JavaFX popup not working - javafx

Question

I’m trying to learn how to get a JavaFX popup window to open from a menu item click. I finally got a new window to open but I can’t seem to make it modal. Here's my code:
Scene 1 FXML:
<AnchorPane id="AnchorPane" prefHeight="200" prefWidth="320" xmlns="http://javafx.com/javafx/8.0.111" xmlns:fx="http://javafx.com/fxml/1" fx:controller="sceneswitchtest.Scene_1Controller">
<children>
<Button fx:id="button" layoutX="126" layoutY="90" onAction="#handleButtonAction" text="Click Me!" />
<Label fx:id="label" layoutX="126" layoutY="120" minHeight="16" minWidth="69" />
<MenuBar fx:id="menuBar" layoutX="40.0" layoutY="27.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0">
<menus>
<Menu mnemonicParsing="false" text="File">
<items>
<MenuItem mnemonicParsing="false" text="Close" />
<MenuItem fx:id="MenuItemOpenScene2" mnemonicParsing="false" onAction="#OpenScene2" text="Open Scene 2" />
</items>
</Menu>
<Menu mnemonicParsing="false" text="Edit">
<items>
<MenuItem mnemonicParsing="false" text="Delete" />
</items>
</Menu>
<Menu mnemonicParsing="false" text="Help">
<items>
<MenuItem mnemonicParsing="false" text="About" />
</items>
</Menu>
</menus>
</MenuBar>
</children>
</AnchorPane>
Popup FXML:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.layout.AnchorPane?>
<AnchorPane id="AnchorPane" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/8.0.111" xmlns:fx="http://javafx.com/fxml/1" fx:controller="sceneswitchtest.Scene_2Controller">
</AnchorPane>
Scene 1 controller:
package sceneswitchtest;
import java.io.IOException;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.scene.Node;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.MenuBar;
import javafx.scene.control.MenuItem;
import javafx.stage.Modality;
import javafx.stage.Stage;
public class Scene_1Controller {
#FXML
private Button button;
#FXML
private Label label;
#FXML
private MenuBar menuBar;
#FXML
private MenuItem MenuItemOpenScene2;
#FXML
void OpenScene2(ActionEvent event) throws IOException {
Stage appStage = (Stage) ((Node) menuBar).getScene().getWindow();
Parent settingsParent = FXMLLoader.load(this.getClass().getResource("Scene_2.fxml"));
Scene settingsScene = new Scene(settingsParent);
appStage.setScene(settingsScene);
// appStage.initModality(Modality.WINDOW_MODAL);
// appStage.initOwner(menuBar.getScene().getWindow());
appStage.show();
}
#FXML
void handleButtonAction(ActionEvent event) throws IOException {
}
}
Note: In the above code, the lines commented out failed as well as he use of Modality.APPLICATION_MODAL
Scene 2 (popup) controller:
package sceneswitchtest;
public class Scene_2Controller {
}
main method:
package sceneswitchtest;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
/**
*
* #author eric
*/
public class SceneSwitchTest extends Application {
#Override
public void start(Stage stage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("Scene_1.fxml"));
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
}

Here is the code changes I made in order to get the popup to work.
#FXML
void OpenScene2(ActionEvent event) throws IOException {
Parent settingsParent = FXMLLoader.load(this.getClass().getResource("/sceneswitchtest/Scene_2.fxml"));
Scene settingsScene = new Scene(settingsParent);
Stage popup = new Stage();
popup.setScene(settingsScene);
popup.initModality(Modality.WINDOW_MODAL);
popup.initOwner(menuBar.getScene().getWindow());
popup.show();
}
I would like to thank MBec for pointing me in the right direction.
