Я могу создать и запустить программу "hello world" JavaFX FXML, используя NetBeans. Я установил подключаемый модуль Gluon, который позволит развертывать программы JavaFX на рабочем столе, IOS и Android с использованием одной и той же кодовой базы. Я пытаюсь объединить два (FXML)... чтобы получить программу «hello world», в которой часть GUI была создана в FXML с использованием SceneBuilder 2.0 и развернута на рабочем столе, Android и IOS через проекты построен с проектом, созданным плагином Gluon.
Вот код из основного метода...
package com.troyfirstgluonfxapplication;
import javafx.application.Application;
import static javafx.application.Application.launch;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
/**
*
* @author tfrericks
*/
public class TroyFirstGluonFXApplication 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();
}
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
}
Вот код от контроллера...
package com.troyfirstgluonfxapplication;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Label;
/**
*
* @author tfrericks
*/
public class FXMLDocumentController implements Initializable {
@FXML
private Label label;
@FXML
private void handleButtonAction(ActionEvent event) {
System.out.println("You clicked me!");
label.setText("Hello World!");
}
@Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
}
}
А вот и FXML...
<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.scene.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<AnchorPane id="AnchorPane" prefHeight="200" prefWidth="320" xmlns:fx="http://javafx.com/fxml/1" fx:controller="com.troyfirstgluonfxapplication.FXMLDocumentController">
<children>
<Button layoutX="126" layoutY="90" text="Click Me!" onAction="#handleButtonAction" fx:id="button" />
<Label layoutX="126" layoutY="120" minHeight="16" minWidth="69" fx:id="label" />
</children>
</AnchorPane>
