Hi Paul.
For moving:
you can use lite_set_window_bounds(), which will do MoveTo if
width/height are unchanged.
In principle, need to call DirectFB-functions is a hole in the LiTE API.
For performance:
every LiTE window has a back buffer, so if you move the window, it will
not generate a 'client redraw'.
However, DirectFB does not do a bitblt internally on the display layer,
but requests a new copy of this back buffer to the display layer. This
avoids complex updates when you e.g. move a covered window. The update
speed depends a bit on how this copying is done, depending on your
system this might be hardware or software, and again depending, you
might avoid this by changing the memory allocation scheme (e.g. increase
the video buffer size, if available).

Hi,
I'm trying to move lite windows programatically, and it seems there is
no LiTE function for this (?), is it correct to assume I must call the
underlying DFBWindow Move/MoveTo functions to achieve that?
I had some performance problems with raw MoveTo, how is the moving
done on DFB? Should I set some draw/blit flags before moving?
regards,
