[Interest] Setting current QOpenGLContext with an EGLContext

[Thomas Sevaldrud]

Hi,

I'm still working on the EGL PBuffer/DirectX integration through Qt that I
posted about last week :-)

Thanks to good help from this list I now have the PBuffer and DirectX
texture set up with the share handle. I also have a QOpenGLContext which I
have used to set up the EGL PBuffer. I don't have a QSurface though, since
my surface is the EGL PBuffer.

So, the question now is how do I make the QOpenGLContext current. (I need a
QOpenGLContext::currentContext() for QOpenGLFunctions and so on).

The code looks something like this:

    glContext_ = new QOpenGLContext;

    glContext_->setFormat(format);

    glContext_->create();



    ....


    QPlatformNativeInterface *nativeInterface =
QGuiApplication::platformNativeInterface();

    egl_display_ =
static_cast<EGLDisplay>(nativeInterface->nativeResourceForContext("eglDisplay",
glContext_));

    egl_context_ =
static_cast<EGLContext>(nativeInterface->nativeResourceForContext("eglContext",
glContext_));

    EGLConfig egl_config =
static_cast<EGLConfig>(nativeInterface->nativeResourceForContext("eglConfig",
glContext_));


    EGLint attribs[] = { ...


    };

    egl_pbuffer_ = eglCreatePbufferSurface(egl_display_, egl_config, attribs);



    ... D3D setup stuff...


    // Start rendering to PBuffer:


    eglMakeCurrent(egl_display_, egl_pbuffer_, egl_pbuffer_, egl_context_);


    ... Here I should like to set glContext current somehow...


Any ideas?
