This is how I use it in my __init__.py file in the product directory (ie. lib/python/Products/ProductX):

__init__.py file:

#####################################################################

__doc__ = 'Initialize the rs product.' __version__='$Revision: 1.1 $'[11:-2]

from ImageFile import ImageFile

misc_ = { 'Folder_icon.gif': ImageFile('img/Folder_icon.gif', globals()), 'dtmldoc.gif': ImageFile('img/dtmldoc.gif', globals()), }

import rs

def initialize(context): "Initialize the product." try: context.registerClass( rs.rs, constructors = (rs.manage_addrsForm, rs.manage_addrs) ) context.registerHelp() context.registerHelpTitle('Zope/rs 2000 Help') except: import sys, traceback, string type, val, tb = sys.exc_info() sys.stderr.write(string.join(traceback.format_exception(type, val, tb), '')) del type, val, tb

#####################################################################

This then allows me to do http://myhost/misc_/rs/Folder_icon.gif

Hope this helps :)

The use of misc_ in the __init__.py of a Product is deprecated for Product icons though; it is still useful for registering extra icons. As for your try/except construct, this one of the first things that Shane Hathaway made unnecessary by hardening the registration process. Exceptions in the initialize method are now logged or printed to stdout. Your code could be simplified to: from ImageFile import ImageFile misc_ = { 'Folder_icon.gif': ImageFile('img/Folder_icon.gif', globals()) } import rs def initialize(context): "Initialize the product." context.registerClass( rs.rs, icon='img/dtmldoc.gif', constructors=(rs.manage_addrsForm, rs.manage_addrs)) context.registerHelp() context.registerHelpTitle('Zope/rs 2000 Help') The rs.rs class can the also omit the icon property. -- Martijn Pieters | Software Engineer mailto:mj@digicool.com | Digital Creations http://www.digicool.com/ | Creators of Zope http://www.zope.org/ ---------------------------------------------

Ok, for which version? This __init__.py was initally written back in September :)

I believe that the last bug preventing logging of Product import and initialization exceptions was squashed in the 2.2.1 release; output of tracebacks was fixed.

Yeah, but what about all the other classes in the rs Product? They still have to have the icon property, and then it starts drift a bit: some classes their icon definition ?in themselves?, while this one (rs) doesn't. Correct? If so, I don't like that, and don't think I'll use it. Can't really see why it would be benefitial actually, I'm probably missing something here.

It is a simplification of the most common case; usually only registered classes appear in the ZMI and therefor need an icon. Indeed, if you have a Product that has classes that will also appear in the ZMI, but have no need to be registered (because they aren't user-addable?) then the old method may be easier to maintain for you. -- Martijn Pieters | Software Engineer mailto:mj@digicool.com | Digital Creations http://www.digicool.com/ | Creators of Zope http://www.zope.org/ ---------------------------------------------
