The GTK docs suggest: GtkWidget *toplevel = gtk_widget_get_toplevel (widget); if (gtk_widget_is_toplevel (toplevel)) { /* Perform action on toplevel. */ } get_toplevel will return the topmost widget you're inside, whether or not it's a window, thus the is_toplevel check. Yeah something is mis-named since the code above does a "get_toplevel()" then an immediate "is_toplevel()" (most likely, get_toplevel() should be called something else). link|edit|flag answered Feb 24 at 1:23 Havoc P 2,00818

Though gtk_widget_get_toplevel should work, you may also give a try to the code below. It should get the parent gtk window for the given widget and print it's title. GdkWindow *gtk_window = gtk_widget_get_parent_window(widget); GtkWindow *parent = NULL; gdk_window_get_user_data(gtk_window, (gpointer *)&parent); g_print("%s\n", gtk_window_get_title(parent)); hope this helps, regards link|edit|flag answered Feb 24 at 2:43 serge_gubenko 5,9511610

This takes a needless detour through low-level GDK gunge - better to stay with the GTK layer. Here you require the widget to be realized, and will likely have issues in GTK 3. – Havoc P Feb 24 at 2:49
