[Qt-interest] How to capture stdout and redirect it to the gui?

[K. Frank]

Hello Qt!

I would like to "capture" stdout and redirect it to a logging
window, for example, a QTextEdit.

Jochen Ulrich gave a good solution for doing this with std::cout
a few years back, see:

   http://lists.trolltech.com/qt-interest/2005-06/thread00166-0.html

I am using this, and it works well for std::cout, but now I
am using a C library that writes stuff to stdout (not C++'s
std::cout), and I would like to capture this output as well.

I am using Qt 4.6.1 on windows 7 with mingw.

This is not overly urgent.  I found a posting that shows how
to set "config += console" in the .pro file so that stdout output
will appear in the console window from which I launch my Qt
application.  So I can get the data this way, and make do.

But I would prefer, if possible, to display the output in the
gui, rather than a separate console window.

Would someone know of a solution or have suggestions about
things to try?

Thanks.
