I'm using Ext.list.Tree (xtype: 'treelist') component as a navigation tree for the app.

I am trying to catch when a user tries to select a different node and display a warning message before continuing. If a user chooses to stay on the page then I need to cancel the select event so the current tree node is still selected.

The problem is that this component doesn't seem to have beforeselect event or anything like that, similar to Ext.tree.View. Is there an easy way to manually add it without switching to tree view?

@ardabeyazoglu Added, just a standard tree. – serg Dec 29 '15 at 20:52
Why don't you use a treepanel instead of treelist? treepanel has all the listeners you want – Guilherme Lopes Feb 05 '16 at 18:07
