NAME
       XmListSetAddMode — A List function that sets add mode in the list
SYNOPSIS
       #include <Xm/List.h>
       void XmListSetAddMode(
       Widget widget,
       Boolean state);
DESCRIPTION
       XmListSetAddMode  allows  applications  control  over  Add  Mode in the
       extended selection model.  This function ensures that the mode it  sets
       is  compatible  with  the  selection policy (XmNselectionPolicy) of the
       widget. For example, it cannot put the widget into add  mode  when  the
       value of XmNselectionPolicy is XmBROWSE_SELECT.
       widget    Specifies the ID of the List widget
       state     Specifies  whether  to  activate  or deactivate Add Mode.  If
                 state is True, Add Mode is activated. If state is False,  Add
                 Mode is deactivated.
