How to apply for JWindow setAlwaysOnTop in Java? Where other JWindows are already also applied to setAlwaysOnTop

I have 3 layered window (like Gimp software). All my JWindow is assigned to setAlwaysOnTop for some display reasons with (xrandr --output VGA --left-of LVDS).

But I need one out of those three to be "the super main always on top, whatever it moves or get drags it always stay as super on top". How can I set that one?

Toolbox.java << he should be the very very super on top always for any drag or etc

public class Toolbox extends JWindow
{
  public Toolbox() {
    ..
    this.setVisible(true);
    this.setAlwaysOnTop(true);
  }
}

Layers.java < normal as it is

public class Layers extends JWindow
{
  public Layers() {
    ...
    this.setVisible(true);
    this.setAlwaysOnTop(true);
  }
}

Drawing.java < normal as it is

public class Drawing extends JWindow
{
  public Drawing() {
    ...
    this.setVisible(true);
    this.setAlwaysOnTop(true);
  }
}

$ java -jar MyGimp.jar
- first it launch Drawing
- secondly it launch Layers
- Thirdly at the end it launch Toolbox
- But in Display I see only Drawing and Layers sometimes, but I never see Toolbox

When I launch the Drawing window then all my toolbox and layers window gets behind. But I want Toolbox window forever stay on top unless I close it. How to do that?

Solution

The last component that is set to be on top overrides any previous components. What you do is just reset the Toolbox to be on top after you create Drawing.
