Qt for HarmonyOS

Qt for HarmonyOS enables you to develop Qt applications for HarmonyOS devices.

Qt for HarmonyOS provides the platform integration, build and packaging support, and the platform plugin that connect the cross-platform Qt libraries (such as Qt Core, Qt GUI, Qt Quick, and Qt Widgets) to HarmonyOS. A Qt application is packaged into a HarmonyOS Ability Package (HAP) and runs on the device through the HarmonyOS platform plugin.

Key features and capabilities

• Cross-platform development. Write your application code once, typically a Qt Quick application with a C++ back-end, and deploy it on HarmonyOS alongside the other platforms that Qt supports, with minimal or no adjustments.
• Native performance. The Qt runtime is compiled for HarmonyOS, so it runs as native code on the device.
• Rich UI components. Use Qt Quick and Qt Quick Controls for responsive interfaces, or Qt Widgets for traditional widget-based UIs.
• C++ integration. Reuse existing C++ libraries and high-performance native code.
