Changing TextArea in another class

Changing TextArea in another class - java

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 :

public void setController(Controller controller){
this.controller = controller;

DialogBoxController dialog = loader.getController();
dialog.editTask(selectedTask);
dialog.setController(this);

JavaFX - How to set value to a textfield inside a tab?

I am trying to set value to a text field which is inside a Tab. I am having multiple tabs and I want to set value to text field inside each tab.
Any idea as to how to set the text for textfield inside the tab?
I am using the below code to update the value for the textfield, but nothing's happening while trying to do the same.
Code:
public class FXMLController {
#FXML
private Button inputXmlFileBtn;
#FXML
private TextField inputXmlName;
#FXML
private TabPane xmlData;
#FXML
private Tab vendorHeaderFb;
#FXML
private TextField vendorHeader1;
Label label;
public String inputXmlFileChooser() throws ParserConfigurationException,
SAXException, IOException, JAXBException {
FileChooser fileChooser = new FileChooser();
// Set extension filter
fileChooser.getExtensionFilters().addAll(
new ExtensionFilter("XML files (*.xml)", "*.xml"));
// Open Dialog
File file = fileChooser.showOpenDialog(null);
String xmlPath = "";
xmlPath = file.getPath();
// Set the path for inputXmlName text field
if (file != null) {
inputXmlName.setText(xmlPath);
}
//Unmarshall
label = this.unmarshallXml();
System.out.println(label.getVendorHeader1());
vendorHeaderFb = new Tab();
vendorHeader1 = new TextField();
vendorHeader1.setText(label.getVendorHeader1());
vendorHeaderFb.setContent(vendorHeader1);
return xmlPath;
}
Updated Code including the Pojo class for FXML.
public class FXMLController {
#FXML
private Button inputXmlFileBtn;
#FXML
private TextField inputXmlName;
#FXML
private TabPane xmlData;
#FXML
private Tab vendorHeaderFb;
#FXML
private TextField VendorHeader1;
Label label;
public String inputXmlFileChooser() throws ParserConfigurationException,
SAXException, IOException, JAXBException {
FileChooser fileChooser = new FileChooser();
// Set extension filter
fileChooser.getExtensionFilters().addAll(
new ExtensionFilter("XML files (*.xml)", "*.xml"));
// Open Dialog
File file = fileChooser.showOpenDialog(null);
String xmlPath = "";
xmlPath = file.getPath();
// Set the path for inputXmlName text field
if (file != null) {
inputXmlName.setText(xmlPath);
}
//Unmarshall
label = this.unmarshallXml();
System.out.println(label.getVendorHeader1());
FXMLProps fxmlProps = new FXMLProps();
fxmlProps.setVendorHeader1(label.getVendorHeader1());
System.out.println(fxmlProps.getVendorHeader1());
VendorHeader1 = new TextField();
VendorHeader1.setText(fxmlProps.getVendorHeader1());
//vendorHeaderFb.setContent(vendorHeader1);
//vendorHeader1.setText(label.getVendorHeader1());
//vendorHeaderFb.setContent(vendorHeader1);
return xmlPath;
}
POJO/Property Class
public class FXMLProps {
private final SimpleStringProperty VendorHeader1 = new SimpleStringProperty(
"");
public FXMLProps() {
}
public FXMLProps(String VendorHeader1) {
setVendorHeader1(VendorHeader1);
}
public String getVendorHeader1() {
return VendorHeader1.get();
}
public void setVendorHeader1(String vH1) {
VendorHeader1.set(vH1);
}
}
I am still not able to set the value for text field vendorHeader1.
Can someone point out what's going wrong?

You have to apply a Binding between the text property of the TextField and the SimpleStringProperty that is used for the value. You will have to make the vendor header property of your FXMLProps public in a way that enables Binding options in other classes:
public class FXMLProps {
private final SimpleStringProperty vendorHeader = new SimpleStringProperty("");
public FXMLProps() {}
public FXMLProps(String vendorHeader) {
setVendorHeader(vendorHeader);
}
public String getVendorHeader() {
return VendorHeader1.get();
}
public void setVendorHeader(String vendorHeaderText) {
vendorHeader.set(vendorHeaderText);
}
// this is needed for the Binding
public final SimpleStringProperty vendorHeaderProperty() {
return vendorHeader;
}
}
Then somewhere in your application (maybe in start()) you need to create the Binding like
// bind those two properties (TextField, SimpleStringProperty)
Bindings.bindBidirectional(vendorHeader1.textProperty(), fxmlProps.vendorHeaderProperty());

adding data into JavaFX tableview

I'm trying to push my data that I'm getting from a RethinkDB into a JavaFx TableView, however, the changes do not appear in the tableview and I can't figure out why.
I'm pretty new to JavaFx so I hope you can help me.
Here are my classes : (I didn't include my memory classes where I save the data from the DB)
RethinkDBConnect class
public class RethinkDBConnect {
public static final RethinkDB r = RethinkDB.r;
GsonConverter con = new GsonConverter();

TicketDataProperty tickdat = new TicketDataProperty(null, null, null, null, null, null);
#FXML private TableView <TicketDataProperty> table;
#FXML private TableColumn <TicketDataProperty,String> key;

beschreibung.setCellValueFactory(new PropertyValueFactory<TicketDataProperty,String>("beschreibung"));
table.setItems(list);
}
}
GsonConverter class
public class GsonConverter {
public JiraTicketBody gson(String json)
{
Gson gson = new Gson();
JiraTicketBody BodyObj = gson.fromJson(json,JiraTicketBody.class);
return BodyObj;
}
}
Main class
public class Main extends Application
{
//ViewXML
#Override
public void start(Stage primaryStage) throws IOException
{
Parent root = FXMLLoader.load(getClass().getResource("/view/ViewXML.fxml"));
Scene scene = new Scene(root);
primaryStage.setTitle("Ticket System Application");
primaryStage.setScene(scene);
primaryStage.sizeToScene();
primaryStage.show();
}
public static void main(String[] args)
{
try {
//ViewXML
launch(args);
RethinkDBConnect obj = new RethinkDBConnect();
obj.Connection();
} catch(Exception e) {
}
}
}

There are two issues with the code you have posted.
As stated in the documentation, Application.launch() blocks until the application exits. So you don't even create the RethinkDBConnection class until the application is in the process of closing. You should consider the start() method to be the entry point to the application, and should have no code other than launch() in the main(...) method. Anything you do in a JavaFX application should be done in the start(...) or init(...) methods, or in methods invoked from there, etc.
In this case, since you don't seem to need RethinkDBConnection from outside the controller, I see no reason not to create RethinkDBConnect from the controller itself.
You need to update the list that belongs to the controller. Instead, you are creating a new object that happens to be the same class as the controller, and updating the list that belongs to that object. Obviously, that list has nothing at all to do with the table. You need to pass a reference to the actual list that is used as the backing list for the table to the RethinkDBController instance.
So your code should look like:
public class RethinkDBConnection {
// public static final RethinkDB r = RethinkDB.r;
// GsonConverter con = new GsonConverter();
// JiraTicketBody body = new JiraTicketBody();
private final ObservableList<TicketDataProperty> dataList ;
public RethinkDBConnection(ObservableList<TicketDataProperty> dataList) {
this.dataList = dataList ;
}
public void connect(){
dataList.add(new TicketDataProperty
("test","test","test","test","test","test"));
}
}
Then in the controller you can do:
public class ViewController implements Initializable {
#FXML private TableView <TicketDataProperty> table;
#FXML private TableColumn <TicketDataProperty,String> key;
#FXML private TableColumn <TicketDataProperty,String> prioritaet;
#FXML private TableColumn <TicketDataProperty,String> erstellt;
#FXML private TableColumn <TicketDataProperty,String> status;
#FXML private TableColumn <TicketDataProperty,String> zustand;
#FXML private TableColumn <TicketDataProperty,String> beschreibung;
private ObservableList<TicketDataProperty> list = FXCollections.observableArrayList(
new TicketDataProperty("example","example","example","example","example","example")
);
#Override
public void initialize(URL location, ResourceBundle resources) {
key.setCellValueFactory(new PropertyValueFactory<TicketDataProperty,String>("key"));
prioritaet.setCellValueFactory(new PropertyValueFactory<TicketDataProperty,String>("prioritaet"));
erstellt.setCellValueFactory(new PropertyValueFactory<TicketDataProperty,String>("erstellt"));
status.setCellValueFactory(new PropertyValueFactory<TicketDataProperty,String>("status"));
zustand.setCellValueFactory(new PropertyValueFactory<TicketDataProperty,String>("zustand"));
beschreibung.setCellValueFactory(new PropertyValueFactory<TicketDataProperty,String>("beschreibung"));
table.setItems(list);
RethinkDBConnection connection = new RethinkDBConnection(list);
connection.connect();
}
}
And your Main class should just be:
public class Main extends Application
{
//ViewXML
#Override
public void start(Stage primaryStage) throws IOException
{
Parent root = FXMLLoader.load(getClass().getResource("/view/ViewXML.fxml"));
Scene scene = new Scene(root);
primaryStage.setTitle("Ticket System Application");
primaryStage.setScene(scene);
primaryStage.sizeToScene();
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
If you really do need access to your RethinkDBConnection instance outside the controller, then modify the controller as follows:
public class ViewController implements Initializable {
#FXML private TableView <TicketDataProperty> table;
#FXML private TableColumn <TicketDataProperty,String> key;
#FXML private TableColumn <TicketDataProperty,String> prioritaet;
#FXML private TableColumn <TicketDataProperty,String> erstellt;
#FXML private TableColumn <TicketDataProperty,String> status;
#FXML private TableColumn <TicketDataProperty,String> zustand;
#FXML private TableColumn <TicketDataProperty,String> beschreibung;
private ObservableList<TicketDataProperty> list = FXCollections.observableArrayList(
new TicketDataProperty("example","example","example","example","example","example")
);
#Override
public void initialize(URL location, ResourceBundle resources) {
key.setCellValueFactory(new PropertyValueFactory<TicketDataProperty,String>("key"));
prioritaet.setCellValueFactory(new PropertyValueFactory<TicketDataProperty,String>("prioritaet"));
erstellt.setCellValueFactory(new PropertyValueFactory<TicketDataProperty,String>("erstellt"));
status.setCellValueFactory(new PropertyValueFactory<TicketDataProperty,String>("status"));
zustand.setCellValueFactory(new PropertyValueFactory<TicketDataProperty,String>("zustand"));
beschreibung.setCellValueFactory(new PropertyValueFactory<TicketDataProperty,String>("beschreibung"));
table.setItems(list);
}
public ObservableList<TicketDataProperty> getDataList() {
return list ;
}
}
and use this version of Main:
public class Main extends Application
{
//ViewXML
#Override
public void start(Stage primaryStage) throws IOException
{
FXMLLoader loader = new FXMLLoader(getClass().getResource("/view/ViewXML.fxml"));
Parent root = loader.load();
ViewController controller = loader.getController();
RethinkDBConnection connection = new RethinkDBConnection(controller.getDataList());
connection.connect();
Scene scene = new Scene(root);
primaryStage.setTitle("Ticket System Application");
primaryStage.setScene(scene);
primaryStage.sizeToScene();
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Note that I renamed some classes and methods to adhere to standard naming conventions.

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?

One of the TableColumn doesn't show the values but others work fine. JavaFX

I have a TableView with three TableColumns. There is an ObservableList named "sensorDataList " in MainApp.java that stores the objects to be shown in the TableView. With the following code, only the first TableColumn named "idColumn" doesn't show the values from the observable list, however, the other two TableColumns works fine.
MainApp.java (this has an "ObservableList" of Sensor objects (see Sensor.java). Also this class has the method named "showSensorDialog()" which loads the .fxml file that has the TableView in question. FYI, this method is invoked by a button in other controller.)
public class MainApp extends Application {
private Stage primaryStage;
private Stage sensorDialogStage;
private ObservableList<sensor> sensorDataList = FXCollections.observableArrayList();
public MainApp(){
sensorDataList.add(new sensor("testText","1 1 0.7", "0 0 1"));
}
public ObservableList<Sensor> getSensorDataList(){return sensorDataList;}
public void showSensorDialog() {
try {
FXMLLoader loader = new FXMLLoader(MainApp.class.getResource("/view/SensorDialog.fxml"));
Object object = loader.load();
sensorDialogStage = new Stage();
Scene scene = new Scene((Parent) object);
sensorDialogStage.setScene(scene);
SensorDialogController controller = loader.getController();
controller.setSensorDialogStage(sensorDialogStage);
controller.setMainApp(this); // this line connects the ObservableList to the TableView.
sensorDialogStage.showAndWait();
} catch (IOException e) {}
}
}
SensorDialogController.java
public class SensorDialogController implements Initializable {
#FXML
private TableView<Sensor> sensorTable;
#FXML
private TableColumn<Sensor, String> idColumn;
#FXML
private TableColumn<Sensor, String> locationColumn;
#FXML
private TableColumn<Sensor, String> directionColumn;
private MainApp mainApp;
public void setMainApp(MainApp mainApp) {
this.mainApp = mainApp;
sensorTable.setItems(mainApp.getSensorDataList()); // ObservableList and TableView gets connected.
}
#Override
public void initialize(URL url, ResourceBundle rb){
idColumn.setCellValueFactory(new PropertyValueFactory<Sensor, String>("id"));
locationColumn.setCellValueFactory(new PropertyValueFactory<Sensor, String>("location"));
directionColumn.setCellValueFactory(new PropertyValueFactory<Sensor, String>("direction"));
}
}
Sensor.java
public class Sensor{
private SimpleStringProperty id;
private SimpleStringProperty location;
private SimpleStringProperty direction;
public Sensor(String i, String loc, String dir){
this.id = new SimpleStringProperty(i);
this.location = new SimpleStringProperty(loc);
this.direction = new SimpleStringProperty(dir);
}
}
