(PyQt4) QtGui QListWidget adding new item problem

Hi everyone.

At first:

1. My sys.version output:
   2.7.3 (default, Aug 1 2012, 05:16:07)
   [GCC 4.6.3]
2. My OS:
   bq. Ubuntu
   Release 12.04 (precise) 32-bit

I used Qt 4 Designer for my GUI. And made a form contains a QListWidget and a QPushButton. Then used this command line for converting XML file to py file:

Code:

---

pyuic4 -x blabla.ui -o c.py

---

I want to add numbers to list widget when button clicked. I wrote the code below. It can add a blank row and fill it with firs number. In second loop it add a blank row and print this error:

Traceback (most recent call last):
File "b.py", line 48, in selectFile
self.listWidget.item = self.listWidget.item(x)
TypeError: 'QListWidgetItem' object is not callable

Here is my code:
