Re: Using Gtk::Builder with a doubly-derived widget

A subject line would be fine.

Do you intend to create a GtimerController widget from the gtimer.glade 
file? Something like

    GtimerController *gtimer = nullptr;
    refFileBuilder->get_widget_derived("m_main_window", gtimer);

I would try

GtimerController::GtimerController(BaseObjectType* cobject, const 
Glib::RefPtr<Gtk::Builder> &builder)
    : GtimerGui(cobject, builder)
    {
    }

I haven't tested anything like that, but I think it will work.
