XmAddTabGroup — A function that adds a manager or a primitive widget to the list of tab groups

       This  function  is  obsolete  and  its   behavior   is   replaced   by   setting   XmNnavigationType   to
       XmEXCLUSIVE_TAB_GROUP.   When  the  keyboard is used to traverse through a widget hierarchy, primitive or
       manager widgets are grouped together into what are known as tabgroups. Any manager or  primitive  widget
       can  be  a tab group. Within a tab group, move the focus to the next widget in the tab group by using the
       arrow keys. To move to another tab group, use KNextField or KPrevField.

       Tab groups are ordinarily specified by  the  XmNnavigationType  resource.   XmAddTabGroup  is  called  to
       control  the  order of traversal of tab groups. The widget specified by tab_group is appended to the list
       of tab groups to be traversed, and the widget's XmNnavigationType is set to XmEXCLUSIVE_TAB_GROUP.

       tab_group Specifies the manager or primitive widget ID
