keyReleased() / Reference / Processing.org

Name

keyReleased()

Description

The keyReleased() function is called once every time a key is released. The key that was released will be stored in the key variable. See key and keyCode for more information.

Mouse and keyboard events only work when a program has draw(). Without draw(), the code is only run once and then stops listening for events.

Examples

// Click on the image to give it focus,
// and then press any key.

int value = 0;

void draw() {
  fill(value);
  rect(25, 25, 50, 50);
}

void keyReleased() {
  if (value == 0) {
    value = 255;
  } else {
    value = 0;
  }
}
