java - Layout using the transformed bounds -

i have scaled node in pane. layout of pane take account bounds without transformation. want take account transformed bounds.

for example :

and code :

import javafx.application.application; import javafx.geometry.pos; import javafx.scene.scene; import javafx.scene.control.label; import javafx.scene.layout.hbox; import javafx.scene.layout.vbox; import javafx.scene.shape.circle; import javafx.scene.transform.scale; import javafx.scene.transform.translate; import javafx.stage.stage;  public class hboxapp extends application {     public static void main(string[] args) {         launch(args);     }      @override         public void start(stage stage) throws exception {             double scale = 0.75;              hbox box1 = createbox();             box1.getchildren().add(new circle(20));             box1.getchildren().add(new label("test without scale"));              hbox box2 = createbox();             circle c2 = new circle(20);             c2.setscalex(scale);             c2.setscaley(scale);             box2.getchildren().add(c2);             box2.getchildren().add(new label("test setscalex/y methods"));              hbox box3 = createbox();             circle c3 = new circle(20);             c3.gettransforms().add(new scale(scale, scale));             box3.getchildren().add(c3);             box3.getchildren().add(new label("test scale transform"));              hbox box4 = createbox();             circle c4 = new circle(20);             c4.gettransforms().addall(new scale(scale, scale), new translate(-20*(1-scale), 0));             box4.getchildren().add(c4);             box4.getchildren().add(new label("test scale , translate transform"));              hbox box5 = createbox();             box5.getchildren().add(new circle(20 * scale));             box5.getchildren().add(new label("my goal"));              vbox vbox = new vbox(10);             vbox.getchildren().addall(box1, box2, box4, box5);             stage.setscene(new scene(vbox, 300, 200));             stage.show();         }      private hbox createbox() {         hbox box = new hbox(5);         box.setalignment(pos.center_left);         return box;     } } 

a solution apply translations on circle , on label, way seems hard doing simple thing, , using pane(hbox) seems more painful using basic group hardcoded layout.

i found answer in post javafx1.2: understanding bounds :

if want layoutbounds match node's physical bounds (including effects, clip, , transforms) wrap in group (ex. if want node scale on mouse-over , want neighbors scoot on make room magnified node).

so solving problem, wrote :

... hbox box5 = createbox(); circle c5 = new circle(20); c5.setscalex(scale); c5.setscaley(scale); box5.getchildren().add(new group(c5)); box5.getchildren().add(new label("test scale transform , group")); ... 

and got expected result.
