將文本文件中的項目添加到pyQt5中的QlistWidget中

我一直在研究這個代碼作爲我學校項目的一部分，我似乎沒有得到任何地方。我的問題是，當我嘗試從文件中添加文本到我的QlistWidget我的程序崩潰。首先我想知道這是否會將目錄中的文件（movieDir.txt中的每一行都是目錄）添加到QlistWidget，其次我甚至不確定是否使用了正確的窗口小部件或者它應該是QlistView。我怎樣才能做到這一點，所以listWidget中當前選定的項目在文本框中顯示細節（例如文件的大小）。將文本文件中的項目添加到pyQt5中的QlistWidget中

我也在尋找這個在啓動時完成，所以如果有人可以請告訴我在哪裏將不勝感激addItems(self)。因爲我們被忽視在學校教這個課，所以我是新來的。

我在Windows 7上

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)

這做了什麼，我問過，但它只能說明它作爲文本運行PyQt5，是有辦法顯示，而不是在目錄中的文件目錄作爲字符串？

如果您想要實時顯示目錄，可以使用'QListView'加上'QFileSystemModel'。否則，使用'self.listWidget.addItem（QListWidgetItem（icon，movie，self.listWidget）'''。這也會顯示圖標。 – Marcus
