Hi,
 

> m_adjustment.set_page_size((int)val);
The method set_page_size needs a double as parameter, see http://www.gtkmm.org/docs/gtkmm-2.4/docs/reference/html/classGtk_1_1Adjustment.html#8ce619f778049f760ef25269d9da7273

> m_adjustment.set_page_increment((int)val);
The method set_page_increment needs a double too, see http://www.gtkmm.org/docs/gtkmm-2.4/docs/reference/html/classGtk_1_1Adjustment.html#7cb297efb8bf3bb30aa51c754718f22a

> m_OptionMenu.set_menu(*m_pMenu);
The method needs a reference to Gtk::Menu, see http://www.gtkmm.org/docs/gtkmm-2.4/docs/reference/html/classGtk_1_1OptionMenu.html#0803d2e805dd785709c502374555a720

I can't test now the methods set_page_size and set_page_increment, but I remember that the set_menu(*m_pMenu) cannot compile.

Why do you think these are errors? Did you have a compilation error?
