PyQt4 - creating a timer

Question

I\'m sorry for the question but I have read a bunch of things and it seems that I do not get how to make a timer. So I\'m posting my code:

from PyQt4 import         


        

Answer 1

Use new style signals, they are easier to understand.

Swap -

QtCore.QTimer.connect(timer, QtCore.SIGNAL("timeout()"), self, QtCore.SLOT("func()"))

With -

timer.timeout.connect(self.move_towards)   # assuming that move_towards is the handler

A simple but full example of a working timer -

import sys

from PyQt4.QtCore import QTimer
from PyQt4.QtGui import QApplication

app = QApplication(sys.argv)
app.setQuitOnLastWindowClosed(False)

def tick():
    print 'tick'

timer = QTimer()
timer.timeout.connect(tick)
timer.start(1000)

# run event loop so python doesn't exit
app.exec_()
