DFBCHECK(dfb->CreateSurface( dfb, &sdsc, &window_surface ) ); printf("!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"); DFBCHECK(dfb->CreateImageProvider( dfb,"dfblogo.png",&provider )); printf("$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$"); DFBCHECK(layer->CreateWindow( layer, &desc, &window ) ); printf("================================================="); DFBCHECK(window->GetSurface( window, &window_surface) ); // PROBLEM printf("......................................................................."); provider->RenderTo( provider, window_surface, NULL ); window_surface->Flip( window_surface, NULL, 0 ); provider->Release( provider ); Greetings from Dresden : ) > -----Ursprüngliche Nachricht----- > Von: "Nikita Egorov" <nik...@gmail.com> > Gesendet: 02.04.09 11:59:13 > An: Tu Duong Manh <tu...@web.de> > CC: directfb-users@directfb.org > Betreff: Re: [directfb-users] simple problem with layer,window,surface. > especially window->GetSurface > What for you commented the line layer->SetCooperativeLevel() ? > > You must do calls in followed sequence (pseudo code) > 1 window = dfb->CreateWindow(). > 2 window_surface = window->GetSurface() > 3 provider->RenderTo(window_surface) > > Otherwise you should return to source of df_window.c and remove > needless things step by step. > > 2009/4/2 Tu Duong Manh <tu...@web.de>: > > > Hello, > > > > i just try to unterstand how to create an window.
