Re: Refresh dialog

[Phil Wolff <adiabat centurylink net>]

The code you posted is incomplete and does not compile. I suspect your 
problem is that you didn't call Gtk::ApplicationWindow::add ( vBox ). I 
did, and it shows the "Message" column title as you would expect. It 
does *not* display "hello" -- since the tree contains nothing that can 
be selected,  the iterator is undefined. Changing the test to 
"if(!iter)" causes "hello" to be displayed as well. See 
http://pastebin.com/EGsexKmW

If you post sample code in the future, please be sure that it will 
compile and link without errors.
