Now I have done it. I send my solution here for information for newcommers of
for if experts has better way to do it.

In my thread:

#gui: main widget
#id: message number
#s: message contents
def sendInformation(id,s,gui):
        number=QtCore.QEvent.Type(QtCore.QEvent.User+1)
	event=QtCore.QEvent(number)
	QtGui.QApplication.sendEvent(gui,event)


In QMainWindow constructor I have added:
self.installEventFilter(self)

And then this method:
        def eventFilter(self,object,event):
                if (event.type() == QtCore.QEvent.Type(QtCore.QEvent.User+1)):
                        print "Here"
                        return True
                        #self.progressbar.setProgress(int(a0.data()))

                return QtGui.QWidget.eventFilter(self,object,event);

Thanks!
