A template for a C++ application that's using Slint for the user interface and CMake for the build system.

This template helps you get started developing a C++ application with Slint as toolkit for the user interface. It demonstrates the integration between the .slint UI markup and C++ code, how to trigger react to callbacks, get and set properties and use basic widgets.

In order to use this template and build a C++ application, you need to install a few tools:

• cmake (3.21 or newer)
• A C++ compiler that supports C++ 20

If your target environment is Linux or Windows on an x86-64 architecture, then you may also opt into downloading one of our binary Slint packages. These are pre-compiled and require no further tools. You can find setup instructions and download links at

https://slint.dev/docs/cpp/cmake.html#install-binary-packages

Alternatively, this template will automatically download the Slint sources and compile them. This option requires you to install Rust by following the Rust Getting Started Guide. Once this is done, you should have the rustc compiler and the cargo build system installed in your path.

1. Download and extract the ZIP archive of this repository.
2. Rename the extracted directory and change into it:

   mv slint-cpp-template-main my-project
   cd my-project
   

3. Configure with CMake

   mkdir build
   cmake -B build
   

4. Build with CMake

   cmake --build build
   

5. Run the application binary
   • Linux/macOS:

     ./build/my_application
     

   • Windows:

     build\my_application.exe
     

We recommend using an IDE for development, along with our LSP-based IDE integration for .slint files. You can also load this project directly in Visual Studio Code and install our Slint extension.

The android/ directory contains a Gradle wrapper around this CMake project that produces an Android APK.

Prerequisites:

• Android Studio with the Android SDK, NDK, and CMake (in SDK Tools).
• ANDROID_HOME and ANDROID_NDK_ROOT set in your environment.
• Rust (see above) plus the Android target:

  rustup target add aarch64-linux-android
  

To build and install on a connected device or running emulator:

cd android
./gradlew installDebug

The first build is slow because Slint and the Skia renderer are compiled from source. View application logs with:

adb logcat -s slint

To target additional ABIs, add them to abiFilters in android/build.gradle.kts and install the matching Rust targets (armv7-linux-androideabi, x86_64-linux-android, i686-linux-android).

See the Slint Android guide for more details.

We hope that this template helps you get started and you enjoy exploring making user interfaces with Slint. To learn more about the Slint APIs and the .slint markup language check out our online documentation.
