とコードは、このFXMLをbehoynd -

import java.net.URL; 
import java.util.HashMap; 
import java.util.Map; 
import java.util.ResourceBundle; 

import com.jfoenix.controls.JFXButton; 
import com.jfoenix.controls.JFXTextArea; 

import emuns.ImageStatus; 
import javafx.fxml.FXML; 
import javafx.fxml.Initializable; 
import javafx.scene.image.ImageView; 
import javafx.scene.input.MouseEvent; 
import utils.Constants; 

public class ScannerController implements Initializable { 

@FXML 
private ImageView imgDownload; 

@FXML 
private ImageView imgProccessing; 

@FXML 
private ImageView imgClassify; 

@FXML 
private ImageView imgDifference; 

@FXML 
private ImageView imgFinal; 

@FXML 
private JFXTextArea txtProgress; 

@FXML 
private JFXButton btnStartScanning; 

@FXML 
private JFXButton btnStopScanning; 

Map<String, ImageView> mapping = new HashMap<>(); 

@FXML private FXMLDrawerController drawerController; 


public ScannerController() { 
} 

@Override 
public void initialize(URL location, ResourceBundle resources) { 
    mapping.put("Downloading", imgDownload); 
    mapping.put("Processing", imgProccessing); 
    mapping.put("Classify", imgClassify); 
    mapping.put("Differance", imgDifference); 
    mapping.put("Final", imgFinal); 
} 

public void setDrawerController(FXMLDrawerController drawerController) { 
    this.drawerController = drawerController; 
} 


@FXML 
void handleStartButton(MouseEvent event) { 
    drawerController.startScanning(); 
} 

@FXML 
void handleStopButton(MouseEvent event) { 
    drawerController.startScanning(); 
} 
} 

誰かが問題を見て、私を助けることができますか？ 私の問題を解決する方法がわかりません。私はいつも私のアドバイスを与えることができますか？ TNX

Answer 1

利用ActionEvent代わりのMouseEvent

@FXML 
void handleStartButton(ActionEvent event) { 
    drawerController.startScanning(); 
} 

@FXML 
void handleStopButton(ActionEvent event) { 
    drawerController.startScanning(); 
}
