gnome_window_toplevel_set_title ()

void
gnome_window_toplevel_set_title (GtkWindow *window,
                                 const gchar *doc_name,
                                 const gchar *app_name,
                                 const gchar *extension);

Set the title of a toplevel window. This is done by appending the window-specific name (less the extension, if any) to the application name. So it appears as "<appname> : <docname>".

This parameters to this function are appopriate in that it identifies application windows as containing certain files that are being worked on at the time (for example, a word processor file, a spreadsheet or an image).
