Here is the solution:
1. delete/comment only the following line:
#self.centralwidget.setSortingEnabled(__sortingEnabled)

Then code:
[code]
def eqpt_centralwdg(self,MainWindow):
    self.centralwidget = QtGui.QWidget(MainWindow)
    self.centralwidget.setObjectName("centralwidget")

    self.colorTreeWidget = QtGui.QTreeWidget(self.centralwidget)
    self.colorTreeWidget.setGeometry(QtCore.QRect(60, 60, 191, 141))
    self.colorTreeWidget.setObjectName("colorTreeWidget")

    item = QtGui.QTreeWidgetItem(self.colorTreeWidget)
    item = QtGui.QTreeWidgetItem(self.colorTreeWidget)

    self.connect(self.colorTreeWidget,
QtCore.SIGNAL('itemClicked(QTreeWidgetItem*, int)'),
self.eqpt_activateInput)

    MainWindow.setCentralWidget(self.centralwidget)

def eqpt_activateInput(self,item,col):
    print "Qtree ok! pressed"
    print item.text(col)
[/code]

Hope this may help others too.
