AFAIK: no. And worse, a barrage of debugging output can clog up your 
entire QtCreator.
One way to get around the issue would be to pipe the output to a file 
instead. That is practically endless. You can do that by running from 
the command line or perhaps even by modifying the run command for your 
project in Qt Creator. Downside is that you don't get the ouput in Qt 
Creator anymore (unless you manage to work around that with 'tee'?).

What I sometimes do is to limit the number of messages a piece of code 
may generate. I also have pieces of code where the rule is: if it goes 
wrong once, it goes wrong thousands of times. So, I keep a static 
counter (in debug mode) that I use to limit how many times the error is 
outputted. After that, further errors are simply ignored. That usually 
works fine for me.
