Re: [pygame] immediate mode not working?

["Brian Fisher" <brian@xxxxxxxxxxxxxxxxxxx>]

Blit works just fine for me - it's not a fill vs. blit thing - the problem you just experienced is something else - it's possible events need to get processed again? try calling pygame.event.get() when things don't seem to work (if you are not pumping the event loop, btw, you are not using pygame in a supported fashion, and the results are unpredictable)

anyways, I did the sequence of stuff below, and it all worked exactly as expected for me (demonstrating blits can work fine)

You are right, filling the screen seems to work, but not blitting to it.

The problem is that you need to tell SDL to process windows messages before your window can be used (any event getting function should do)

try this:
---------
import pygame
pygame.init()
screen = pygame.display.set_mode((400,300))
pygame.event.get()
screen.fill((255,255,255))
pygame.display.flip()
screen.fill((0,0,0))
pygame.display.flip()
---------

it worked in a command prompt console for me

As you can guess nothing happens on my pygame window, while using the MSDOS(the real) python.

Could we see the code?
