有什么简单的方法可以将getHostServices()。showDocument()命令以某种方式放入toHomepage()方法中,而不是执行几行代码,因此代码应该看起来简洁明了?
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 URL
最佳答案
您需要将HostServices
传递给Controller
。
密钥代码:在HostServices
中设置Controller
。
HostServices hostServices ;
public void setGetHostController(HostServices hostServices)
{
this.hostServices = hostServices;
}
密钥代码:将
HostServices
传递给Controller
。FXMLLoader loader = new FXMLLoader(getClass().getResource("FXMLDocument.fxml"));
Parent root = loader.load();
FXMLDocumentController fXMLDocumentController = loader.getController();
fXMLDocumentController.setGetHostController(getHostServices());
主要
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);
}
}
