Adding items from a text file to QlistWidget in pyQt5

Question

I've been working on this code as part of my school project and i don't seem to be getting anywhere. My problem is when i try add the text from a file to my QlistWidget my program crashes. Firstly I want to know if this will add the files at the directory (each line in movieDir.txt is a directory) to the QlistWidget, secondly I'm not even sure if I'm using the right widget or if it should be QlistView. Also how would i make it so the currently selected item in the listWidget shows details in the text box (e.g. size of the file).

I'm also looking for this to be done on start up so if someone can please tell me where to the the addItems(self) that would be greatly appreciated. I'm new to using classes as we have been neglected to be taught this in school.

I'm running PyQt5 on windows 7

Answer 2

    self.listWidget = QtWidgets.QListWidget(self.centralWidget)
    self.listWidget.setObjectName("listWidget")
    self.horizontalLayout_4.addWidget(self.listWidget)

    with open('moviesDir.txt','r') as movieDir:
        for movie in movieDir:
            self.listWidget.addItem(movie)

This did what i asked, but it only shows it as text, is there a way to show the files at the directory instead of the directory as a string?
