  59 A checklistbox is like a Listbox, but allows items to be checked or unchecked rather
  60 than relying on extended selection (e.g. shift-select) to select multiple items in
  61 the list.
  62
  63 This class is currently implemented under Windows and GTK.
  64
  65 This demo shows the basic CheckListBox and how to use the SetString method to change
  66 labels dynamically.
