+/*
+ * Some remarks about single/multi selection:
+ * A table in single selection mode has only one line/item selected which is equal to the
+ * current item (means the highlighted line). Asking for `CurrentItem in YCP looks for
+ * selectedItem() (see YCPPropertyHandler::tryGetSelectionWidgetValue).
+ * In multi selection mode there can be several items selected (here is means checked/marked
+ * with [x]) and the value is also got from selectedItem() when asking for `SelectedItems
+ * (see YCPPropertyHandler::tryGetSelectionWidgetValue).
+ * This means for multi selection mode: at the moment there isn't a possibility to get the
+ * `CurrentItem. To get the current item (which line of the list is currently highlighted),
+ * a virtual function currentItem() like available for the MultiSelectionBox has to be
+ * provided to allow NCTable to specify the line number itself (getCurrentItem).
+ *
