如何設置Qicon從PyQt的一個網址，你可以給我一個例子嗎？

Answer 1

一個基本的例子將是：

from PyQt4.QtGui import * 
from PyQt4.QtCore import QUrl 
from PyQt4.QtNetwork import QNetworkAccessManager, QNetworkRequest 

app = QApplication([]) 
url = "http://www.google.com/favicon.ico" 
lbl = QLabel("loading...") 
nam = QNetworkAccessManager() 

def finishRequest(reply): 
    img = QImage() 
    img.loadFromData(reply.readAll()) 
    lbl.setPixmap(QPixmap(img)) 

nam.finished.connect(finishRequest) 
nam.get(QNetworkRequest(QUrl(url))) 
lbl.show() 
app.exec_()
