It was discussed here:
http://groups.google.com/group/python_inside_maya/browse_thread/thread/f5a648c277f4fb66/ed12c99011ab151c
Here is an example with multiple arguments:
import maya.cmds as cmds
class Callback:
def __init__(self, func, *args, **kwargs):
self.func = func
self.args = args
self.kwargs = kwargs
def __call__(self, *args, **kwargs):
return self.func(*self.args, **self.kwargs)
cmds.window()
cmds.columnLayout()
cmds.button(label='Create Sphere', c=Callback(cmds.sphere,
name='HelloWorld', radius=10) )
cmds.showWindow()
