gtk_box_pack_start(GTK_BOX(box), radioButton4, FALSE, FALSE, 3);
gtk_box_pack_start(GTK_BOX(box), radioButton5, FALSE, FALSE, 3);
//Connects GCallback function gtk_main_quit to "destroy" signal for "window"
g_signal_connect(G_OBJECT(window), "destroy", G_CALLBACK(gtk_main_quit), NULL);
gtk_container_add(GTK_CONTAINER(window), box);
gtk_widget_show_all(window);
gtk_main();
return 0;
}
Next: Handle "toggled" signal of RadioButton and determine the active selected RadioButton in group
