`[static]` QOpenGLContext QWGLContext:: fromNative ( HGLRC context* , HWND window , QOpenGLContext * shareContext = nullptr)

Adopts an WGL context 句柄。

The window is needed because the its pixel format will be queried. When the adoption is successful, QOpenGLContext::format () 會返迴 QSurfaceFormat 描述此像素格式。

注意： 窗口的指定通過 window 必須將其像素格式設為兼容上下文格式。若未在屬於窗口的任何設備上下文中調用 SetPixelFormat()，采納上下文會失敗。

Ownership of the created QOpenGLContext shareContext is transferred to the caller.

`[pure virtual]` HGLRC QWGLContext:: nativeContext () const

Returns the underlying context handle.

`[static]` HMODULE QWGLContext:: openGLModuleHandle ()

Returns the handle for the OpenGL implementation that is currently in use.

注意： 此函數要求 QGuiApplication instance is already created.
