As a networking example it doesn't contribute much. But it has some
interesting uses of widget/events

-    \example googlesuggest
-    \title Google Suggest Example
-    \ingroup examples-network
-    \brief Obtains the list of search recommendations by the Google search engine.
-
-    The example uses the QNetworkAccessManager to obtain the list of search
-    recommendations by Google as the user types into a QLineEdit.
-
-    \image googlesuggest-example.png
-
-    The application makes use of the \c get function in
-    QNetworkAccessManager to post a request and obtain the result of the search
-    query sent to the Google search engine. The results returned are listed as
-    clickable links appearing below the search box as a drop-down menu.
-
-    The widget is built up by a QLineEdit as the search box, and a QTreeView
-    used as a popup menu below the search box.
-
-    \section1 GSuggestCompletion Class Declaration
-
-    This class implements an event filter and a number of functions to display
-    the search results and to determent when and how to perform the search.
-
-    \snippet googlesuggest/googlesuggest.h 1
-
-    The class connects to a QLineEdit and uses a QTreeWidget to display the
-    results. A QTimer controls the start of the network requests that are
-    executed using a QNetworkAccessManager.
-
-    \section1 GSuggestCompletion Class Implementation
-
-    We start by defining a constant containing the URL to be used in the Google
-    queries. This is the basis for the query. The letters typed into the search
-    box will be added to the query to perform the search itself.
-
-    \snippet googlesuggest/googlesuggest.cpp 1
-
-    In the constructor, we set the parent of this GSuggestCompletion instance
-    to be the QLineEdit passed in. For simplicity, the QLineEdit is also stored
-    in the explicit \c editor member variable.
-
-    We then create a QTreeWidget as a toplevel widget and configure the various
-    properties to give it the look of a popup widget. The widget is populated
-    with the results by Google Suggest API request.
-
-    Furthermore, we install the GSuggestCompletion instance as an event filter
-    on the QTreeWidget, and connect the \c itemClicked() signal with the \c
-    doneCompletion() slot.
-
-    A single-shot QTimer is used to start the request when the user has stopped
-    typing for 500 ms.
-
-    Finally, we connect the networkManagers \c finished() signal with the \c
-    handleNetworkData() slot to handle the incoming data.
-
-    \snippet googlesuggest/googlesuggest.cpp 2
-
-    Since the QTreeWidget popup has been instantiated as a toplevel widget, the
-    destructor has to delete it explicitly from memory to avoid a memory leak.
-
-    \snippet googlesuggest/googlesuggest.cpp 3
-
-    The event filter handles mouse press and key press events that are
-    delivered to the popup. For mouse press events we just hide the popup and
-    return focus to the editor widget, and then return true to prevent further
-    event processing.
-
-    Key event handling is implemented so that Enter and Return execute the
-    selected link, while the Escape key hides the popup. Since we want to be
-    able to navigate the list of suggestions using the different navigation
-    keys on the keyboard we let Qt continue regular event processing for those
-    by returning false from the eventFilter reimplementation.
-
-    For all other keys, the event will be passed on to the editor widget and the
-    popup is hidden. This way the user's typing will not be interrupted by the
-    popping up of the completion list.
-
-    \snippet googlesuggest/googlesuggest.cpp 4
-
-    The \c showCompletion() function populates the QTreeWidget with the results
-    returned from the query. It takes a QStringList of the suggested search
-    terms.
-
-    \snippet googlesuggest/googlesuggest.cpp 5
-
-    A QTreeWidgetItem is created for each index in the list and inserted into
-    the QTreeWidget. Finally, we adjust position and size of the popup to make
-    sure that it pops up in the correct position below the editor, and show it.
-
-    The \c doneCompletion() function, which is called by the event filter when
-    either Enter or Return keys are pressed, stops the timer to prevent further
-    requests and passes the text of the selected item to the editor. We then
-    make the \c editor QLineEdit emit the returnPressed() signal, to which the
-    application can connect to open the respective web page.
-
-    \snippet googlesuggest/googlesuggest.cpp 6
-
-    The \c autoSuggest() slot is called when the timer times out, and uses the
-    text in the editor to build the complete search query. The query is then
-    passed to the QNetworkAccessManager's \c get() function to start the
-    request.
-
-    \snippet googlesuggest/googlesuggest.cpp 7
-
-    The function \c preventSuggest() stops the timer to prevent further
-    requests from being started.
-
-    \snippet googlesuggest/googlesuggest.cpp 8
-
-    When the network request is finished, the QNetworkAccessManager delivers the
-    data received from the server through the networkReply object.
-
-    \snippet googlesuggest/googlesuggest.cpp 9
-
-    To extract the data from the reply we use the \c readAll() function, which
-    is inherited from QIODevice and returns a QByteArray. Since this data is
-    encoded in XML we can use a QXmlStreamReader to traverse the data and
-    extract the search result as QStrings, which we can stream into two
-    QStringLists used to populate the popup.
-
-    Finally, we schedule the QNetworkReply object for deletion using the \c
-    deleteLater function.
-
-    \section1 SearchBox Class Declaration
-
-    The SearchBox class inherits QLineEdit and adds the protected slot \c
-    doSearch().
-
-    A \c GSuggestCompletion member provides the SearchBox with the request
-    functionality and the suggestions returned from the Google search engine.
-
-    \snippet googlesuggest/searchbox.h 1
-
-    \section1 SearchBox Class Implementation
-
-    The search box constructor instantiates the GSuggestCompletion object and
-    connects the returnPressed() signal to the doSearch() slot.
-
-    \snippet googlesuggest/searchbox.cpp 1
-
-    The function \c doSearch() stops the completer from sending any further
-    queries to the search engine.
-
-    Further, the function extracts the selected search phrase and opens it
-    in the default web browser using QDesktopServices.
