57 Prints debug messages that include the file and line number for the-
58 specified QML \a object.-
59-
60 When QML types produce logging messages, it improves traceability-
61 if they include the QML file and line number on which the-
62 particular instance was instantiated.-
63-
64 To include the file and line number, an object must be passed. If-
65 the file and line number is not available for that instance-
66 (either it was not instantiated by the QML engine or location-
67 information is disabled), "unknown location" will be used instead.-
68-
69 For example,-
70-
71 \code-
72 qmlDebug(object) << "Internal state: 42";-
73 \endcode-
74-
75 prints-

112 \note In versions prior to Qt 5.9, qmlInfo reported messages using a warning-
