Dear CmaniaC

You might be interested this:

<listbox rows="1" mold="select" onSelect="alert(self.getSelectedItem().label)"
>
<listitem label="option1"/>
<listitem label="option2"/>
<listitem label="option3"/>
</listbox>

If I misunderstand your question, please inform me.

Thank you

What onChange events you want to fire?

Because Listbox seems has no text area for editing, so the most reasonable onChange events here should be add or remove.

I'm not try it myself, but you can take a look at :

Component::onChildAdded()
Component::onChildRemoved()

I think add listening action in *.zul to these two will works.

Dear CmaniaC

In additional, a client side javascript action can be assigned to it by "action"
attribute
Ex:
<listbox rows="1" mold="select" action="onchange:alert('test')" >
<listitem label="option1"/>
<listitem label="option2"/>
<listitem label="option3"/>
</listbox>

Or Developer Guide Page.155

If you use this CSA(client side action) approach, you will have to pass the value back to Server Manually.
Please check the ZK wiki
