signal and slots

[vermarajeev]

Hello All,

//.h
class A
{
     Q_OBJECT
     public:
           A(){}
     public slots:
           #ifdef SOMEMACRO
                  void slotA();
           #endif    
};
  //.cpp
#ifdef SOMEMACRO
      void A::slotA()
       {
                //..
       }
#endif

//.h
class A
{
     Q_OBJECT
     public:
           A(){}
     public slots:
           #ifdef SOMEMACRO
                  void slotA();
           #endif    
};
  //.cpp
#ifdef SOMEMACRO
      void A::slotA()
       {
                //..
       }
#endif

If SOMEMACRO is "NOT DEFINED" will the above code compile?
In my case it doesn't compile. Why?
Is the moc_A.cpp file created before preprocessors being parsed by the compiler?

Thanks
