waylib is a Wayland compositor development library, based on qwlroots, provides a Qt-style development interface. It is designed to be deeply integrated with QtQuick, taking advantage of QtQuick's Scene Graphics model to simplify the complexity of window management. In waylib, it is possible to attach one or multiple Wayland Outputs to a QQuickWindow, and a corresponding Wayland Surface can be attached to a QQuickItem, allowing it to be mixed with QtQuick's graphics components and supporting QRHI for OpenGL and Vulkan compatibility in a single piece of code.
