-
- \brief The QPlatformWindow class provides an abstraction for top-level windows.
-
- The QPlatformWindow abstraction is used by QWindow for all its top level windows. It is being
- created by calling the createPlatformWindow function in the loaded QPlatformIntegration
- instance.
-
- QPlatformWindow is used to signal to the windowing system, how Qt perceives its frame.
- However, it is not concerned with how Qt renders into the window it represents.
-
- Visible QWindows will always have a QPlatformWindow. However, it is not necessary for
- all windows to have a QBackingStore. This is the case for QOpenGLWidget. And could be the case for
- windows where some 3.party renders into it.
-
- The platform specific window handle can be retrieved by the winId function.
-
- QPlatformWindow is also the way QPA defines how native child windows should be supported
- through the setParent function.
-
- The only way to retrieve a QPlatformOpenGLContext in QPA is by calling the glContext() function
- on QPlatformWindow.
-
- \sa QBackingStore, QWindow
