Making always-on-top nodes

Question

hi,
im using a text box to accept text to display,i do it by making the textbox visible when i want to enter text and set visible false when text is entered..its can be set to visible again by a button..
things is after after a few nodes have been displayed..the textbox since it was declared before them,when its made visible again,it appears "under" the nodes created.
is there a way to make the text box come up always on top ???

On the static scene it is possible to use toFront() and toBack() node's functions
Like this:
import javafx.stage.*;
import javafx.scene.*;
import javafx.scene.paint.*;
import javafx.scene.shape.*;
import javafx.scene.control.*;
var nodes = for(color in [Color.GREEN, Color.BLUE, Color.RED])Circle{
    fill: color
    radius: 50
var n = 0;
Stage {
    title: "Application title"
    scene: Scene {
        width: 300
        height: 300
        content: [
            Button{
                text: "To Front"
                action: function () { nodes[n].toFront(); n = (n + 1) mod sizeof nodes  }
            Group{
                translateX: 150
                translateY: 150
                content: nodes
}
