according to this documentation: http://doc.qt.io/qt-5/qtglobal.html#qDebug which is also referenced in the link you provided it says that if you write: qDebug() << "Debug" there should be output unless QT_NO_DEBUG_OUTPUT is defined. there is no mention that the logging category filters this messages, I guess in this case the category is "default" If you consider this a QT documentation problem, I will write a separate report to QT bug tracking system.
