Raumkraut.net: SurfaceWindow

SurfaceWindow

This is a pretty rough module, written in response to a random comment on #pygame, to allow programs written using pygame to utilise multiple windows.

The SurfaceWindow class acts as a proxy for a display surface of a child python+pygame process, passing method calls to the child and receiving responses and events back from it.

Features

Only dependent on Pygame and the Python standard library.
Semi-transparently acts like a normal surface object (ie. you shouldn't notice the difference unless you try to do something funky).
Methods of both the display surface and the child process' pygame.display module are made available directly through the SurfaceWindow object.
Pygame events occurring in child windows are fed into the parent's event queue in response to .process() calls. Such events have a 'window' attribute indicating which SurfaceWindow instance it was relayed from.

Usage example

import pygame

import surfwin

# Init main window

pygame.init()

main = pygame.display.set_mode((200, 200))

# Init secondary window

secondary = surfwin.SurfaceWindow((100, 100))

secondary.set_caption('Secondary pygame window')

# Something to blit to both windows, just to prove I'm not faking

smallred = pygame.Surface((10, 10))

smallred.fill((255, 0, 0))

# The main window gets smallred near the top-left corner

main.blit (smallred, (10, 10))

# The secondary window gets smallred in the middle

secondary.blit (smallred, (45, 45))

# Loop at 30 FPS, until we're told to quit

clock = pygame.time.Clock()

looping = True

while looping:

clock.tick(30)

# Prompt the secondary window to send events to us

secondary.process()

for event in pygame.event.get():

if getattr(event, 'window', None) is None:

print 'MAIN', event

else:

print 'SECOND', event

# Quit if any of our windows are closed.

if event.type == pygame.QUIT:

looping = False

pygame.display.flip()

secondary.flip()
