+	\class HbView
+	\brief HbView is a base class for all the views that can be set to HbMainWindow.
+	HbView is a QGraphicsWidget, which contains a title, an icon, a menu and
+	a tool bar for one view in HbMainWindow.
+	HbMainWindow will handle updating title, icon, menu and tool bar, when
+	the view is activated. Title is used in application's title pane area.
+	HbView handles the visibility of tool bar, though HbMainWindow will
+	reparent it when ever view comes active.
+	Example 1 for creating a simple view
+	\include view1/main.cpp
+	Example 2 for creating view with title, icon, menu, toolbar and a widget.
+	\include view2/main.cpp
