我正在做一个项目，我有 3 个按钮。当用户按下它们时，会从 ini 文件中读取一些信息（输入编号、IP、端口和 pm），然后在我的类中声明的 InputDetected() 信号发出，发出此信号后，我想与服务器并将 pms 发送到服务器。为此，我在对话框类中创建了按钮。在 tcpclient 类中，我有 ConfigClass() 函数来读取 ini 文件，为了与服务器建立连接并向其发送 pms，我使用了 InputDetected() 信号，它的插槽是 Callrun() 函数。在 Callrun 函数中，我启动了 thread()，它的运行函数存在于“Mythread”类中。当我运行程序时，我得到了错误：'tcpclient' 没有命名类型（这个错误与 mythread.

如果有人可以帮助我解决此错误，我将不胜感激。另外，我不知道我是否正确使用了 qthread 类来与服务器建立连接。如果有人告诉我我的代码概念是否有问题，我将不胜感激
