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.
