Hi, Giuseppe Iannello,
The code you attached may be the initialization of DirectFB.
Maybe you should not use Flip here.
.....
main_surface->Flip(main_surface, NULL, DSFLIP_NONE);
.....
menu_surface->Flip(menu_surface, NULL, DSFLIP_NONE);
.....
You could download the DirectFB-examples, and the demo df_window.c will tell
you how to get what you want, I think.
Best regards,
chiachen

help needed=======
Hi everybody. I'm writing a small app for an embedded device.
I want a fixed background surface and 2 windows for menus/infos.
i wrote this test code, here the relevant part
--- dfb->SetCooperativeLevel (dfb, DFSCL_EXCLUSIVE);
/* Get a reference to the primary layer and set its cooperative level
to ADMINISTRATIVE, so we can manage it */
dfb->GetDisplayLayer (dfb, DLID_PRIMARY, &main_layer);
main_layer->SetCooperativeLevel (main_layer, DLSCL_ADMINISTRATIVE);
DFBDisplayLayerConfig main_layer_config;
main_layer_config.flags = DLCONF_BUFFERMODE;
main_layer_config.buffermode = DLBM_WINDOWS;
DFBSurfaceDescription main_surface_desc;
main_surface_desc.flags = DSDESC_CAPS;
main_surface_desc.caps = DSCAPS_PRIMARY;
dfb->CreateSurface (dfb, &main_surface_desc, &main_surface);
main_surface->SetColor(main_surface, 0xff, 0x00, 0x00, 0xff);
main_surface->FillRectangle(main_surface, 0, 0, 680, 384);
main_surface->Flip(main_surface, NULL, DSFLIP_NONE);
DFBWindowDescription menu_window_desc;
menu_window_desc.flags = DWDESC_WIDTH | DWDESC_HEIGHT | DWDESC_POSX |
DWDESC_POSY;
menu_window_desc.width = 100;
menu_window_desc.height = 100;
menu_window_desc.posx = 10;
menu_window_desc.posy = 10;
main_layer->CreateWindow (main_layer, &menu_window_desc, &menu_window);
menu_window->RaiseToTop (menu_window);
menu_window->GetSurface (menu_window, &menu_surface);
menu_surface->SetColor(menu_surface, 0x00, 0xff, 0x00, 0xff);
menu_surface->FillRectangle(menu_surface, 0, 0, 50, 50);
menu_surface->Flip(menu_surface, NULL, DSFLIP_NONE);

This way, I should have a red surface (background) and a small green rectangle,
but I can see just the red background.
What am I doing wrong?
Thanks for your help
