import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class PasswordBoxSample extends Application {

    public static void main(String[] args) {
        launch(args);
    }

    private Parent getContent() {

        VBox list = new VBox();
        Pane pane=new Pane();
        TextField box = new TextField();
        box.setText("TextTextText");
        box.setFocusTraversable(false);
        box.setPrefHeight(300);
        pane.getChildren().add(box);
        list.getChildren().addAll(pane);
        return list;
    }

    public void start(Stage stage) {
        stage.setX(100);
        stage.setY(100);
        Scene scene = new Scene(getContent());
        stage.setScene(scene);
        stage.show();
