[Pythoncard-users] iterating over components

[Michael S. <mik...@ya...>]

Am I correct in assuming the code below is the
standard way of iterating over components?

for component in self.components.itervalues():
   do stuff

The following seems more intuitive to me.

for component in self.components:
   do stuff

However, this causes a KeyError exception because
__iter__ is not defined. Is it ambiguous as to what
self.components should iterate over? If this makes
sense, an option would be to alias __iter__ in
WidgetDict (model.py) to UserDict.UserDict.itervalues.
