QProcess Problem

[pmabie]

Hi!
Using CentOS 5.2 , KDevelop 3.5, KDE 3.59


m_Process = new QProcess(this);
connect(m_Process,SIGNAL(readyReadStandardOutput() ), this,SLOT(ProcessLine()));
m_Process->setProcessChannelMode(QProcess::ForwardedChannels) ;
m_Process->exec(app,args);
if (m_Process->waitForFinished())
return;

My Program is a simple wrapper for p7Zip, I got everything to work except the progressbar, I read in the docs that QProcess::exec forwords the output of the child process to the main process.

How do I get this info .

ps: I did try (this) in the connect function , but the output on the compiler window told me that there was no signal by that name.

Thanks for your help!
Patrick.

if (m_Process->waitForFinished())
If you will wait for the process here, your GUI won't work, because you will block the event loop. Better connect to the finished() signal.

How did you declare ProcessLine slot?

public slot

Did you remember about Q_OBJECT macro?

Could you post the exact error message? Maybe there's a typo in slot name?

[pmabie]

Sure will .

here's my problem , can I get the Standard out that is being sent to my program from the QProcess?

Thanks.

When you make that ProcessLine() slot work, you can use QProcess::readAll() or QProcess::readLine().
