Move the addressbook tutorial into manual tests

The tutorial is building an elaborate UI around a QMap. It doesn't use
structured data, and it doesn't use model/view (which the dedicated
addressbook example in itemviews does).

It's not a good way of building an application, and the individual APIs
for creating layouts, dialogs, or import/export are explained well
enough in other examples.

Pick-to: 6.5

-    It doesn't cover everything; the emphasis is on teaching the programming
-    philosophy of GUI programming, and Qt's features are introduced as needed.
-    Some commonly used features are never used in this tutorial.
-    \endomit

-    In this tutorial, you will learn about some of the basic
-    components of Qt, including:
-

-    \li Widgets and layout managers
-    \li Container classes
-    \li Signals and slots

-    \title Part 1 - Designing the User Interface
-    \brief Describes how to code the user interface of the Address Book Example.
-    This first part covers the design of the basic graphical user
-    interface (GUI) for our address book application.
-
-    The first step in creating a GUI program is to design the user
-    interface.  Here the our goal is to set up the labels and input
-    fields to implement a basic address book. The figure below is a
-    screenshot of the expected output.
-
-    \image addressbook-tutorial-part1-screenshot.png
-
-    We require two QLabel objects, \c nameLabel and \c addressLabel, as well
-    as two input fields, a QLineEdit object, \c nameLine, and a QTextEdit
-    object, \c addressText, to enable the user to enter a contact's name and
-    address. The widgets used and their positions are shown in the figure
-    below.
-
-    \image addressbook-tutorial-part1-labeled-screenshot.png
-
-    There are three files used to implement this address book:
-
-    \list
-        \li \c{addressbook.h} - the definition file for the \c AddressBook
-            class,
-        \li \c{addressbook.cpp} - the implementation file for the
-            \c AddressBook class, and
-        \li \c{main.cpp} - the file containing a \c main() function, with
-            an instance of \c AddressBook.
-    \endlist
-
-    \section1 Qt Programming - Subclassing
-
-    When writing Qt programs, we usually subclass Qt objects to add
-    functionality. This is one of the essential concepts behind creating
-    custom widgets or collections of standard widgets. Subclassing to
-    extend or change the behavior of a widget has the following advantages:
-
-    \list
-    \li We can write implementations of virtual or pure virtual functions to
-    obtain exactly what we need, falling back on the base class's implementation
-    when necessary.
-    \li It allows us to encapsulate parts of the user interface within a class,
-    so that the other parts of the application don't need to know about the
-    individual widgets in the user interface.
-    \li The subclass can be used to create multiple custom widgets in the same
-    application or library, and the code for the subclass can be reused in other
-    projects.
-    \endlist
-
-    Since Qt does not provide a specific address book widget, we subclass a
-    standard Qt widget class and add features to it. The \c AddressBook class
-    we create in this tutorial can be reused in situations where a basic address
-    book widget is needed.
-
-    \section1 Defining the AddressBook Class
-
-    The \c{tutorials/addressbook/part1/addressbook.h} file is
-    used to define the \c AddressBook class.
-
-    We start by defining \c AddressBook as a QWidget subclass and declaring
-    a constructor. We also use the Q_OBJECT macro to indicate that the class
-    uses internationalization and Qt's signals and slots features, even
-    if we do not use all of these features at this stage.
-
-    \snippet tutorials/addressbook/part1/addressbook.h class definition
-
-    The class holds declarations of \c nameLine and \c addressText,
-    the private instances of QLineEdit and QTextEdit mentioned
-    earlier.  The data stored in \c nameLine and \c addressText will
-    be needed for many of the address book functions.
-
-    We don't include declarations of the QLabel objects we will use
-    because we will not need to reference them once they have been
-    created.  The way Qt tracks the ownership of objects is explained
-    in the next section.
-
-    The Q_OBJECT macro itself implements some of the more advanced features of Qt.
-    For now, it is useful to think of the Q_OBJECT macro as a shortcut which allows
-    us to use the \l{QObject::}{tr()} and \l{QObject::}{connect()} functions.
-
-    We have now completed the \c addressbook.h file and we move on to
-    implement the corresponding \c addressbook.cpp file.
-
-    \section1 Implementing the AddressBook Class
-
-    The constructor of \c AddressBook accepts a QWidget parameter, \a parent.
-    By convention, we pass this parameter to the base class's constructor.
-    This concept of ownership, where a parent can have one or more children,
-    is useful for grouping widgets in Qt. For example, if you delete a parent,
-    all of its children will be deleted as well.
-
-    \snippet tutorials/addressbook/part1/addressbook.cpp constructor and input fields
-
-    In this constructor, the QLabel objects \c nameLabel and \c
-    addressLabel are instantiated, as well as \c nameLine and \c
-    addressText. The \l{QObject::tr()}{tr()} function returns a
-    translated version of the string, if there is one
-    available. Otherwise it returns the string itself. This function
-    marks its QString parameter as one that should be translated into
-    other languages. It should be used wherever a translatable string
-    appears.
-
-    When programming with Qt, it is useful to know how layouts work.
-    Qt provides three main layout classes: QHBoxLayout, QVBoxLayout
-    and QGridLayout to handle the positioning of widgets.
-
-    \image addressbook-tutorial-part1-labeled-layout.png
-
-    We use a QGridLayout to position our labels and input fields in a
-    structured manner. QGridLayout divides the available space into a grid and
-    places widgets in the cells we specify with row and column numbers. The
-    diagram above shows the layout cells and the position of our widgets, and
-    we specify this arrangement using the following code:
-
-    \snippet tutorials/addressbook/part1/addressbook.cpp layout
-
-    Notice that \c addressLabel is positioned using Qt::AlignTop as an
-    additional argument. This is to make sure it is not vertically centered in
-    cell (1,0). For a basic overview on Qt Layouts, refer to the
-    \l{Layout Management} documentation.
-
-    In order to install the layout object onto the widget, we have to invoke
-    the widget's \l{QWidget::setLayout()}{setLayout()} function:
-
-    \snippet tutorials/addressbook/part1/addressbook.cpp setting the layout
-
-    Lastly, we set the widget's title to "Simple Address Book".
-
-    \section1 Running the Application
-
-    A separate file, \c main.cpp, is used for the \c main() function. Within
-    this function, we instantiate a QApplication object, \c app. QApplication
-    is responsible for various application-wide resources, such as the default
-    font and cursor, and for running an event loop. Hence, there is always one
-    QApplication object in every GUI application using Qt.
-
-    \snippet tutorials/addressbook/part1/main.cpp main function
-
-    We construct a new \c AddressBook widget on the stack and invoke
-    its \l{QWidget::show()}{show()} function to display it.
-    However, the widget will not be shown until the application's event loop
-    is started. We start the event loop by calling the application's
-    \l{QApplication::}{exec()} function; the result returned by this function
-    is used as the return value from the \c main() function. At this point,
-    it becomes apparent why we instantiated \c AddressBook on the stack: It
-    will now go out of scope. Therefore, \c AddressBook and all its child widgets
-    will be deleted, thus preventing memory leaks.

-    \title Part 2 - Adding Addresses
-    \brief Describes the code for inserting records in the Address Book Example.
-
-    The next step in creating the address book is to implement some
-    user interactions.
-
-    \image addressbook-tutorial-part2-add-contact.png
-
-    We will provide a push button that the user can click to add a new contact.
-    Also, some form of data structure is needed to store these contacts in an
-    organized way.
-
-    \section1 Defining the AddressBook Class
-
-    Now that we have the labels and input fields set up, we add push buttons to
-    complete the process of adding a contact. This means that our
-    \c addressbook.h file now has three QPushButton objects declared and three
-    corresponding public slots.
-
-    \snippet tutorials/addressbook/part2/addressbook.h slots
-
-    A slot is a function that responds to a particular signal. We will discuss
-    this concept in further detail when implementing the \c AddressBook class.
-    However, for an overview of Qt's signals and slots concept, you can refer
-    to the \l{Signals and Slots} document.
-
-    Three QPushButton objects (\c addButton, \c submitButton, and
-    \c cancelButton) are now included in our private variable declarations,
-    along with \c nameLine and \c addressText.
-
-    \snippet tutorials/addressbook/part2/addressbook.h pushbutton declaration
-
-    We need a container to store our address book contacts, so that we can
-    traverse and display them. A QMap object, \c contacts, is used for this
-    purpose as it holds a key-value pair: the contact's name as the \e key,
-    and the contact's address as the \e{value}.
-
-    \snippet tutorials/addressbook/part2/addressbook.h remaining private variables
-
-    We also declare two private QString objects, \c oldName and \c oldAddress.
-    These objects are needed to hold the name and address of the contact that
-    was last displayed, before the user clicked \uicontrol Add. So, when the user clicks
-    \uicontrol Cancel, we can revert to displaying the details of the last contact.
-
-    \section1 Implementing the AddressBook Class
-
-    Within the constructor of \c AddressBook, we set the \c nameLine and
-    \c addressText to read-only, so that we can only display but not edit
-    existing contact details.
-
-    \dots
-    \snippet tutorials/addressbook/part2/addressbook.cpp setting readonly 1
-    \dots
-    \snippet tutorials/addressbook/part2/addressbook.cpp setting readonly 2
-
-    Then, we instantiate our push buttons: \c addButton, \c submitButton, and
-    \c cancelButton.
-
-    \snippet tutorials/addressbook/part2/addressbook.cpp pushbutton declaration
-
-    The \c addButton is displayed by invoking the \l{QPushButton::show()}
-    {show()} function, while the \c submitButton and \c cancelButton are
-    hidden by invoking \l{QPushButton::hide()}{hide()}. These two push
-    buttons will only be displayed when the user clicks \uicontrol Add and this is
-    handled by the \c addContact() function discussed below.
-
-    \snippet tutorials/addressbook/part2/addressbook.cpp connecting signals and slots
-
-    We connect the push buttons' \l{QPushButton::clicked()}{clicked()} signal
-    to their respective slots. The figure below illustrates this.
-
-    \image addressbook-tutorial-part2-signals-and-slots.png
-
-    Next, we arrange our push buttons neatly to the right of our address book
-    widget, using a QVBoxLayout to line them up vertically.
-
-    \snippet tutorials/addressbook/part2/addressbook.cpp vertical layout
-
-    The \l{QBoxLayout::addStretch()}{addStretch()} function is used to ensure
-    the push buttons are not evenly spaced, but arranged closer to the top of
-    the widget. The figure below shows the difference between using
-    \l{QBoxLayout::addStretch()}{addStretch()} and not using it.
-
-    \image addressbook-tutorial-part2-stretch-effects.png
-
-    We then add \c buttonLayout1 to \c mainLayout, using
-    \l{QGridLayout::addLayout()}{addLayout()}. This gives us nested layouts
-    as \c buttonLayout1 is now a child of \c mainLayout.
-
-    \snippet tutorials/addressbook/part2/addressbook.cpp grid layout
-
-    Our layout coordinates now look like this:
-
-    \image addressbook-tutorial-part2-labeled-layout.png
-
-    In the \c addContact() function, we store the last displayed contact
-    details in \c oldName and \c oldAddress. Then we clear these input
-    fields and turn off the read-only mode. The focus is set on \c nameLine
-    and we display \c submitButton and \c cancelButton.
-
-    \snippet tutorials/addressbook/part2/addressbook.cpp addContact
-
-    The \c submitContact() function can be divided into three parts:
-
-    \list 1
-    \li We extract the contact's details from \c nameLine and \c addressText
-    and store them in QString objects. We also validate to make sure that the
-    user did not click \uicontrol Submit with empty input fields; otherwise, a
-    QMessageBox is displayed to remind the user for a name and address.
-
-    \snippet tutorials/addressbook/part2/addressbook.cpp submitContact part1
-
-    \li We then proceed to check if the contact already exists. If it does not
-    exist, we add the contact to \c contacts and we display a QMessageBox to
-    inform the user that the contact has been added.
-
-    \snippet tutorials/addressbook/part2/addressbook.cpp submitContact part2
-
-    If the contact already exists, again, we display a QMessageBox to inform
-    the user about this, preventing the user from adding duplicate contacts.
-    Our \c contacts object is based on key-value pairs of name and address,
-    hence, we want to ensure that \e key is unique.
-
-    \li Once we have handled both cases mentioned above, we restore the push
-    buttons to their normal state with the following code:
-
-    \snippet tutorials/addressbook/part2/addressbook.cpp submitContact part3
-
-    \endlist
-
-    The screenshot below shows the QMessageBox object we use to display
-    information messages to the user.
-
-    \image addressbook-tutorial-part2-add-successful.png
-
-    The \c cancel() function restores the last displayed contact details and
-    enables \c addButton, as well as hides \c submitButton and
-    \c cancelButton.
-
-    \snippet tutorials/addressbook/part2/addressbook.cpp cancel
-
-    The general idea behind adding a contact is to give the user the
-    flexibility to click \uicontrol Submit or \uicontrol Cancel at any time. The flowchart below
-    further explains this concept:

-/*!
-    \example tutorials/addressbook/part3
-    \title Part 3 - Navigating between Entries
-    \brief Explains the code that enables navigating the contacts.
-
-    The address book is now about half complete. We should add the
-    capability to navigate the contacts, but first we must
-    decide what sort of a data structure we need for containing these
-    contacts.
-
-    In the previous section, we used a QMap of key-value pairs with
-    the contact's name as the \e key, and the contact's address as the
-    \e value. This works well for our case. However, in order to
-    navigate and display each entry, a little bit of enhancement is
-    needed.
-
-    We enhance the QMap by making it replicate a data structure similar to a
-    circularly-linked list, where all elements are connected, including the
-    first element and the last element. The figure below illustrates this data
-    structure.
-
-    \image addressbook-tutorial-part3-linkedlist.png
-
-    \section1 Defining the AddressBook Class
-
-    To add navigation functions to the address book, we must add two
-    more slots to the \c AddressBook class: \c next() and \c
-    previous() to the \c addressbook.h file:
-
-    \snippet tutorials/addressbook/part3/addressbook.h navigation functions
-
-    We also require another two QPushButton objects, so we declare \c nextButton
-    and \c previousButton as private variables:
-
-    \snippet tutorials/addressbook/part3/addressbook.h navigation pushbuttons
-
-    \section1 Implementing the AddressBook Class
-
-    In the \c AddressBook constructor in \c addressbook.cpp, we instantiate
-    \c nextButton and \c previousButton and disable them by default. This is
-    because navigation is only enabled when there is more than one contact
-    in the address book.
-
-    \snippet tutorials/addressbook/part3/addressbook.cpp navigation pushbuttons
-
-    We then connect these push buttons to their respective slots:
-
-    \snippet tutorials/addressbook/part3/addressbook.cpp connecting navigation signals
-
-    The image below is the expected graphical user interface.
-
-    \image addressbook-tutorial-part3-screenshot.png
-
-    We follow basic conventions for \c next() and \c previous() functions by
-    placing the \c nextButton on the right and the \c previousButton on the
-    left. In order to achieve this intuitive layout, we use QHBoxLayout to
-    place the widgets side-by-side:
-
-    \snippet tutorials/addressbook/part3/addressbook.cpp navigation layout
-
-    The QHBoxLayout object, \c buttonLayout2, is then added to \c mainLayout.
-
-    \snippet tutorials/addressbook/part3/addressbook.cpp adding navigation layout
-
-    The figure below shows the coordinates of the widgets in \c mainLayout.
-    \image addressbook-tutorial-part3-labeled-layout.png
-
-    Within our \c addContact() function, we have to disable these buttons so
-    that the user does not attempt to navigate while adding a contact.
-
-    \snippet tutorials/addressbook/part3/addressbook.cpp disabling navigation
-
-    Also, in our \c submitContact() function, we enable the navigation
-    buttons, \c nextButton and \c previousButton, depending on the size
-    of \c contacts. As mentioned earlier, navigation is only enabled when
-    there is more than one contact in the address book. The following lines
-    of code demonstrates how to do this:
-
-    \snippet tutorials/addressbook/part3/addressbook.cpp enabling navigation
-
-    We also include these lines of code in the \c cancel() function.
-
-    Recall that we intend to emulate a circularly-linked list with our QMap
-    object, \c contacts. So, in the \c next() function, we obtain an iterator
-    for \c contacts and then:
-
-    \list
-        \li If the iterator is not at the end of \c contacts, we increment it
-        by one.
-        \li If the iterator is at the end of \c contacts, we move it to the
-        beginning of \c contacts. This gives us the illusion that our QMap is
-        working like a circularly-linked list.
-    \endlist
-
-    \snippet tutorials/addressbook/part3/addressbook.cpp next() function
-
-    Once we have iterated to the correct object in \c contacts, we display
-    its contents on \c nameLine and \c addressText.
-
-    Similarly, for the \c previous() function, we obtain an iterator for
-    \c contacts and then:
-
-    \list
-        \li If the iterator is at the end of \c contacts, we clear the
-        display and return.
-        \li If the iterator is at the beginning of \c contacts, we move it to
-        the end.
-        \li We then decrement the iterator by one.
-    \endlist
-
-    \snippet tutorials/addressbook/part3/addressbook.cpp previous() function
-
-    Again, we display the contents of the current object in \c contacts.

-    \title Part 4 - Editing and Removing Addresses
-    \brief Explains how to add edit and remove functionality.
-
-    Now we look at ways to modify the contents of contacts stored in
-    the address book.
-
-    \image addressbook-tutorial-screenshot.png
-
-    We now have an address book that not only holds contacts in an
-    organized manner, but also allows navigation. It would be
-    convenient to include edit and remove functions so that a
-    contact's details can be changed when needed. However, this
-    requires a little improvement, in the form of enums. We defined
-    two modes: \c{AddingMode} and \c{NavigationMode}, but they were
-    not defined as enum values. Instead, we enabled and disabled the
-    corresponding buttons manually, resulting in multiple lines of
-    repeated code.
-
-    Here we define the \c Mode enum with three different values:
-
-    \list
-        \li \c{NavigationMode},
-        \li \c{AddingMode}, and
-        \li \c{EditingMode}.
-    \endlist
-
-    \section1 Defining the AddressBook Class
-
-    The \c addressbook.h file is updated to contain the \c Mode enum:
-
-    \snippet tutorials/addressbook/part4/addressbook.h Mode enum
-
-    We also add two new slots, \c editContact() and \c removeContact(), to
-    our current list of public slots.
-
-    \snippet tutorials/addressbook/part4/addressbook.h edit and remove slots
-
-    In order to switch between modes, we introduce the \c updateInterface() function
-    to control the enabling and disabling of all QPushButton objects. We also
-    add two new push buttons, \c editButton and \c removeButton, for the edit
-    and remove functions mentioned earlier.
-
-    \snippet tutorials/addressbook/part4/addressbook.h updateInterface() declaration
-    \dots
-    \snippet tutorials/addressbook/part4/addressbook.h buttons declaration
-    \dots
-    \snippet tutorials/addressbook/part4/addressbook.h mode declaration
-
-    Lastly, we declare \c currentMode to keep track of the enum's current mode.
-
-    \section1 Implementing the AddressBook Class
-
-    We now implement the mode-changing features of the address
-    book. The \c editButton and \c removeButton are instantiated and
-    disabled by default. The address book starts with zero contacts
-    in memory.
-
-    \snippet tutorials/addressbook/part4/addressbook.cpp edit and remove buttons
-
-    These buttons are then connected to their respective slots, \c editContact()
-    and \c removeContact(), and we add them to \c buttonLayout1.
-
-    \snippet tutorials/addressbook/part4/addressbook.cpp connecting edit and remove
-    \dots
-    \snippet tutorials/addressbook/part4/addressbook.cpp adding edit and remove to the layout
-
-    The \c editContact() function stores the contact's old details in
-    \c oldName and \c oldAddress, before switching the mode to \c EditingMode.
-    In this mode, the \c submitButton and \c cancelButton are both enabled,
-    hence, the user can change the contact's details and click either button.
-
-    \snippet tutorials/addressbook/part4/addressbook.cpp editContact() function
-
-    The \c submitContact() function has been divided in two with an \c{if-else}
-    statement. We check \c currentMode to see if it's in \c AddingMode. If it is,

-    \snippet tutorials/addressbook/part4/addressbook.cpp submitContact() function part1
-
-    Otherwise, we check to see if \c currentMode is in \c EditingMode. If it
-    is, we compare \c oldName with \c name. If the name has changed, we remove
-    the old contact from \c contacts and insert the newly updated contact.
-
-    \snippet tutorials/addressbook/part4/addressbook.cpp submitContact() function part2
-
-    If only the address has changed (i.e., \c oldAddress is not the same as \c address),
-    we update the contact's address. Lastly, we set \c currentMode to
-    \c NavigationMode. This is an important step as it re-enables all the
-    disabled push buttons.
-
-    To remove a contact from the address book, we implement the
-    \c removeContact() function. This function checks to see if the contact
-    exists in \c contacts.
-
-    \snippet tutorials/addressbook/part4/addressbook.cpp removeContact() function
-
-    If it does, we display a QMessageBox, to confirm the removal with the
-    user. Once the user has confirmed, we call \c previous() to ensure that the
-    user interface shows another contact, and we remove the contact using \l{QMap}'s
-    \l{QMap::remove()}{remove()} function. As a courtesy, we display a QMessageBox
-    to inform the user. Both the message boxes used in this function are shown below:
-
-    \image addressbook-tutorial-part4-remove.png
-
-    \section2 Updating the User Interface
-
-    We mentioned the \c updateInterface() function earlier as a means to
-    enable and disable the push buttons depending on the current mode.
-    The function updates the current mode according to the \c mode argument
-    passed to it, assigning it to \c currentMode before checking its value.
-
-    Each of the push buttons is then enabled or disabled, depending on the
-    current mode. The code for \c AddingMode and \c EditingMode is shown below:
-
-    \snippet tutorials/addressbook/part4/addressbook.cpp update interface() part 1
-
-    For \c NavigationMode, however, we include conditions within the parameters
-    of the QPushButton::setEnabled() function. This is to ensure that
-    \c editButton and \c removeButton are enabled when there is at least one
-    contact in the address book; \c nextButton and \c previousButton are only
-    enabled when there is more than one contact in the address book.
-
-    \snippet tutorials/addressbook/part4/addressbook.cpp update interface() part 2
-
-    By setting the mode and updating the user interface in the same
-    function, we avoid the possibility of the user interface getting
-    out of sync with the internal state of the application.

-    \example tutorials/addressbook/part5
-    \title Part 5 - Adding a Find Function
-    \brief Describes how to add a find function.
-
-    Here we look at ways to locate contacts and addresses in the
-    address book.
-
-    \image addressbook-tutorial-part5-screenshot.png
-
-    As we add contacts to our address book, it becomes tedious to
-    navigate the list with the \e Next and \e Previous buttons. A \e
-    Find function would be more efficient.  The screenshot above shows
-    the \e Find button and its position on the panel of buttons.
-
-    When the user clicks on the \e Find button, it is useful to
-    display a dialog that prompts for a contact's name. Qt provides
-    QDialog, which we subclass here to implement a \c FindDialog
-    class.
-
-    \section1 Defining the FindDialog Class
-
-    \image addressbook-tutorial-part5-finddialog.png
-
-    In order to subclass QDialog, we first include the header for QDialog in
-    the \c finddialog.h file. Also, we use forward declaration to declare
-    QLineEdit and QPushButton since we will be using those widgets in our
-    dialog class.
-
-    As in our \c AddressBook class, the \c FindDialog class includes
-    the Q_OBJECT macro and its constructor is defined to accept a parent
-    QWidget, even though the dialog will be opened as a separate window.
-
-    \snippet tutorials/addressbook/part5/finddialog.h FindDialog header
-
-    We define a public function, \c getFindText(), to be used by classes that
-    instantiate \c FindDialog. This function allows these classes to obtain the
-    search string entered by the user. A public slot, \c findClicked(), is also
-    defined to handle the search string when the user clicks the \uicontrol Find
-    button.
-
-    Lastly, we define the private variables, \c findButton, \c lineEdit
-    and \c findText, corresponding to the \uicontrol Find button, the line edit
-    into which the user types the search string, and an internal string
-    used to store the search string for later use.
-
-    \section1 Implementing the FindDialog Class
-
-    Within the constructor of \c FindDialog, we set up the private variables,
-    \c lineEdit, \c findButton and \c findText. We use a QHBoxLayout to
-    position the widgets.
-
-    \snippet tutorials/addressbook/part5/finddialog.cpp constructor
-
-    We set the layout and window title, as well as connect the signals to their
-    respective slots. Notice that \c{findButton}'s \l{QPushButton::clicked()}
-    {clicked()} signal is connected to \c findClicked() and
-    \l{QDialog::accept()}{accept()}. The \l{QDialog::accept()}{accept()} slot
-    provided by QDialog hides the dialog and sets the result code to
-    \l{QDialog::}{Accepted}. We use this function to help \c{AddressBook}'s
-    \c findContact() function know when the \c FindDialog object has been
-    closed. We will explain this logic in further detail when discussing the
-    \c findContact() function.
-
-    \image addressbook-tutorial-part5-signals-and-slots.png
-
-    In \c findClicked(), we validate \c lineEdit to ensure that the user
-    did not click the \uicontrol Find button without entering a contact's name. Then, we set
-    \c findText to the search string, extracted from \c lineEdit. After that,
-    we clear the contents of \c lineEdit and hide the dialog.
-
-    \snippet tutorials/addressbook/part5/finddialog.cpp findClicked() function
-
-    The \c findText variable has a public getter function, \c getFindText(),
-    associated with it. Since we only ever set \c findText directly in both the
-    constructor and in the \c findClicked() function, we do not create a
-    setter function to accompany \c getFindText().
-    Because \c getFindText() is public, classes instantiating and using
-    \c FindDialog can always access the search string that the user has
-    entered and accepted.
-
-    \snippet tutorials/addressbook/part5/finddialog.cpp getFindText() function
-
-    \section1 Defining the AddressBook Class
-
-    To ensure we can use \c FindDialog from within our \c AddressBook class, we
-    include \c finddialog.h in the \c addressbook.h file.
-
-    \snippet tutorials/addressbook/part5/addressbook.h include finddialog's header
-
-    So far, all our address book features have a QPushButton and a
-    corresponding slot. Similarly, for the \uicontrol Find feature we have
-    \c findButton and \c findContact().
-
-    The \c findButton is declared as a private variable and the
-    \c findContact() function is declared as a public slot.
-
-    \snippet tutorials/addressbook/part5/addressbook.h findContact() declaration
-    \dots
-    \snippet tutorials/addressbook/part5/addressbook.h findButton declaration
-
-    Lastly, we declare the private variable, \c dialog, which we will use to
-    refer to an instance of \c FindDialog.
-
-    \snippet tutorials/addressbook/part5/addressbook.h FindDialog declaration
-
-    Once we have instantiated a dialog, we will want to use it more than once;
-    using a private variable allows us to refer to it from more than one place
-    in the class.
-
-    \section1 Implementing the AddressBook Class
-
-    Within the \c AddressBook class's constructor, we instantiate our private
-    objects, \c findButton and \c findDialog:
-
-    \snippet tutorials/addressbook/part5/addressbook.cpp instantiating findButton
-    \dots
-    \snippet tutorials/addressbook/part5/addressbook.cpp instantiating FindDialog
-
-    Next, we connect the \c{findButton}'s
-    \l{QPushButton::clicked()}{clicked()} signal to \c findContact().
-
-    \snippet tutorials/addressbook/part5/addressbook.cpp signals and slots for find
-
-    Now all that is left is the code for our \c findContact() function:
-
-    \snippet tutorials/addressbook/part5/addressbook.cpp findContact() function
-
-    We start out by displaying the \c FindDialog instance, \c dialog. This is
-    when the user enters a contact name to look up. Once the user clicks
-    the dialog's \c findButton, the dialog is hidden and the result code is
-    set to QDialog::Accepted. This ensures that
-    our \c if statement is always true.
-
-    We then proceed to extract the search string, which in this case is
-    \c contactName, using \c{FindDialog}'s \c getFindText() function. If the
-    contact exists in our address book, we display it immediately. Otherwise,
-    we display the QMessageBox shown below to indicate that their search
-    failed.

-/*!
-    \example tutorials/addressbook/part6
-    \title Part 6 - Loading and Saving
-    \brief Describes how to add save and load functionality.
-
-    This part covers the Qt file handling features we use to write
-    loading and saving routines for the address book.
-
-    \image addressbook-tutorial-part6-screenshot.png
-
-    Although browsing and searching the contact list are useful
-    features, our address book is not complete until we can save
-    existing contacts and load them again at a later time.
-
-    Qt provides a number of classes for \l{Input/Output and Networking}
-    {input and output}, but we have chosen to use two which are simple to use
-    in combination: QFile and QDataStream.
-
-    A QFile object represents a file on disk that can be read from and written
-    to. QFile is a subclass of the more general QIODevice class which
-    represents many different kinds of devices.
-
-    A QDataStream object is used to serialize binary data so that it can be
-    stored in a QIODevice and retrieved again later. Reading from a QIODevice
-    and writing to it is as simple as opening the stream - with the respective
-    device as a parameter - and reading from or writing to it.
-
-
-    \section1 Defining the AddressBook Class
-
-    We declare two public slots, \c saveToFile() and \c loadFromFile(), as well
-    as two QPushButton objects, \c loadButton and \c saveButton.
-
-    \snippet tutorials/addressbook/part6/addressbook.h save and load functions declaration
-    \dots
-    \snippet tutorials/addressbook/part6/addressbook.h save and load buttons declaration
-
-    \section1 Implementing the AddressBook Class
-
-    In our constructor, we instantiate \c loadButton and \c saveButton.
-    Ideally, it would be more user-friendly to set the push buttons' labels
-    to "Load contacts from a file" and "Save contacts to a file". However, due
-    to the size of our other push buttons, we set the labels to \uicontrol{Load...}
-    and \uicontrol{Save...}. Fortunately, Qt provides a simple way to set tooltips with
-    \l{QWidget::setToolTip()}{setToolTip()} and we use it in the following way
-    for our push buttons:
-
-    \snippet tutorials/addressbook/part6/addressbook.cpp tooltip 1
-    \dots
-    \snippet tutorials/addressbook/part6/addressbook.cpp tooltip 2
-
-    Although it is not shown here, just like the other features we implemented,
-    we add the push buttons to the layout panel on the right, \c buttonLayout1,
-    and we connect the push buttons' \l{QPushButton::clicked()}{clicked()}
-    signals to their respective slots.
-
-    For the saving feature, we first obtain \c fileName using
-    QFileDialog::getSaveFileName(). This is a convenience function provided
-    by QFileDialog, which pops up a modal file dialog and allows the user to
-    enter a file name or select any existing \c{.abk} file. The \c{.abk} file
-    is our Address Book extension that we create when we save contacts.
-
-    \snippet tutorials/addressbook/part6/addressbook.cpp saveToFile() function part1
-
-    The file dialog that pops up is displayed in the screenshot below:
-
-    \image addressbook-tutorial-part6-save.png
-
-    If \c fileName is not empty, we create a QFile object, \c file, with
-    \c fileName. QFile works with QDataStream as QFile is a QIODevice.
-
-    Next, we attempt to open the file in \l{QIODeviceBase::}{WriteOnly} mode.
-    If this is unsuccessful, we display a QMessageBox to inform the user.
-
-    \snippet tutorials/addressbook/part6/addressbook.cpp saveToFile() function part2
-
-    Otherwise, we instantiate a QDataStream object, \c out, to write the open
-    file. QDataStream requires that the same version of the stream is used
-    for reading and writing. We ensure that this is the case by setting the
-    version used to the \l{QDataStream::Qt_4_5}{version introduced with Qt 4.5}
-    before serializing the data to \c file.
-
-    \snippet tutorials/addressbook/part6/addressbook.cpp saveToFile() function part3
-
-    For the loading feature, we also obtain \c fileName using
-    QFileDialog::getOpenFileName(). This function, the counterpart to
-    QFileDialog::getSaveFileName(), also pops up the modal file dialog and
-    allows the user to enter a file name or select any existing \c{.abk} file
-    to load it into the address book.
-
-    \snippet tutorials/addressbook/part6/addressbook.cpp loadFromFile() function part1
-
-    On Windows, for example, this function pops up a native file dialog, as
-    shown in the following screenshot.
-
-    \image addressbook-tutorial-part6-load.png
-
-    If \c fileName is not empty, again, we use a QFile object, \c file, and
-    attempt to open it in \l{QIODeviceBase::}{ReadOnly} mode. Similar to our
-    implementation of \c saveToFile(), if this attempt is unsuccessful, we
-    display a QMessageBox to inform the user.
-
-    \snippet tutorials/addressbook/part6/addressbook.cpp loadFromFile() function part2
-
-    Otherwise, we instantiate a QDataStream object, \c in, set its version as
-    above and read the serialized data into the \c contacts data structure.
-    The \c contacts object is emptied before data is read into it to simplify
-    the file reading process. A more advanced method would be to read the
-    contacts into a temporary QMap object, and copy over non-duplicate contacts
-    into \c contacts.
-
-    \snippet tutorials/addressbook/part6/addressbook.cpp loadFromFile() function part3
-
-    To display the contacts that have been read from the file, we must first
-    validate the data obtained to ensure that the file we read from actually
-    contains address book contacts. If it does, we display the first contact;
-    otherwise, we display a QMessageBox to inform the user about the problem.
-    Lastly, we update the interface to enable and disable the push buttons
-    accordingly.

-/*!
-    \example tutorials/addressbook/part7
-    \title Part 7 - Additional Features
-    \brief Describes how to export data in VCard format.
-
-    This part covers some additional features that make the address
-    book more convenient for the frequent user.
-
-    \image addressbook-tutorial-part7-screenshot.png
-
-    Although our address book is useful in isolation, it would be
-    better if we could exchange contact data with other applications.
-    The vCard format is a popular file format that can be used for
-    this purpose.  Here we extend our address book client to allow
-    contacts to be exported to vCard \c{.vcf} files.
-
-    \section1 Defining the AddressBook Class
-
-    We add a QPushButton object, \c exportButton, and a corresponding public
-    slot, \c exportAsVCard() to our \c AddressBook class in the
-    \c addressbook.h file.
-
-    \snippet tutorials/addressbook/part7/addressbook.h exportAsVCard() declaration
-    \dots
-    \snippet tutorials/addressbook/part7/addressbook.h exportButton declaration
-
-    \section1 Implementing the AddressBook Class
-
-    Within the \c AddressBook constructor, we connect \c{exportButton}'s
-    \l{QPushButton::clicked()}{clicked()} signal to \c exportAsVCard().
-    We also add this button to our \c buttonLayout1, the layout responsible
-    for our panel of buttons on the right.
-
-    In our \c exportAsVCard() function, we start by extracting the contact's
-    name into \c name. We declare \c firstName, \c lastName and \c nameList.
-    Next, we look for the index of the first white space in \c name. If there
-    is a white space, we split the contact's name into \c firstName and
-    \c lastName. Then, we replace the space with an underscore ("_").
-    Alternately, if there is no white space, we assume that the contact only
-    has a first name.
-
-    \snippet tutorials/addressbook/part7/addressbook.cpp export function part1
-
-    As with the \c saveToFile() function, we open a file dialog to let the user
-    choose a location for the file. Using the file name chosen, we create an
-    instance of QFile to write to.
-
-    We attempt to open the file in \l{QIODeviceBase::}{WriteOnly} mode. If this
-    process fails, we display a QMessageBox to inform the user about the
-    problem and return. Otherwise, we pass the file as a parameter to a
-    QTextStream object, \c out. Like QDataStream, the QTextStream class
-    provides functionality to read and write plain text to files. As a result,
-    the \c{.vcf} file generated can be opened for editing in a text editor.
-
-    \snippet tutorials/addressbook/part7/addressbook.cpp export function part2
-
-    We then write out a vCard file with the \c{BEGIN:VCARD} tag, followed by
-    the \c{VERSION:2.1} tag. The contact's name is written with the \c{N:}
-    tag. For the \c{FN:} tag, which fills in the "File as" property of a vCard,
-    we have to check whether the contact has a last name or not. If the contact
-    does, we use the details in \c nameList to fill it. Otherwise, we write
-    \c firstName only.
-
-    \snippet tutorials/addressbook/part7/addressbook.cpp export function part3
-
-    We proceed to write the contact's address. The semicolons in the address
-    are escaped with "\\", the newlines are replaced with semicolons, and the
-    commas are replaced with spaces. Lastly, we write the \c{ADR;HOME:;}
-    tag, followed by \c address and then the \c{END:VCARD} tag.
-
-    \snippet tutorials/addressbook/part7/addressbook.cpp export function part4
-
-    In the end, a QMessageBox is displayed to inform the user that the vCard
-    has been successfully exported.
