I'm trying to do that, but I can't reach it. This is my code:
dynamic_cast<Gtk::CellRendererToggle
*>(this->treeviewIntercettazioniRisultati->get_column_cell_renderer(10))->signal_toggled().connect(SigC::slot(*this,&window1::on_toggled),false);

where on_toggled is the callback function defined in window1 with the
widget treeviewIntercettazioniRisultati.

The error is on the line of the dynamic_cast and it is:
