详细描述

访问透过 QOpenGLContext::nativeInterface ().

成员函数文档编制

`[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 () 会返回 QSurfaceFormat 描述此像素格式。

注意： 窗口的指定通过 window 必须将其像素格式设为兼容上下文格式。若未在属于窗口的任何设备上下文中调用 SetPixelFormat()，采纳上下文会失败。

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： 此函数要求 QGuiApplication instance is already created.
