  ; - as setgadgetitemtext however does not scroll up or down
  ;
  ; listviewgadgets can scroll up / down when overwriting an entry (this is due to the behaviour of the
  ; gadget under windows, where an entry is replaced by first sending a delete message causing the scroll,
  ; followed by an insert item message)
