Re: Problem understanding some warnings

Alessandro,

For the 402, are you sure you're correctly including the header file where
the CartridgeWidget class is defined in your swig interface file? If you
use the pImpl idiom for eg that means including the _Impl.hpp file in
addition to the .hpp one.

For the 516, just %ignore the specific overload you want to discard.

eg, your .i file could look like this:

```
#ifndef MYCLASS_I
#define MYCLASS_I

%{
  #include "MyClass.hpp"
%}

#ifdef SWIGJAVA
  %ignore mynamespace::MyClass::GetPixels() const;
#endif

%include <MyClass.hpp>

#endif // MYCLASS_I
```

(Disclaimer: I am just a swig user like you and the above might not be the
most correct advice...)

Best,
