LCUI - A small C library for building user interfaces with C, XML and CSS

[LiaoMi]

Hi,

our time is popular for various frameworks, especially for building GUI interfaces. I would like to present for discussion one of them, similar to the one already published here UASM and UltraLight - http://masm32.com/board/index.php?topic=9223.0

LCUI - A small C library for building user interfaces with C, XML and CSS

Features
Written in C: Suitable for small applications written primarily in C.language designed for LCUI, it makes it easier to create interactive UIs.
Cross platform: Support for Windows and Linux, you can write Windows Desktop apps and Universal Windows Platform apps, as well as Linux Desktop apps.
XML + CSS: Includes XML and CSS parsers, you can use XML and CSS to describe interface structure and style.
Web-like development experience: Since the design and implementation of LCUI's functions, including layout, CSS, and renderer, are mostly referenced from MDN documents and some popular web front-end development libraries, its development experience and interface effects will have some similarities to web pages. If you already have experience writing web pages with HTML and CSS, it will be easier to get started.
Flexible: Support for adapting the interface to screens of different pixel densities by setting global scaling. Support for using screen density related sp and dp units to describe position and size of the elements.

Interesting projects that are implemented using this library
LC-Finder - An image annotation and object detection tool written in C - https://github.com/lc-soft/LC-Finder/releases and https://github.com/lc-soft/LC-Finder



The development of LCFinder is inseparable from the support of these projects:

LCUI — UI engine, provide graphical user interface support
LCUI.css — UI component library, provides basic styles and components for the graphical user interface
darknetlib — C bindings for darknet, provide image recognition support
