Swingbuilder - Application Location Centralization

I am creating an application using Griffon-> SwingBuilder. I would like to be able to center the application on the desktop.

I know that we have the argument "location: [x, y]", which we can provide when creating the application. Is there any way to access the properties of the desktop to calculate the center?

For various reasons, you cannot do this inline. Here is one way to focus.

import java.awt.*
import groovy.swing.*

sb = new SwingBuilder()
sb.build {
  f = frame(pack:true) {
      label "<html>" + (("This is a very long label."*3) + "<BR>")*5
  }
  Point cp = GraphicsEnvironment.localGraphicsEnvironment.centerPoint
  f.location = new Point((int)(cp.x - f.width), (int) (cp.y - f.height))
  f.show()
}

, , , node . , :

  frame(show:true) 
  {
      label "<html>" + (("This is a very long label."*3) + "<BR>")*5
      current.pack()
      Point cp = GraphicsEnvironment.localGraphicsEnvironment.centerPoint
      current.location = new Point((int)(cp.x -current.width/2), (int)(cp.y - current.height/2))
  }

( - node).
