Hi Mandeep, I had a quick look at the wiki which says the DFBGL is not used. I can see there is some related code in the DFB QPA but I don't see it being used.
I think The "other EGL - OpenGL integration" mentioned on the wiki would require some tweaking into qdirectfb_egl.cpp or perhaps even at egl library. For now it doesn't even compile for me (seems my directfb libs are a tad too old and missing an enum) but foremost the mesa egl API I'm using doesn't appreciate the m_eglSurface = eglCreateWindowSurface(dfbScreen->eglDisplay(), config, dfbSurface(), NULL); where the NativeWindowType is "IDirectFbSurface*". thanks for the replies, Juha 2013/8/6 Mandeep Sandhu <mandeepsandhu....@gmail.com> > Some more info on the status of DirectFB with Qt5: > http://qt-project.org/wiki/DirectFBAndQt > > -mandeep > > > > On Tue, Aug 6, 2013 at 2:30 PM, Mandeep Sandhu < > mandeepsandhu....@gmail.com> wrote: > >> During Qt 4 days, you could use qvfb (Q Virtual Frambuffer) for running >> applications built for Qt embedded.
