PIGGYBACK_LISTBOX and PIGGYBACK_LBI class declarations
|
|
|
|
This listbox piggybacks onto an ADMIN_SELECTION, from which
|
|
it gets its items. The ADMIN_SELECTION object is thus
|
|
assumed to stay around for the life of this listbox and all
|
|
its listbox items. Moreover, the ADMIN_SELECTION is assumed
|
|
not to change during that time.
