javafx Add Button to Tableview


Example

You can add a button or another javafx component to Tableview using column setCellFactory(Callback value) method.

Sample Application

In this application we are going to add a button to TableView. When clicked to this column button, data on the same row as button is selected and its information printed.

In the addButtonToTable() method, cellFactory callback is responsible adding button to related column. We define the callable cellFactory and implement its override call(...) method to get TableCell with button and then this cellFactory set to related column setCellFactory(..) method. In our sample this is colBtn.setCellFactory(cellFactory). SSCCE is below:

import javafx.application.Application;
import javafx.beans.property.SimpleIntegerProperty;
import javafx.beans.property.SimpleStringProperty;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.event.ActionEvent;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.TableCell;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.PropertyValueFactory;
import javafx.stage.Stage;
import javafx.util.Callback;

public class TableViewSample extends Application {

    private final TableView<Data> table = new TableView<>();
    private final ObservableList<Data> tvObservableList = FXCollections.observableArrayList();

    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage stage) {

        stage.setTitle("Tableview with button column");
        stage.setWidth(600);
        stage.setHeight(600);

        setTableappearance();

        fillTableObservableListWithSampleData();
        table.setItems(tvObservableList);

        TableColumn<Data, Integer> colId = new TableColumn<>("ID");
        colId.setCellValueFactory(new PropertyValueFactory<>("id"));

        TableColumn<Data, String> colName = new TableColumn<>("Name");
        colName.setCellValueFactory(new PropertyValueFactory<>("name"));

        table.getColumns().addAll(colId, colName);

        addButtonToTable();

        Scene scene = new Scene(new Group(table));

        stage.setScene(scene);
        stage.show();
    }

    private void setTableappearance() {
        table.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY);
        table.setPrefWidth(600);
        table.setPrefHeight(600);
    }

    private void fillTableObservableListWithSampleData() {

        tvObservableList.addAll(new Data(1, "app1"),
                                new Data(2, "app2"), 
                                new Data(3, "app3"), 
                                new Data(4, "app4"),
                                new Data(5, "app5"));
    }

    private void addButtonToTable() {
        TableColumn<Data, Void> colBtn = new TableColumn("Button Column");

        Callback<TableColumn<Data, Void>, TableCell<Data, Void>> cellFactory = new Callback<TableColumn<Data, Void>, TableCell<Data, Void>>() {
            @Override
            public TableCell<Data, Void> call(final TableColumn<Data, Void> param) {
                final TableCell<Data, Void> cell = new TableCell<Data, Void>() {

                    private final Button btn = new Button("Action");

                    {
                        btn.setOnAction((ActionEvent event) -> {
                            Data data = getTableView().getItems().get(getIndex());
                            System.out.println("selectedData: " + data);
                        });
                    }

                    @Override
                    public void updateItem(Void item, boolean empty) {
                        super.updateItem(item, empty);
                        if (empty) {
                            setGraphic(null);
                        } else {
                            setGraphic(btn);
                        }
                    }
                };
                return cell;
            }
        };

        colBtn.setCellFactory(cellFactory);

        table.getColumns().add(colBtn);

    }

    public class Data {

        private int id;
        private String name;

        private Data(int id, String name) {
            this.id = id;
            this.name = name;
        }

        public int getId() {
            return id;
        }

        public void setId(int ID) {
            this.id = ID;
        }

        public String getName() {
            return name;
        }

        public void setName(String nme) {
            this.name = nme;
        }

        @Override
        public String toString() {
            return "id: " + id + " - " + "name: " + name;
        }

    }
}
