I try to run this command using QProcess
curl "http://dbpedia.org/data/Haeinsa.json" | perl dbpediaPlaceData.txt 'Haeinsa'I made QObject class and used timer . I can't get value from perlProcess.

AFAIK I have seen this post already this morning.
Now it seemed to be gone. Please do not delete a post and repost for catching attention.
