[wxpython-dev] Possible to derive from GC?

[Nitro]

Hello,

I've send this message yesterday, but it seems it did not get through,  
trying to sending it again.

1) Is it possible to derive my own class from wx.GraphicsContext or should  
I rather create a GC by itself and then delegate to it?

2) wx.lib.pubsub seems to have a bug. If I change the code at line 860  
class Foo2: to class Foo2(object): then the test breaks, because  
_paramMinCount does not work anymore. Is there any reason to use if tests  
in the _paramMinCount function? This is the code:

     if type(callableObject) is InstanceType:
         min, d = _paramMinCountFunc(callableObject.__call__.im_func)
         return min-1, d
     elif ismethod(callableObject):
         min, d = _paramMinCountFunc(callableObject.im_func)
         return min-1, d
     elif isfunction(callableObject):
         return _paramMinCountFunc(callableObject)
     else:
         raise 'Cannot determine type of callable: '+repr(callableObject)

I've rewritten it to the following code which passes the tests, also with  
new-style classes.

     try:
         func = callableObject.__call__.im_func
     except AttributeError:
         try:
             func = callableObject.im_func
         except AttributeError:
             try:
                 return _paramMinCountFunc(callableObject)
             except exc:
                 raise 'Cannot determine type of callable: %s' %  
repr(callableObject)
         else:
             min, d = _paramMinCountFunc(func)
             return min-1, d
     else:
         min, d = _paramMinCountFunc(func)
         return min-1, d

This code looks a bit clumsier than the original one. I don't see a much  
better way right now though.

3) The pubsub question leads me to another question: How to you want to  
handle SVN access? Should I create a branch which will be merged at the  
end of the project?
And how should I deal with patches/fixes which are not related to  
FloatCanvas (like the one to pubsub above)? Send in a patch on this  
mailing list and somebody reviews and accepts it?
