Just getting into playing with this. Not essential for me at the moment, but still curious. Is there some way to create a timed qmessagebox?

Basically, I have a loop that is happening and takes a while between iterations. I want to display a message box to the user after each iteration completes so they have a chance to cancel out of future iterations, if they want. I also do not want the user to have to be there for the process to continue, so if say 6 seconds pass it will just close the message box and continue on.

Thinking this might be a bit tricky since the message boxes are modal and interrupt the flow of the script.

Anybody out there have ideas for how to maybe achieve this?

As suggested in this answer, you could subclass QMessageBox to start a timer when showed. That calls close on itself when finished. 

class timedMessageBox(QtGui.QMessageBox):
    def __init__(self, timeout, message):
        super(timedMessageBox, self).__init__()
        self.timeout = timeout
        timeoutMessage = "Closing in {} seconds".format(timeout)
        self.setText('\n'.join((message, timeoutMessage)))

    def showEvent(self, event):
        QtCore.QTimer().singleShot(self.timeout*1000, self.close)
        super(timedMessageBox, self).showEvent(event)
