Centering the game window.
« on: March 07, 2014, 04:01:33 pm »
SFML basically centers the window when it is created.
but it doesn't consider Windows taskbar and also the game window's border size.
the border size is negligible but, the taskbar is a bit annoying.
here's some pictures for the explanation.





I want to set the window like the second image.
so, how can I get the taskbar's position, size and a window's border size?
any advice will be appreciated. thank you :)

Have a look at the following functions:
sf::Window::setPosition()
sf::VideoMode::getDesktopMode()

You can't get the taskbar, menu or border size via SFML.

unfortunately, they were not useful.
this is the same as the initial position.

sf::Window window(...);
auto desktop = sf::VideoMode::getDesktopMode();
window.setPosition(desktop.width/2 - window.getSize().x/2, desktop.height/2 - window.getSize().y/2);

Yes, of course; after all you're setting the position to the center of the screen, and not to the center of the screen without taskbar.

You have to account for the latter manually (either by hardcoding a fixed value or calling WinAPI functions).

ok, thanks for the replies. :)
i don't think everyone put the taskbar on the bottom.
so, i'd better to use some WinAPI functions.
