Answer 1

If you want your other thread to block until you get response (e,g: you want to ask a question and wait for the answer) you can use this function:

def runInGuiThreadAndReturnValue(self, fun, *args, **kwargs):
    def runInGui(fun, ret, args, kwargs):
        ret.append(fun( *args, **kwargs))
    ret = []
    sleeptime = kwargs.pop('sleeptime', 0.5)
    self.after(0, runInGui, fun, ret, args, kwargs)
    while not ret:
        time.sleep(sleeptime)
    return ret[0]
