Ahh, thanks. I take it that 'list' should be '&list' in the internal
gtk_container_foreach().
The reason why I asked is that I was looking to trigger 'activate'
signal on all Entry widgets when I exit the dialog window. I can use
'changed' signal, but it seems a little strange to save on every
character edit. Though, computer is fast enough and won't make a
difference in my case.
