如何檢索縮略圖並將其顯示爲QListwidget項目？

我想直接從http://i.ytimg.com/直接閱讀縮略圖，而不使用谷歌gdata服務。誰能幫我？如何檢索縮略圖並將其顯示爲QListwidget項目？

`enter code here` 

#!/usr/bin/env python 
#_*_ encoding: UTF-8 _*_ 

from PyQt4.QtGui import QImageReader 

from PyQt4.QtNetwork import (QNetworkRequest, QNetworkReply, QNetworkAccessManager) 

from PyQt4.QtCore import QUrl 


def getThumbnails(self,numTitles): 

    thumbs = [] 
    thumbs[:]= [] 

    nam = QNetworkAccessManager() 

    for i in xrange(numTitles): 
     url = QUrl("http://i.ytimg.com/vi/" + self.tubeLinks[i] + "/default.jpg") 
     request = QNetworkRequest(url) 
     reply = nam.get(request) 
     image_reader = QImageReader(reply) 
     thumbs.append(image_reader.read()) 

    return thumbs

我delimmas是：

1.-如何測試拇指是否被成功讀取？

2.-如何將它們添加到QListWidget項目使用pixmap？
