is it possible to create an IDirectFBWindow without a surface? Or create a window with a surface, then at some point take its surface away and later attach a surface to it?
This may sound strange.. thus I'll explain. Every DirectFB-window has a surface attached to it.. When you have many windows, this can easily need a lot of memory. If I have a window that doesn't have focus and doesn't need to be updated until it gets focus again I could blit it onto the primary surface, remove its surface (and thus free the memory) and later when a focus event arrives recreate and redraw the surface (if I remove the complete IDirectFBWindow there won't be any more focus events ;). I think it can also be quite handy when trying to implement something like window minimizing.. then you didn't have to destroy the window when minimizing it, and having 20 large windows and 19 of them minmized wouldn't eat up memory for 20 surfaces..
Hope this was understandable.. if not just say it, I'll try to explain further.
greetings, Julian
