Automatically resizing window with pictures to monitor resolution

[DzieckoBezZycia]

Hello!
I have a problem.

If I make windows (resolution 500x500) with one picture (500x500) i can resize it and picture resizes too. How can I make a window with resolution 1440x900 (resolution of my monitor), which is fullscreen. I want to send this program to another computer (with different resolution) and during making it fullscreen I want to make picture automatically resizes. How can I do it?

You can either scale the sprite itself to the window's size or manipulate the view. Since it's just one image, I suggest to scale the sprite itself.

Yes, but if someone for example has monitor with resolution 1366x768 and someone else 800x600, how can i know what int must I write?

entity.setScale(4.0f, 1.6f);
entity.setScale(a, b);

Of course I can get resolution of screen with

sf::VideoMode vm = sf::VideoMode::getDesktopMode();
sf::RenderWindow window( vm, "Title" );

but it's maybe the hardest way.

It's not an int, it is a float and there is a difference

Target Size / Initial Size = Scale
