Hi, I just started learning Python :D

I'm making a simple script with a GUI, reading from a text file, but the problem is that the contents won't insert into the text area, though they do print ok in the console window. Here is my code, can you see what I am doing wrong? (in the def open_file(self) section)

Notepad 2

Acts like Notepad
