[Pythonmac-SIG] Calling a python objc class method from cocoa

[Saptarshi Guha]

Hello,
1) I tried your suggestion

@classmethod
     def setdefaulttimeout_(cls,timeout):
         NSLog("Timeout")

  and called

Class pySocket = NSClassFromString(@"pySocket");
[pySocket setdefaulttimeout:10];

And now I get a " Program received signal:  “EXC_BAD_ACCESS”. and gdb  
starts (Any information required?)

2)Also if I'm calling PyObjc NSObject subclasses from Objective C - i  
dont need to add underscores, i think the underscores are
only required if called Objective C methods (to get around the ":"),  
e.g I could add the following instance method
     def moo(self):
         NSLog("Moo")
Instantiate pySocket in objective-c and call [v moo] (v is a pySocket  
instance) and this works.

However, I cant seem to call the class method.

Pyobjc v 2
Regards
Saptarshi
