在stageAdd窗口更新工作人员并按下按钮ok时，refreshButtonClicked()上的stage.setOnCloseRequest((e)-> refreshButtonClicked());方法未执行。更新完成并单击按钮确定后，应自动刷新workersTable。
我在stageAdd方法中按下编辑按钮时使用editButtonClicked()。
public class ElectricalDepartmentController {

private final ObservableList<Worker> workersList = FXCollections.observableArrayList();
//initialize method
public void initialize() throws IOException {
workersTableColumn.setCellValueFactory(new PropertyValueFactory<>("nameSurname"));
rowSelected();
}
//Refresh the table when the button is clicked
@FXML
public void refreshButtonClicked() {
workersList.removeAll(workersList);
populateTable();
}
//Delete worker
@FXML
private void deleteButtonClicked() {
Worker selectedWorker = workersTable.getSelectionModel().getSelectedItem();
workersTable.getItems().remove(selectedWorker);
workerDao.deleteSelectedWorker(selectedWorker, "Electrical");
}
//Populate the table
@FXML
public void populateTable() {
for(Worker worker : workerDao.getWorkersNameSurname("Electrical")) workersList.addAll(worker);
workersTable.setItems(workersList);
}
//Show worker's information when row is selected
@FXML
private void rowSelected() {
workersTable.getSelectionModel().selectedItemProperty().
addListener((observable, oldValue, newValue) -> {
if (newValue != null) {
name.setText(workerDao.getWorkersInfoByNameSurname(newValue.getNameSurname()).getName());
surname.setText(workerDao.getWorkersInfoByNameSurname(newValue.getNameSurname()).getSurname());
age.setText(String.valueOf(workerDao.getWorkersInfoByNameSurname(newValue.getNameSurname()).getAge()));
city.setText(workerDao.getWorkersInfoByNameSurname(newValue.getNameSurname()).getContactInformation().getCity());
address.setText(workerDao.getWorkersInfoByNameSurname(newValue.getNameSurname()).getContactInformation().getAddress());
telephoneNum.setText(workerDao.getWorkersInfoByNameSurname(newValue.getNameSurname()).getContactInformation().getTelephoneNum());
email.setText(workerDao.getWorkersInfoByNameSurname(newValue.getNameSurname()).getContactInformation().getEmail());

netSalary.setText(String.valueOf(workerDao.getWorkersInfoByNameSurname(newValue.getNameSurname()).getEmploymentInformation().getNetSalary()));
}
});
}
@FXML
public void editButtonClicked() throws IOException {
Worker workerSelectedForEdit = workersTable.getSelectionModel().getSelectedItem();
FXMLLoader loader = new FXMLLoader(getClass().getResource("/views/StageAdd.fxml"));
Parent parent = loader.load();
StageAddController controller = loader.getController();
controller.showEditWorkerOldInformation(workerSelectedForEdit);
Stage stage = new Stage();
stage.setTitle("Edit Worker");
stage.setScene(new Scene(parent));
parent.getStylesheets().add("/css/redBorder.css");
stage.show();
stage.setOnCloseRequest((e)-> refreshButtonClicked());
}
}
关闭stageAdd并在stageAdd控制器类中保存/更新工作程序的方法：
//Close Stage
@FXML private void closeButtonClicked(){
Stage stage = (Stage) rootPane.getScene().getWindow();
stage.close();
}
//Submit entered information - OK button pressed
@FXML private void okButtonClicked() throws IOException{
WorkerDao workerDao = WorkerDaoFactory.getWorkerDao();
List<Control> requiredFieleds = new ArrayList<>();
int count=0;
// Getting required fields
for(Control c : allControls){
if(!c.equals(email) && !c.equals(endDate)){
requiredFieleds.add(c);
}
}
//Check if all required fields are valid
for (Control c : requiredFieleds) {
if (c instanceof TextField) {
if (!stageAddService.validateField((TextField)c, field-> field.getText().trim().isEmpty()))
count++;
else c.pseudoClassStateChanged(errorClass, true);
}
else if (c instanceof DatePicker){
if (!stageAddService.validateField((DatePicker)c, field-> field.getValue()==null))
count++;
else c.pseudoClassStateChanged(errorClass1, true);
}
else {
if (!stageAddService.validateField((ChoiceBox)c, field-> field.getValue()==null))
count++;
else c.pseudoClassStateChanged(errorClass2, true);
}
}
//If required fields are valid, save data
if (count == requiredFieleds.size()) {
Worker worker = new Worker();
worker.setName(name.getText().trim());
worker.setSurname(surname.getText().trim());
worker.setAge(age.getValue());
ContactInformation contactInformation = new ContactInformation();
contactInformation.setAddress(address.getText().trim());
contactInformation.setCity(city.getText().trim());
contactInformation.setTelephoneNum(telephoneNumber.getText().trim());
contactInformation.setEmail(email.getText().trim());
worker.setContactInformation(contactInformation);
EmploymentInformation employmentInformation = new EmploymentInformation();
employmentInformation.setDepartment(departmentBox.getValue());
employmentInformation.setIdNumber(Long.parseLong(idNumber.getText().trim()));
employmentInformation.setStartDate(startDate.getValue());
employmentInformation.setContractType(contractType.getValue());
employmentInformation.setEndDate(endDate.getValue());
employmentInformation.setPayFreq(payFrequency.getValue());
employmentInformation.setAccountNum(Long.parseLong(accountNumber.getText().trim()));
employmentInformation.setTaxCoeficient(Double.parseDouble(taxCoeficient.getText().trim()));
employmentInformation.setNetSalary(Double.parseDouble(netSalary.getText().trim()));
worker.setEmploymentInformation(employmentInformation);
if(isInEditMode){
worker.setId(id);
workerDao.updateWorker(worker);
}
else {workerDao.saveWorker(worker);}
closeButtonClicked();
}
else {error1.setText("Fill in all red fields");
error2.setText("Fill in all red fields");
}
}
其他类中加载stageAdd
public static void showStageAdd() throws IOException {
FXMLLoader loader = new FXMLLoader();
loader.setLocation(Main.class.getResource("/views/StageAdd.fxml"));
BorderPane addWorkerPane = loader.load();
stageAdd = new Stage();
stageAdd.setTitle("Add New Worker");
stageAdd.resizableProperty().setValue(Boolean.FALSE);
Scene scene = new Scene(addWorkerPane);
scene.getStylesheets().add("/css/redBorder.css");
stageAdd.setScene(scene);
stageAdd.initModality(Modality.WINDOW_MODAL);
stageAdd.initOwner(stage1);
stageAdd.showAndWait();
}
答案 0 :(得分：2)
我们遇到了类似的问题 - ＆gt;以下代码：
stage.setOnCloseRequest((e)-> refreshButtonClicked());
当窗口通过窗口上的“X”关闭时，将调用此方法。但是这段代码
Stage stage = (Stage) rootPane.getScene().getWindow();
stage.close();
实际上不会调用关闭请求。您可以通过向窗口发送close事件而不是stage.close（）来完成此操作，或者您可以执行此操作：
stage.setOnHidden((e)-> refreshButtonClicked());
