Question

I m using SFML for input system in my application.

size_t WindowHandle;
WindowHandle = ...; // Here I get the handler

sf::Window InputWindow(WindowHandle);
const sf::Input *InputHandle = &InputWindow.GetInput();  // [x] Error

At the last lines I have to get reference for the input system.

Here is declaration of GetInput from documentation:

const Input & sf::Window::GetInput () const

The problem is:

>invalid conversion from ‘const sf::Input*’ to ‘sf::Input*’

What s wrong?

Answer 1

Is there a special reason why you want to have a pointer rather than a reference? If not, you could try this:

const sf::Input & InputHandle = InputWindow.GetInput();

This will return you a reference to your Input handle.

Btw, this worked for me:

const int& test(int& i)
{
  return i;  
}

int main()
{
   int i = 4;

   const int* j = &test(i);

   cout << *j << endl;
   return 0;
}

Output : 4

Don t know why your compiler doesn t want you to point the reference.
