managing selections

["Adrian E. Feiguin" <adrian ifir ifir edu ar>]

 Hi, I'm working on a Sheet widget and I'd like it to be able to handle
selections in the same way as gtkentry does. The problem is that my data
is allocated in structures (say GtkSheetCell) and I don't know how to use
the standard gtkselection with them. Can anybody tell me if it is
possible, or I'd have to create an "special porpose" "gtksheetselection"
selection handler?
 Thank you in advance,
