Well, if you pick up an event/signal from the same page it has the function
definition for it. For example:

void                user_function                      (GtkComboBox  *widget,
                                                        GtkScrollType scroll_type,
                                                        gpointer      user_data)        : Run Last / Action

I was kind of hoping to get something like this for this signal.

Also, do you know how do I make the function that connects to
this signal? I was hoping to write something like this:

void my_func( GtkComboBox *widget, GtkScrollType scroll_type, gpointer user_data)
{
     if( widget->popup-shown )
     {
// code for list shown
     }
     else
     {
// code for list not shown
     }
}

But I don't know if this is a right prototype or not.
And the code itself, I'm not sure if it's right as well, as I can't check...
