To support OpenGL/Vulkan, you must implement:
QMinimalIntegration::QMinimalIntegration(const QStringList ¶meters) qt qpa plugin
The is not a mere driver—it is the porting layer that makes Qt "write once, run anywhere" work. The moment your app calls QApplication::exec() , the QPA plugin owns your process's integration with the native OS. Understanding QT_QPA_PLATFORM and QT_DEBUG_PLUGINS will save you hours of deployment hell, and realizing you can replace it entirely opens up embedded and custom platform development. To support OpenGL/Vulkan
Notably, the higher-level visual style (QStyle) is part of QPA; QPA focuses strictly on the bridge between the application and the hardware/OS windowing layer. Common Qt QPA Plugins qt qpa plugin
