hi
you can check my code for fullscreen borderless (fullscreen non exclusive)
http://www.mediafire.com/file/zfkw03h3frbvh1p/SFML-2.4.2_borderless.rar
do not forget to backup your files first :)
example usage
window.create(sf::VideoMode(1920, 1080), "My Game", 16, contextSettings);
Well my modification did not solve any problem, my modification is an addtion to sfml features.
enum
{
None = 0, ///< No border / title bar (this flag and all others are mutually exclusive)
Titlebar = 1 << 0, ///< Title bar + fixed border
Resize = 1 << 1, ///< Title bar + resizable border + maximize button
Close = 1 << 2, ///< Title bar + close button
Fullscreen = 1 << 3, ///< Fullscreen mode (this flag and all others are mutually exclusive)
FullscreenBorderLess = 1 << 4, ///< Fullscreen mode borderless
Default = Titlebar | Resize | Close ///< Default window style
};
as soon as i find little time i create a branch. maybe in this afternoon
