How to redirect printf to QTextEdit?

[arcull]

Hi guys, I'm developing a desktop gui app which uses an open source library. The library uses a lot of "printf" statements, which are not seen on my app gui. So I thought of redirecting the printf to a QTextEdit on my app, but don't know how to do it. Till now I found a post on redirection of std::cout to a QTextEdit (http://stackoverflow.com/questions/1...to-a-qtextedit) which works ok, but I'd like to make something similar for "printf". Do you know how to do it (s short sample code would be perfect)? Is it possible at all? If not, what are the alternatives? Much thanks in advance.
