It sounds like you want to install a cell_data_func() that sets
CellRenderer properties based on model data.  See

http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/regexxer/regexxer/src/filetree.cc?rev=1.39&content-type=text/vnd.viewcvs-markup

for an example.  FileTree::text_cell_data_func() sets the foreground
color of text cells based on model information.
