python - equivalent to time.sleep?

Question

I can't use time.sleep in my pyqt application because that freezes the GUI thread, so the GUI will be completely frozen during this time.I have been looking for a way to handle this.

I tried to use QTimer, but it seemed like they need to be linked to another function? Like wait ten seconds then run some function. Is there a way to just have it wait then continue with the current function?

def num(self):
    for i in range(1,999):
        print i
        #Add some sleep here

def testSleep(self):
    QtCore.QTimer.singleShot(2000, self.num)

Answer 1

Actually i was looking for time.sleep alternative to use in pyqt without using any thread concepts.

And the solution i figured out is:

from PyQt4 import QtTest

QtTest.QTest.qWait(msecs)

This works similar to time.sleep making GUI responsive.

Thankyou for your answers.
