我使用javafx创建我的桌面应用程序。当Itried运行我的代码，我不断收到此错误 -线程“JavaFX Application Thread”中的异常java.lang.IllegalArgumentException

和behoynd这FXML代码 -

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(); 
} 
}

是否有人看到了问题，并能帮助我吗？我不知道如何解决我的问题。是somwone可以给我的建议？ TNX

使用ActionEvent，而不是MouseEvent

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

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

它没有工作..。我得到运行时异常 - 了java.lang.RuntimeException：java.lang.reflect.InvocationTargetException –

@DanaS更新您的问题包括新的堆栈跟踪。据推测你使用的是JavaFX的'ActionEvent'，而不是AWT的... –

Tnx @James_D它的工作原理！我没有看到eclipse导入AWT的ActionEvent ... TNX！ –
