How to refresh database tableview after updating or Deleting In Javafx?

I have two Controller class(Controller and Dailog Controller). COntroller class has tableView. On Double click on Tableview row the Dialog popup. The dialogController class has two button i.e update and delete.
The Update button updating and deleting data in database. After updating or deleting i want to refresh tableview. The problem is tablview refresh method is in Controller class. So how can i refresh it?

Snapcshot of Application

You can add this to the DialogBoxController class:
public class DialogBoxController {
private Controller controller;
public void setController(Controller controller){
this.controller = controller;
}
#FXML
public void delete(ActionEvent event){
// Your code
controller.refreshTable();
closeStage(event);
}}
And in the Controller:
DialogBoxController dialog = loader.getController();
dialog.editTask(selectedTask);
dialog.setController(this);

Tableview not showing new added data, only shows after restarting program (javafx)

The tableview only shows newly added data when I restart the program.
The steps I follow to add the new item are:
dialogCadastro
Confirm the registry
update the table
However, updating the table does not work.
This is my code:

JavaFX call method in Button with the correst String from List

i am new here, am new in programming and i am trying to create a Java app with Selenium and JavaFX. In this app i should be able to check the links of a page and also could be able to show the pointed link. For the moment the programm can check all the links on a page but it can't show the correct link. I display all urls in a ListView with a button and in this buttons calls the method to show the link but for every button in the list it always shows the same url/link because it is the last value taken from the variable url in a while loop. And also i have 4 tabs where i track the HTTP Status of each link. For all 200 HTTP status they are inserted in the "200s" tab, for the 300 in the "300s" tab, the same for the 400 and 500. I have a variable respCode for the HTTP status but it always displays the last value in the while loop (200). Here is a code snippet to have a look on it:

Could someone please help with these issues?

You don't seem to understand the way ListView works:
A ListView creates the cells that are required to display the items when they are needed. You don't control yourself when this is done. You should be able to deal with cell creation happening at any time. There is no 1:1 relation between cells and items. Items may be reassigned to different cells and there may not be a cell for every item.
For this reason retrieving info in cellFactory (which is what you do in your cell constructor) will not work.
You should change the item type allowing you to access all neccessary info and use the ListCell.item property in the Button handler of the cell:
private static class Response {
private final int responseCode;
private final String url;
Response(int responseCode, String url) {
this.responseCode = responseCode;
this.url = url;
}
// getters...
}
private static class XCell extends ListCell<Response> {
private final HBox hB = new HBox();
private final Label label = new Label("Empty");
private final Button bB = new Button("Show Link");
private final Text response = new Text();
public XCell() {
hB.getChildren().addAll(bB, response, label);
bB.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent eventTwo) {
// handle button click using info from cell item
Response item = getItem();
WebElement linkTwo = driver.findElement(By.xpath("//a[contains(#href, '" + item.getUrl() + "')]"));
scrolltoElement(linkTwo);
HighlightThisLink(driver, linkTwo);
}
});
}
#Override
protected void updateItem(Response item, boolean empty) {
super.updateItem(item, empty);
// update display
if (empty || item == null) {
setGraphic(null);
} else {
label.setText(item.getUrl());
response.setText("("+Integer.toString(item.getResponseCode()) + "):");
setGraphic(hB);
}
}
}
#FXML
private void initialize() {
listTwo = FXCollections.observableArrayList();
ListView<Response> lvTwo = new ListView<>(listTwo);
lvTwo.setCellFactory(lv -> new XCell());
paneTwo.getChildren().add(lvTwo);
listThree = FXCollections.observableArrayList();
ListView<Response> lvThree = new ListView<>(listThree);
lvThree.setCellFactory(l -> new XCell());
paneThree.getChildren().add(lvThree);
listFour = FXCollections.observableArrayList();
ListView<Response> lvFour = new ListView<>(listFour);
lvFour.setCellFactory(l -> new XCell());

JavaFX: How to bind TextField with ObservableList and update those data into tableview?

Trying to make a dictionary using JavaFx.
Here is my Controller class-
public class MainUIController implements Initializable {
DatabaseManager db=new DatabaseManager();
ObservableList<OvidhanMeaning> MeaningList;
#FXML
private TextField searchField;
#FXML
private ImageView searchIcon;
#FXML
private ImageView aboutIcon;
#FXML
private TableView<OvidhanMeaning> ovidhanTable;
#FXML
private TableColumn<OvidhanMeaning, String> englishCol;
#FXML
private TableColumn<OvidhanMeaning, String> banglaCol;
#Override
public void initialize(URL location, ResourceBundle resources) {
Image search = new Image(getClass().getResource("/images/search.png").toString(), true);
Image about = new Image(getClass().getResource("/images/about.png").toString(), true);
//Font bnFont = Font.loadFont(getClass().getResource("/fonts/Siyamrupali.ttf").toExternalForm(), 12);
Font bnFont = Font.loadFont(getClass().getResourceAsStream("/fonts/Siyamrupali.ttf"), 12);
searchIcon.setImage(search);
aboutIcon.setImage(about);
db.Connect("jdbc:sqlite::resource:ankurdb/bn_words.db");
ResultSet rs = db.GetResult("select en_word,bn_word from words");
MeaningList=FXCollections.observableArrayList();
try {
while(rs.next())
{
String enword = rs.getString("en_word");
String bnword = rs.getString("bn_word");
MeaningList.add(new OvidhanMeaning(enword,bnword));
englishCol.setCellValueFactory(new PropertyValueFactory<OvidhanMeaning, String>("enword"));
banglaCol.setCellValueFactory(new PropertyValueFactory<OvidhanMeaning, String>("bnword"));
ovidhanTable.setItems(MeaningList);
}
} catch (SQLException e) {
e.printStackTrace();
}
System.out.println(MeaningList.size());
}
}
And here is my model class in which I loaded the data-
public class OvidhanMeaning {
private SimpleStringProperty enword;
private SimpleStringProperty bnword;
public OvidhanMeaning(String enword, String bnword) {
this.enword = new SimpleStringProperty(enword);
this.bnword = new SimpleStringProperty(bnword);
}
public String getenword() {
return enword.get();
}
public SimpleStringProperty enwordProperty() {
return enword;
}
public String getbnword() {
return bnword.get();
}
public SimpleStringProperty bnwordProperty() {
return bnword;
}
}
Now I'm trying to bind the searchField with the loaded MeaningList and populate the binded data into ovidhanTable.
How can I do this?

Changing TextArea in another class

There is a class FXMLDocumentController.
There is a class ThreadForFile which has been inheriting from class Thread (which I read data from a file)
After I pressed the button (in the class FXMLDocumentController) I create a flow of class ThreadForFile.
I need to in the class ThreadForFile, when reading, the string displayed in the TextArea. But I can not figure out if I pass a parameter TextArea, and change it in the constructor, then there is a change in this component.But if I assign the class field this TextArea, it displays an error :

You are trying to access a JavaFX Control outside the JavaFX Application thread.
Never use your controls, out of your Controller or pass them as a parameter to other methods. Instead, try to pass data to the controller, which in turn will set it to the controls inside the controller.
Some useful links are on passing data to the Controller :
