Я работаю над проектом Java FX
Я создал два файла FXML, и я хочу загрузить другую панель для основной боли, которая является Border Pane. Я хочу загрузить другую панель в центральную область Border Pane!
Вот моя точка входа в мой проект, который является файлом Java
package javafxapplication8;
import java.io.IOException;
import javafx.application.Application;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
/**
*
* @author Anu
*/
public class JavaFXApplication8 extends Application {
@Override
public void start(Stage stage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml"));
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
@FXML
void handleButtonAction(MouseEvent event) throws IOException {
}
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
}
После этого отображается основной файл FXML, в котором отображается моя граница
<?xml version="1.0" encoding="UTF-8"?>
<?import com.jfoenix.controls.JFXButton?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.layout.BorderPane?>
<AnchorPane id="AnchorPane" prefHeight="200" prefWidth="320" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8.0.171"
fx:controller="javafxapplication8.FXMLDocumentController">
<children>
<BorderPane fx:id="rootStage" layoutX="14.0" layoutY="-14.0" prefHeight="200.0" prefWidth="320.0" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0">
<left>
<JFXButton buttonType="RAISED"
onAction="#handleButtonAction"
text="Load Pane" BorderPane.alignment="CENTER" />
</left>
</BorderPane>
</children>
</AnchorPane>
Я установил кнопку для отображения конкретной панели в центральной области этой границы.
<left>
<JFXButton buttonType="RAISED"
onAction="#handleButtonAction"
text="Load Pane" BorderPane.alignment="CENTER" />
</left>
Это мой класс Controller этой граничной панели, содержащей класс
package javafxapplication8;
import java.io.IOException;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.fxml.Initializable;
import javafx.scene.control.Label;
import javafx.scene.layout.BorderPane;
/**
*
* @author Anu
*/
public class FXMLDocumentController implements Initializable {
@FXML
private BorderPane rootStage;
@FXML
private void handleButtonAction(ActionEvent event) throws IOException {
System.out.println("Button Click");
FXMLLoader loader = new FXMLLoader();
loader.setLocation(javafx.stage.Stage.class.getResource("FXML.fxml"));
BorderPane newScene = loader.load();
rootStage.setCenter(newScene);
}
@Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
System.out.println("FXMLDocumentController");
}
}
И это файл FXML, который я хочу отобразить в центральной области пограничной панели.
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.text.Font?>
<AnchorPane id="AnchorPane" prefHeight="400.0" prefWidth="600.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8.0.171" fx:controller="javafxapplication8.FXMLController">
<children>
<Label layoutX="252.0" layoutY="179.0" text="Label">
<font>
<Font size="41.0" />
</font>
</Label>
</children>
</AnchorPane>
Но когда я нажимаю кнопку, которая дает мне кучу ошибок!

Кто-нибудь может показать мне, где я скучаю? Спасибо.
