<p>I have a code that display items (files) in a QlistWidget  where the user click on the item and the system display its content.</p>

<h1>example :</h1>

<ul>
<li>C:\Users\test\Desktop\New Microsoft Word Document.docx ==> row 0</li>
<li>C:\Users\test\Desktop\test_arabic.docx  ==> row 1</li>
</ul>

<p><strong>when  try to print the result  the system display the correct row number but wrong path, where it display the first selected  file path whatever you choose next</strong> </p>

<h1>code:</h1>

<pre><code>  def FileListSelected(self):             # Function to select the desired file from the list in the left pane
        ListIterator=range(self.listWidgetPDFlist.count() -1)

        for index in ListIterator:
            p = pathlib.Path(self.fullPath)
