Detailed Description

Give access to the real-time state of the keyboard.

sf::Keyboard provides an interface to the state of the keyboard.

This namespace allows users to query the keyboard state at any time and directly, without having to deal with a window and its events. Compared to the KeyPressed and KeyReleased events, sf::Keyboard can retrieve the state of a key at any time (you don't need to store and update a boolean on your side in order to know if a key is pressed or released), and you always get the real state of the keyboard, even if keys are pressed or released when your window is out of focus and no event is triggered.

Usage example:

if (sf::Keyboard::isKeyPressed(sf::Keyboard::Key::Left))
{
    // move left...
}
else if (sf::Keyboard::isKeyPressed(sf::Keyboard::Key::Right))
{
    // move right...
}
else if (sf::Keyboard::isKeyPressed(sf::Keyboard::Key::Escape))
{
    // quit...
}
else if (sf::Keyboard::isKeyPressed(sf::Keyboard::Scan::Grave))
{
    // open in-game command line (if it's not already open)
}

Function Documentation

delocalize()

SFML_WINDOW_API Scancode sf::Keyboard::delocalize ( Key key )

nodiscard

Identify the physical key corresponding to a logical one.

Parameters

key	Key to "delocalize"

Returns

The scancode corresponding to the key under the current keyboard layout used by the operating system, or sf::Keyboard::Scan::Unknown when the key cannot be mapped to a sf::Keyboard::Scancode.

See also

localize

getDescription()

SFML_WINDOW_API String sf::Keyboard::getDescription ( Scancode code )

nodiscard

Provide a string representation for a given scancode.

The returned string is a short, non-technical description of the key represented with the given scancode. Most effectively used in user interfaces, as the description for the key takes the users keyboard layout into consideration.

Warning

The result is OS-dependent: for example, sf::Keyboard::Scan::LSystem is "Left Meta" on Linux, "Left Windows" on Windows and "Left Command" on macOS.

The current keyboard layout set by the operating system is used to interpret the scancode: for example, sf::Keyboard::Key::Semicolon is mapped to ";" for layout and to "é" for others.

Parameters

code	Scancode to check

Returns

The localized description of the code

isKeyPressed() [1/2]

SFML_WINDOW_API bool sf::Keyboard::isKeyPressed ( Key key )

nodiscard

Check if a key is pressed.

Parameters

key	Key to check

Returns

True if the key is pressed, false otherwise

isKeyPressed() [2/2]

SFML_WINDOW_API bool sf::Keyboard::isKeyPressed ( Scancode code )

nodiscard

Check if a key is pressed.

Parameters

code	Scancode to check

Returns

True if the physical key is pressed, false otherwise

localize()

SFML_WINDOW_API Key sf::Keyboard::localize ( Scancode code )

nodiscard

Localize a physical key to a logical one.

Parameters

code	Scancode to localize

Returns

The key corresponding to the scancode under the current keyboard layout used by the operating system, or sf::Keyboard::Key::Unknown when the scancode cannot be mapped to a Key.

delocalize

setVirtualKeyboardVisible()

SFML_WINDOW_API void sf::Keyboard::setVirtualKeyboardVisible

(

bool

visible

)

Show or hide the virtual keyboard.

Warning

The virtual keyboard is not supported on all systems. It will typically be implemented on mobile OSes (Android, iOS) but not on desktop OSes (Windows, Linux, ...).

If the virtual keyboard is not available, this function does nothing.

Parameters

visible

True to show, false to hide
