Q Process .setWorkingDirectory() pyqt

[jaybstory]

Hello,

I have a question. I have created a gui with two tabs, a settings tab and an application tab. In my settings tab, I am asking the user to input a path to his/her media player in a line edit. I would like to store the path from the line edit and be able to "call" this path via .setWorkingDirectory() using pyqt. I am using QProcess for my application tab because in that tab, the user can click open video which opens vlc. Attached are screenshots of my program. Thank you in advance.
