I also get the same error with the example included below. Any clues?


import sys
from PyQt4 import QtCore, QtGui


class TreeWidget(QtGui.QTreeWidget):
    def __init__(self, parent=None):
        QtGui.QTreeWidget.__init__(self, parent)

        # Add an item
        item = QtGui.QTreeWidgetItem(['1'], 0)
        self.addTopLevelItem(item)

        # Connect
        self.connect(self, QtCore.SIGNAL('itemDoubleClicked ( 
QTreeWidgetItem *, int)'), self.edit)

    def edit(self, item, column):
        print 'Clicked'

if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)

    widget = TreeWidget()
    widget.show()

    sys.exit(app.exec_())
