I have a concern about this approach. In fact I had to do certain 
different things like sort the clist on a left-mouse click and pop-up a 
menu on right-mouse click. The "click_column" signal is only emitted on 
a left-mouse.

So, here is what I have done...

* Connect my own signal handlers to the column title buttons
   
   GTK_CLIST(clist)->column[i].button

   to the signal "event"

   It looks like the following:
   gtk_signal_connect(GTK_OBJECT(GTK_CLIST(clist)->column[i].button),
                "event",GTK_SIGNAL_FUNC(colSigHandler),(gpointer)i);
   ( 'i' is the column number )

* No within my signal handler colSigHandler() I will receive all the 
signals associated with that button, like all button-clicks, enter, 
leave etc and I can filter them to do whatever I like.

This approach works for me (a bit dirty though)
