Cut/Copy/Paste menu selections

[Darryl Luff <darryl snakegully nu>]

Hi all.

The widgets in my app already respond to Ctrl-C/Ctrl-V and the 
select/middle button paste etc with their default behaviour. But I've 
added a standard Edit menu, containing Cut, Copy, Paste and Delete 
entries. What code needs to be in the callbacks for these menu 
selections? Should I send the appropriate signals to the current 
widgets, or are there existing functions I can call to give the standard 
behaviour when someone uses the menu items?

Thanks.
