QTCP多线程问题 [复制链接]

<DIV id=read_tpc mb10?>先贴代码

}
void TERMINAL_THREAD::write_tcp(QString str){  
write_string=str;

在主线程里面发一个信号调用write_tcp，报QSocketNotifier: socket notifiers cannot be enabled from another thread

请问大神如何解决

在构造函数中加上 moveToThread(this);试试

效果一样，问题很明显，就是想不到办法解决

connect(send_write,SIGNAL(write_send(QString)),this,SLOT(write_tcp(QString)),Qt::DirectConnection);
这个放到主线程里进行连接。
你现在的写法是错的。
如果采用二楼的，就要把RUN里的改到类里去，在类创建后再从创建线程中移到另一个线程。
而且你主要是从主线程发送信号，那么绑定最好是在主线程绑定。

我等等试试，现在我解决是重写了Qtcpsocket，在run下面new一个，要发的数据直接传到tcpsocket下再发，这个倒行的通
