IntersticeUI is a C++20 GUI library for tools and editors: build the UI each frame in code, and the library keeps the state, lays it out with flexbox and grid, and draws it.

Getting started

• Building: what you need, cloning, building, and the CMake options.
• Running the demo and tests: the demo, the examples and the test suites.

Using the library

The guides live with the code, so they always match the version you have:

Guide
Overview	The application, the frame, IDs, Begin and End, units, errors
Controls	Every control, with its signature and an example
CSS	The selectors and properties the themes use
Integration	Adding the library to a build, runtime files, your own Vulkan device, window backend or loop

The API reference has the guides together with every header's documentation.
