[Gambas-user] How to search for an item in a treeview

[M0E Lnx]

Sorry for not being too specifc.

I'm trying to allow the user to search for specific items (initially
listed in the treeview)

so First, I want to populate the treeview with a massive collection
(already done)
Need to offer a search feature (this needs to find stuff in the
treeview (you already did))
Need to display ONLY the results of the search in the treeview.

There will be a button that the user can hit to restore the treeview
to the original content (full list)
