On the !PyQt mailing list, Adam W. asked for "[[http://www.riverbankcomputing.com/pipermail/pyqt/2009-September/024242.html|A simple way to add another column to QComboBox?]]". Here is some sample code that does this:

{{{
#!python
import sys
from PyQt4.QtCore import Qt, QVariant
from PyQt4.QtGui import *


app = QApplication(sys.argv)
model = QStandardItemModel()

items = [("ABC", True),
         ("DEF", False),
         ("GHI", False)]

for text, checked in items:

    text_item = QStandardItem(text)
    checked_item = QStandardItem()
    checked_item.setData(QVariant(checked), Qt.CheckStateRole)
    model.appendRow([text_item, checked_item])

view = QTreeView()
view.header().hide()
view.setRootIsDecorated(False)

combo = QComboBox()
combo.setView(view)
combo.setModel(model)
combo.show()

sys.exit(app.exec_())
}}}

Note that we set the model on the combo box, not the view.

Some improvements could be made to this code. For example, at small sizes the pop-up doesn't always show both columns. Perhaps the combo box's [[http://qt.nokia.com/doc/4.5/qcombobox.html#sizeAdjustPolicy-prop|sizeAdjustPolicy]] property would help with this.

An alternative way to display custom items in the combo box would be to implement a custom item delegate and set that on the combo box.
