I don’t know what the problem was but well done figuring it out.
And thanks for giving the solution, in case someone else needs python + qt development tips for a similar case.antiX Live system enthusiast.

And thanks for giving the solution, in case someone else needs python + qt development tips for a similar case.Same; I am not certain what the original problem was. The interactive cli terminal output would have failed due to calling “-l” as a separate process from ls instead of an argument to ls. Not certain on the relationship to the script however. Unless it was expected to work when the button was pressed… but the button press call to the fthunar function is commented out. Good to see Qprocess works though
