Title: sf::RenderWindow responds to clicks, on background ...
Post by: Léandre on July 26, 2017, 02:23:00 pm

Hi,

I'm not really new with sfml, but was using CSFML, well now I'm learning C++ and doin pretty well,
So I'm creating a tiny game, where I need to handle mouse position, my main problem is that, even if I'm focused
in a Terminal of other software, the window still responds in background, so I can click on the sfml window, while being in my C++ code for example.
Hum, is there any way to avoid this ? Because I'm using isKeyPressed and isMousePressed so maybe witch the events ?

Best regards,
Léandre

Nevermind, I've found the LostFocus event

LostFocus and GainedFocus can solve your problem but you will have to track the focus state to know whether it's currently in focus or not (it would only need a simple boolean, of course).

However, and especially since you're using real-time states, you may also be interested in hasFocus (https://www.sfml-dev.org/documentation/2.4.2/classsf_1_1Window.php#ac4dce670f07c5039a732ba0903ce3a77), which can inform you of the current state of focus.

e.g.

if (window.hasFocus())
{
    if (isKeyPressed(sf::Keyboard::Up))
        moveUp();
    if (isKeyPressed(sf::Keyboard::Down))
        moveDown();
    // etc.
}
