controlfx TableFilter - 动态添加行不会被过滤

Question

我正在使用 controlfx TableFilter 属性来实现 javafx tableview 的过滤器功能。效果很好。但是，一旦将过滤器应用于特定列，并且动态添加新行时，该行就不会被过滤。或者换句话说，列值会自动添加到该列的过滤器中。预期的行为是添加的行也应该根据定义的过滤器进行过滤。 PFA 演示问题的示例代码

import org.controlsfx.control.table.TableFilter;
import org.controlsfx.control.table.TableFilter.Builder;
import javafx.application.Application;
import javafx.beans.property.SimpleStringProperty;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.geometry.Insets;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.PropertyValueFactory;
import javafx.scene.layout.VBox;
import javafx.scene.text.Font;
import javafx.stage.Stage;

public class TableViewSample extends Application {

    private TableView<Person> table = new TableView<Person>();
    private final ObservableList<Person> data = FXCollections.observableArrayList(
            new Person("aaJacob", "Smith", "[email protected]"),
            new Person("aaIsabella", "Johnson", "[email protected]"),
            new Person("aaEthan", "Williams", "[email protected]"),
            new Person("Emma", "Jones", "[email protected]"),
            new Person("Michael", "Brown", "[email protected]"));

    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.getColumns().addAll(firstNameCol, lastNameCol, emailCol);

        Builder<Person> builder = TableFilter.forTableView(this.table);
        builder.apply();

        Button button = new Button("Add Row");
        button.setOnAction((event) -> {
            Person person = new Person("Jacob", "Smith", "[email protected]");
            System.out.println("Data is :" + data);
            data.add(person);
        });

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

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

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

    public static class Person {

        private final SimpleStringProperty firstName;
        private final SimpleStringProperty lastName;
        private final SimpleStringProperty email;

        private 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);
        }

        @Override
        public String toString() {
            return "Person [firstName=" + firstName + ", lastName=" + lastName + ", email=" + email + "]";
        }

    }
}

Answer 1

我也有同样的问题。也许controlsfx 的TableFilter 中存在某种错误。我通过以编程方式创建表格视图得到了解决方案。在 TableView 中添加所有 TableColumns 后应应用过滤器。如果您以编程方式创建表视图，则可以自由动态添加列。

不要对 TableColumns 应用过滤器。相反，在 TableView 上应用过滤器。

TableFilter.forTableView(my_table_view).apply();

Answer 2

你也必须在

table.setItems(data);

之后打电话
