now I add another problem I've already added yesterday but in another thread.. It's almost the same thing like with the boolean-variable..

if I want to program a resizable window with two napplets, the actual width and height isn't the same in another napplet.. so is there a possibility to program this? I've worked with a main tab that is resizable and a fixed napplet that has got a very big width and a constat height, so that if I resize the window you can't see that the napplet hasn't been resized.. but with a third napplet, it isn't possible anymore.
And I would like to make the third napplet resizable, but if I set frame.setResizable(true) in the void setup of the third tab, there's an error.. what I want to program in fact is similiar to geogebra.. there are three frames, the upper in the height fixed in the width resizable with the main frame. the second frame on the left side is resizable in the width and fixed in the height (height of the main frame - height of the upper frame).. Is there an easy possibility to program that? or a more difficult possibility? I'm stuck with it..

About the first issue, here's a sketch I wrote.  The black bar at the top is the "TopPane" napplet, and clicking on it will change the color of the main sketch's background.  It works fine for me without needing a resize.

Code:

import napplet.*;

NAppletManager nappletManager;

int backColor = 255;

void setup() {
  size(400, 400);
  nappletManager = new NAppletManager(this);
  
  nappletManager.createEmbeddedNApplet("TopPane", 0, 0);
}

void draw() {
  background(backColor);
} 

Code:

public class TopPane extends NApplet {

  void setup() {
    size(parentPApplet.width, 100);
  }

  void draw() {
    background(0);
  }
  
  void mouseClicked() {
    if (backColor==255);
	backColor = 100;
    else backColor = 255;
  }
} 

I'm still working on the second issue, so I'll try to get back to you on that soon.

Not sure why missed the release of this library. Really great. this is useful for a lot of things
