How to let intellisense knows about non-self contain symbols in header files that

[jronald]

As below, b.h references class A in a.h, but b.h doesn't include a.h directly but indirectly instead.
The code can be built successfully.
The problem is tht Qt Creator shows a warning for class A in b.h, for it doesn't know class A, and navigation to class A failed.
How to fix the problem without adding #include <path\to\a.h> in b.h?

a.h

class A
{
    ...
}

b.h

void test(A a);

b.cpp

#include "a.h"
#include "b.h"

void test(A a)
{
   ...
}

Yes, that looks like correct behaviour to me.

I would not expect you would need a path to .a.h, b.cpp manages with #include "a.h". I would expect b.h to include a.h.

You could put class A; before void test(A a); into b.h, so that it knows A is an external class, but I don't think it would help much.

I don't see how you expect b.h to know about class A, or how to navigate to it etc., if you're not prepared to include a.h into it.

Visual Studio is smart enough to know class A in b.h in this case.

But I think #include "a.h" in b.h is the essential way.
