Qt for Python (PySide/Shiboken)

The remaining issue seems to be in this part. When I enable the delegate on both widgets, it fails. self.journey_delegate = JourneyDelegate(self.tdt_model, self.day_type_model, self) # Apply RightToLeft to the left table self.table_widget.left_table.setLayoutDirection(Qt.RightToLeft) self.table_widget.left_table.setItemDelegate(self.journey_delegate) # self.table_widget.right_table.setItemDelegate(self.journey_delegate) When I explicitly make a left delegate and right delegate error gone.
