所有的数据处理都应该通过异步进行

1. 定义信号
   

   # 自定义信号源
   class QCustomSignal(QObject):signal_update_table = Signal(list)signal_get_token = Signal(str)signal_send_mq = Signal()

2. 处理函数
   

       @Slot()def handle_search(self):def thread_function():user_info = get_user_info(token=self.token, username=self.lineEdit.text())# 发出信号custom_signal.signal_update_table.emit(user_info)# 异步访问API并发出渲染信号Thread(target=thread_function).start()# 绑定信号的处理函数custom_signal.signal_update_table.connect(self.handle_search_render)

3. 渲染函数
   

       @Slot(list)def handle_search_render(self, user_info):self.user_info = user_info# QTableWidget句柄widget: QTableWidget = self.tableWidget# 设置行数widget.setRowCount(len(user_info))# 设置列数widget.setColumnCount(5)# 设置表头widget.setHorizontalHeaderLabels(["姓名", "组织", "手机号码", "操作", "检测"])# 设置表头宽度自适应widget.horizontalHeader().setSectionResizeMode(QHeaderView.Stretch)widget.horizontalHeader().setSectionResizeMode(0, QHeaderView.Fixed)widget.horizontalHeader().setSectionResizeMode(2, QHeaderView.Fixed)widget.horizontalHeader().setSectionResizeMode(3, QHeaderView.Fixed)widget.horizontalHeader().setSectionResizeMode(4, QHeaderView.Fixed)
