a) for wxACTION_LISTBOX_FIND it has the natural meaning: this is the string

b) for wxACTION_LISTBOX_SELECT and wxACTION_LISTBOX_EXTENDSEL it is used
to decide if the listbox should send the notification event (it is empty)
or not (it is not): this allows us to reuse the same action for when the
user is dragging the mouse when it has been released although in the
first case no notification is sent while in the second it is sent.
