Problem with qprocess

[jacek]

what that they expected to have. stderr messages in err file, and stdout menu in out file.

OK, so at least that application isn't playing any tricks by detecting whether the input comes from a file or a terminal.

There is no way to control the buffers through QProcess, but maybe reimplementing QProcess::setupChildProcess() will help. You might try to alter the buffer size with setbuf, but I'm not sure if it's going to work (I think I've tried it to solve a similar problem, but without a success).

Do you know any (not-very-complicated) (especially in Qt4) application with similar functionality?

Unfortunately, I don't.

I reviewed konsole code, but got lost in (kde-related) classes....

kconsole doesn't use pure QProcess, but a K3Process subclass. The most important difference is that KDE allows you to use a pty device to communicate with the child process.
