详细描述
The QMessageLogContext class provides additional information about a log message.
The class provides information about the source code location a qDebug(), qInfo(), qWarning(), qCritical() or qFatal() message was generated.
Note: By default, this information is recorded only in debug builds. You can overwrite this explicitly by defining QT_MESSAGELOGCONTEXT or QT_NO_MESSAGELOGCONTEXT.
