Question

到目前为止，我已经使用Scene Builder构建了这个GUI，我想在我制作的每个TabPane中向TableView添加空行（TextField）。任何帮助，将不胜感激。或者，如果您可以提出一种代替JavaFX的简便方法来完成此任务。

P.S。我是新手。预先感谢。

到目前为止我的代码

Main.java

package sample;

import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.TableView;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

import java.util.Date;

public class Main extends Application {

    Stage window;
    Button button;

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

    @Override
    public void start(Stage primaryStage) throws Exception {
        Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
        window = primaryStage;
        window.setTitle("LOPA Software");

        window.setScene(new Scene(root, 800, 500));
        window.show();
    }
}

Controller.java

package sample;

import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.TableView;
import javafx.scene.control.TreeItem;
import javafx.scene.control.TreeView;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.input.ContextMenuEvent;

import java.awt.event.MouseEvent;
import java.net.URL;
import java.util.ResourceBundle;

public class Controller implements Initializable {

    @FXML
    TreeView<String> treeView;

    @FXML
    TableView tableView;

    Image icon = new Image(
            getClass().getResourceAsStream("/img/icon.png"));
    private MouseEvent mouseEvent;

    @Override
    public void initialize(URL location, ResourceBundle resources) {
        TreeItem<String> root = new TreeItem<>("Project", new ImageView(icon));
        root.setExpanded(true);

        TreeItem<String> compA = new TreeItem<>("Component A", new ImageView(icon));
        TreeItem<String> compB = new TreeItem<>("Component B", new ImageView(icon));
        TreeItem<String> compC = new TreeItem<>("Component C", new ImageView(icon));
        root.getChildren().addAll(compA, compB, compC);
        compA.setExpanded(true);

        TreeItem<String> compA1 = new TreeItem<>("High", new ImageView(icon));
        TreeItem<String> compA2 = new TreeItem<>("Low", new ImageView(icon));
        compA.getChildren().addAll(compA1, compA2);

        treeView.setRoot(root);
    }


    public void mouseClick(javafx.scene.input.MouseEvent mouseEvent) {
        if (mouseEvent.getClickCount() == 2) {
            TreeItem<String> item = treeView.getSelectionModel().getSelectedItem();
            System.out.println(item.getValue());
        }
    }
}

在JavaFX中，如何在TabTane内的TableView中添加TextField？
