Howdy,
Mohamed's answer was almost right. But I guess you may rather want to
use the "changeOpen" event, when a tree folder is actually opened, and
not just selected?
Something like:
myFolder.addEventListener("changeOpen", function(e) { /* do AJAX call */ });
Keep in mind that every property that has been added to a qooxdoo class
by addProperty() fires a corresponding event for every change of the
property value. That is quite a powerful feature that can be used here
for the property "open".
For more info on property events, please have a look at
http://qooxdoo.oss.schlund.de/documentation/event-system#link0
Bye,
Andreas

Hello,
it's simple, when a slectionchanged event occured on a node, you simply send an
XmlHttpRequest to the server, with the id of the node selected, you will call a
php file for example, who will fetch the information for the node, and then with
these information you can add subnodes to your node.
I hope that will help you.
Peace upon you.
