[Qt-interest] Qt4 & fork()

[Scott Aron Bloom]

read the full docs.. You can use process in 2 ways.

The first, where you explicitly wait for it to start or exit...

The second, where you you connect to the qprocces's finished and started signals.  You start it in one method and then do your own thing, when its finished you have a slot that does your cleanup..

There are also io readt signals

Hi again

I've just found that QProcess does not start a new independent process, it blocks the main Qt application and returns/aborts immediatly if don't set a wait condition that I don't need just want to launch a command line application and let it run without taking future care of it, so, should I use QProcess + QThread? I think it should be easier to fork() and exec(), three of four lines of code should solve my problem since don't require communication with the new process, just to launch it... but my doubt remains, would fork() affect the Qt application or may get unstable?

Thanks

 I cannot answer your questions, but in my opinion you should look at the class QProcess, which is '
used to start external programs and to communicate with them'
