python - pyqt QTreeWidgetItem double click connect -

-

is possible connect doubleclick event qtreewidgetitem?

something this:

def test(self):         print("hello")  childitem = qtreewidgetitem()    childitem.doubleclicked.connect(self.test)

the signal want called itemdoubleclicked , belongs qtreewidget itself:

from pyqt4 import qtgui  def handler(item, column_no):     print(item, column_no)  def main():     app = qtgui.qapplication(sys.argv)     win = qtgui.qtreewidget()      items = [qtgui.qtreewidgetitem("item: {}".format(i)) in xrange(10)]     win.inserttoplevelitems(0, items)     win.itemdoubleclicked.connect(handler)      win.show()     sys.exit(app.exec_())  if __name__ == '__main__':     main()
