Hi,

I got _AttributeError: 'NoneType' object has no attribute 'text'_ at line 35 from the code below.

In addition, I tested the index value and it seems to be correct.

Any ideas why i get a NoneType?


Qt Code: 
  1. from PySide.QtCore import Slot
  2. from PySide import QtGui, QtCore
  3.  
  4. class Output(object):
  5.  
  6.     def __init__(self, physical_type):
  7.         ''' '''
  8.         self.group_box = QtGui.QGroupBox('Output')
  9.         self.layout = QtGui.QVBoxLayout()
  10.         self.layout.addWidget(self.group_box, 1)
  11.  
  12.         self.tabs = QtGui.QTabWidget()
  13.  
  14.     def run(self):
  15.         self.tabs.addTab(self.__genTable(), "None")
  16.  
  17.         form_layout = QtGui.QFormLayout(self.group_box)
  18.         form_layout.addWidget(self.tabs)
  19.  
  20.         return self.layout
  21.  
  22.     def __genTable(self, rows = 4, columns = 2):
  23.         table_view = QtGui.QTableWidget(rows,columns)
  24.  
  25.         table_view.setContextMenuPolicy(QtCore.Qt.CustomContextMenu)
  26.         table_view.setSelectionBehavior( QtGui.QTableView.SelectItems )
  27.  
  28.         table_view.horizontalHeader().sectionDoubleClicked.connect(self.changeHorizontalHeader)
  29.  
  30.         return table_view
  31.  
  32.  
  33.     def changeHorizontalHeader(self, index):
  34.         model = self.tabs.currentWidget()
  35.         oldHeader = model.horizontalHeaderItem(index).text()
  36.         newHeader, ok = QtGui.QInputDialog.getText(QtGui.QInputDialog(),
  37.                                                    'Change header label for column {}'.format(index),
  38.                                                    'Header:',
  39.                                                    QtGui.QLineEdit.Normal,
  40.                                                    oldHeader)
  41.         if ok:
  42.             self.tabs.currentWidget().setText(newHeader)
