How to load data into Ext.tree.TreePanel (not through ajax)

Question

in example here http://docs.sencha.com/ext-js/3-4/#!/api/Ext.tree.TreePanel

i can see property dataUrl: 'get-nodes.php',

but how i can change data from inside my code? there is no store property or setSource method

EDIT:

as i found, one of the possibilities is to create my own Ext.tree.TreeLoader that would have setSource method and use it instead of default

maybe there is more variants?

EDIT:

seems there is already a solution for this
