I hope this is in the right group:  
I’m learning my way through Ruby-Gnome2 right now and am working on a  
simple program. All that it is going to do is let the user select a  
number from one combo box and another number from a different combo  
box and display the sum.

The question(s) I have is a)What widget (I think is the right term) do  
I need to use to display the sum? and b)How do I know which signals I  
am supposed to use?

Thanks
