hi

is there away to call one window from other window ?

```auto
void setup() {
  String[] args = {"TwoFrameTest"};
  SecondApplet sa = new SecondApplet();
  PApplet.runSketch(args, sa);
}

void settings() {  
  size(300, 100);
}

void draw() {
  background(0);
  fill(255);
  text("Hello world!", 50, 40);
}   

public class SecondApplet extends PApplet {

  public void settings() {
    size(200, 200);
  }

  public void draw() {
    background(255);
    fill(0);  
    text("Hello world!", 50, 40);
  }
}

```

You could try the G4P library.

> Creating a new GWindow is straightforward enough but to launch a new program (sketch) and passing values form an existing sketch is a different problem altogether. Are you using the GUI Builder tool to create your initial GUI?
