FXML 文件中的 getHostServices().showDocument() [英] getHostServices().showDocument() in a FXML File

问题描述

有没有什么简单的方法可以以某种方式将 getHostServices().showDocument() 命令放入 toHomepage() 方法中，而不是执行几行和几行代码，因此代码应该看起来干净简单?

包示例；导入 javafx.application.HostServices;导入 javafx.event.ActionEvent;导入 javafx.fxml.FXML;导入 javafx.scene.control.Button;公共类控制器{@FXML私人按钮 facebookButton;@FXMLvoid toHomepage(ActionEvent 事件) {}}

如果我按下按钮，它应该直接将我链接到 Facebook 网址

解决方案

您需要将 HostServices 传递给 Controller.

<块引用>

Key Code:在Controller中设置HostServices.

HostServices 主机服务；public void setGetHostController(HostServices hostServices){this.hostServices = 主机服务；}

<块引用>

关键代码:将HostServices传递给Controller.

FXMLLoader loader = new FXMLLoader(getClass().getResource("FXMLDocument.fxml"));父根 = loader.load();FXMLDocumentController fXMLDocumentController = loader.getController();fXMLDocumentController.setGetHostController(getHostServices());

FXML

<儿童><Button layoutX="126" layoutY="90" text="点击我！"onAction="#handleButtonAction" fx:id="button"/><Label layoutX="126" layoutY="120" minHeight="16" minWidth="69" fx:id="label"/></儿童></AnchorPane>

Is there any easy way to put into the toHomepage() method the getHostServices().showDocument() command somehow, instead of doing lines and lines of code, so the code should look clean and simple?

package sample;

import javafx.application.HostServices;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.scene.control.Button;

public class Controller {

   @FXML
   private Button facebookButton;

   @FXML
   void toHomepage(ActionEvent event) {

   }


}

If I press the button, it should directly link me to the Facebook URL

解决方案

You need to pass the HostServices to the Controller.

Key Code: Set the HostServices in the Controller.

HostServices hostServices ;

public void setGetHostController(HostServices hostServices)
{
    this.hostServices = hostServices;
}        

Key Code: Passing HostServices to the Controller.

FXMLLoader loader = new FXMLLoader(getClass().getResource("FXMLDocument.fxml"));
Parent root = loader.load();
FXMLDocumentController fXMLDocumentController = loader.getController();
fXMLDocumentController.setGetHostController(getHostServices());

Main

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

/**
 *
 * @author sedrick
 */
public class JavaFXApplication7 extends Application {

    @Override
    public void start(Stage stage) throws Exception {
        FXMLLoader loader = new FXMLLoader(getClass().getResource("FXMLDocument.fxml"));
        Parent root = loader.load();
        FXMLDocumentController fXMLDocumentController = loader.getController();
        fXMLDocumentController.setGetHostController(getHostServices());

        Scene scene = new Scene(root);        
        stage.setScene(scene);
        stage.show();
    }

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        launch(args);
    }

}

Controller

import java.net.URL;
import java.util.ResourceBundle;
import javafx.application.HostServices;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Label;

/**
 *
 * @author sedri
 */
public class FXMLDocumentController implements Initializable {

    HostServices hostServices;

    @FXML
    private Label label;

    @FXML
    private void handleButtonAction(ActionEvent event) {
        hostServices.showDocument("www.google.com");
    }

    @Override
    public void initialize(URL url, ResourceBundle rb) {
        // TODO
    }    

    public void setGetHostController(HostServices hostServices)
    {
        this.hostServices = hostServices;
    }

}
