I am new in pyqt4 and I can't figure out how to do this. I have a QtableWidget with data in it. I want to change some background color of the tableWidget's cells.

I tried self.tableWidget.item(3, 5).setBackground(QtGui.QColor(100,100,150)) and it returns this error:

AttributeError: 'NoneType' object has no attribute 'setBackground'

What should I do?

You must first create an item in that place in the table, before you can set its background color.

self.tableWidget.setItem(3, 5, QtGui.QTableWidgetItem())
self.tableWidget.item(3, 5).setBackground(QtGui.QColor(100,100,150))
