Question

I have a tree panel and I would like to associate an action to the click on a leaf of this tree. I managed to associate one to each click on the tree elements but I not only to the leaves.

Here my code, I tried it with very simple functions : (menu is a view extending tree.Panel)

Ext.define('WSR.controller.MenuControl', {

    extend: 'Ext.app.Controller',

    views: [
        'Menu',
        'Browser'
    ],

    stores: [ 'UserStore' ],

    init: function() {

        this.control({
            'menu': {
                itemclick: this.onItemClicked
            }
        });
    },

    onItemClicked: function() {
        console.log('ItemClicked');
    }
});

Is there somebody to help me please ?

Try:

Ext.define('WSR.controller.MenuControl', {

extend: 'Ext.app.Controller',

views: [
    'Menu',
    'Browser'
],

refs:[
    {
        selector: 'Menu', //Suggest u to use a selector that is more "tightened" in case you have more trees of this type
        ref: 'mynicetree'
    }
],

stores: [ 'UserStore' ],

init: function() {

    this.control({
        'menu': {
            //I suggest u use selectionchange instead, itemclick won't work if the use navigate the tree nodes using keyboard, whereas selectionchange fit both
            selectionchange: this.loadStuff
        }
    });
},

loadStuff: function() {

    //Assuming you can only select one node at a time (typical use case)
    var myTreePanel = this.getMynicetree();
    var nodes = myTreePanel.getSelectionModel().selection();
    if(!Ext.isEmpty(nodes))
    {
        var selNode = nodes[0];
        if(selNode.get("leaf")) //Assuming your NodeInterface "leaf" property was assigned
        {
            //Its a leaf
        }

        //OR
        if(selNode.isLeaf())
        {
            //Its a leaf
        }

    }
}

});

HTH!
