Hi,

You will stop at nothing to reach your objective, but only because your
brakes are defective.
from PyQt4.QtGui import *
from PyQt4 import QtCore
class mywid(QWidget):
def __init__(self, parent=None):
QWidget.__init__(self, parent)
self.tree=QTreeWidget()
self.tree.setColumnCount(1)
self.lay=QVBoxLayout(self)
self.lay.addWidget(self.tree)
item=QTreeWidgetItem(self.tree)
item.setText(0, "ROOT")
item2=QTreeWidgetItem(self.tree)
item2.setText(0, "ITEM2")
item.addChild(item2)
self.tree.addTopLevelItem(item)
self.connect(self.tree, QtCore.SIGNAL("itemSelectionChanged()"), self.treeSel)
def treeSel(self):
print "Selection"
import sys
app=QApplication(sys.argv)
w=mywid()
QtCore.QObject.connect(w, QtCore.SIGNAL("close()"), app.quit)
w.show()
app.exec_()
