## Introduction
|
||||
I **highly** recommand not to take too much time reading the tutorial. Instead,
|
||||
you should try to read the examples (in ./example/).

I recommand not to take too much time reading the tutorial. Instead,

|

The library is split in 3 parts:
|
||||
- [ftxui/screen/](../include/ftxui/screen/)
|
||||
|
||||
It defines a ftxui::Screen. A Screen is a grid of ftxui::Pixel. A Pixel contains a character and its associated style.
|
||||
Once the screen is ready, you can display it on the terminal.
|
||||
|
||||
- [ftuix/dom/](../include/ftxui/dom/)
|
||||
|
||||
These are a set of hierachical ftxui::Element declared in [ftxui/dom/elements.hpp](../ftxui/dom/elements.hpp).
|
||||
An element can render itself on the the Screen. It manage layout and is responsive to the Screen dimensions.
|
||||
|
||||
- [ftuix/component/](../include/ftxui/component)
|
||||
The part is only needed if you need to respond to the User input. It defines a set of ftxui::Component.
|
||||
The use can navigates using the arrow keys and interact with widgets like checkbox/inputbox/... You can make you own
|
||||
components.

### Style
|
||||
A terminal console can usually display colored text and colored background.
|
||||
The text can also have different effects: bold, dim, underlined, inverted,
|
||||
blink.

### Layout
|
||||
|
||||
These layout are similar to the HTML flexbox:
|
||||
* vbox (Vertical-box)
|
||||
* hbox (Horizontal-box)
|
||||
* dbox (Z-axis-box)
|
||||
They are used to compose all the elements together. Each
|
||||
children are put side by side. If the container is flexible, the extra space
|
||||
available will be shared among the remaining flexible children.
|
||||
|
||||
flex(element) can be used to make a non-flexible element flexible. filler() is a
|
||||
flexible empty element. You can use it align children on one side of the
|
||||
container.
|
||||
|
||||
An horizontal flow layout is implemented by:
|
||||
* hflow (Horizontal flow)
