Starting an external process using QProcess in a plugin

[kim_aurore_biloni 0]

I'm developping a plugin for Cura. So I use PyQt5 and Uranium. I use the QProcess Object and start it... but nothing append. I use the log message to see if there is an error but it seems ok. I write the same code only in PyQt5 and it execute as expected.

 

I also tried to use the call function from subprocess (pyton 3) and same result when as using QProcess : external project ok ; Cura ko.

 

Do Cura have some restrictions ? How can I start my process from it ?
