How to receive events (eg. user mouse clicks) from IE

[calfdog at yahoo.com]

You also want to make sure the frame you want is loaded

I use the following method:

def _frameWait(self, frameName=None):

        thisCount = self._timeOut
        while self._ie.Busy:
            time.sleep(0.1)
            thisCount = thisCount - 1
            if thisCount == 0: break

        # wait for user specified Document to load
        doc = self._ie.Document.frames[frameName].Document
        # Check results
        bresult = False

        thisCount = self._timeOut #reset the timeout counter
        while doc.ReadyState != 'complete':
            time.sleep(0.1)
            thisCount = thisCount - 1
            if thisCount == 0: break
        if doc.ReadyState == 'complete':
            bresult = True
        if bresult == True:

            print "Using Frame: " ,frameName
        else:
            print " Loading . . ."
