Javafx选择多行

我试图在javafx中选择多行，但我不想使用键盘（SHIFT）。应该在我点击它之后选择它，当我点击另一列时它也应该被选中。

我在这里检查一些其他的答案，但我找不到简短而方便的东西。有更短的方法吗？

@FXML private static Logger logger = Logger.getLogger(MainFrameControl.class); public TableView boxTable; protected final ObservableList 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 list = service.findAllBoxen(); TableColumn boxnameColumn = (TableColumn) boxTable.getColumns().get(0); boxnameColumn.setCellValueFactory(new PropertyValueFactory("boxName")); TableColumn sizeColumn = (TableColumn) boxTable.getColumns().get(1); sizeColumn.setCellValueFactory(new PropertyValueFactory("size")); TableColumn windowColumn = (TableColumn) boxTable.getColumns().get(2); windowColumn.setCellValueFactory(new PropertyValueFactory("window")); TableColumn costColumn = (TableColumn) boxTable.getColumns().get(3); costColumn.setCellValueFactory(new PropertyValueFactory("cost")); TableColumn locationColumn = (TableColumn) boxTable.getColumns().get(4); locationColumn.setCellValueFactory(new PropertyValueFactory("location")); TableColumn beddingColumn = (TableColumn) boxTable.getColumns().get(5); beddingColumn.setCellValueFactory(new PropertyValueFactory("bedding")); boxTable.setItems(boxData); 

Answer 1

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

Answer 2

这只是您可能正在寻找的基本概念。 可以使用一些改进，但我不清楚预期的用途。

 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 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 filteredItems = FXCollections.observableArrayList(items); TableView tableView = new TableView<>(filteredItems); ObservableList selectedCells = FXCollections.observableArrayList(); Button multi = new Button("Multi-select"); multi.setOnAction(new EventHandler() { @Override public void handle(ActionEvent event) { multi.setText((multi.getText().equals("Multi-select"))?"Single-select":"Multi-select"); selectedCells.clear(); } }); TableColumn descCol = new TableColumn<>("desc"); descCol.setCellValueFactory(new PropertyValueFactory<>("desc")); TableColumn 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() { @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); } } } 

Answer 3

自定义RowFactory是解决此问题的好方法：

 boxTable.setRowFactory(new Callback, TableRow>() { @Override public TableRow call(TableView tableView2) { final TableRow row = new TableRow<>(); row.addEventFilter(MouseEvent.MOUSE_PRESSED, new EventHandler() { @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; } });
