QProcess timeout

**MonkeyJLuffy** · 22nd April 2010, 09:58

Hy everybody

I have a litlle problem, I would like to lauch an extern scrip using QProcess, and I would like to have a timeout.

But I couldn't use the waitForTimeout() methode, I need to use the Signal/slot.

My question is, if it have a possibility to set a timeout to the QProcess without using the method waitForTimeout() ?

Thank's

Check out the SIGNLAS of QProcess. There is a signal called finished(...) where you can get the exitcode and QProcess::ExitStatus too.

Yes i have readed it, but i would like to put a timeout to my process, different to the default timeout of QProcess. Then, when this timeout occure, QProcess send me the signal finished.

But the main problem is how to change the default timeout of QProcess without using waitForTimedout() ?

What mean "I couldn't use any method waitFor..." ? Why ?
PS.
I think that You must use extra QTimer to generate timeout.

It mean that the restriction of this program no let me use any "wait" that suspend the program

The timeout that i want is 300'000 ms and the default is 30'000, then the QTimer don't resolve my problem

Any other solucion ?

Create a QTimer, connect its timeout() signal to some slot and when the slot fires you will know the process timed out and you can kill it. If you receive the finished() signal before the timer times out you can stop the timer.
