HI,
I have two sample QT4 GUI applications. With the help of my 1stApp I launch my 2ndApp using Qprocess. I linked the Qprocess readyReadStandardOutput() to my slot on 1stApp, so I can read the whatever data send by my 2ndApp.
Everytime I move my 2nd App window, I write the new window location to stdout using fprintf(), and I read this in my 1stApp slot as below
QProcess* p = (QProcess*) sender();
QByteArray outputText = p->readAllStandardOutput();
qDebug() << "TEST05:RECEIVED"<<outputText;
All is well. Effectively I can read the status of my 2ndApp from my 1stApp.
Now I want to control my 2ndApp from my 1stApp. But I can’t receive data in 2ndApp (send from 1stApp stdout).
I want to use something like below (This may be not correct as my 1stApp is not a Qprocess, so wouldn’t emit a readyReadStdout() signal)
connect(parent,SIGNAL(readyReadStdout()),this,SLOT(my2ndAppSlot()));
Is there a way I can connect my 1stApp stdout to a Qprocess (2nApp), so I can read the parent data?
Thanks in advance
