title: how to get the selected combobox value from QTableWidget?
body: <p>I have created a QTableWidget in which for a column I am setting a combobox QComboBox using setCellWidget function. It works fine . </p>
  
  <p>This is how i set up the qtablewidget</p>
  
  <pre><code>cb = QComboBox()
  cb.addItems(["Java", "C#", "Python"])
  qtablewidget.setCellWidget(row_number, column_number , cb )
  </code></pre>
  
  <p>but now when I iterate through the QTableWidget , I cannot figure out how to get the selected value of the combobox for each row ?</p>
