LCUI is a user interface development library written in C, allowing you to create simple desktop applications using C, XML, and CSS. It supports traditional Win32 desktop applications and Windows Universal Apps, with primary focus on Windows systems. Future versions may expand support for Linux systems. If you have a foundation in C programming and experience in web development, you will find it easier to get started with LCUI, as its handling of XML, CSS, and element layout bears some similarities to web browsers. You can refer to the example code on the left to understand the basic effects.

Software Highlights

C Language Development: LCUI is primarily written in C, making it suitable for developers who prefer lightweight applications and those who are already familiar with C programming.
