How I can do for each item in the Tree Control to have
events, like a click event or something like that.
So when the user choose a item in the Tree Control, I need to
show a panel with other options and the same with the other
items... the click event must show diferent options.
I believe you can also listen for the "itemClick" event on
the Tree instead of using the "change" event. You can read
for more details on the events and when they get dispatched. (Note:
you may need to click "Show Inherited Events" to see the "change"
and "itemClick" events.)
