1Qter豆
请问各位 我是原来做MCU开发的 基本没有C++经验 现在学习QT开发 使用的环境是Windows+QT5.11 打算给单片机做个云端自动升级服务 ，现在程序遇到了技术问题 希望大家帮忙解决 谢谢了
void MyWidget::processNewConnection()
{
/* 每进来一次 创建一个这样的对象 然后在断开连接的时候 记得销毁都可以了 但是假如程序异常退出呢 这个空间十分释放？*/
/* 这个其实多线程并发处理了 只是不是线程 而是类的实例对象 */
mypCurTcpSocket = myTcpServer.nextPendingConnection();
ptcpClient.append(mypCurTcpSocket);
/* 绑定信号和槽函数 */
connect(mypCurTcpSocket, SIGNAL(disconnected()), this, SLOT(disconnectedFromHost()));
connect(mypCurTcpSocket, SIGNAL(readyRead()), this, SLOT(ReadData()));
ui->textEdit->append("客户端IP+PORT: ");
}
上面的 connect 函数使用 编译报错 。
