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