Question

我有一个混合代码，我正在使用带有Splash Screen的Scene Builder构建程序。我在Anchor Pane顶部的TitledPane上构建了一个按钮，它是root。我设置了fx：id，当我运行时，我无法点击任何内容。甚至不是标题窗格或任何按钮的标签。有趣的是，我可以使用tab键遍历并单击空格以实际鼠标单击它。发生了什么事，我应该怎么做才能解决这个问题？

@FXML
private Label label;

@FXML
private AnchorPane root;

@FXML
private TitledPane tPane;

@FXML
private AnchorPane aPane1;

@FXML
private ListView listView;

@FXML
private Button addBtn;

@FXML
private void addButtonAction(ActionEvent event) {
            FileChooser fc = new FileChooser();
            File selectedFile = fc.showOpenDialog(null);
            if (selectedFile != null){
                listView.getItems().add(selectedFile.getName());  
            }
            else{
                System.out.println("The file is not valid.");
            }
}

@Override
public void initialize(URL url, ResourceBundle rb) {
    // TODO
    if (!MajorProject.isSplashLoaded){
    loadSplashScreen();

    }
}    
private void loadSplashScreen(){
    try {
        AnchorPane aPane = FXMLLoader.load(getClass().getResource("SplashFXML.fxml"));
        root.getChildren().addAll(aPane);
        FadeTransition fadeIn = new FadeTransition(Duration.seconds(3), aPane);
        fadeIn.setFromValue(0);
        fadeIn.setToValue(1);
        fadeIn.setCycleCount(1);

        FadeTransition fadeOut = new FadeTransition(Duration.seconds(3), aPane);
        fadeOut.setFromValue(1);
        fadeOut.setToValue(0);
        fadeOut.setCycleCount(1);

        fadeIn.play();

        fadeIn.setOnFinished((e) -> {
        fadeOut.play();
        MajorProject.isSplashLoaded = true;
        });

        fadeOut.setOnFinished((e) -> {
            try { 
                Parent root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml"));


            } catch (IOException ex) {
                Logger.getLogger(FXMLDocumentController.class.getName()).log(Level.SEVERE, null, ex);
            }

        });

    } catch (IOException ex) {
        Logger.getLogger(FXMLDocumentController.class.getName()).log(Level.SEVERE, null, ex);
    }
}

Answer 1

这是因为您在mouseTransparent="true"设置了属性TitledPane。

在JavaFX中，MouseTransparent属性使任何Node 及其所有孩子忽略任何鼠标交互，这就是您无法单击按钮的原因。只需删除它就可以了。

Node - MouseTransparentProperty

Javafx和fxml按钮无法点击
