 * An abstract list model specializes WAbstractItemModel for
 * one-dimensional lists (i.e. a model with 1 column and no children).
 *
 * It cannot be used directly but must be subclassed. Subclassed
 * models must at least reimplement rowCount() to return the number of
 * rows, and data() to return data.
