[PyQt] wx.MilliSleep equivalent

[Chris Pezley]

I misread the description of the wait argument in processEvents. It 
looks like it will return earlier if it can. You'll have to define your 
own blocking processEvents:


import time

from PyQt5 import QtWidgets


def processWait(time_to_block):
     """
     :param time_to_block: The time to block in seconds.
     :type time_to_block:  float
     """
     start_time = time.time()

     # Keep processing events until we've exceeded the specified time.
     while time.time() - start_time < time_to_block:
         QtWidgets.qApp.processEvents()
