Writting commands to console application from Qt

[mandruk1331]

I have a GUI application in which I want to call an external console program in which I would like to write commands from Qt and get some data. I have found smth in the docs but, as far as I understood I have to call everytime the start method and pass the command in the start command. is there I can create smth like a buffer so I could write to it the commands I want to execute?
