where to #including QtObjects ? (Forward declaration)

U7Development

Hi !!..

I saw that could not possible to use forward declaration the way:

//MyHeader.h
class X{
class QPushButton * getMyButton();
};

//Source
#include "MyHeader.h"
#include <QPushButton> 
QPushButton * X::getMyButton(){
       return new QPushButton;
}

It gives me the error "Return type of out-of-line definition of X::getMyButton() differs from that in the declaration"

If I remove the "class" word and include the QPushButton directly on header, the problem goes away.... So this points me to a question...
Do I´m forced to #include all my QtObjects inside the header file ?... or is there any way that I can do forward declaration in Qt ?..

Thanks so much...

Hi
When use pointers to widgets, you can forward like

class QPushButton ; // forward

//MyHeader.h
class X{
QPushButton * getMyButton();
};
