This program just serve to move rectangle or circle with keyboard or mouse.
When all the program is in the main function I don't have any probleme but I want use subroutine and class in the future when I will be training but I have the following error ! error C2248
After search I think the probleme come from function 'sf::RenderWindow' but again beginner I don't understand how get arround the problem.
Thanks to help! :)

Answer 1

The problem is as #Jepessen mentioned you basically have a return type of sf::RenderWindow on your declaration, and your parameter is of type Pointer sf::RenderWindow:
sf::RenderWindow fenetre(sf::RenderWindow*);
And then when you define the function, you are returning void, and your parameter is a Reference sf::RenderWindow:
void fenetre(sf::RenderWindow &window)
{
// Code
}
To Fix this, make the return type of the declaration of fenetre void, since you are not actually returning a value at all, and make your parameter Reference to sf::RenderWindow:
// Declaration, on top of your program
void fenetre(sf::RenderWindow&);
// Definition, at the bottom
void fenetre(sf::RenderWindow &window)
{
// Code
}
