     The HbTreeViewItem class provides an item that is used by the HbTreeView class to
     visualize content within single model index. The item can only be used with HbTreeView
-    or with objects derived from HbTreeView. By default the HbTreeViewItem supports
-    all the same content that HbListViewItem supports. In addition to this it is able to 
-    visualize parent items.
+    or with objects derived from HbTreeView. 
+    
+    HbTreeViewItem supports following model item types in Hb::ItemTypeRole role of data model
+    \li Hb::StandardItem
+    \li Hb::ParentItem. Parent item visualizes collapsed/expanded state of parent item with "subitem-indicator" item.
+    \li Hb::SeparatorItem
+    HbAbstractViewItem documentation provides details how these item types distinguish from each other. 
+
+    HbTreeViewItem supports all the same data content in child items as HbListViewItem does. 
+    Parent item visualizes by default expanded/collapsed icon and content of "text-1" primitive item. This is defined in HbTreeViewItem WidgetML file.
+    Handling Qt::BackgroundRole item data role takes place in base class HbAbstractViewItem.
