  // Warn: Remeber about changing fonts. You CAN NOT have *different* fonts
  //       for the *same* item, depening on your wish. For example, the
  //       first time event is fired you set font for Item1 'Arial 10',
  //       and the next time you set font for the same Item1 'Arial 12'.
  //       Because height is calculated only once, and you may have
  //       problems with text painting (when you change font text can
  //       become too large and be cut or override another cell)
