Using QStringList.join you could achieve desired results ;

QStringList list = QStringList() << "one" << "two"; qDebug().noquote() << list.join(", ");

Playing around with this method quite likely gives you output you are after.

Hi @AnantAgrawal,

Just just launch your app from the console. qDebug, qWarning etc. will be printed to the console too (stdout/stderr). Make sure you don't define QT_NO_DEBUG_OUTPUT -- see http://doc.qt.io/qt-5/debug.html for more info.

qDebug().noquote() << QString("I have properly opened file %1").arg(fileName);

But please... don't use non-ascii characters in source code. That's just being mean to others.

@raoulh Thank you ...

OK guys, I was able to solve the problem. The Fedora people changed a configuration file, so that qDebug output wasn't shown to the user anymore, until the user changed the settings like described here:

@_JR_ You're welcome :) Personally I neither had any experience in writing iOS apps nor have the necessary hardware/keys/certificates for that. So any input on the subject will be useful (but I doubt that it will be possible to make any enhancements based on that).
