It was on the gtk-list rather than the gtkmm-list :

Possibly I may have mistyped - I use "get_state", not "get_active".
I have an array of RadioButton instances, all attached to the same
callback function for signal_clicked, which looks like: 
void MyClass::ClickedCallBack ( unsigned int idx )
    if ( ModeButton[idx].get_state() )
        printf ( "Mode %d selected\n", idx );
        // Now in this mode
        // blah blah
        printf ( "Mode %d deselected\n", idx );
        // No longer in this mode
        // blah blah

The callback is attached with:
    for ( cc=0; cc<NumButtons; cc++ )
        ModeButton[cc].signal_clicked().connect ( sigc::bind<int> ( 
                     sigc::mem_fun(*this, &MyClass::ClickedCallBack), cc ) );

That works for me on GTKmm-2
