\fn QmlInfo qmlInfo(const QObject *object)
\brief Prints warnings messages that include the file and line number for QML types.
When QML types display warning messages, it improves tracibility
if they include the QML file and line number on which the
particular instance was instantiated.
To include the file and line number, an object must be passed. If
the file and line number is not available for that instance
(either it was not instantiated by the QML engine or location
information is disabled), "unknown location" will be used instead.
For example,
\code
qmlInfo(object) << tr("component property is a write-once property");
\endcode
prints
\code
QML ComponentInstance (unknown location): component property is a write-once property
\endcode
