i was reading over the source for the range widget example and i was wonder why this was there
#ifndef GTKMM_DISABLE_DEPRECATED Gtk::OptionMenu m_OptionMenu; #endif //GTKMM_DISABLE_DEPRECATED why is it in ifndef? i looked up some stuff about it im guessing it means it is showing newer code for option menus and disabling old obselete code. and then another random thought i had was about signals. i wanted to make two buttons do different things when clicked but i dont know how to connect them to a on_button_clicked. can there be multiple on_button_clicked signals or only one and then you have to use a new signal. also thanks for the book murray.
