[Zope3-checkins] CVS: Zope3/src/zope/app/browser/component - interfacewidget.py:1.22

[Jim Fulton]

Update of /cvs-repository/Zope3/src/zope/app/browser/component
In directory cvs.zope.org:/tmp/cvs-serv14015

Modified Files:
	interfacewidget.py 
Log Message:

Added code to get the interface widget to only show interfaces that
satisfy the field constraint.

Added notation that multi-interface widgets should be used with
multi-interface fields, which we don't have yet.

Changed some string literal formatting to avoid confusing emacs Python
mode.
