Hello @sveins12, and thanks for your interest on the component. Well, rather the
widget.
As it is meant to be simple, it does not come all the inheritance path to such events. They are simply not wired up to the component, and I'm talking Ext JS level,
as you can see in the documentation (enable viewing inherited entities).
That is literally due to the fact it is not an
Ext.Component (in the classh hierarchy tree), but an
Ext.Widget, meant to be lightweight, simple, and not implement lots of the functionality its equivalent
Ext.tree.Panel does.
That said, anything you miss from the simple tree widget, you'll probably miss it because what you need is a full-fledged [b]TreePanel[b].
I hope this helps!
