Global Hotkeys on OS X

[xqbt]

I am trying to make use of global hotkeys in my C++ SFML program.

Specifically, I am trying to do that when the program is out of focus and invisible. The second is achievable by calling setVisible(false).

So, I have success using:

if (sf::Keyboard::isKeyPressed(sf::Keyboard::Left))

I just poll keyboard every 10 milliseconds and it works.
BUT it works only only on windows and linux.
Does not work on mac.
On mac, it works only when window is in focus.

Is there a workaround?
Could anyone please help me achieve the functionality?

What exactly are you trying to accomplish? A keylogger? Anyways, without looking into it - it is probably an intentional limitation of OSX.

No, not a keylogger Global hotkeys - unfold the program, do some action, stuff like that.

I am trying to use DDHotKey

But I simply do not understand where I embed the code and which callback function I have to pass. (I have almost no experience using cocoa or carbon). No basic understanding.

I thought maybe someone has done something like that before.

zsbzsb is right, SFML cannot do that for you. The thing is, on OS X you receive keyboard events only when the window is active.

Yeah, it seems to be that way. Anyway, thanks.
