View does not seem to be working?

[DasOhmoff San]

Hello, I am trying to find out how exactly View is working and I cannot seem to figure it out.
I looked at this page: https://www.sfml-dev.org/tutorials/2.5/graphics-view.php

And wrote some test code:

#include <SFML/Graphics.hpp>
#include <SFML/Window.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(1280, 720), "test");
    sf::Event event;

    sf::View view;
    view.setViewport(sf::FloatRect(0.f, 0.f, 0.5f, 1.f));
    window.setView(view);

    sf::RectangleShape rs; rs.setSize({1280, 720});

    while(window.isOpen())
    {
        while(window.pollEvent(event))
            if(event.type == sf::Event::Closed)
                window.close();

        window.clear();
        window.draw(rs);
        window.display();
    }

    return 0;
}
 

The output:


What I expected:


Similar to this in the doc:


Can someone please explain what is happening?
