In the _class_init of your widget, you'll have to add code like:

GtkBindingSet *binding_set;

binding_set = gtk_binding_set_by_class (klass);
gtk_binding_entry_add_signal (binding_set, GDK_Return, 0,
                              "show-help", 1,
                              GTK_TYPE_WIDGET_HELP_TYPE,
                              GTK_WIDGET_HELP_TOOLTIP);
gtk_binding_entry_add_signal (binding_set, GDK_KP_Enter, 0,
                              "show-help", 1,
                              GTK_TYPE_WIDGET_HELP_TYPE,
                              GTK_WIDGET_HELP_TOOLTIP);

You can probably also manually enforce displaying the tooltip using:

g_signal_emit_by_name (foo_widget, "show-help",
                       GTK_WIDGET_HELP_TOOLTIP);
