img.Blit(main.GetSurf(),0,0);
SDL_FillRect( main.GetSurf(), NULL, 0 );
SDL_Flip(main.GetSurf());

this is my code for drawing a simple bitmap to the screen. is this order correct ? like ; 1. blit img 2. FillRect 3. SDL_Flip() as all i get is a black screen with this code ..

dont know SDL but try swapping 1 and 2

1. FillRect - This will clear the screen to black
2. img.blit - draw your image on the surface
3. Flip - bring that surface into view
