[PyKDE] Help with QListViewItem

[Per Gummedal]

I have this simple source.

#!/usr/bin/env python

import string, sys
from qt import *

class List(QListView):
        def __init__(self, *args):
                apply(QListView.__init__,(self,) + args)
                self.addColumn("A")
                self.addColumn("B")
                self.setShowSortIndicator(1);
                self.data = (['1','2'], ['11','12'],['2','3'])
                for row in self.data:
                        item = ListItem(self)
                        for i in range(len(row)):
                                item.setText(i, row[i])

class ListItem(QListViewItem):
        def __init__(self, *args):
                apply(QListViewItem.__init__,(self,) + args)

        def key(self, col, asc):
                print 'key'
                return string.rjust(str(self.text()),2)

a = QApplication(sys.argv)
mw = List()
a.setMainWidget(mw)
mw.show()
a.exec_loop()

When I click on the columnheaders to sort, method key is not called.
What am I doing wrong, any ideas ?
