QT 延时函数设置

QT 的延时函数分为非阻塞延时 和 阻塞型延时

非阻塞延时：

void GreenPass3::delaymsec(int msec)
{
    QTime dieTime = QTime::currentTime().addMSecs(msec);

while( QTime::currentTime() < dieTime )

QCoreApplication::processEvents(QEventLoop::AllEvents, 100);
}

阻塞延时：

void GreenPass3::delaymsec(int msec)
{

QTime n=QTime::currentTime();

QTime now;
    do{
      now=QTime::currentTime();
    }while (n.msecsTo(now)<=msec);

}
