Re: [pygame] pygame from OS X command line

Re: [pygame] pygame from OS X command line | Re: [pygame] pygame from OS X command line
Hi again Bob,

Yes, I'm using current CVS pygame.

 From some more investigation, it seems there are two separate problems:

1) Error (1002) creating CGSWindow
This is unrelated to timing -- it happens (with vanilla CVS pygame)  
with the following script:
python2.4 -i -c "import pygame; pygame.init();screen =  
pygame.display.set_mode((468, 60))"

However, if I add 'import pygame.macosx;pygame.macosx.init()' before  
the set_mode, it works.  Just putting macosx.init() after the import  
in packager_imports() does not work; nor does just importing macosx  
earlier, without running macosx.init() explicitly.

Investigation shows that, with vanilla CVS pygame, neither macosx.init 
() nor pygame.packager_imports() is being called before the crash.  I  
can't work out how macosx.init() or pygame.packager_imports() are  
supposed to get called normally - my python is weak.

Currently, I'm 'fixing' this with:
pygame.__init__.py:
_check_darwin(): Add
import pygame.macosx
macosx.init()

packager_imports(): Remove:
import pygame.macosx

Will this cause problems?

2) Timing issue
If I fix problem 1, the script above works.  But if I start  
python2.4, wait a second or two, and then type the same commands  
manually,  I get the following error:

Traceback (most recent call last):
   File "<stdin> ", line 1, in ?
   File "/sw/lib/python2.4/site-packages/pygame/macosx.py", line 138,  
in init
     raise ImportError, "Can not access the window manager.  Use  
py2app or execute with the pythonw script."
ImportError: Can not access the window manager.  Use py2app or  
execute with the pythonw script.

This seems to be the error you were telling me about, and it's  
possible to work around it (by importing pygame quickly) like you  
mentioned.

Thanks for your help,

Ben
