Hi Lionel,
not quite sure I understand.
Windows (IDirectFBWindow) are, afaik, always "single" buffered, or
rather simply "buffered" (as opposed to what I believe X does, which
simply issues redraw requests). A window update is then nothing more
than a sequence of bitblt operations.
If you want to get rid of the bufferedness you have to access the layer
yourself, since DirectFB has currently no mechanism for redraws.

Hi all
I'm wondering whether it's possible to change a double buffered window
to a single buffered one
and vice and versa.
My idea is to display several applications, each one having its own
window, and I only want one
of them to have focus and be able to update its content. Therefor the
others windows are kind "frozen"
and won't update their backbuffered content. So I could save some
memory by changing them from
double buffered to single buffered.
Is it something possible with the current directfb version ?
