Stage.setX doesn't work before stage.show is called?

Question

I would like to set the position of a new window before its made visible. stage.setX and stage.setY don't have any effect before stage.show is called. Is it possible to set the window position before its made visible? If so, how?

Answer 1

This works for me. Can you post an example where it fails?
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.layout.VBox;
import javafx.stage.Modality;
import javafx.stage.Stage;
public class HelloWorld extends Application {
  @Override
  public void start(final Stage primaryStage) {
    final VBox root = new VBox();
    root.setAlignment(Pos.CENTER);
    final Button button = new Button("Press me");
    button.setOnAction(new EventHandler<ActionEvent>() {
      @Override
      public void handle(ActionEvent event) {
        final Stage stage = new Stage();
        final VBox root = new VBox();
        root.getChildren().add(new Label("Thanks"));
        final Scene scene = new Scene(root, 200, 125);
        stage.setScene(scene);
        stage.initOwner(primaryStage);
        stage.initModality(Modality.APPLICATION_MODAL);
        stage.setX(100);
        stage.setY(100);
        stage.show();
    root.getChildren().add(button);
    final Scene scene = new Scene(root, 350, 200);
    primaryStage.setScene(scene);
    primaryStage.setX(200);
    primaryStage.setY(200);
    primaryStage.show();
  public static void main(String[] args) {
    launch(args);
}
