Examples

  • // Click on the image to give it focus,
    // and then press any key.
    
    // Note: The rectangle in this example may 
    // flicker as the operating system may 
    // register a long key press as a repetition
    // of key presses.
    
    void draw() {
      if (keyPressed == true) {
        fill(0);
      } else {
        fill(255);
      }
      rect(25, 25, 50, 50);
    }
