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.
