Load specific icons in tree.Panel depending on node type

I am begining in Extjs and i would like to make a tree (with tree.Panel) which contents both file and folder. Moreover I would like to display specific icons for each type of node : a file must not have a folder child so the icon "create folder" which must only appear on folder nodes. I already have a tree with a boutton "delete" which exists for both types.

I presume I must listen for a event like "renderer" and ask for the type of my node and load the corresponding icon but I don't know how to do : the event comes from a different column that the tree column.

How can I get the node type (leaf:true/false) from the actionColumn which will content the icon?

Please elaborate your question. If it is related to getting the node type(leaf or not) all you have to do is to add a renderer function to your column as below

              {
                    text: 'View in Filters',
                    flex: 2,
                    renderer: function (value, metaData, record) {
                      if(record.data.leaf){
                           //Do your stuff 
                         }
                       else {
                          //Do something else.
                           }
                    }

Or if it is related to showing different icons for parent and children check this once
