zope.app.tree 3.5.1

What is ZopeTree?

ZopeTree is a port of Philipp’s Zope2 product ZopeTree. ZopeTree was meant to be a light-weight and easy-to-use static tree implementation, mainly designed for use in ZPTs. It was originally written because Zope2’s ZTUtils.Tree was found to be too complicated and inflexible.

The ZTUtils package has not been ported to Zope3. Parts of it, like batching, have found their way into Zope3, though. Only support for static tree generation is not in the core.

How to use it

Customization

The best way to customize ZopeTree is to define your own view for objects (usually ‘*’). If you want to use the cookie functionality, simply extend the cookie browser view:

from zope.app.tree.filters import OnlyInterfacesFilter
from zope.app.tree.browser.cookie import CookieTreeView

class BendableStaticTreeView(StaticTreeView):

    def bendablesTree(self):
        # tree with only IBendables, but also show the folder
        # they're in
        filter = OnlyInterfacesFilter(IBendable, IFolder)
        return self.cookieTree(filter)

You can also write your own filters. All you have to do is implement the IObjectFindFilter interface (which is trivial):

from zope.interface import implements
from zope.app.interfaces.find import IObjectFindFilter

class BendableFilter:
    implements(IObjectFindFilter)

    def matches(self, obj)
        # only allow bendable objects
        return obj.isBendable()

3.5.1 (2009-01-29)

• Add compatibility for newer zope.traversing releases that require us to explicitly set up testing. This also works with older releases.

3.5.0 (2009-01-17)

• Get rid of zope.app.zapi dependency, replacing its uses with direct imports.

• Clean up dependencies, move testing and rotterdam dependencies to extra requires.

• Fix mailing list address to zope-dev@zope.org instead of retired zope3-dev@zope.org. Change cheeseshop to pypi in the package url.

• Replace __used_for__ in adapters.py with zope.component.adapts calls to make more sense.

• Remove obsolete zpkg files, zcml include file for mkzopeinstance-based installations, versions.txt that makes no sense now.
