Question

我无法运行JavaFX应用程序。我只想将一些数据存储到表中并查看它。但我只是有错误，有人请帮助我。 这是我的控制器类

import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.PropertyValueFactory;

import java.net.URL;
import java.util.ResourceBundle;

public class Controller implements Initializable {
    @FXML
    TableView<Person> table;
    @FXML
    TableColumn<Person,Integer> number;
    @FXML
    TableColumn<Person,String> name;
    @FXML
    TableColumn<Person,String> surname;


    @Override
    public void initialize(URL location, ResourceBundle resources) {
            table = new TableView<>();
            number = new TableColumn<>();
            name = new TableColumn<>();
            surname = new TableColumn<>();

            number.setCellValueFactory(new PropertyValueFactory<Person, Integer>("id"));
            name.setCellValueFactory(new PropertyValueFactory<Person, String>("name"));
            surname.setCellValueFactory(new PropertyValueFactory<Person, String>("surname"));
            ObservableList<Person> data = FXCollections.observableArrayList(new Person(1,"fa","fafe"));
            table.setItems(data);
            table.getColumns().addAll(number,name,surname);



    }
}

但我收到的错误是我从终端获得的错误，我将每个ID都提供给我的组件

这是错误只是在我的终端中发生。它可能是错的，请帮我解决这个问题。我只想将一些数据存储到我的表中，然后在应用程序中查看结果。

Answer 1

欢迎来到Stack Overflow！

错误信息中的重要一行是：

Caused by: javafx.fxml.LoadException: Error resolving onEditStart='#click', either the event handler is not in the Namespace or there is an error in the script.
/D:/work%20proyeqt%20immidetely/WorkWithTable/out/production/WorkWithTable/sample/sample.fxml:15

这意味着sample.fxml第15行出现错误，特别是onEditStart='#click'。它无法解析'onEditStart'或click（）不是控制器中的函数。

Answer 2

Caused by: javafx.fxml.LoadException: Error resolving onEditStart='#click', either the event handler is not in the Namespace or there is an error in the script.
/D:/work%20proyeqt%20immidetely/WorkWithTable/out/production/WorkWithTable/sample/sample.fxml:15

可能您的按钮上具有click方法，但您的控制器类中没有该方法
