好的，所以我正在构建这个小小的JavaFX应用程序以及其中的一个
让我感到困惑的是，虽然我的一些阶段会有那样的＆＃34;放大 - 然后淡出＆＃34;动画触发close()。
特别关闭是此代码块中的最后一行代码：
@FXML
public void logout() throws SQLException {
Stage stage = ((Stage) logout_button.getScene().getWindow());
stage.close();
Main.loginStage.show();
}
Main.loginStage.close();
这是方法的课程
public class ListController {
@FXML private ImageView profImg;
@FXML private Button logout_button;
@FXML private TableView<Child> table;
@FXML private TableColumn col_name;
@FXML private TableColumn col_picture;
//TO BE MOVED TO EXTERNAL CLASS
private static Database db;
@FXML
public void initialize() {
db = new Database();
try {
initTable();
} catch (SQLException e){
System.out.println("loading failed");
}
initAvatar();
disableReorder();
}
private void initAvatar() {
profImg.setClip(ImageUtils.getAvatarCircle());
Image value = new Image("file:///" + GlobalInfo.getCurrProfImg().getAbsolutePath());
profImg.setImage(value);
}
public void initTable() throws SQLException {
db.init();
table.setRowFactory(new Callback<TableView<Child>, TableRow<Child>>() {
@Override
public TableRow<Child> call(TableView<Child> param) {
TableRow<Child> row = new TableRow<>();
row.setOnMouseClicked(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent event) {
System.out.println(row.getItem().getId());
}
});
return row;
}});
table.setItems(db.getChildren());
col_picture.setCellValueFactory(new PropertyValueFactory<Child, File>("image"));
col_picture.setCellFactory(new Callback<TableColumn<Child, File>, TableCell<Child, File>>() {
@Override
public TableCell call(TableColumn param) {
return new TableCell<Child, File>() {
ImageView imageView = new ImageView();
Image childImage;
@Override
protected void updateItem(File item, boolean empty) {
if (item != null) {
childImage = new Image("file:///" + item.getAbsolutePath());
imageView.setImage(childImage);
imageView.setClip(ImageUtils.getAvatarCircle());
imageView.setFitHeight(65);
imageView.setFitWidth(65);
HBox hBox = new HBox(imageView);
hBox.setAlignment(Pos.CENTER);
setGraphic(hBox);
}
}
};
}
});
col_name.setCellValueFactory(new Callback<TableColumn.CellDataFeatures<Child, String>, ObservableValue>() {
@Override
public ObservableValue call(TableColumn.CellDataFeatures<Child, String> param) {
Child child = param.getValue();
String firstName = child.getfName();
String lastName = child.getlName();
String nickname = child.getNickname();
String placeholder = "PLACEHOLDER"; //Place holder for adding nickname if exists
String complete = firstName + placeholder + lastName;
//place nickname between first and last name if exists
if (nickname.length() != 0){
String nicknameString = " \"" + nickname + "\" ";
complete = complete.replace(placeholder, nicknameString);
//if nickname does not exist
} else {
complete = complete.replace(placeholder, "");
}
return new SimpleStringProperty(complete);
}
});
col_name.setCellFactory(new Callback<TableColumn<Child, String>, TableCell<Child, String>>() {
@Override
public TableCell call(TableColumn<Child, String> param) {
return new TableCell<Child, String>() {
@Override
protected void updateItem(String item, boolean empty) {
setText(item);
setAlignment(Pos.CENTER);
}
};
}
});
}
private void disableReorder() {
table.widthProperty().addListener((observable, oldValue, newValue) -> {
TableHeaderRow row = ((TableHeaderRow) table.lookup("TableHeaderRow"));
row.reorderingProperty().addListener((observable1, oldValue1, newValue1) -> row.setReordering(false));
}); //Fuck you oracle
}
@FXML
public void logout() throws SQLException {
Stage stage = ((Stage) logout_button.getScene().getWindow());
stage.close();
Main.loginStage.show();
}
@FXML
public void showSettings() throws IOException {
Parent root = FXMLLoader.load(getClass().getResource("/fxml/settings.fxml"));
SettingsStage stage = new SettingsStage();
stage.setOnHidden((event) -> {
SettingsStage settingsStage = ((SettingsStage) event.getSource());
if (settingsStage.getChange()) {
initialize();
}
});
Scene scene = new Scene(root, 600, 400);
stage.setScene(scene);
stage.setTitle("Settings");
stage.initModality(Modality.APPLICATION_MODAL);
stage.showAndWait();
}
@FXML
public void showChildForm(ActionEvent actionEvent) throws IOException {
FXMLLoader loader = new FXMLLoader(getClass().getResource("/fxml/childForm.fxml"));
Parent root = loader.load();
ChildFormController controller = loader.getController();
controller.setListController(this);
Scene scene = new Scene(root, 575, 675);
scene.getStylesheets().add(getClass().getResource("/css/persistent-prompt.css").toExternalForm());
Stage stage = new Stage();
stage.setResizable(false);
stage.setScene(scene);
stage.setTitle("Add child");
stage.initModality(Modality.APPLICATION_MODAL);
stage.showAndWait();
}
}
然而，我有一些表格阶段没有显示这个＆＃34;动画＆＃34;在调用close()时，他们只是从窗口消失，我发现它很震撼。
这是运行以关闭其中一个故障阶段的代码，其各自的类进一步在下面：

有没有人知道造成这个问题的原因是什么？任何关于SO的搜索都会产生关于淡入淡出阶段的问题，这不是我想要的。
