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

问题描述

有没有简单的方法将getHostServices（）。showDocument（）命令以某种方式放入toHomepage（）方法，而不是执行代码行和代码行，所以代码应该看起来干净简单？

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) {

   }


}

如果我按下按钮，它应该直接将我链接到Facebook网址

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

推荐答案

您需要将 HostServices 传递给控制器。

密钥代码：在控制器中设置 HostServices 。

HostServices hostServices ;

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

密码：传递 HostServices 到控制器。

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

Main

Main

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

/**

 */
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);
    }

}

控制器

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;
    }

}
