[PyQt] tooltips in menu: how?

[projetmbc]

V. Armando Solé is right. With this solution the tooltips come quickly 
in my computer. The corresponding PyQt code is :

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import sys
from PyQt4 import QtCore, QtGui, uic

class MainWindow(QtGui.QWidget):
    def __init__(self, parent=None):
        super(MainWindow, self).__init__(parent)
        self.setAttribute(QtCore.Qt.WA_DeleteOnClose)
        self.setAttribute(QtCore.Qt.WA_GroupLeader)
        self.menuI = QtGui.QPushButton("Menu")
        self.menuI.setToolTip("Click here...")
        self.menuI.setContextMenuPolicy(QtCore.Qt.ActionsContextMenu)

        mainLayout = QtGui.QHBoxLayout()
        mainLayout.addWidget(self.menuI)
        self.setLayout(mainLayout)
        self.resize(49,40)
        self.setWindowTitle("Qt menu")

        self.clicAct0 = QtGui.QAction("0", self)
        self.clicAct0.setToolTip("tooltip 0")
        self.connect(self.clicAct0, QtCore.SIGNAL("triggered()"), self.clic)

        self.clicAct1 = QtGui.QAction("1", self)
        self.clicAct1.setToolTip("tooltip 1")
        self.connect(self.clicAct1, QtCore.SIGNAL("triggered()"), self.clic)

        self.clicAct2 = QtGui.QAction("2", self)
        self.clicAct2.setToolTip("tooltip 2")
        self.connect(self.clicAct2, QtCore.SIGNAL("triggered()"), self.clic)

        menu0 = QtGui.QMenu(self)
        menu0.addAction(self.clicAct0)
        menu0.addAction(self.clicAct1)
        menu0.addAction(self.clicAct2)

        self.connect(menu0, QtCore.SIGNAL("hovered(QAction *)"),
        self._actionHovered)
       
        menu1 = QtGui.QMenu(self)
        menu1.setTitle("submenu")
        menu1.setToolTip("tooltip submenu")

        menu1_0 = QtGui.QAction("subentry",self)
        menu1_0.setToolTip("tooltip subentry")

        self.connect(menu1_0, QtCore.SIGNAL("triggered()"), self.clic)
        menu1.addAction(menu1_0)
        menu0.addMenu(menu1)
        self.menuI.setMenu(menu0)

    def clic(self):
        print "clic"

    def _actionHovered(self, action):
        tip = action.toolTip()
        QtGui.QToolTip.showText(QtGui.QCursor.pos(), tip)

def main():
    app = QtGui.QApplication(sys.argv)
    locale = QtCore.QLocale.system().name()
    appTranslator = QtCore.QTranslator()
    app.setApplicationName(app.translate("main", "qtmenu"))

    form = MainWindow()
    form.show()
    app.exec_()

if __name__ == "__main__":
    main()
