| \fn QDeclarativeInfo qmlInfo(const QObject *object) |

| |
| Prints warning messages that include the file and line number for the |
| specified QML \a object. |
| |
| When QML types display warning messages, it improves traceability |
| 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 MyCustomType (unknown location): component property is a write-once property |
| \endcode |
