Optimum way to set the width of a clist

[lightmanaj earthlink net]

Hi all,

The gtk+ tutorial suggests that we hard-code our column widths in 
a clist. However, what I want to do instead is to take the width of 
the longest row and use that as the width of the entire column. 
That way, the size of the clist won't be dependent upon the font or 
the theme that a user has configured. Is this possible?

Thanks,
