[FIXED] QImage: URL instead of file path?

Issue

This code assigns a raster pixmap to a label. Instead of generating one I could simply read a local file:

img = QtGui.QImage('/Users/user/Desktop/photo.jpg')

I wonder if there is a way to specify the URL link instead of file path? Then QLabel would get its pixmap straight from a web?

from PyQt4 import QtCore, QtGui


if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)
    if not QtGui.QApplication.instance():
        app=QtGui.QApplication([])

    window = QtGui.QWidget()
    window.setLayout(QtGui.QVBoxLayout())

    img = QtGui.QImage(32, 32, QtGui.QImage.Format_RGB32)
    img.fill(QtCore.Qt.red)

    pixmap = QtGui.QPixmap(img)
    lbl = QtGui.QLabel()
    lbl.setPixmap(pixmap)

    icon = QtGui.QIcon(pixmap)
    window.layout().addWidget(lbl)

    window.show()
    sys.exit(app.exec_())

Solution

To my knowledge, there is no direct way of getting a QImage or QPixMap to load data straight from a URL. But you can bypass that by first extracting the data from the URL, and then loading it to a QPixMap.

Get data from the URL:

import urllib2 
url_data = urllib2.urlopen(path).read()

Now load it to your QPixMap:

pixmap = QPixmap()
pixmap.loadFromData(url_data)
lbl.setPixmap(pixmap)

It is worth saying you should try and catch exceptions like urllib2.URLError or InvalidURL, handle cases where the URL is secured (https) etc.
