check buttons in a clist

[Jim Parker <hopeye cfl rr com>]

G'Day !

I am developing an application in GTK 1.2.x

What I need to do is get a check button(s) in a variable length list in 
a dialog box.  At first glance it seems a clist is what I want, but 
after looking at the API, tutorial, and list archives, I'm not sure the 
clist can do what I need.

What is the best widget to use ?  any example code ?

For a better explanation of what I need:

I am developing a vector drawing program.  The program will support the 
use of layers to remove portions of the drawing, to avoid clutter.  The 
number of layers will be arbitrary.

I want a dialog so the user can select whick layers are visible.  Most 
similar programs use what appears to be a clist with check boxes 
embedded into the rows.

cheers,
