ListStore + glade

[MDK <demultiplexer7 freemail hu>]

Hello,

I am totally new to gtkmm so forgive me if I'm doing something seriously 
wrong. I designed a window with some comboboxes on it using glade. I 
filled the comboboxes in glade so I have liststores and cell renderers.
I can reach the widgets and liststores, my problem is that I don't know 
how to reach the  modelcolumn. I don't even know the name of the 
modelcolumn since I don't see it in glade(file). Any suggestions?

Daniel
