Javafx select multiple lines

Question

I am trying to select multiple rows in javafx, but I do not want to use the keyboard (SHIFT) for this.it should be after I click on it, and when I click on another column, it should also be selected.

I check some other answers here, but I could not find something short and comfortable. Is there a shorter way to do this?

@FXML private static Logger logger = Logger.getLogger(MainFrameControl.class); public TableView<Box> boxTable; protected final ObservableList<Box> boxData = FXCollections.observableArrayList(); Service service = new ServiceImpl(); private Stage mainStage; public MainFrameControl(Stage mainStage) { FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("MainFrame.fxml")); fxmlLoader.setRoot(this); fxmlLoader.setController(this); this.mainStage = mainStage; Stage stage = new Stage(); try { fxmlLoader.load(); } catch (IOException exception) { throw new RuntimeException(exception); } ArrayList<Box> list = service.findAllBoxen(); TableColumn<Box, String> boxnameColumn = (TableColumn<Box, String>) boxTable.getColumns().get(0); boxnameColumn.setCellValueFactory(new PropertyValueFactory<Box, String>("boxName")); TableColumn<Box, String> sizeColumn = (TableColumn<Box, String>) boxTable.getColumns().get(1); sizeColumn.setCellValueFactory(new PropertyValueFactory<Box, String>("size")); TableColumn<Box, String> windowColumn = (TableColumn<Box, String>) boxTable.getColumns().get(2); windowColumn.setCellValueFactory(new PropertyValueFactory<Box, String>("window")); TableColumn<Box, String> costColumn = (TableColumn<Box, String>) boxTable.getColumns().get(3); costColumn.setCellValueFactory(new PropertyValueFactory<Box, String>("cost")); TableColumn<Box, String> locationColumn = (TableColumn<Box, String>) boxTable.getColumns().get(4); locationColumn.setCellValueFactory(new PropertyValueFactory<Box, String>("location")); TableColumn<Box, Boolean> beddingColumn = (TableColumn<Box, Boolean>) boxTable.getColumns().get(5); beddingColumn.setCellValueFactory(new PropertyValueFactory<Box, Boolean>("bedding")); boxTable.setItems(boxData); 

Answer 1

 tableView.getSelectionModel().setSelectionMode( SelectionMode.MULTIPLE ); 

Answer 2

This is just a basic idea of ​​what you can look for. It may have improved a bit, but I don't know how to use it.

 import javafx.application.Application; import javafx.beans.property.DoubleProperty; import javafx.beans.property.SimpleDoubleProperty; import javafx.beans.property.SimpleStringProperty; import javafx.beans.property.StringProperty; import javafx.collections.FXCollections; import javafx.collections.ObservableList; import javafx.event.ActionEvent; import javafx.event.EventHandler; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.scene.control.SelectionMode; import javafx.scene.control.TableColumn; import javafx.scene.control.TablePosition; import javafx.scene.control.TableView; import javafx.scene.control.cell.PropertyValueFactory; import javafx.scene.input.MouseEvent; import javafx.scene.layout.VBox; import javafx.stage.Stage; public class TableTest extends Application { @Override public void start(Stage primaryStage) { ObservableList<LineItem> items = FXCollections.observableArrayList(); items.addAll(new LineItem("hello",123.45), new LineItem("paid in full",0.01), new LineItem("paid",0.01), new LineItem("due",0.01), new LineItem("paid",0.01)); ObservableList<LineItem> filteredItems = FXCollections.observableArrayList(items); TableView<LineItem> tableView = new TableView<>(filteredItems); ObservableList<TablePosition> selectedCells = FXCollections.observableArrayList(); Button multi = new Button("Multi-select"); multi.setOnAction(new EventHandler<ActionEvent>() { @Override public void handle(ActionEvent event) { multi.setText((multi.getText().equals("Multi-select"))?"Single-select":"Multi-select"); selectedCells.clear(); } }); TableColumn<LineItem,String> descCol = new TableColumn<>("desc"); descCol.setCellValueFactory(new PropertyValueFactory<>("desc")); TableColumn<LineItem, Double> amountCol = new TableColumn<>("amount"); amountCol.setCellValueFactory(new PropertyValueFactory<>("amount")); tableView.getColumns().addAll(descCol,amountCol); tableView.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE); tableView.getSelectionModel().setCellSelectionEnabled(true); //maybe you want onTouchPressed here for tablet tableView.setOnMousePressed(new EventHandler<MouseEvent>() { @Override public void handle(MouseEvent event) { if (multi.getText().equals("Single-select")) return; selectedCells.add( tableView.getSelectionModel().getSelectedCells().get( tableView.getSelectionModel().getSelectedCells().size()-1 ) ); for (TablePosition tp : selectedCells){ tableView.getSelectionModel().select(tp.getRow(), tp.getTableColumn()); } } }); VBox root = new VBox(); root.getChildren().addAll(tableView, multi); Scene scene = new Scene(root, 300, 300); primaryStage.setTitle("multi select table test"); primaryStage.setScene(scene); primaryStage.show(); } public class LineItem { private final StringProperty desc = new SimpleStringProperty(); private final DoubleProperty amount = new SimpleDoubleProperty(); public StringProperty descProperty() {return desc;} public DoubleProperty amountProperty() {return amount;} public LineItem(String dsc, double amt) { desc.set(dsc); amount.set(amt); } } }

Custom RowFactory is a good solution for this problem:

 boxTable.setRowFactory(new Callback<TableView<Box>, TableRow<Box>>() { @Override public TableRow<Box> call(TableView<Box> tableView2) { final TableRow<Box> row = new TableRow<>(); row.addEventFilter(MouseEvent.MOUSE_PRESSED, new EventHandler<MouseEvent>() { @Override public void handle(MouseEvent event) { final int index = row.getIndex(); if (index >= 0 && index < boxTable.getItems().size()) { if(boxTable.getSelectionModel().isSelected(index)) boxTable.getSelectionModel().clearSelection(index); else boxTable.getSelectionModel().select(index); event.consume(); } } }); return row; } });
