Ha!  You're right and I'm wrong.  I wrote this code over a year ago and 
obviously I forgot what I did.  In order to detect a button press in a 
GtkTreeView, do this:

gtk_signal_connect (GTK_OBJECT(widget), "button_press_event", 
GTK_SIGNAL_FUNC(gtktreeviewbuttonpressed), 
(gpointer)UMAKEINT(GetWidID(), cmd));

Don't worry about the last param, that's just the user_data that's 
specific to our application.

Here is the code from our app that actually does the popup.  This code 
comes from the gCvs member of the CvsGui family.

void UCvsPopupMenu::DisplayPopupMenu(void* info)
{
   if (menu !=  UMENU_NULL)
   {
        GdkEventButton *event = (GdkEventButton *) info;
        int button, event_time;
        
        if (event)
        {
           button = event->button;
           event_time = event->time;
           // printf("UCvsPopupMenu::DisplayPopupMenu called with event\n");
        }
        else
        {
           button = 0;
           event_time = gtk_get_current_event_time ();
           // printf("UCvsPopupMenu::DisplayPopupMenu called without event\n");
        }
                        
   gtk_menu_popup (GTK_MENU (menu), NULL, NULL, NULL, NULL,
                                button, event_time);
   }
}
