Question

我有一个应用程序，我想在打开一个新的JavaFX框后初始化一些东西。我意识到这被标记为重复，但我不知道这个重复的答案如何帮助我。答案让我困惑，我只是想在新打开的窗口上初始化一些东西

以下是此新窗口的代码：

从第一个窗口打开另一个窗口的方法：

@FXML
    public void displayAddNewPerson() {

        FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("CreateNewStudent.fxml"));
        Parent root;
        AddNewPersonToFile activateMethod = new AddNewPersonToFile();
        try {
            root = fxmlLoader.load();
            Stage addNewPersonStage = new Stage();
            addNewPersonStage.initModality(Modality.APPLICATION_MODAL);
            addNewPersonStage.setOpacity(1);
            addNewPersonStage.setTitle("My New Stage Title");
            addNewPersonStage.setScene(new Scene(root, 500, 300));
            addNewPersonStage.show();
            addNewPersonStage.hide();
            //activateMethod.initializeNewPerson();
            addNewPersonStage.showAndWait();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


    }

是新窗口的类：

public class AddNewPersonToFile extends AnchorPane implements Initializable {
    @FXML
    final ObservableList<String> stateList =FXCollections.observableArrayList(
            "AL", "AK", "AZ", "AR", "CA", "CO", "CT", "DE", "FL", "GA", "HI", "ID", "IL", "IN", 
            "IA","KS", "KY", "LA", "ME", "MD", "MA", "MI", "MN", "MS", "MO", "MT", "NE", "NV", 
            "NH", "NJ", "NM", "NY", "NC", "ND", "OH", "OK", "OR", "PA", "RI", "SC", "SD", "TN", 
            "TX","UT", "VT", "VA", "WA", "WV", "WI", "WY");
@FXML
private TextField enterLastName;
@FXML
private TextField enterFirstName;
@FXML
private TextField enterEmail;
@FXML
private TextField enterMoneyOwed;
@FXML
private TextField enterSchoolName;
@FXML
private ComboBox<String> enterState; 
@FXML
private ComboBox<Integer> enterYearJoined;
@FXML
private CheckBox enterIsHeActive;
@FXML
private Button enterStudentInfo;

@Override
public void initialize(URL location, ResourceBundle resources) {
    // TODO Auto-generated method stub



    int year = Calendar.getInstance().get(Calendar.YEAR);
    ObservableList<Integer> yearRange = FXCollections.observableArrayList((year - 4), (year - 3), (year - 2), (year - 1), (year), (year + 1), (year + 2), (year + 3), (year + 4));
    enterIsHeActive.setIndeterminate(false);
    System.setProperty("glass.accessible.force", "false");
    enterState.setVisibleRowCount(4);
    enterState.setItems(stateList);
    enterYearJoined.setItems(yearRange);
    enterYearJoined.setVisibleRowCount(4);


}

}

这是新窗口的FXML：

Answer 1

Stage newStage;//declare a new stage out of the action event

@FXML
private void andNewBtnAction(ActionEvent event) throws IOException {
    newStage = new Stage();
    newStage.setTitle("Add New");
    //container of your parent FXML (you can set blur effect to your parent once your new window open )
    stackPane.setEffect(new GaussianBlur(10));

    newStage.setScene(new Scene(FXMLLoader.
            load(URL_TO_YOUR_FXML));
    newStage.setResizable(false);
    newStage.initModality(Modality.WINDOW_MODAL);
    newStage.initOwner(YOUR_PRIMARY_STAGE);
    newStage.show();
    newStage.setOnCloseRequest((WindowEvent t) -> {
        stackPane.setEffect(null);//remove the effect after you close the new window
        newStage = null;
    });
}

通过单击新按钮在JavaFX中打开一个新窗口后，我想初始化一些东西。怎么样？
