Pixel, which holds:
- Unicode codepoint.
- `character`
- @ref ftxui::Color:
- `foreground_color`
- `background_color`
- Booleans:
- `blink`
- `bold`
- `dim`
- `italic`
- `inverted` (swap foreground and background colors)
- `underlined`
- `underlined_double`
- `strikethrough`
```cpp
auto screen = ftxui::Screen::Create(
ftxui::Dimension::Fixed(5),
ftxui::Dimension::Fixed(5),
);
auto& pixel = screen.PixelAt(3, 3);
pixel.character = U'X';
pixel.bold = true;
pixel.foreground_color = ftxui::Color::Red;
pixel.background_color = ftxui::Color::RGB(0, 255, 0);
screen.Print();
```
> [!note]
> `PixelAt(x, y)` performs bounds checking and returns a reference to the pixel
> at the specified coordinate. If out-of-bounds, a dummy pixel reference is
> returned.
Each cell in the screen is a @ref ftxui::Pixel. You can modify them using:
```cpp
auto& pixel = screen.PixelAt(x, y);
pixel.character = U'X';
pixel.bold = true;
pixel.foreground_color = Color::Red;
```
---
# ftxui::Color
The @ref ftxui::Color class is used to define foreground and background colors for each @ref ftxui::Pixel.
It supports various color spaces and predefined palettes. FTXUI will
dynamically fallback to the closest available color in the terminal if the
requested color is not supported by the terminal.
**Color Spaces**
- **Default**: `ftxui::Color::Default` (terminal's default color)
- **16-color palette** [Demo](https://arthursonzogni.github.io/FTXUI/examples/?file=dom/color_gallery):
- `ftxui::Color::Black`,

# ftxui {#ftxui}
![title-img](https://nsm09.casimages.com/img/2025/05/30//2505300816063242518595251.jpg)
FTXUI is organized into three modules, each building upon the previous:
1. [ftxui/screen](#module-screen) - Low-level rendering
2. [ftxui/dom](#module-dom) - Layout and composition
3. [ftxui/component](#module-component) - User interaction
---
# ftxui/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.
<div class="section_buttons">
| Next |
|--------------------------------------:|
| [Documentation](module-screen.html) |
</div>
---
# ftxui/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.
<div class="section_buttons">
| Next |
|--------------------------------------:|
| [Documentation](module-dom.html) |
</div>
---
# ftxui/component
Adds:
- **`ftxui::Component`**: stateful, interactive widgets.
- Built-ins: `Checkbox`, `Input`, `Menu`, `Button`.
- Supports keyboard/cursor input and composition.
Use for interactive apps.
<div class="section_buttons">
| Next |
|--------------------------------------:|
| [Documentation](module-component.html) |
</div>
---
Modules can be used independently, or together: `screen → dom → component`.
