To which message is this a reply, if any?

I vaguely remember a message to which this might have been a reply, but
I may be misremembering - I don't see any message with
"GtkEditable::activate bug or feature?" in the subject (and your message
doesn't have a "Re:" in the subject).

I infer from the message that somebody *might* have been suggesting that
a GtkEditable that didn't have anything connected to "activate" should
change its behavior in some fashion, e.g. arranging that it call
"gtk_window_activate_default()" so that <Enter> would activate the
default button regardless of whether you're in e.g. a GtkEntry or not.

It *is* a bit of a pain to have to do this manually when creating a
dialog box....

(It's also a bit of a pain to have to catch "key_press_event" in a
dialog window:

  void
  dlg_set_cancel(GtkWidget *widget, GtkWidget *cancel_button)
  {
    gtk_signal_connect(GTK_OBJECT(widget), "key_press_event",
      GTK_SIGNAL_FUNC(dlg_key_press), cancel_button);
  }

and have the handler do

  static gint
  dlg_key_press (GtkWidget *widget, GdkEventKey *event, gpointer cancel_button)
  {
    g_return_val_if_fail (widget != NULL, FALSE);
    g_return_val_if_fail (event != NULL, FALSE);

    if (event->keyval == GDK_Escape) {
      gtk_widget_activate(GTK_WIDGET(cancel_button));
      return TRUE;
    }

    return FALSE;
  }

where "cancel_button" is a "Cancel" button in the dialog box, so that
dialog boxes can be dismissed by hitting <ESC>.)
