QTcpSocket和插槽和信号的运行时错误

Question

我正在编写一些代码来建立TCP套接字,我在尝试设置我想要收听的信号时遇到错误.

代码是:

connection = new QTcpSocket(this);

connect(connection,SLOT(connected()),this,SIGNAL(onConnection()));
connect(connection,SLOT(readyRead()),this,SIGNAL(gotData()));
connect(connection,SLOT(disconnected()),this,SIGNAL(onConnection()));

我得到的错误是:

 Object::connect: Attempt to bind non-signal QTcpSocket::connected()
 Object::connect: Attempt to bind non-signal QTcpSocket::readyRead()
 Object::connect: Attempt to bind non-signal QTcpSocket::disconnected()

我找不到其他有同样问题的人.我在想,我正在做的事情是愚蠢的.我在该计划中的其他信号正在发挥作用.

您使用QObject :: connect方法的方式很糟糕!

你必须使用这样的连接方法:

connection = new QTcpSocket(this);

connect(connection,SIGNAL(connected()),this,SLOT(onConnection()));
connect(connection,SIGNAL(readyRead()),this,SLOT(gotData()));
connect(connection,SIGNAL(disconnected()),this,SLOT(onConnection()));
