title: How to use findChildren?
body: <p>I want to click a button and clear around 20 QLineEdits.</p>
  
  <p>I am trying to use findChildren() and put all the QLineEdit in a QListWidget</p>
  
  <pre><code>self.StudentAdmissionLayout = QGridLayout()
  self.StudentAdmissionLayout.addWidget(self.StudentName,1,0,1,1)
  </code></pre>
  
  <p>The self.StudentAdmissionLayout layout has all the QLineEdit placed on it.</p>
  
  <pre><code>self.myList = QListWidget()
  self.Item = QListWidgetItem()
  self.Item = self.StudentAdmissionLayout.findChildren(QLineEdit)
  self.myList.addItem(self.Item)
  </code></pre>
  
  <p>I am getting below error:</p>
  
  <pre><code>TypeError: arguments did not match any overloaded call:
  QListWidget.addItem(QListWidgetItem): argument 1 has unexpected type 'list'
  QListWidget.addItem(QString): argument 1 has unexpected type 'list'
  </code></pre>
  
  <p>I am trying to put the above 4 lines in a loop. But the 3rd line isn't working, I am not sure how to make it work.
  Please suggest.</p>
