Runtime output from stderror in Qt GUI programs
===

As you may or may not know from my last question, I'm currently in the middle of a development project using OpenCV on windows, developing a computer vision system for use with UAVs. I'm using Qt as a windowing system, since the highgui library included with OpenCV is primitive and I found I needed more functionality. Now that I've gone past highgui, I've found that I have a terrible time debugging runtime errors, because I get zero data from stderror. Normally, using OpenCV, if I call a function applicable to a grayscale image on an RGB one, it will throw an exception, print something to stderror, and terminate. Well, it seems that, at least on my system, Qt likes to hide output from stderror, and I no longer get these messages. This is making development incredibly slow and difficult, and as such I would like to correct it. 

Is there maybe a way to create a label in the UI, and link it to stderror? Or spawn a console window linked to stderror, at least for the debug version of the app?
