    \class QDebug

    \brief The QDebug class provides an output stream for debugging information.

    QDebug is used whenever the developer needs to write out debugging or tracing

    information to a device, file, string or console.

    \section1 Basic Use

    In the common case, it is useful to call the qDebug() function to obtain a

    default QDebug object to use for writing debugging information.

    \snippet doc/src/snippets/qdebug/qdebugsnippet.cpp 1

    This constructs a QDebug object using the constructor that accepts a QtMsgType

    value of QtDebugMsg. Similarly, the qWarning(), qCritical() and qFatal()

    functions also return QDebug objects for the corresponding message types.

    The class also provides several constructors for other situations, including

    a constructor that accepts a QFile or any other QIODevice subclass that is

    used to write debugging information to files and other devices. The constructor

    that accepts a QString is used to write to a string for display or serialization.

    \section1 Writing Custom Types to a Stream

    Many standard types can be written to QDebug objects, and Qt provides support for

    most Qt value types. To add support for custom types, you need to implement a

    streaming operator, as in the following example:

    \snippet doc/src/snippets/qdebug/qdebugsnippet.cpp 0

    This is described in the \l{Debugging Techniques} and

    \l{Creating Custom Qt Types#Making the Type Printable}{Creating Custom Qt Types}

    documents.

    \fn QDebug::QDebug(QIODevice *device)

    Constructs a debug stream that writes to the given \a device.

/*!

    \fn QDebug::QDebug(QString *string)

    Constructs a debug stream that writes to the given \a string.

*/

/*!

    \fn QDebug::QDebug(QtMsgType type)

    Constructs a debug stream that writes to the handler for the message type specified by \a type.

    \fn QDebug::QDebug(const QDebug &other)

    Constructs a copy of the \a other debug stream.

*/

/*!

    \fn QDebug &QDebug::operator=(const QDebug &other)

    Assigns the \a other debug stream to this stream and returns a reference to

    this stream.

*/

/*!

    \fn QDebug::~QDebug()

    Flushes any pending data to be written and destroys the debug stream.

/*!

    \fn QDebug &QDebug::space()

    Writes a space character to the debug stream and returns a reference to

    the stream.

    The stream will record that the last character sent to the stream was a

    space.

    \sa nospace(), maybeSpace()

*/

/*!

    \fn QDebug &QDebug::nospace()

    Clears the stream's internal flag that records whether the last character

    was a space and returns a reference to the stream.

    \sa space(), maybeSpace()

*/

/*!

    \fn QDebug &QDebug::maybeSpace()

    Writes a space character to the debug stream, depending on the last

    character sent to the stream, and returns a reference to the stream.

    If the last character was a space character, this function writes a space

    character to the stream; otherwise, no characters are written to the stream.

    \sa space(), nospace()
