    Constructs a message box with a \a title, a \a text, an \a icon,
    and up to three buttons.

    The \a icon must be one of the following:
    \list
    \o QMessageBox::NoIcon
    \o QMessageBox::Question
    \o QMessageBox::Information
    \o QMessageBox::Warning
    \o QMessageBox::Critical
    \endlist

    Each button, \a button0, \a button1 and \a button2, can have one
    of the following values:
    \list
    \o QMessageBox::NoButton
    \o QMessageBox::Ok
    \o QMessageBox::Cancel
    \o QMessageBox::Yes
    \o QMessageBox::No
    \o QMessageBox::Abort
    \o QMessageBox::Retry
    \o QMessageBox::Ignore
    \o QMessageBox::YesAll
    \o QMessageBox::NoAll
    \endlist

    Use QMessageBox::NoButton for the later parameters to have fewer
    than three buttons in your message box. If you don't specify any
    buttons at all, QMessageBox will provide an Ok button.

    One of the buttons can be OR-ed with the QMessageBox::Default
    flag to make it the default button (clicked when Enter is
    pressed).

    One of the buttons can be OR-ed with the QMessageBox::Escape flag
    to make it the cancel or close button (clicked when \key Esc is
    pressed).

    \skipto // hardware failure
    \skipto QMessageBox mb("Application Name",
    \printuntil // try again

    If \a parent is 0, the message box becomes an application-global
    modal dialog box. If \a parent is a widget, the message box
    becomes modal relative to \a parent.

    The \a parent and \a f arguments are passed to
    the QDialog constructor.
