[Qt-interest] how to capture the QProcess output?

[Muthulingam Ammaiappan]

Hi All,

now it is working fine...

i just replace the
"proc1->startDetached(svnprogram,arguments,workingdirpath);"

into "proc1->start(svnprogram,arguments);"..

thanks to all for your valuable suggestions...

Regards,
Muthu
