java - 如何在javafx中的TableView中禁用右键单击所选行？

Question

我正在JavaFX中创建TableView。通过单击鼠标左键，我选择一个表行，当我单击鼠标右键时，也会发生同样的情况。我想禁用右键单击而不将焦点放在该行上。我也尝试过:

table.setSelectionModel(null);

我该怎么做？

类TableViewer

public class TableViewer extends Application {
private TableView table = new TableView();
final ObservableList<Person> data = FXCollections.observableArrayList(
        new Person("Jacob", "Smith", "jacob.smith@example.com"),
        new Person("Isabella", "Johnson", "isabella.johnson@example.com"),
        new Person("Ethan", "Williams", "ethan.williams@example.com"),
        new Person("Emma", "Jones", "emma.jones@example.com"),
        new Person("Michael", "Brown", "michael.brown@example.com")
);

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

@Override
public void start(Stage stage) {
    Scene scene = new Scene(new Group());
    stage.setTitle("Table View Sample");
    stage.setWidth(450);
    stage.setHeight(500);

    final Label label = new Label("Address Book");
    label.setFont(new Font("Arial", 20));

    table.setEditable(true);

    TableColumn firstNameCol = new TableColumn("First Name");
    firstNameCol.setMinWidth(100);
    firstNameCol.setCellValueFactory(
            new PropertyValueFactory<Person, String>("firstName"));

    TableColumn lastNameCol = new TableColumn("Last Name");
    lastNameCol.setMinWidth(100);
    lastNameCol.setCellValueFactory(
            new PropertyValueFactory<Person, String>("lastName"));

    TableColumn emailCol = new TableColumn("Email");
    emailCol.setMinWidth(200);
    emailCol.setCellValueFactory(
            new PropertyValueFactory<Person, String>("email"));

    table.setItems(data);
    table.addEventFilter(MouseEvent.MOUSE_CLICKED, e -> {
        if (e.getButton() == MouseButton.SECONDARY) {
            table.getSelectionModel().clearSelection();
        }
    });
    table.getColumns().addAll(firstNameCol, lastNameCol, emailCol);

    final VBox vbox = new VBox();
    vbox.setSpacing(5);
    vbox.setPadding(new Insets(10, 0, 0, 10));
    vbox.getChildren().addAll(label, table);

    ((Group) scene.getRoot()).getChildren().addAll(vbox);

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

人员类别

public class Person {
private final SimpleStringProperty firstName;
private final SimpleStringProperty lastName;
private final SimpleStringProperty email;

public Person(String fName, String lName, String email) {
    this.firstName = new SimpleStringProperty(fName);
    this.lastName = new SimpleStringProperty(lName);
    this.email = new SimpleStringProperty(email);
}

public String getFirstName() {
    return firstName.get();
}

public void setFirstName(String fName) {
    firstName.set(fName);
}

public String getLastName() {
    return lastName.get();
}

public void setLastName(String fName) {
    lastName.set(fName);
}

public String getEmail() {
    return email.get();
}

public void setEmail(String fName) {
    email.set(fName);
}

}

你可以做到

table.setRowFactory(tv -> {
    TableRow<Person> row = new TableRow<>();
    row.addEventFilter(MouseEvent.MOUSE_PRESSED, e -> {
        if (e.getButton() == MouseButton.SECONDARY) {
            e.consume();
        }
    });
    return row ;
});

注意:您应该正确键入表格和列，而不是使用原始类型。 IE。你需要更换

private TableView table = new TableView();

与

private TableView<Person> table = new TableView<>();

和

TableColumn firstNameCol = new TableColumn("First Name");

与

TableColumn<Person, String> firstNameCol = new TableColumn<>("First Name");

等等..
