how to close the window

[victor wang]

@Vinod-Kuntoji
I'm using both process->close(); and process->terminate(); none of those can work as i expect.

What else should i so ?

@victor-wang ,

Allocate the process in stack instead of heap

@victor-wang Did you try http://doc.qt.io/qt-5/qprocess.html#kill ?

[victor wang]

@jsulm
Yes, I did try this one.
But the window still not close either.

Hi,

Can you share the code used to start that application ?

[victor wang]

@SGaist
Sure, this is how i start my application.

/usr/share/qt5/examples/qt3d/anaglyph-rendering/anaglyph-rendering -platform wayland

I save it as a shell script and using QProcess to execute this .sh file.

Why are you using a shell script and not Process directly ?

[victor wang]

@SGaist
It's just because someone had done it before.
And i just using it by convenient.
Is that the reason why i can't close the window?

[victor wang]

@SGaist
You are right!
I try to using Process instead of shell script and it works as my expect!
Thanks a lot!

@SGaist
I still have a question.
Why i have to do it directly from Process but not shell script for instead?
I can't understand.
Could you tell me the difference between those two cases?

Number of layers: you are starting a shell that is starting an application so you'll be "communicating" with that shell but not with the application that was started with that shell.
