thanks david,

i was looking for a code example of that. all the examples i found are using
existing 'events' like clicked() of a button.

figured it out in the end so for others looking for something similar:

i ended up creating a function like:

def startMyMove(self):
     self.movie.setPaused(False)

def stopMyMove(self):
     self.movie.setPaused(False)

linking them like

        self.connect(self, QtCore.SIGNAL("startMyMovie()"),
self. startMyMovie )
        self.connect(self, QtCore.SIGNAL("stopMyMovie()"),
self. stopMyMovie )

in the constructor

and when i want it to start or stop i call :

self.emit(QtCore.SIGNAL("startMyMovie()") )
or
self.emit(QtCore.SIGNAL("stopMyMovie()") )

from within the thread

seems to work

thanks all !!
