constructor return type

I programming a code
example:

Code:

class MyWidget: public QWidget

{

public:

      MyWidget( QWidget *parent = 0, const  char *name =0)

};



MyWidget::MyWidget( QWidget *parent, const char *name)

              :QWidget( parent, name)

{

¡_¡_¡_¡_¡_¡_¡_¡_¡_¡_¡_¡_¡_¡_

¡_¡_¡_¡_¡_¡_¡_¡_¡_¡_¡_¡_

}

the compiler tell me that the
" ISO C++ forbids defining types within return Type
return type specification for constructor invalid"
but have some code, can pass the compile
why?
I know the construction don't need the return type!

It looks like maybe you forgot a semicolon after the declaration of MyWidget(). Also, perhaps you need a forward declaration for MyWidget, since you are trying to declare a pointer to one before it's fully defined. I think all you need to do is put:

Code:

class MyWidget;

before you start declaring your class.

thank you
the reason is the semicolor!
