在加入信号与槽以后，只要加入Q_OBJECT宏，就会出现如下错误：
mainwindow.obj : error LNK2001: unresolved external symbol "public: virtual bool __thiscall MainWindow::qt_property(int,int,class QVariant *)" (?qt_property@MainWindow@@UAE_NHHPAVQVariant@@@Z)
mainwindow.obj : error LNK2001: unresolved external symbol "public: virtual bool __thiscall MainWindow::qt_emit(int,struct QUObject *)" (?qt_emit@MainWindow@@UAE_NHPAUQUObject@@@Z)

Debug/TSRT.exe : fatal error LNK1120: 6 unresolved externals
就是说信号与槽怎么都连不上，我的QT版本是3.2.1
源代码如下：

#define MAINWINDOW_H

各位大侠帮忙看看吧，多谢了！
