Demo QtBindings

To clone the project, git-lfs is required.

The project demonstrates a multiplatform library using QtBindings with applications for Aurora OS (Qt) and Desktop (JVM/Compose Multiplatform).

Contents

• Multiplatform KMP library with shared logic
• Desktop application (Compose Multiplatform)
• Aurora OS application (Qt/QML)
• Project structure using independent subprojects (includeBuild)
• Automatic synchronization of KMP artifacts to Qt and JVM projects
• Root-level Gradle tasks for build orchestration
• Code formatting with Spotless

Demonstrated Features

• Platform detection: expect/actual mechanism for platform name (getTitle)
• Synchronous calls: retrieving shared state (DemoState.increment)
• Asynchronous calls: suspend functions with delays (increase)
• Error handling: exceptions from Kotlin coroutines caught in the host application
• Cancellation: graceful termination of long-running operations

Running the Desktop Application

From the project root:

./gradlew runAppDesktop

This will build the shared JVM artifacts and launch the Compose Multiplatform application.

Running the Aurora OS Application

From the project root:

./gradlew hintAuroraRun

This will build the shared native artifacts (.so, headers, .pro files) and print instructions for launching the Qt application in Aurora IDE.
