Hi and welcome to devnet,
Nope that's not the same problem at all. The error suggest that you didn't implement the on_PTE_Output_textChanged slot.

I've moved your question to its own thread to keep the original thread clearer.
I'll let you mark it as solved using the "Topic Tool" button so that other forum users may know a solution has been found :)
