Getting selected item from a JavaFX TableView

Question

How do I get the selected item from a TableView in JavaFX?

I am currently using

ObservableList selectedItems = taview.getSelectionModel().getSelectedItems();

but that does not return me the one selected item in the selection model.

Answer 1

Ok, lets say you have a data model class named Person. This way:

Person person = taview.getSelectionModel().getSelectedItem();
System.out.println(person.getName());    

Note that TableView must take a Person as a type argument to avoid casting:

@FXML
private TableView<Person> taview;

or

TableView<Person> taview = new TableView<>();

when your row is selected, you will return one Person instance. Then do what ever you want with that instance.

Answer 2

    tableview.getSelectionModel().selectedItemProperty().addListener(new ChangeListener() {
    @Override
    public void changed(ObservableValue observableValue, Object oldValue, Object newValue) {
        //Check whether item is selected and set value of selected item to Label
        if(tableview.getSelectionModel().getSelectedItem() != null) 
        {    
           TableViewSelectionModel selectionModel = tableview.getSelectionModel();
           ObservableList selectedCells = selectionModel.getSelectedCells();
           TablePosition tablePosition = (TablePosition) selectedCells.get(0);
           Object val = tablePosition.getTableColumn().getCellData(newValue);
           System.out.println("Selected Value" + val);
         }
         }
     });

Using this code you can get the selected value from JAVAFX TABLEVIEW Cell.

Thanks..

Here is my try for a cell selection change listener (even if row doesn’t change), inspired by @Java Man's code:

tableView.getSelectionModel().setCellSelectionEnabled(true);
ObservableList selectedCells = tableView.getSelectionModel().getSelectedCells();

selectedCells.addListener(new ListChangeListener() {
    @Override
    public void onChanged(Change c) {
        TablePosition tablePosition = (TablePosition) selectedCells.get(0);
        Object val = tablePosition.getTableColumn().getCellData(tablePosition.getRow());
        System.out.println("Selected Value" + val);
    }
});

Answer 4

For single item selection...

Product p = taview.getSelectionModel().getSelectedItem();
System.out.println(p.getName()); 

For multiple item selection...

ArrayList<Product> p = new ArrayList<>(taview.getSelectionModel().getSelectedItems());
for (Product res : p) {     
    System.out.println(res.getName());      
}

Answer 5

you can get data from tableview like that

For One ItemSelection

`tableview_obj.getSelectionModel().getSelectedItem().yourgetterobjectname`

and Mulltiple Item Selection

tableview_obj.getSelectionModel().getSelectedItems().get(indexNo).yourgetterobjectname

Answer 6

you can use this method maybe it works for you

ObservableList rowList = (ObservableList) tblView.getItems().get(getIndex());

and for the call method will be like that

String email = rowList.get(1).toString();
String contact = rowList.get(2).toString();
String name= rowList.get(0).toString();

Answer 7

if you have a Bean class named Employee.

Employee employee= tblView.getSelectionModel().getSelectedItem();
txtEmployeeName.setText(employee.getName());
