There is no need for this Kai. The macro will not even create a QMessageLogger if the category is not enabled. Have a look in the qMessageFormatString of the QLog patch how I detect if I need to add a category or not. B.R.

I agree with that: On the desktop it's quite handy to see also detailed output on stderr/the shell (which one can redirect to a file if needed). But I also think that qLog() messages shouldn't show up by default for normal users, that is, unless the category has been explicitly enabled. So how about adding another QtMsgType called QLogMsg, that qLog() uses? In contrast to qDebug/QtDebugMsg, qLog/QtLogMsg messages would not be processed by default, unless the configuration file (or an environment variable) says so ...
