I have QProcess working fine, but I wanted to declare "QProcess *proc" at the top of the source (.cpp) file, so it's visible in more than one event handler. This causes make errors and/or segfaults. I've tried "proc->start(appString,argList);", and tried preceding with "*", "&". I also tried "." in place of "->". (Using Qt4, by the way). Does anyone know how to do this? Forgive me if this has been asked before, I wasn't sure what to search to find the answer.
