I have a 2 columns TableView that I would like to use to display a content of Map (Key, Value).
The issue is that nothing is getting displayed in the TableView.
#FXML
private TableView tv;
#FXML
private TableColumn<Map.Entry<Integer, String>, Integer> tcKey;
#FXML
private TableColumn<Map.Entry<String, String>, String> tcValue;
ObservableMap<Integer, String> map;
ObservableList<Map.Entry<Integer, String>> observableList;
int i = 0;
#FXML
private void handleButtonAction(ActionEvent event) {
map.put(i++, "value" + i++);
for (Map.Entry<Integer, String> entry : map.entrySet()) {
System.out.println("Key: " + entry.getKey() + " Value: " + entry.getValue());
}
}
#Override
public void initialize(URL url, ResourceBundle rb) {
map = FXCollections.observableHashMap();
observableList = FXCollections.observableArrayList(map.entrySet());
tv.setItems(observableList);
tv.getColumns().setAll(tcKey, tcValue);
}
}
These definitions are definitely wrong.
#FXML
private TableColumn<Map.Entry<Integer, String>, String> tcKey;
#FXML
private TableColumn<Map.Entry<String, String>, String> tcValue;
I would assume the correct definition is:
#FXML
private TableColumn<Map.Entry<Integer, String>, Integer> tcKey;
#FXML
private TableColumn<Map.Entry<Integer, String>, String> tcValue;
Do note that although you are using ObservableList and ObservableMap, the actual result would be that the table would not respond to any changes in the ObservableMap. If you are expecting the map to change during runtime, then you must do more than this (by using MapChangeListener).

I'm trying to do some reports by hiding some rows from a tableview (I made in scenebuilder) by using a checkbox. If the object from tableview doesn't have in the column a specific String, it becomes invisible. example: By clicking the checkbox, hide all rows that dont have the exact value "Barcelona" in table_adress. I tried to do this, but I keep complicating myself. Any ideas?
the function
#FXML
void CakeRequestsFromBarcelona(ActionEvent event) throws IOException {
for(Object cake:table.getItems()) {
for (TableColumn column : table.getColumns()) {
//not sure how to write it
}
}
}
initialize
#FXML
private TableColumn<CakeRequest, Integer> table_ID;
#FXML
private TableColumn<CakeRequest, String> table_adress;
#FXML
private TableColumn<CakeRequest, String> table_design;
#FXML
private TableColumn<CakeRequest, String> table_flavour;
#FXML
private TableColumn<CakeRequest, String> table_model;
#FXML
private TableColumn<CakeRequest, String> table_name;
#FXML
private TableColumn<CakeRequest, String> table_phonenumber;
#FXML
private TableView<CakeRequest> table;
public void initialize(){
//cakeRequest
table_ID.setCellValueFactory(
p-> new SimpleIntegerProperty(p.getValue().getID()).asObject()
);
table_name.setCellValueFactory(
p -> new SimpleStringProperty(p.getValue().getOwnerName())
);
table_adress.setCellValueFactory(
p -> new SimpleStringProperty(p.getValue().getOwnerAddress())
);
table_phonenumber.setCellValueFactory(
p -> new SimpleStringProperty(p.getValue().getPhoneNumber())
);
table_flavour.setCellValueFactory(
p -> new SimpleStringProperty(p.getValue().getFlavour())
);
table_design.setCellValueFactory(
p -> new SimpleStringProperty(p.getValue().getDesign())
);
table_model.setCellValueFactory(
p -> new SimpleStringProperty(p.getValue().getModel())
);
}
CakeRequest
public class CakeRequest implements Identifiable<Integer>, Serializable{
private int ID;
private String OwnerName;
private String OwnerAddress;
private String PhoneNumber;
private String Model;
private String Flavour;
private String Design;
Use a FilteredList and change the predicate when the check box is checked/unchecked:
private ObservableList<CakeRequest> data = FXCollections.observableArrayList();
private FilteredList<CakeRequest> filteredData = new FilteredList<>(data, request -> true);
public void initialize(){
// existing code...
table.setItems(filteredData);
}
#FXML
void cakeRequestsFromBarcelona(ActionEvent event) {
if (checkBox.isChecked()) {
filteredData.setPredicate(request -> request.getOwnerAddress().contains("Barcelona"));
} else {
filteredData.setPredicate(request -> true);
}
}
I have two classes Customer and Product.i stored this class values in database as a two table one for customer other for product. i use inner join for retrieve this data.i want to show this data in JavaFX TreeTable.there is plenty of tutorial but they only works for one class.this my code so far but it not working.im not javaFX pro.
Connection con;
PreparedStatement ps;
ResultSet rs;
#FXML

} catch (SQLException e) {
System.out.println("GET DATA TO TABLE ERROR");
e.printStackTrace();
}
try {
while(rs.next()){
//pData.add(rs.getString(1),rs.getString(2),rs.getString(3),rs.getString(4),rs.getString(5),rs.getInt(6),rs.getString(7),rs.getString(8),rs.getDate(9));
cData.add(new Customer(rs.getString(1),rs.getString(2),rs.getString(3)));
pData.add(new Product (rs.getString(4),rs.getString(5),rs.getInt(6),rs.getString(7),rs.getString(8),rs.getDate(9)));
}
} catch (SQLException e) {
System.out.println("RS.Next() Error");
e.printStackTrace();
}
cname.setCellValueFactory(new PropertyValueFactory<Customer,String>("customerNam"));
cnic.setCellValueFactory(new PropertyValueFactory<Customer,String>("nic"));
cphone.setCellValueFactory(new PropertyValueFactory<Customer,String>("phone"));
pbrand.setCellValueFactory(new PropertyValueFactory<Product,String>("brand"));

}
So I have the following code:
public class ToDoListController implements Initializable {
String text = "";
LocalDate isoDate;
#FXML
private Button bttnAddEvent;
#FXML
private DatePicker pickerDate;
#FXML
private ComboBox<String> eventsSelector;
#FXML
private Button bttnDone;
#FXML
private Button bttnRemove;
#FXML
private TableView<EventsBean> eventsTable;
#FXML
private TableColumn<EventsBean, String> eventCol;
#FXML
private TableColumn<EventsBean, LocalDate> dateCol;
#FXML
private TableColumn<?, ?> doneCol;
#FXML
private TableColumn<?, ?> observationCol;
#FXML
private TableColumn<?, ?> removeCol;
#FXML
void bttnDoneAction(ActionEvent event) {
}
#FXML
void bttnRemoveAction(ActionEvent event) {
}
#FXML
void pickerDateAction(ActionEvent event) {
isoDate = pickerDate.getValue();
}
ObservableList<EventsBean> dataList =
FXCollections.observableArrayList();
#Override
public void initialize(URL location, ResourceBundle resources) {
System.out.println("The pane loaded");
List<String> myList;
try {
myList = Files.lines(Paths.get("src/com/todolist/EventsList.txt")).collect(Collectors.toList());
eventsSelector.setItems(FXCollections.observableArrayList(myList));
} catch (IOException e) {
System.out.println("Don t find file");
}
eventCol.setCellValueFactory(new PropertyValueFactory<EventsBean, String>("event"));
dateCol.setCellValueFactory(new PropertyValueFactory<EventsBean, LocalDate>("date"));
observationCol.setCellValueFactory(new PropertyValueFactory<EventsBean, String>("observation"));
observationCol.setCellFactory(TextFieldTableCell.<EventsBean>forTableColumn());
observationCol.setOnEditCommit(
(CellEditEvent<EventsBean, String> t) -> {
((EventsBean) t.getTableView().getItems().get(
t.getTablePosition().getRow())
).setObservation(t.getNewValue());
});
observationCol.setSortable(false);
eventsTable.setItems(dataList);
eventsTable.setEditable(true);
bttnAddEvent.setOnAction((ActionEvent e) -> {
text = eventsSelector.getValue().toString();
dataList.add(new EventsBean(text, isoDate, ""));
});
}
}
and my EventsBean class:
public class EventsBean {
private SimpleStringProperty observation;
private SimpleStringProperty event;
private SimpleObjectProperty<LocalDate> date;
public EventsBean(String event, LocalDate date, String observation) {
this.event = new SimpleStringProperty(event);
this.date = new SimpleObjectProperty<LocalDate>(date);
this.observation = new SimpleStringProperty(observation);
}
public String getEvent() {
return event.get();
}
public LocalDate getDate() {
return date.get();
}
public String getObservation() {
return observation.get();
}
public void setObservation(String observation) {
this.observation.set(observation);
}
}
As you can see, I populate the ComboBox with data from a text file.
So I want to use Button bttnAddEvent to add a selected data from ComboBox in TableColumn <?,?> eventCol. Beside this, another challenge it is to use the same Button bttnAddEvent in the same time with data from ComboBox to add the selected date from DatePicker pickerDate in TableColumn <?,?> dateCol.
Update: Until now I put the value of ComboBox into a String named text, but how to transfer into TableColumn eventCol this value from text?
Thank you very much!
I've found the solution and updated the code for someone who will meet this need.
I've a simple question but I'm stuck with it since hours.
I have a Class UnitMap which extends HashMap
And a Class AttackCommand which contains an UnitMap units = new UnitMap();
I'm attempting to display the value of a MapEntry in my TableView:
#FXML
private TableColumn<AttackCommand, Integer> columnlkav;
#FXML
private TableColumn<AttackCommand, Integer> columnstart;
#FXML
private TableView<AttackCommand> tableview;
#FXML
private TableColumn<AttackCommand, String> columnname;
#FXML
private TableColumn<AttackCommand, Point> columntarget;
private ObservableList<AttackCommand> tableData = FXCollections.observableArrayList();
#Override
public void initialize(URL location, ResourceBundle resources) {
AttackCommand ac = new AttackCommand();
ac.getUnits().put(ConstantsUnit.UNIT_ID_LKAV, 5);
ac.setName("Testname");
tableData.add(ac);
columnname.setCellValueFactory(new PropertyValueFactory<AttackCommand, String>("name"));
columnlkav.setCellValueFactory(new PropertyValueFactory<AttackCommand, Integer>("units"));
tableview.setEditable(true);
columnname.setEditable(true);
tableview.setItems(tableData);
}
So the shown entry in the TableColumn is logically {2=5}, because ConstantsUnit.UNIT_ID_LKAV = 2
How can i display the value proper? I tried a few examples from the net but don't get it
By the way: I don't use SimpleStringProperty for name and don't use other Property Classes in AttackCommand because I want to serialize the Data via EclipseLink to my DerbyDB.
My application contains a tabpane, each tab is a nested fxml with controller included.
Each fxml file have a tableview that retrieve data from a microsoft access database.
Some of the tables that only have string columns work and get populated but another one(Demandes) that have a integer column and a localdate column wont populate.and i don't know what's causing the problem.
here the nested controller of "Demandes" tab:
public class DemandesController{
#FXML
private TableView<Demande> demandesTable;
#FXML
private TableColumn<Demande, Integer> numColumn;
#FXML
private TableColumn<Demande, String> societeColumn;
#FXML
private TableColumn<Demande, LocalDate> dateDemandeColumn;
#FXML
private TableColumn<Demande, LocalDate> dateSignatureColumn;
#FXML
private TableColumn<Demande, String> villeColumn;
private ObservableList<Demande> demandes = FXCollections.observableArrayList();
private MainApp mainApp;
String BD_URL = mainApp.getBdUrl();
public DemandesController(){
}
public ObservableList<Demande> getBulletins(){
return demandes;
}
#FXML
private void initialize() {
getDemandesData();
numColumn.setCellValueFactory(cellData -> cellData.getValue().numDemandeProperty().asObject());
societeColumn.setCellValueFactory(cellData -> cellData.getValue().societeProperty());
dateDemandeColumn.setCellValueFactory(cellData -> cellData.getValue().dateDemandeProperty());
dateSignatureColumn.setCellValueFactory(cellData -> cellData.getValue().dateSignatureProperty());
villeColumn.setCellValueFactory(cellData -> cellData.getValue().villeProperty());
}
public void setMainApp(MainApp mainApp){
this.mainApp = mainApp;
demandesTable.setItems(getBulletins());
}
public void getDemandesData(){
Task task = new Task<Void>() {
#Override
protected Void call() throws Exception {
try (Connection con = DriverManager.getConnection(BD_URL)) {
Statement stmt = con.createStatement();
ResultSet res = stmt.executeQuery("SELECT * FROM [Demandes-tab]");
while (res.next()) {
int numDemande = res.getInt(1);
String societe = res.getString(2);
LocalDate dateDemande = res.getDate(3)
.toInstant().atZone(ZoneId.systemDefault()).toLocalDate();
LocalDate dateSignature = res.getDate(4)
.toInstant().atZone(ZoneId.systemDefault()).toLocalDate();
String ville = res.getString(5);
demandes.add(new Demande(numDemande,societe,dateDemande,
dateSignature,ville));
}
}return null;
}
};
new Thread(task).start();
} }
and the parent controller that initialise the nested fxmls and controllers :
public class TabsController{
private MainApp mainApp;
#FXML private AnchorPane Bulletins;
#FXML private BulletinsController BulletinsController;
#FXML private AnchorPane Demandes;
#FXML private DemandesController DemandesController;
#FXML private AnchorPane Personneltest;
#FXML private PersonnelController PersonneltestController;
#FXML private AnchorPane Personnel;
#FXML private PersonnelController PersonnelController;
#FXML private AnchorPane Produit;
#FXML private ProduitController ProduitController;
#FXML private AnchorPane Societes;
#FXML private SocietesController SocietesController;
#FXML
private void initialize() {
}
public void setMainApp(MainApp mainApp) {
this.mainApp = mainApp;
BulletinsController.setMainApp(mainApp);
PersonneltestController.setMainApp(mainApp);
DemandesController.setMainApp(mainApp);
} }
also this was added in the right place :
<Tab text="Demandes">
<content>
<fx:include fx:id="Demandes" source="Demandes.fxml" />
</content>
</Tab>
if someone can tell me why the tableview won't populate that will be a big help. thank you.
ps: oh also i removed the database url just to see if it matters and nothing changed. does that mean that it doesn't connect to the database at all?
