I need fullscreen mode as well, but am handling that anyways. I am
handing the primary surface off to evas and I think it's behaviour, or
lack thereof, is causing me problems.
Is there a difference with how DirectFB flips its surfaces if it's the
primary or not? The reason I ask is because if I set DSCAPS_PRIMARY
(using DFSCL_NORMAL or DFSCL_FULLSCREEN) the surface is updated
normally. If I do not set DSCAPS_PRIMARY, then my surface is not
updated. I did some playing around and I could flip the surface from
another application and it showed up.
I have been digging through the evas code, and have been working on it a
bit as well, and I see that it does not call flip() at all. I am now
assuming that this would be unneeded for the primary surface because of
the way DirectFB is managing it. It that correct? Please enlighten me. :)
I have also tried creating a window for the primary surface with
DSCAPS_PRIMARY like:
DFBWindowDescription wdesc;
wdesc.flags = DWDESC_SURFACE_CAPS | DWDESC_CAPS | DWDESC_WIDTH
| DWDESC_HEIGHT | DWDESC_PIXELFORMAT | DWDESC_POSX | DWDESC_POSY;
wdesc.caps = DWCAPS_ALPHACHANNEL | DWCAPS_NODECORATION;
wdesc.width = width;
wdesc.height = height;
wdesc.pixelformat = DSPF_ARGB;
wdesc.posx = win_x;
wdesc.posy = win_y;
wdesc.surface_caps = DSCAPS_PRIMARY;
DFBCHECK(layer->CreateWindow(layer, &wdesc, &window),
"CreateWindow");
DFBCHECK(window->GetSurface(window, &primary), "GetSurface");
DFBCHECK(window->SetOpacity(window, 0xff), "SetOpacity");
But, I am having the same problem with it not flipping.
Thanks,
