Single key press outside a sfml window?

[KKZiomek]

I recently wondered if there is a function in SFML that can detect if a key was pressed once but outside an event of a window. I would want do detevt this outside a sfml window. sf::isKeyPressed only detects if a key is held, but not pressed.

What do you mean under "detecting outside the window"?

[eXpl0it3r]

There isn't. Events are window based and sf::Keyboard does real-time checks.

Can anyone think of any way to turn those "id held" statements into single keypresses?

I did:

//Pseudocode
while isKeyPressed(Key)
{
        if not isKeyPressed(Key) break;
}

But this is not good, as other keys are not detected and program is delayed.

Can anyone think of better way?

You need to store the previous state of the key. Then compare it to the current state: if they are different, then the key is either pressed or released.
