Comment créer une seconde fenêtre et comment interagir avec elle :

import java.awt.*;

PFrame f;
autreApplet s;

boolean drapeau;

void setup() {
  size(200, 200);
  s = new autreApplet();
  f = new PFrame(s);
  drapeau = false;
}

void draw() {
  background(255, 0, 0);
  if (s.temoin != drapeau) {
    drapeau = s.temoin;
  }
  if (drapeau) {
    fill(0, 255, 0);
  } else {
    noFill();
  }
  rect(50, 50, 100, 100);
}

void keyPressed() {
  if (key == 't') {
    f.setSize(600, 600);
  }
  if (key == ' ') {
    if (f.isShowing()) {
      f.setVisible(false);
    } else {
      f.setVisible(true);
    }
  }
}

void mousePressed() {
  if ((mouseX > 50) && (mouseX < 150) && (mouseY > 50) && (mouseY < 150)) {
    drapeau = !drapeau;
    s.temoin = !s.temoin;
  }
}

public class PFrame extends Frame {
  public PFrame(autreApplet autre) {
    setBounds(100, 100, 200, 200);
    add(autre);
    autre.init();
    setVisible(true);
  }
}

public class autreApplet extends PApplet {
  boolean temoin;

  public void setup() {
    size(200, 200);
    temoin = false;
  }

  public void draw() {
    background(0, 0, 255);
    if (temoin) {
      fill(0, 255, 0);
    } else {
      noFill();
    }
    rect(50, 50, 100, 100);
  }

  void mousePressed() {
    if ((mouseX > 50) && (mouseX < 150) && (mouseY > 50) && (mouseY < 150)) {
      temoin = !temoin;
    }
  }
}
