First of all, questions about gtk programming or gtk app programming belong in gtk-app-devel list. To answer your question. Glade-2 produces an interface.h file. In this file several *create functions are declared. E.g. create_window1(). This function creates obviously a window and returns it as a GtkWidget*. E.g: GtkWidget *myWindow = create_window1(); Make sure the widgets you want to reference are proper named via the glade-2 editor. I assume your entryStartNum has the name "entryStartNum" :-) Use lookup_widget as in the next example: GtkWidget *myEntry = lookup_widget(myWindow, "entryStartNum"); It's that simple. Btw, it may proof usefull to look at libglade2 where the glade files (which are xml files) are used to create your UI.
