使用SceneBuilder 2.0创建的Java 8的FXML与NetBeans Gluon（插件）项目相结合？

标签： android javafx fxml netbeans-8 javafxports

我能够创建和运行JavaFX FXML＆＃34; hello world＆＃34;使用NetBeans的程序。我安装了Gluon插件，允许JavaFX程序使用相同的代码库部署到桌面，IOS和Android。我试图将两者结合起来（FXML）......以获得一个'＃hello world＆＃34;程序，其中GUI部分是使用SceneBuilder 2.0在FXML中创建的，并部署到桌面，Android和＆amp; IOS通过使用Gluon插件创建的项目构建的项目。

这里是主要方法的代码...... 

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);
    }

}

这是来自控制器的代码...... 

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
    }    

}

这是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>

我收到的错误是......

该错误意味着它无法找到FXML文件。

在Projects视图的Resources [Main]包下，您应该创建包FXMLDocument.fxml并放置src |-- main | |-- java | | |-- com | | | |-- troyfirstgluonfxapplication | | | | |-- TroyFirstGluonFXApplication.java | | | | |-- FXMLDocumentController.java | |-- resources | | |-- com | | | |-- troyfirstgluonfxapplication | | | | |-- FXMLDocument.fxml 文件。

如果选中“文件”视图，则应该具有以下内容：

@Override
public void start(Stage stage) throws Exception {
    Parent root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml"));

    Rectangle2D visualBounds = Screen.getPrimary().getVisualBounds();
    Scene scene = new Scene(root, visualBounds.getWidth(), visualBounds.getHeight());

    stage.setScene(scene);
    stage.show();
}

另请注意，您可以将fxml加载与插件为您生成的代码组合在一起：
