菜鸟求助，EMIT Error后对应槽没有激发？

[weixin_38063369]

程序中，设定机制connect(firstServer,  SIGNAL(error(QAbstractSocket::SocketError)), this, SLOT(connectToSeconed(QAbstractSocket::SocketError )));在连接firstServer过程( connectToFirst() )中，想连接一秒后自动提示连接不上，转为连接secondServer ( connectToSeconed() ) ,实现如下{firstServer->connectToHost(firstIP,  firstPort, QIODevice::ReadWrite);if(!firstServer->waitForConnected(1000))      emit firstServer->error();return;}请问为何connectToSeconed(QAbstractSocket::SocketError ) 不会被激发呢？
