XmListSelectItem highlights and adds to the selected list the
first item in the list that matches item.
widget
Specifies the ID of the List widget from whose list an item is selected.
item
Specifies the item to be selected in the List widget.
If item appears more than once in the List, only the
first occurrence is matched.
notify
Specifies a Boolean value that when TRUE invokes the selection callback
for the current mode. From an application interface view, calling this
function with notify True is indistinguishable from a user-initiated
selection action.
When notify is FALSE, no callbacks are called.
