Signal In Pyside Not Emitted When Called By A Timer

I need to emit a signal periodically. A timer executes certain function, which emits the signal that I want. For some reason this function is not being emitted. I was able to repro

Solution 1:

As @ekhumoro said in the comments, QTimer helped a lot. I needed an event-loop. I'm posting the code to make the answer valid. I rewrote it using QTimer, which made everything simpler really. Note that I need to call QCoreApplication to run the threads. Again, this is just the minimal code to reproduce what I needed to do.

import time
from PySide import QtCore
from probeConnection import ProbeConnection 

classtestSignals(QtCore.QObject):

    def__init__(self):
        self.timer = QtCore.QTimer()
        self.timer.timeout.connect(self.tick)
        self.start()

    deftick(self):
        print("tick")

    defgetData(self):
        return time.strftime('%H:%M:%S')

    defstart(self):
        self.timer.start(1000)

    defstop(self):
        self.timer.stop()

classtestConnection():
    defreceiveMe(self):
        print('time: ' + self.test.getData())

    def__init__(self):
        self.test = testSignals()
        self.test.timer.timeout.connect(self.receiveMe)


app = QtCore.QCoreApplication([])
test = testConnection()
timer = QtCore.QTimer()
timer.singleShot(4000,app.exit)
app.exec_()

it produces:
