Re: Refreshing a Treeview within a modeless dialog window: How?

[allen777 <Allen Saucier itt com>]

For those who care, I have learned:

1. DON'T  attempt to "update" a row in a treeview through ANOTHER THREAD
that is OUTSIDE
     the main gtkmm gui thread.
2. If update a row's value while IN THE MAIN gui THREAD, it works just fine
setting the
     row to a new value - updates automatically.

More notes to come....
