高手求助，QT多线程问题 [复制链接]

        我在编译QT2多线程的程序时出现如下错误
moc_ReceiveMovieThread.cpp: In member function `virtual void
   ReceiveMovieThread::initMetaObject()':
moc_ReceiveMovieThread.cpp:33: no method `QThread::className'
moc_ReceiveMovieThread.cpp: In static member function `static QMetaObject*
   ReceiveMovieThread::staticMetaObject()':
moc_ReceiveMovieThread.cpp:56: no method `QThread::staticMetaObject'
make: *** [moc_ReceiveMovieThread.o] Error 1

moc_ReceiveMovieThread.cpp:33:
if ( qstrcmp(QThread::className(), "QThread") != 0 )

moc_ReceiveMovieThread.cpp:56:
(void) QThread::staticMetaObject();

哪位高手能帮我看一下，到底是什么原因啊！
谢谢了！

把你创建多线程相关源代码贴出来吧

很可能是你的.h文件中的定义或写法有问题, 仔细检查一下

附件在下面希望高手帮我看一下

这种问题你可以试下：
make clean 后，再重新编译下

我的印象中, 从两个QObject的子类继承会有问题, 不知道是不是这个原因.
建议分成两个类来写

非常感谢大家的帮助！
问题已经解决了
我把类的声明
   class ReceiveMovieThread: public QThread, public QWidget
换成
   class ReceiveMovieThread: public QWidget, public QThread
就能编译通过了！
不知道这是为什么！！！
