[Qt-interest] QProcess for a prompted program

[Gerardo Gutierrez]

I want to run an external program which is prompted (specifically gnuplot)
and communicate with it writing on his prompt.
I don't use writeToStdin() function because I'm using Qt4:


process::process(QString progname)
program->start(progname,QIODevice::ReadWrite);
qDebug()<<program->isWritable();
// program->execute(proc);
qDebug()<<"paso execute";


program->write("plot sin(x) pause -1");
qDebug()<<"paso plot";
}


I added the start function because the program wasn't writable without it.
