Detailed Description

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.

See also QMessageLogger, QtMessageHandler, and qInstallMessageHandler().
