49 \class QEGLPlatformContext-
50 \brief An EGL context implementation.-
51 \since 5.2-
52 \internal-
53 \ingroup qpa-
54-
55 Implement QPlatformOpenGLContext using EGL. To use it in platform-
56 plugins a subclass must be created since-
57 eglSurfaceForPlatformSurface() has to be reimplemented. This-
58 function is used for mapping platform surfaces (windows) to EGL-
59 surfaces and is necessary since different platform plugins may-
60 have different ways of handling native windows (for example, a-
61 plugin may choose not to back every platform window by a real EGL-
62 surface). Other than that, no further customization is necessary.-
