how to properly intialize static const user defined types?

class MyClass
{
   public:
   static const sf::Vector2f defaultPos = sf::Vector2f(WINDOW_HEIGHT/GAMEOBJECT_HEIGHT,WINDOW_WIDTH/GAMEOBJECT_WIDTH); //error
    
};

Line 4: You can't initialize a static const with a function call.

If you remove the const, you can initialize it where you initialize any globals:

  MyClass::defaultPos = sf::Vector2f (WINDOW_HEIGHT/GAMEOBJECT_HEIGHT, WINDOW_WIDTH/GAMEOBJECT_WIDTH);

Looks like it's not a constant expression, because of the function call:

Constant static members

If a static data member of integral or enumeration type is declared const (and not volatile), it can be initialized with a initializer in which every expression is a constant expression, right inside the class definition:
