[Solved] How to show Qt debug messages outside the debugger

kamalakshantv

You can get some help using qInstallMsgHandler() from "this":http://lists.trolltech.com/qt-interest/2006-05/msg00602.html thread too.

QxtLogger can install itself the hander for Qt's debug messages as well, and you can use several outputs for your logging info. StdErr/StdOut of course, but also files in different formats.

The qt += console suggestion given earlier only works on windows.

[quote author="Volker" date="1293097794"]On Mac OS X the debug output goes to the system logger. You can read it with the Console Application (Usually in /Applications/Utilities/Console.app).

For your own logging facilities "qInstallMsgHandler()":http://doc.qt.nokia.com/latest/qtglobal.html#qInstallMsgHandler is your friend (that's the solution Gerolf mentioned).

I once wrote a small GUI that collects the qXXX() messages. I can put it in the wiki on request.[/quote]

I think it would be great if you could make your "small GUI that collects the qXXX() messages" available to everyone.

@Volker, that would be really nice of you.

Yes, everyone would like such a handy tool.

I've added a "wiki page":http://developer.qt.nokia.com/wiki/Browser_for_QDebug_output with the source code of the QDebug Log Output Browser.

I hope it is useful for somebody and of course feel free to ask, if you have questions.

Thanks Volker, I was also looking for something similar :)

Thanks Volker, fiddling with it at the moment... :-)

I added the .pro file, that was missing from the first version.
