Invoking another application

[Qting]

I am creating an application which needs to invoke a different second application. I need that this invoked application does not die when the first application is closed. Is there a way ?

QProcess::startDetached()

QProcess::startDetached()

@wysota Thanks for the reply. I am trying to control a console application from a GUI application. Seems QProcess::StartDetached() would start the application but QProcess::Terminate() is causing Panic in the controlling application. Is there any way to close the console application from the GUI application ?

startDetached() is a static call, what do you want to call terminate() on?

I am sorry, I got confused..

The whole process that I want is:
1. User starts the GUI app
2. Through the GUI app, he starts the console app
3. The GUI app then may be closed
4. To close the console app, User starts the GUI app which would provide the interface
So, the startdetached() call could start the console app, I need some way to close the console app through the GUI app.

No, you need a way to communicate with the console app. You can do that with some IPC mechanism.
