mouseWheel on g4p window

Processing Libraries
1

Hi guys, I would translate a g4p label on g4p further window but i can’t do it. If I use the translate(x,y) function on main window it work fine but in another g4p window it doesn’t.
The function mouseWheel works only when the mouse is over the main window, my intent is to translate the label on window1.

This is the minimal code:

import g4p_controls.*;

GWindow window1;
GLabel label2; 

float ty = 0.0; // offset of Y axis traslation

 // -------------------------------------------------------
 
public void setup() {
  size(800, 600); // main window

  // create further window
  window1 = GWindow.getWindow(this, "Window title", 0, 0, 800, 600, JAVA2D);
  window1.noLoop();
  window1.setActionOnClose(G4P.KEEP_OPEN);
  window1.addDrawHandler(this, "win_draw1");
  window1.loop();

  // create the label that i wont to traslate
  label2 = new GLabel(window1, 80, 100, 80, 20);
  label2.setTextAlign(GAlign.CENTER, GAlign.MIDDLE);
  label2.setText("My label 2");
  label2.setOpaque(true);
} // end setup

 // -------------------------------------------------------

public void draw() {
  background(80);
  translate(0, ty); // affect in main window
  window1.background(60);
  window1.translate(0, ty); // affect in window1
} // end draw

 // -------------------------------------------------------

void mouseWheel(MouseEvent event) {
  ty = ty + event.getCount(); // amount of traslating
  println("ty: " + ty);
} // end mouseWheel

Thank’s in advance for those who help me…

sorry, i just want show a other example, where
@quark solved my 2 window question,
and based on this i added 2 slider where mouse wheel works,
incl separate event handlers.
hope you can use any of this.

better help might come from quark.
