QTimer Not Firing, very strange...

:cool:

Code:

---

from PyQt5.QtCore import QObject, QTimer, pyqtSignal
from urllib import request
import xml.etree.ElementTree as ET
from datetime import datetime, time
 
class SignalSource(QObject):
    valuesChecked = pyqtSignal(dict)
 
    def __init__(self, xmlUrl, timerIntervalMs=10):
        QObject.__init__(self)
        self.xmlUrl = xmlUrl
        self.timer = QTimer()
        self.timer.setInterval(timerIntervalMs)
        self.timer.timeout.connect(self.timerFires)
        self.timer.start()
 
        self.sample = {}
 
    def getSample(self, sourcePiece):
        return self.sample[sourcePiece[0], sourcePiece[1]]
 
    def timerFires(self):
        response = request.urlopen(self.xmlUrl)
        xmlStr = response.read()
        root = ET.fromstring(xmlStr)
 
        for child in root:
            asset = child.attrib["Symbol"]
            self.sample[asset] = { 
                "bid": float(child.find("Bid").text), 
                "ask": float(child.find("Ask").text),
                "high": float(child.find("High").text),
                "low": float(child.find("Low").text),
                "@ last": time(child.find("Last").text),
                "direction": int(child.find("Direction").text),
                }
        self.valuesChecked.emit(self.sample)

I simply call
signalSource = SignalSource("myXmlUrl")
inside the main debug module at module scope.

No timer firing action, so I never get to take a sample :'(

Is the event loop running?

What does your main program do after the line

Code:

---

signalSource = SignalSource("myXmlUrl")

? You need to run an event loop to receive timer events.
