Questions tagged [qwindow]

The QWindow class represents a window in the underlying windowing system.

A window that is supplied a parent becomes a native child window of their parent window.

An application will typically use QWidget or QQuickView for its UI, and not QWindow directly. Still, it is possible to render directly to a QWindow with QBackingStore or QOpenGLContext, when wanting to keep dependencies to a minimum or when wanting to use OpenGL directly. The Raster Window Example and OpenGL Window Example are useful reference examples for how to render to a QWindow using either approach.
