Creating a fullscreen window doesn't hide the taskbar

[SuperGabry64]

Creating a fullscreen window doesn't hide the taskbar, but prevents the window from overlapping on it.

The code is this:

(click to show/hide)

#include <SFML/Window.hpp>
#include <SFML/Graphics.hpp>
#include <SFML/System/Vector2.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(320, 200), "Game", sf::Style::Fullscreen);
    auto desktop = sf::VideoMode::getDesktopMode();
    window.setPosition(sf::Vector2i(desktop.width / 2 - window.getSize().x / 2, desktop.height / 2 - window.getSize().y / 2));
    sf::View defView(window.getView());
   
    // run the program as long as the window is open
    while (window.isOpen())
    {
        // check all the window's events that were triggered since the last iteration of the loop
        sf::Event event;
        while (window.pollEvent(event))
        {
            // "close requested" event: we close the window
            if (event.type == sf::Event::Closed)
                window.close();
        }
    }

    return 0;
}

And the result is this:

OS: Windows 10 64bit
GPU: GeForce GTX 1050

Is 320 200 a supported fullscreen resolution by your screen?
Can check if it's in getFullscreenModes or with isValid https://www.sfml-dev.org/documentation/2.5.1/classsf_1_1VideoMode.php#ad5e04c044b0925523c75ecb173d2129a

Yes, it's supported, and because if it's not supported it will tell me when I start the game that the video mode is not valid and it will switch to the desktop mode. However, I switched to a 640x400 mode, which is supported too

So did you add the getFullscreenModes and validated it?

Just because something happens, doesn't mean it's a supported fullscreen mode.

In the end, there's little SFML can do in that regards. We just tell the OS that we want a fullscreen window and when the OS does something else, we don't really have the control over it.
