[Pyobjc-dev] Calling Python code from Cocoa bundle

[<li...@po...>]

Hi,

I'm a python newbie and I'm trying to call a python method from within 
a Obj-c Cocoa bundle.

I've worked around the "undefined symbol" problem
( http://sourceforge.net/mailarchive/message.php?msg_id=7358512 ),
but python doesn't find my abstract Obj-C class and therefore won't let 
me subclass it:

> Traceback (most recent call last):
>   File "MyBundle.bundle/Contents/Resources/PythonGlue.py", line 36, in 
> ?
>     main()
>   File "MyBundle.bundle/Contents/Resources/PythonGlue.py", line 30, in 
> main
>     __import__(filename[:-3])
>   File "MyBundle.bundle/Contents/Resources/Test.py", line 7, in ?
>     class Test (Abstract):
> NameError: name 'Abstract' is not defined

Here's what I have:

PythonGlue.h, PythonGlue.m, PythonGlue.py from 
pyobjc-1.0/Doc/tutorial_embed/src/

### file: Abstract.h
@interface Abstract : NSObject
+ instantiateSubclassNamed: (NSString *) aClassName;
@end

@interface Abstract (Test)
- (void) hello;
@end

### file: Abstract.m
@implementation Abstract
  + instantiateSubclassNamed:(NSString*) aClassName
  {
     Class aClass = NSClassFromString(aClassName);
     return [[aClass alloc] init];
  }
  @end

### file: Test.py
from objc import YES, NO
from Foundation import *
from AppKit import *

DEBUG = 1

class Test (Abstract):
     def init(self):
	if DEBUG:
	    print "Test.init() called"
	return self
	
     def hello_(self, obj):
	if DEBUG:
	    print "Test.hello() called"

And in my bundle's main class:

     [[PythonGlue alloc] init];
     id test = [Abstract instantiateSubclassNamed:@"Test"];
     [test hello];


Thanks in advance,
-Ralph.
