Hi Julien


I've never done this myself but can't you listen to "checkchange"
events from the tree panel and do the following in the listener:

 - if the node is a layer node, and if that node and its siblings are
(un)checked, then (un)check the parent node
- if the node has layer nodes as its children, check/uncheck these
children nodes as appropriate

You can possibly implement this in a plugin, whose "init" method will
register the "checkchange" listener on the tree panel.

Hope it helps,
