Getting selected item from a JavaFX TableView
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..
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.

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);
}
});
