What it is

Slint is a declarative GUI toolkit that compiles .slint markup files into native UIs for Rust, C++, JavaScript, and Python applications, supporting embedded systems, desktops, and mobile platforms. It separates UI design from business logic, enabling designers and developers to work in parallel while maintaining a lightweight, responsive experience across architectures. Monorepo structure with internal/backends/ containing pluggable platform implementations (Qt, Android via android-activity, Linux KMS, etc.), each with its own Cargo.toml and renderer choices (Skia, Vello, femtovg, software rendering). Android backend delegates to i-slint-renderer-skia and i-slint-core via workspace…

Start here

Open these first:

  • internal/backends/selector/lib.rs — Backend selection entry point that routes to platform-specific implementations (Qt, Winit, Android, Linux KMS) based on…
  • internal/backends/winit/lib.rs — Primary cross-platform desktop backend using Winit, handles event loop, window management, and input for Linux, macOS,…
  • internal/backends/qt/lib.rs — Qt-based desktop backend providing native widget integration and accessibility support via Qt Framework.
  • internal/backends/android-activity/lib.rs — Android backend implementation using android-activity crate for native app lifecycle and OpenGL rendering.
  • internal/backends/linuxkms/lib.rs — Embedded Linux backend supporting DRM/KMS display output with multiple renderer options (Skia, Femtovg, software).

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone the repository: git clone https://github.com/slint-ui/slint.git && cd slint. The project uses Rust (Cargo) as primary build system; verify Rust toolchain is installed. For Android backend specifically, examine `…

Daily commands:

Backend-specific: for Android (native-activity): cargo build --package i-slint-backend-android-activity --features native-activity,aa-06 --target aarch64-linux-android. For Qt backend: examine `internal/backends/qt/Ca…

…shortened for this brief.

Key cautions & unknowns

  • Android backend requires explicit feature selection: aa-05 or aa-06 for android-activity version (incompatible; pick one). NDK version is tied to android-activity version (ndk-08 with aa-05, ndk-09 with aa-06).…
  • Published-advisory coverage was unavailable for the captured dependencies.
  • Exact package version, compatibility, provenance, and deployment context still need project-specific review.
