Slint C++ API

Slint ↗ is a UI toolkit that supports different programming languages. This site documents the C++ API.

The following sections explain how to integrate your .slint designs into your C++ application. The entry point is the .slint file containing the primary component you instantiate from C++.

Two integration options

Compiled ahead of time. Compile your Slint designs into C++ code that is built into your application. This gives the smallest memory footprint and the best performance. The CMake integration (slint_target_sources) makes the translation automatic; the generated code exposes an API to get and set properties, populate data models and handle callbacks. It uses types from the slint namespace, such as slint::SharedString and slint::Color.

Interpreted at run-time. Load .slint files dynamically at run-time. This is slower and uses more memory, but allows more dynamic user interfaces. The entry point is slint::interpreter::ComponentCompiler in the slint::interpreter namespace.
