线程拦截GUI

Question

我有一个解析ListCtrl的双向面板。我仍然从这个帖子中阻止了我的GUI：

class MyThread(threading.Thread):    
    def __init__(self, DirQ, new_dbfQ, RemoveQ):
        threading.Thread.__init__(self)

        self.DirQ = DirQ
        self.new_dbfQ = new_dbfQ
        self.RemoveQ = RemoveQ

    def run(self):
        """ worker """
        self.OpenDir = self.DirQ.get()
        self.new_dbf = self.new_dbfQ.get()
        self.RegRemove = self.RemoveQ.get()

        with open(str(self.OpenDir), 'r') as infile: 
            reader = csv.reader(infile)
            data = StringIO()

            writer = csv.writer(data)
            for line in csv.reader(self.new_dbf.splitlines()):
                row = line
                row_edit = re.sub(self.RegRemove,'', row[1])
                writer.writerow([row[0], row_edit])
                msg = data.getvalue()
                wx.CallAfter(Publisher().sendMessage, "update", msg)

我有一个按钮切换：

def checkBtnClick3(self, event):        
    self.DirQ.put(self.OpenDir.GetValue())
    self.new_dbfQ.put(self.new_dbf)
    self.RemoveQ.put(self.RegRemove.GetValue())                
    t = MyThread(self.DirQ, self.new_dbfQ, self.RemoveQ)
    t.setDaemon(True)
    t.start()

我是否需要在我的帧类上添加某种空闲函数来释放GUI？
