[Pythonmac-SIG] pyui font troubles

[David Hill]

Hi,

I'm relatively new to Python and I'm trying to work through some  
examples in Sean Riley's "Game Programming with Python" book.  
Unfortunately, I'm having some trouble with most of the examples that  
use his pyui library.

It looks like the examples fail when trying to create a font object  
for the arial font. I took a look in the pyui code that creates the  
font (using pygame) and it has this suspicious line:

>  faceFile = os.environ['WINDIR'] + "/Fonts/" + fontRegistery[faceFile]

where fontRegistery[faceFile] == "arial.ttf"

That didn't fill me with a great deal of confidence (since it  
produces a KeyError exception on WINDIR), so I tried a quick hack:

>             if os.environ.has_key( 'WINDIR' ):
>                 faceFile = os.environ['WINDIR'] + "/Fonts/" +  
> fontRegistery[faceFile]
>             else:
>                 faceFile = "/Library/Fonts/Arial"

That gets me the bus error shown below. Clearly, the font format on  
Mac OS X isn't what pygame is expecting.

Has anybody else had any luck getting the code from this book to work?

The error in the console looks like this:

> davidh% /usr/local/bin/pythonw terrainView.py

> sans ms': 'comic.ttf', 'times new roman': 'times.ttf'} arial

The stack crawl from the crash report looks like this:

Does anybody have any ideas or suggestions? Is pyui just not Mac (or  
Linux, evidently) friendly? Could I have screwed up my installation  
of Python 2.4 somehow?


Thanks,

Dave
