[提问]Q_PROPERTY宏无法使用，报出'xxx' was not declared in this scope [复制链接]

我使用的是Qt SDK for Windows*，QT版本是4.7.0，MinGW编译
查看assistant介绍Q_PROPERTY使用方法后编写测试类：

#ifndef BASEOBJECT_H
#define BASEOBJECT_H

#include <QObject>

public BaseObject : public QObject
{
Q_OBJECT
Q_PROPERTY(double weight READ weight WRITE setWeight)
public:
explicit BaseObject(QObject *parent = 0);
~BaseObject();
};

#endif

编译的时候，报出错误：
debug\moc_baseobject.cpp: In member function 'virtual int WorldView::qt_metacall(QMetaObject::Call, int, void**)':
debug\moc_baseobject.cpp:75: error: 'weight' was not declared in this scope
debug\moc_baseobject.cpp:78: error: 'setWeight' was not declared in this scope

mingw32-make[1]: Leaving directory `E:/CodeSource/QWorldEngine-build-desktop'
mingw32-make: Leaving directory `E:/CodeSource/QWorldEngine-build-desktop'
mingw32-make[1]: *** [debug/moc_baseobject.o] Error 1
mingw32-make: *** [debug] Error 2

是环境设置问题还是其它？如果我删除Q_PROPERTY这行代码编译就没有问题。请问有人知道错误原因吗？

悲剧。。。提交的时候报了错，原来提交了这么多。。。

拜托管理员帮忙删除一下多余的吧，谢谢了。。。

weight, setWeight 这两个函数你还没定义
