def remove_selected_items
  # Take the selected items and call row on each to get an array of the item indexes
  # Sort that array because selectedItems is returned in the order selected, not numerical order
  # Reverse this array of indices so we remove the last item first,
  # this allows all the indexes to remain constant
  # Call takeItem of each of the indices and then dispose the resulting ListWidgetItem that is returned
  selectedItems.map {|x| row(x)}.sort.reverse.each { |index| takeItem(index).dispose }
