Hello,
I have a compilation problem about namespaces:

I have a namespace X in which I declera a type definition:

In X.h file i write:

namespace X {
typedef unsigned int WindowHandle_t;
}

In a class which is in a different namespace ( Y ), I must use the type
definition I declared in namespace X.
MyClass.h file:

Y::MyClass {
....
private:
X::WindowHandle_t handle;
....
}

And the code doesn't compile. I should forward declare this handle type
definition but forward decleration is the same as writing the same
thing that I wrote in X.h file. When I write

In MyClass.h file :

namespace X {
typedef unsigned int WindowHandle_t;
}

Y::MyClass {
....
private:
X::WindowHandle_t handle;
....
}

The code compiles. But as I stated, I do not want to write same type
definition twice in a code. Do you have any suggestions?

Thanks...

I included it after MyClass.h. There is no way to include it before
MyClass.h .
