Issue With Multiple Windows In Processing

I have a very simple sketch that opens multiple windows, like so:

void setup(){
  size(100,100);
  noLoop();
}
void keyPressed(){
  String[] args={"Secondary window!"};
  SecondWindow window=new SecondWindow();
  PApplet.runSketch(args, window);
}

class SecondWindow extends PApplet{
  void setup(){
    size(100,100);
    background(~0);
    noLoop();
  }
  void keyPressed(){
    exit();
  }
}

However, there is an issue: How can I close just child window? Pressing the [X] on the child window closes both the parent and child sketch, and the function exit() does the same.

Is there a method to close only the child applet? The PApplet documentation does not list any methods that seem to do this!

Thank you!

The surface variable gives you access to the underlying window. You can call surface.setVisble(false) to hide the window.

void setup(){
  size(100,100);
  noLoop();
}
void keyPressed(){
  String[] args={"Secondary window!"};
  SecondWindow window=new SecondWindow();
  PApplet.runSketch(args, window);
}

class SecondWindow extends PApplet{
  void setup(){
    size(100,100);
    background(~0);
    noLoop();
  }
  void keyPressed(){
    surface.setVisible(false);
  }
}
