## Detailed Description

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

sf::Keyboard provides an interface to the state of the keyboard. It only contains static functions (a single keyboard is assumed), so it's not meant to be instantiated.

This class 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::Left))
{
// move left...
}
else if (sf::Keyboard::isKeyPressed(sf::Keyboard::Right))
{
// move right...
}
else if (sf::Keyboard::isKeyPressed(sf::Keyboard::Escape))
{
// quit...
}

## Member Function Documentation

## ◆ isKeyPressed()

static bool sf::Keyboard::isKeyPressed | ( | Key | key | ) |
| static

Check if a key is pressed.

Parameters

  key | Key to check

Returns
  True if the key is pressed, false otherwise

## ◆ setVirtualKeyboardVisible()

static void sf::Keyboard::setVirtualKeyboardVisible | ( | bool | visible | ) |
| static

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
