Any pointer to docs and examples somewhere ?

Copy zpt_examples.zexp from Products/PageTemplates/examples/ to your import/ directory and import it. Among the sample code in it is an implementation of the ZMI Folder tree using TreeMaker. I wrote TreeMaker as a basic tool for dtml-tree-like operations, but never really polished or documented it once I had the fundamentals working. TreeMaker is meant to work as follows: 1. Create a TreeMaker instance. 2. Specify how your object tree is defined. For example, use setChildAccess to indicate that each of your objects has a 'kids' attribute that contains a list of children, and setIdAttr to indicate that each object's 'path' attribute should be used to identify it. 3. Pass your root object to the tree() method. The result is a tree of TreeNode objects. The 'expanded' argument of tree() controls how much of this tree is built. 4. Use the TreeNode's walk() method to apply a function to the tree, such as one that produces an HTML representation. The flat() method gives you a preorder list of the objects in the tree, which can be combined with encodeExpansion to save the state of the tree. SimpleTreeMaker adds a branch() method to nodes that makes it easier to generate a tree of link from a ZPT. Cheers, Evan @ 4-am
