I am trying to hook the 'clicked' signal of a button to a callaback function that receives a std::string value that will be displayed in a Dialogbox. I have tried this: callback function ~~~~~~~~~~~~~~~~~ gboolean MessageInfo(std::string& msg){...} g_signal_connect(GTK_OBJECT(btnCreateAccount), "clicked", GTK_SIGNAL_FUNC(MessageInfo), NULL); But this does not work, can anyone help?
