Views vs window confusion

[rogeriodec]

I have this single code...

#include <SFML/Graphics.hpp>

#define windowWidth  600
#define windowHeight 300

int main()
{
   sf::RenderWindow window(sf::VideoMode(windowWidth, windowHeight), "SFML Views");

   sf::View view(sf::FloatRect(0,0, windowWidth, windowHeight));
   view.zoom(2);
   window.setView(view);


   sf::RectangleShape back (sf::Vector2f(windowWidth, windowHeight));
   back.setFillColor(sf::Color::White);

   sf::RectangleShape rect (sf::Vector2f(200, 100));
   rect.setFillColor(sf::Color::Red);
   rect.setPosition(windowWidth - rect.getSize().x, windowHeight - rect.getSize().y); // position in the lower right corner

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

        window.clear();
        window.draw(back);
        window.draw(rect);
        window.display();
    }

    return 0;
}

...which might position the red rectangle in the lower right corner of the window.



However, when I zoom the view in (as in the code), it obviously moves along with the entire window.
I have some doubts:

   

• To correct the positioning of the red rectangle and place it in the lower right corner of the global window, I currently have to do some calculations considering the zoom factor, original rectangle size, etc. Is there any easier way to position this rectangle in the lower-right corner of the global window?
• How do I prevent some objects from being resized by the zoom of the view?
• What do I have to do to have multiple active views in the same window?

So what's your final goal?

Did you read and understand the view tutorial?

[rogeriodec]

Yes, I read. But since I'm a beginner in sfml, I still have not got the whole logic of the thing. And not always this tutorial is so understandable for beginners.
I've also watched several tutorial videos on youtube that are expanding my understanding of sfml.
But sometimes a simple, but less laconic answer can help.
In any case, I had the opportunity to have this support in StackOverflow and now I know how to solve it.
