Question

I’m trying to finish my project with Python and PyQt4 and I’m having an issue passing a QLineEdit variable through a function I made. The string should work as an url and when I pass it through my first argument, which tries to read the url and get its content, it throws me this error:

Traceback (most recent call last):
  File "programa2.py", line 158, in on_link_clicked
    download_mango(self.a, self.path2)

  File "c:\Users\Poblet\ManGet\mango.py", line 19, in download_mango
    urlContent = urllib2.urlopen(url).read() # We read the URL

  File "c:\Python27\lib\urllib2.py", line 126, in urlopen
    return _opener.open(url, data, timeout)

  File "c:\Python27\lib\urllib2.py", line 386, in open
    protocol = req.get_type()

AttributeError: 'QString' object has no attribute 'get_type'

Which is triggered by the following action:

def on_link_clicked(self):
    self.a = self.linkEdit.displayText()
    download_mango(self.a, self.path2)

And I’m completely lost. Could it be a PyQt4 issue or something wrong with my function?

I appreciate your help.

You didn’t post enough code to justify your statement that

The string should work as an url and when I pass it through my first argument

Looks like you are passing a QString into urlopen. Just wrap it in str() and you should be OK.

>>> url = QString('http://stackoverflow.com/questions/11121475')
>>> urllib2.urlopen(url).read()
### this generates your error ending with
AttributeError: 'QString' object has no attribute 'get_type'

>>> urllib2.urlopen(str(url)).read()
### works
