transfer data between threads in PyQt

I create signal in start function $in the other words - "wait for signal"$:

self.connect$self.s1,QtCore.SIGNAL('printStat(PyQt_PyObject$'),self.printStat)

s1 - child thread;
printStat$PyQt_PyObject$ - signal name, which send from thread s1 to main thread;
self.printStat  - function for our reaction by signal $self = QMainWindow($ ).

I create sending signal in child thread:

self.emit$QtCore.SIGNAL('printStat(PyQt_PyObject$'), $$list of transfer vars$$ )

I can transfer any PyQt- or/and Python-objects.

Function printStat must get transfer objects:

    def printStat(self, [list of transfer vars]):
