     \brief A configurable stock chart for the NASDAQ-100.
     \image qtquick-demo-stocqt.png
 
-    \e{StocQt} demonstrates various QML and \l{Qt Quick} features such as
-    displaying custom components and downloading data from the internet.
+    The \e{StocQt} application presents a trend chart for the first stock in
+    the list of NASDAQ-100 stocks maintained by it. It allows the user to
+    choose another stock from the list, and fetches the required data for
+    the selected stock by sending an \c XMLHttpRequest to
+    http://finance.yahoo.com.
+
+    The application uses several custom types such as Button, CheckBox,
+    StockChart, StockInfo, StockView, and so on. These types are used to
+    present the stock data in a readable form and also let the user customize
+    the trend chart. For example, the user can choose to view the yearly,
+    monthly, or daily trends in the stock price.
+
+    The application uses the ObjectModel type to access the two visual data
+    models that it depends on.

+
+    The StockListView model is a static data model listing the
+    NASDAQ-100 stocks with basic information such as stockId, name, value,
+    change, and so on. This data model is used by the application if the
+    user wants to choose another stock from the list.
+
+    StockView is a complex data model that presents a trend chart for the
+    selected stock. It uses another custom type, StockChart, which presents
+    the graphical trend of the stock price using a Canvas. This data model
+    is used for most of the time during the lifetime of the application.

+
+    To understand the application better, browse through its code using
+    Qt Creator.
