3353.0. "modifications in a list box" by TLSE01::SCHLUMBERGER (Marc SCHLUMBERGER, WS-VMS-Ultrix Conslt) Tue Sep 18 1990 09:44

    Developping an application for a large customer we are trying to
    present a record of more than 100 characters in a list box.
    
    We need to supply the following request:
    
    The customer may click an item record in the list box.
    We must slip it in simple text widgets to allow a modification
    on some part of the record. 
    After a validation pass they may be append and we may overwrite(if
    it is possible) the record selected in the listbox by the new one.
    
    Does someone could give us an example of who to keep the item position
    in the list box, overwrite and refresh the listbox.
    
    Thanks for yours answers.
    
    That's all for today.

    I can give you a few pointers.  You can use XtGetValues to
    get DwtNselectedItems and DwtNselectedItemsCount.  This gives
    you a **DwtCompString struct which contains DwtNselectedItemsCount 
    of entries.  They are in the order that they were added to the
    list box.  You could use this to get both theDwtCompString that's
    printed in the ListBox and the position.  You can use the position
    later in DwtListBoxDeletePos to remove the old entry.  Then use
    DwtListBoxAddItem, passing in the position, to add the new line
    back in.
    
    Hope that helps!
