    \class QDialogButtonBox
    \since 4.2
    \brief The QDialogButtonBox class is a widget that presents buttons in a
    layout that is appropriate to the current widget style.

    \ingroup dialog-classes


    Dialogs and message boxes typically present buttons in a layout that
    conforms to the interface guidelines for that platform. Invariably,
    different platforms have different layouts for their dialogs.
    QDialogButtonBox allows a developer to add buttons to it and will
    automatically use the appropriate layout for the user's desktop
    environment.

    Most buttons for a dialog follow certain roles. Such roles include:

    \list
    \o Accepting or rejecting the dialog.
    \o Asking for help.
    \o Performing actions on the dialog itself (such as resetting fields or
       applying changes).
    \endlist

    There can also be alternate ways of dismissing the dialog which may cause
    destructive results.

    Most dialogs have buttons that can almost be considered standard (e.g.
    \gui OK and \gui Cancel buttons). It is sometimes convenient to create these
    buttons in a standard way.

    There are a couple ways of using QDialogButtonBox. One ways is to create
    the buttons (or button texts) yourself and add them to the button box,
    specifying their role.

    \snippet examples/dialogs/extension/finddialog.cpp 1

    Alternatively, QDialogButtonBox provides several standard buttons (e.g. OK, Cancel, Save)
    that you can use. They exist as flags so you can OR them together in the constructor.

    \snippet examples/dialogs/tabdialog/tabdialog.cpp 2

    You can mix and match normal buttons and standard buttons.

    Currently the buttons are laid out in the following way if the button box is horizontal:
    \table
    \row \o \inlineimage buttonbox-gnomelayout-horizontal.png GnomeLayout Horizontal
         \o Button box laid out in horizontal GnomeLayout
    \row \o \inlineimage buttonbox-kdelayout-horizontal.png KdeLayout Horizontal
         \o Button box laid out in horizontal KdeLayout
    \row \o \inlineimage buttonbox-maclayout-horizontal.png MacLayout Horizontal
         \o Button box laid out in horizontal MacLayout
    \row \o \inlineimage buttonbox-winlayout-horizontal.png  WinLayout Horizontal
         \o Button box laid out in horizontal WinLayout
    \endtable

    The buttons are laid out the following way if the button box is vertical:

    \table
    \row \o GnomeLayout
         \o KdeLayout
         \o MacLayout
         \o WinLayout
    \row \o \inlineimage buttonbox-gnomelayout-vertical.png GnomeLayout Vertical
         \o \inlineimage buttonbox-kdelayout-vertical.png KdeLayout Vertical
         \o \inlineimage buttonbox-maclayout-vertical.png MacLayout Vertical
         \o \inlineimage buttonbox-winlayout-vertical.png WinLayout Vertical
    \endtable

    Additionally, button boxes that contain only buttons with ActionRole or
    HelpRole can be considered modeless and have an alternate look on Mac OS X:

    \table
    \row \o modeless horizontal MacLayout
         \o \inlineimage buttonbox-mac-modeless-horizontal.png Screenshot of modeless horizontal MacLayout
    \endtable

    When a button is clicked in the button box, the clicked() signal is emitted
    for the actual button is that is pressed. For convenience, if the button
    has an AcceptRole, RejectRole, or HelpRole, the accepted(), rejected(), or
    helpRequested() signals are emitted respectively.

    If you want a specific button to be default you need to call
    QPushButton::setDefault() on it yourself. However, if there is no default
    button set and to preserve which button is the default button across
    platforms when using the QPushButton::autoDefault property, the first push
    button with the accept role is made the default button when the
    QDialogButtonBox is shown,
