You can't currently put widgets inside CList, despite what might
be implied by the docs. 

One approach to your problem is to implement your toggle buttons
yourself. (I don't think the standard toggle buttons look very
good in a list anyways). You can do this by catching button presses
on the CList and using them to toggle a pixmap.

For examples of this, see gnorpm, or, 

 eider/eider/modules/CheckList.py

in GNOME CVS. 

(http://cvs.gnome.org/lxr/source/eider/eider/modules/CheckList.py)

The latter is in python, but it should be pretty straightforward to
translate into C and does it very thoroughly, including responding to
theme changes properly, etc.
