This is a workaround, but you could probably install your own message handler. Take a look at qInstallMsgHandler in the documentation if you have not done so already.

I have a similar issue on Ubuntu 9.10 with Qt Creator 2.0 and Qt 4.7.0, though I don't see stdout output until the application is closed. It is as if the buffer isn't flushed. Printing to stderr shows the output in the Application output window immediately though.

fprintf(stderr, "Test1 \n"); // Prints immediately
fprintf(stderr, "Test2 \n\r"); // Prints immediately
fprintf(stdout, "Test3 \n"); // Delayed until app termination
fprintf(stdout, "Test4 \n\r"); // Delayed until app termination
qDebug() << "Test6 \n\r"; // Does not print at all
