      <br>
      maybe what you want is "QtWidgets.qApp.processEvents()"? (make
      sure to look at the one with the optional argument for maxtime)<br>

        <div>When I'm building applications by wxPython, there is a
          function wx.MilliSleep could be used to do non-GUI-block
          sleep, while I cannot find the similar thing in PyQt, is it
          available or not? Otherwise, what I can do to is to use
          QThread. Any comment is appreciated!</div>
