[Zope] Catalog without a Z

[Andre Meyer]

Thanks for your help. With your help I have added a ZCatalog to my 
product and some indexes to it. Next question is how to add new items to 
the indexes as they are created and edited. CatalogAware alone does not 
seem to be sufficient.

Here is what I have so far:

------------------------------------------------------------------------

from Products.ZCatalog import ZCatalog
...
class MusicLibrary(Folder):
    "A Zope Folder for the objects of the Music Library"
   
    meta_type = "Music Library"
   
    def __init__(self, id, title, description = ""):
        ...      
        self._catalog = ZCatalog.*ZCatalog*('Catalog')
        self._catalog.*addIndex*('path_index', 'PathIndex')
        self._catalog.*addIndex*('text_index', 'TextIndex')
        self._catalog.*addIndex*('field_index', 'FieldIndex')
        self._*setObject*('Catalog', self._catalog)
    ...
    def addItem(self, id, item):
        self._*setObject*(id, item)
        self.category = None
       
        self._catalog.*catalog_object*(item) # does not work yet !!!

------------------------------------------------------------------------

from Products.ZCatalog.CatalogPathAwareness import CatalogAware
...
class Composer(SimpleItem, *CatalogAware*):
    ...

------------------------------------------------------------------------

Any ideas or examples? Your help is appreciated.

thanks
Andre
