2788      * So instead we abandon the dialog's action area completely:
2789      * we gtk_widget_hide() it in the below code, and we also call
2790      * gtk_dialog_set_has_separator() to remove the separator above
2791      * it. We then insert our own action area into the end of the
2792      * dialog's main vbox, and add our own separator above that.
2793      *
2794      * (Ideally, if we were a native GTK app, we would use the
2795      * GtkHButtonBox's _own_ innate ability to support one set of
2796      * buttons being right-aligned and one left-aligned. But to do
2797      * that here, we would have to either (a) pick apart our cross-
2798      * platform layout structures and treat them specially for this
2799      * particular set of controls, which would be painful, or else
2800      * (b) develop a special and simpler cross-platform
2801      * representation for these particular controls, and introduce
2802      * special-case code into all the _other_ platforms to handle
2803      * it. Neither appeals. Therefore, I regretfully discard the
