先贴一段代码：(checkThread、myThread是我自己创建的线程)
checkThread *ckthread = new checkThread;
connect(ckthread, SIGNAL(notifymain(QString)), this, SLOT(testwjz(QString)));
ckthread->start();
myThread *bundlthread = new myThread;
bundlthread->start();
两个线程我都重写了他们的run函数。
void checkThread::run()
{
while(true)
{
sleep(3);
emit notifymain("This is the son thread");
}
exec();
}
void MainWindow::testwjz(QString s)
{
qDebug()<<s;
}
问题估计出在第二个线程：我先这样重写它的run函数的。
void myThread::run()
{
while(true)
{
qDebug()<<"Thread is running!";
sleep(3);
}
exec();
}
程序运行正常。
然后我改了一下：
void myThread::run()
{
BundlerApp::RunBundler();//调用了一个算法
exec();
}
然后出现错误
"This is the son thread"
"This is the son thread"
