    //    option box is consistent with the layout of the rest of the
    //    application.

    //    ==============================

    //    necessary, but in some cases, for example, a button labelled
    //    'Create' may be more meaningful to the user than one labelled
    //    'Apply'.
    //
    //    Disable those buttons that are not applicable to the option box.
    //
    //    Attach actions to those buttons that are applicable to the option
    //    box.  Note that the 'Close' button has a default action attached
    //    to it that will hide the window.  If a a custom action is
    //    attached to the 'Close' button then be sure to call the 'hide the
    //    option box' procedure within the custom action so that the option
    //    box is hidden properly.

    //    'Apply' button.
    //

    button -edit
        -command ($setup + " " + $parent + " " + 1)

    //    Step 7: Set the option box title.
    //    =================================
    //
    setOptionBoxTitle("Display Layer Options");

    //    Step 8: Customize the 'Help' menu item text.
    //    ============================================
    //
    setOptionBoxHelpTag( "" );

    //    Step 9: Set the current values of the option box.
