[Qt-interest] Waiting for QProcess to finish without freezing GUI

[qzvjtml02 at sneakemail.com]

Bob,

	I hadn't thought of looking at it, thanks! You don't think  
QThread::wait() will have the same effect as QProcess::waitForFinish()  
(i.e. freezing the GUI)? Also, I read that QThread::terminate() is  
"dangerous"– do you think it'd be safe to call it while the thread has  
a QProcess running?
