how to switching scenes in javafx (NO FXML)

I ask for your understanding, I am a beginner;)
I'm trying to build a simple application using JavaFX. The problem is that when I open the window the first time it goes well, but if I want to change the scene it throws an error...
Exception in thread "JavaFX Application Thread"
java.lang.IllegalArgumentException:
AnchorPane#1809546[styleClass=root]is already set as root of another
scene#
Main class
public class Main extends Application{
//private Stage primaryStage;
#Override
public void start(Stage primaryStage) {
Login login = new Login();
Scene scene = login.okno();
primaryStage.setTitle("Komunikator sieciowy JAVA");
primaryStage.setScene(scene);
primaryStage.setResizable(false);
primaryStage.show();
}
//public Stage getPrimaryStage() {
// return this.primaryStage;
//}
public static void main(String[] args) {
launch(args);
}
}
Login
public class Login {
private GridPane grid;
private Scene scene;
private Text title;
private Label nick;
private Button wejdzBtn;
private TextField userName;
//private Alert oknoDlg;
public Login() {
grid = new GridPane();
grid.setAlignment (Pos.CENTER);
grid.setHgap(10);
grid.setVgap(10);
grid.setPadding(new Insets(25,25,25,25));
scene = new Scene (grid, 300, 150);
utworzBtn();
utworzLogin();
utworzTekst();
utworzNick();
//oknoDialogowe();
}
//private void oknoDialogowe() {
//Alert oknoDlg = new Alert(Alert.AlertType.CONFIRMATION);
//oknoDlg.setTitle("Informacja");
//oknoDlg.setContentText("test");
// oknoDlg.setHeaderText(null);
//oknoDlg.showAndWait();
//}
private void utworzBtn() {
wejdzBtn = new Button("Zaloguj si\u0119");
HBox hbBtn = new HBox(10);
hbBtn.setAlignment (Pos.BOTTOM_RIGHT);
hbBtn.getChildren().add(wejdzBtn);
grid.add(hbBtn, 1, 2);
//wejdzBtn.setDisable(true);
wejdzBtn.setOnAction(e -> {
Messages mess = new Messages();
grid.getScene().setRoot(mess.messa());;
});
}
private void utworzLogin() {
nick = new Label("Nick:");
grid.add(nick, 0, 1);
}
private void utworzNick() {
userName = new TextField();
grid.add(userName,1,1);
// informacja w polu tekstowym
userName.setPromptText("Max 15 znak\u00f3w");
userName.setFocusTraversable(false);
//maksymalna ilość znaków
final int maxLength = 15;
userName.setOnKeyTyped(t -> {
if (userName.getText().length() > maxLength)
{
int pos = userName.getCaretPosition();
userName.setText(userName.getText(0, maxLength));
userName.positionCaret(pos);
}
});
}
private void utworzTekst() {
title = new Text ("Dzień dobry!");
title.setFont(Font.font("Calibri", FontWeight.NORMAL, 20));
grid.add(title, 0, 0, 2, 1);
}
public Scene okno() {
return scene;
}
}
and and a little another class that I'm trying to change with button from login.java
public class Messages {
private AnchorPane anchor;
private Scene scena;
//private Label nick;
private Button sendBtn;
private TextField poleDoWpisywania;
private TextArea poleDoWyswietlania, pobierzNick;
public Messages() {
anchor = new AnchorPane();
scena = new Scene(anchor, 700, 600);
pobierzNick();
poleDoWpisywania();
poleDoWyswietlania();
utworzPrzycisk();
}
private void utworzPrzycisk() {
sendBtn = new Button("Wy\u015Blij");
sendBtn.setDisable(true);
}
private void pobierzNick(){
pobierzNick = new TextArea();
pobierzNick.setEditable(false);
pobierzNick.setWrapText(true);
}
private void poleDoWpisywania() {
poleDoWpisywania = new TextField();
}
private void poleDoWyswietlania() {
poleDoWyswietlania = new TextArea();
poleDoWyswietlania.setEditable(false);
poleDoWyswietlania.setWrapText(true);
}
public Pane messa() {
return anchor;
}
}
could I ask you to show the right way to fix the bug?

JavaFX defines a scene graph which is a tree data structure that has a single root node. For your application (i.e. the code you posted), the root node is the primaryStage (this is the parameter in method start() in class Main). The primaryStage can have several Scenes. Each Scene must have its own root node.
The error message you are getting means that a Scene's root cannot also be the root of another Scene. In other words anchor is the root for scena in class Messages which means it can't be set as the root for scene in class Login.
Apart from that, if you want to change Scene's you need to call method setScene() of class Stage. Here is your Login class and Messages class with changes that solve the run-time error you are getting and perform the scene change when the user clicks on wejdzBtn button.
Login.java
(I only changed the lambda expression in method utworzBtn().)
public class Login {
private GridPane grid;
private Scene scene;
private Text title;
private Label nick;
private Button wejdzBtn;
private TextField userName;
public Login() {
grid = new GridPane();
grid.setAlignment(Pos.CENTER);
grid.setHgap(10);
grid.setVgap(10);
grid.setPadding(new Insets(25,25,25,25));
scene = new Scene(grid, 300, 150);
utworzBtn();
utworzLogin();
utworzTekst();
utworzNick();
}
private void utworzBtn() {
wejdzBtn = new Button("Zaloguj si\u0119");
HBox hbBtn = new HBox(10);
hbBtn.setAlignment (Pos.BOTTOM_RIGHT);
hbBtn.getChildren().add(wejdzBtn);
grid.add(hbBtn, 1, 2);
wejdzBtn.setOnAction(e -> {
Messages mess = new Messages();
Window w = scene.getWindow();
if (w instanceof Stage) {
Stage s = (Stage) w;
s.setScene(mess.getScena());
}
});
}
private void utworzLogin() {
nick = new Label("Nick:");
grid.add(nick, 0, 1);
}
private void utworzNick() {
userName = new TextField();
grid.add(userName,1,1);
userName.setPromptText("Max 15 znak\u00f3w");
userName.setFocusTraversable(false);
final int maxLength = 15;
userName.setOnKeyTyped(t -> {
if (userName.getText().length() > maxLength)
{
int pos = userName.getCaretPosition();
userName.setText(userName.getText(0, maxLength));
userName.positionCaret(pos);
}
});
}
private void utworzTekst() {
title = new Text ("Dzień dobry!");
title.setFont(Font.font("Calibri", FontWeight.NORMAL, 20));
grid.add(title, 0, 0, 2, 1);
}
public Scene okno() {
return scene;
}
}
Messages.java
(I added method getScena().)
public class Messages {
private AnchorPane anchor;
private Scene scena;
private Button sendBtn;
private TextField poleDoWpisywania;
private TextArea poleDoWyswietlania, pobierzNick;
public Messages() {
anchor = new AnchorPane();
scena = new Scene(anchor, 700, 600);
pobierzNick();
poleDoWpisywania();
poleDoWyswietlania();
utworzPrzycisk();
}
private void utworzPrzycisk() {
sendBtn = new Button("Wy\u015Blij");
sendBtn.setDisable(true);
}
private void pobierzNick() {
pobierzNick = new TextArea();
pobierzNick.setEditable(false);
pobierzNick.setWrapText(true);
}
private void poleDoWpisywania() {
poleDoWpisywania = new TextField();
}
private void poleDoWyswietlania() {
poleDoWyswietlania = new TextArea();
poleDoWyswietlania.setEditable(false);
poleDoWyswietlania.setWrapText(true);
}
public Scene getScena() {
return scena;
}
public Pane messa() {
return anchor;
}
}

Thanks a lot Abra, I've been thinking about it for the last 6 hours and haven't noticed this problem. I have also removed
public Pane messa ();
return anchor;
I do not need it ;)

Event handing issue in Controller in JavaFX and MVC (Not FXML)

I am trying to handle event inside controller. How can i make "Create Profile" button work inside controller. Here are my classes:
main class
public class ApplicationLoader extends Application {
private OptionsModuleChooserRootPane view;
#Override
public void init() {
StudentProfile model = new StudentProfile();
view = new OptionsModuleChooserRootPane();
new OptionsModuleChooserController(view, model);
}
#Override
public void start(Stage stage) throws Exception {
stage.setMinWidth(530);
stage.setMinHeight(550);
stage.setTitle("Final Year Module Chooser Tool");
stage.setScene(new Scene(view));
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Main View
public class OptionsModuleChooserRootPane extends BorderPane {
Menu fileMenu;
Menu helpMenu;
MenuBar menuBar;
TabPane tabPane;
List<Tab> tabs;
public CreateProfileTab profilePane;
public SelectModulesTab modulesPane;
public OverviewSelectionPane overviewPane;
public OptionsModuleChooserRootPane() {
fileMenu = new Menu("File");
helpMenu = new Menu("Help");
menuBar = new MenuBar();
tabPane = new TabPane();
tabs = new ArrayList<>();
//------------------ File menu ----------------------------
fileMenu.getItems().add(new MenuItem("Load Student Data"));
fileMenu.getItems().add(new MenuItem("Save Student Data"));
fileMenu.getItems().add(new MenuItem("Exit"));
//----------------- Help menu -----------------------------
helpMenu.getItems().add(new MenuItem("About"));
//----------------- MenuBar containing all menus ---------
menuBar.getMenus().addAll(fileMenu,helpMenu);
this.setTop(menuBar);
profilePane = new CreateProfileTab();
modulesPane = new SelectModulesTab();
overviewPane = new OverviewSelectionPane();
//-------------------------------- Tabs -----------------------------------------------------
tabs.add(addNewTab(tabPane, "Create Profile", profilePane, false));
tabs.add(addNewTab(tabPane, "Select Modules", modulesPane, false));
tabs.add(addNewTab(tabPane, "Overview Selection", overviewPane, false));
this.setCenter(tabPane);
}
private Tab addNewTab(final TabPane tabPane, String newTabName, Pane newTabContent, boolean isCloseable) {
Tab newTab = new Tab(newTabName);
newTab.setContent(newTabContent);
newTab.setClosable(isCloseable);
tabPane.getTabs().add(newTab);
return newTab;
}
}
I have created separate files for all three tabs. Here is the "Create Profile" tab class which has the button i am trying to handle event of.
public class CreateProfileTab extends GridPane {
private Label lSelectCousrse;
private ComboBox<Course> cboCourses;
private Label lPNumber;
private TextField tfPNumber;
private Label lFirstName;
private TextField tfFirstName;
private Label lSurname;
private TextField tfSurname;
private Label lEmail;
private TextField tfEmail;
private Label lDate;
private DatePicker datePicker;
private HBox hboxDate;
private Button btnCreateProfile;
private StudentProfile student = null;
private Name name;
public CreateProfileTab(){
this.setMinSize(400, 200);
this.setPadding(new Insets(10, 10, 10, 10));
this.setVgap(15);
this.setHgap(20);
this.setAlignment(Pos.CENTER);
lSelectCousrse = new Label("Select course:");
cboCourses = new ComboBox<Course>();
lPNumber = new Label("Input P number:");
tfPNumber = new TextField();
lFirstName = new Label("Input first name:");
tfFirstName = new TextField();
lSurname = new Label("Input surname");
tfSurname = new TextField();
lEmail = new Label("Input email:");
tfEmail = new TextField();
lDate = new Label("Input date:");
datePicker = new DatePicker();
hboxDate = new HBox(datePicker);
btnCreateProfile = new Button("Create Profile");
this.add(lSelectCousrse, 0, 0);
GridPane.setHalignment(lSelectCousrse, HPos.RIGHT);
this.add(cboCourses, 1, 0);
this.add(lPNumber, 0, 1);
GridPane.setHalignment(lPNumber, HPos.RIGHT);
this.add(tfPNumber, 1, 1);
this.add(lFirstName,0,2);
GridPane.setHalignment(lFirstName, HPos.RIGHT);
this.add(tfFirstName,1,2);
this.add(lSurname,0,3);
GridPane.setHalignment(lSurname, HPos.RIGHT);
this.add(tfSurname,1,3);
this.add(lEmail,0,4);
GridPane.setHalignment(lEmail, HPos.RIGHT);
this.add(tfEmail,1,4);
this.add(lDate,0,5);
GridPane.setHalignment(lDate, HPos.RIGHT);
this.add(hboxDate,1,5);
this.add(btnCreateProfile,1,6);
}
public void populateComboBoxWithCourses(Course[] courses) {
cboCourses.getItems().addAll(courses);
cboCourses.getSelectionModel().select(0);
}
public Button getButton(){
return this.btnCreateProfile;
}
}
And here is my controller
public class OptionsModuleChooserController implements EventHandler<ActionEvent> {
private OptionsModuleChooserRootPane view;
private StudentProfile model;
public OptionsModuleChooserController(OptionsModuleChooserRootPane view, StudentProfile model) {
this.model = model;
this.view = view;
this.view.profilePane.populateComboBoxWithCourses(setupAndRetrieveCourses());
}
private Course[] setupAndRetrieveCourses() {
.......
}
#Override
public void handle(ActionEvent event) {
final Object source = event.getSource();
if (source.equals(this.view.profilePane.getButton())) {
System.out.println("Button has been pressed!");
}
}
}

Creating Custom Cell in JavaFX [duplicate]

I am building a JavaFx application and I want to create a method that receives a GridPane and a Node[] with the amount of items being added to the pane. However, when I call the method I get a NoSuchMethodException.
As a test, I tried to create a simple method private String helloWorld() that would return "Hello World";. This method does work, but when I try to run gridLogin = buildForm(gridLogin, items);, I get the Exception in thread "main" java.lang.NoSuchMethodException error.

This will solve your problem, install e(fx)clipse this plugin for eclise but i dont know for intellij ,or add facet for your application as javafx application, if you add facet you dont need main method , or use like this
public class DesktopApplication extends Application {
#Override
public void start(Stage primaryStage) {
BuildGraphicalUserInterface ui = new BuildGraphicalUserInterface();
ui.initStage(primaryStage);
}
public static void main(String[] args) {
launch(args);
}
}

How do you call graphics class from main class in JavaFX?

I'm a really new programmer so idk if this question sounds really stupid but..
This is my main:
package culminating;
import javafx.application.Application;
& all other necessary imports...
public class CulminatingMAIN extends Application {

int count = 0;
String name;
String gender = "Boy";

Now I have another class called CharacterGraphic, which I want to call and make the graphic I created in it appear.
package culminating;
& all the other imports
public class CharacterGraphic extends Culminating_JavaFX {
public void start(Stage primaryStage) throws Exception {
String gender = "boy";
Pane pane = new Pane();
pane.setStyle("-fx-background-color: LIGHTBLUE");
pane.setPrefSize(200, 200);
Circle head = new Circle();
head.setRadius(50);
head.setCenterX(240);
head.setCenterY(120);
head.setFill(Color.BURLYWOOD);
etc etc (all other graphics i made)
How do I do this???? And where would I do this?? Any answers really, really appreciated!

output:
I have made a rough example without using proper layouts. You use the appropriate layout for your UI. Populate the combobox with your data5 list and in the action listener of the combo box check for the selected value and fill other fields.
Update
Since you have to use only text box as your company said, the below links guide you in that. You have to create a customized text box by extending the Text class of Javafx.
