如何填充TableView單元格 - 使用場景生成器

Question

我是Java和Java FX和場景生成器的新手。我把一個TabPane放到一個BorderPane中，現在我試圖填充TableView中的值，並將其放入到TabPane中。我有2個類，Player類和PlayerList類。只會填充物品從某處後，像這樣：

public class PlayerList { 

    ObservableList<Player> playerList; 

    public PlayerList() { 
     getPlayersFromServer(); 
    } 

    private getPlayersFromServer() { 
     this.playerList = FXCollections.observableArrayList(
     new Player("freakyy85","Owner"); 
     new Player("Ky3ak","Owner"); 
     ); 
    } 
} 

現在，我該如何填充使用這樣的事情的TableView行：

nickColumn.setCellValueFactory(
    new PropertyValueFactory<Player,String>("nick") 
); 
groupColumn.setCellValueFactory(
    new PropertyValueFactory<Player,String>("group") 
); 

我第一次不知道該怎麼做，在哪裏做使用場景生成器，因爲我沒有一個fx：id集。現在我有一套，但我根本不知道該怎麼做。

月Player類看起來是這樣的：

public class Player { 
    private SimpleStringProperty nick; 
    private SimpleStringProperty group; 

    public Player (String nick, String group) { 
     this.nick = new SimpleStringProperty(nick); 
     this.group = new SimpleStringProperty(group); 
    } 

    public String getNick() { 
     return nick.get(); 
    } 

    public String getGroup() { 
     return group.get(); 
    } 

    public void setNick (String nick) { 
     this.nick.set(nick); 
    } 

    public void setGroup (String group) { 
     this.group.set(group); 
    } 
}

    @FXML 
    private TableColumn<?, ?> groupColumn; 

    @FXML 
    void handleTextChanged(InputMethodEvent event) { 

    } 

    @FXML 
    void initialize() { 
     assert nickColumn != null : "fx:id=\"nickColumn\" was not injected: check your FXML file 'FXMLDocument.fxml'."; 
     assert groupColumn != null : "fx:id=\"groupColumn\" was not injected: check your FXML file 'FXMLDocument.fxml'."; 

    } 
}

Answer 1

您需要更改該場景生成器提供爲表列的類型（它沒有辦法確定表的類型和列）：

@FXML 
private TableColumn<Player, String> nickColumn; 

@FXML 
private TableColumn<Player, String> groupColumn; 

然後只需將調用setCellValueFactory(...)，你有他們在initialize()方法。所以你最終與

package uctool; 

import java.net.URL; 
import java.util.ResourceBundle; 
import javafx.fxml.FXML; 
import javafx.scene.control.TableColumn; 
import javafx.scene.input.InputMethodEvent; 

public class FXMLDocumentController { 

    @FXML 
    private ResourceBundle resources; 

    @FXML 
    private URL location; 

    @FXML 
    private TableColumn<Player, String> nickColumn; 

    @FXML 
    private TableColumn<Player, String> groupColumn; 

    @FXML 
    void handleTextChanged(InputMethodEvent event) { 

    } 

    @FXML 
    void initialize() { 
     assert nickColumn != null : "fx:id=\"nickColumn\" was not injected: check your FXML file 'FXMLDocument.fxml'."; 
     assert groupColumn != null : "fx:id=\"groupColumn\" was not injected: check your FXML file 'FXMLDocument.fxml'."; 

     nickColumn.setCellValueFactory(
      new PropertyValueFactory<Player,String>("nick") 
     ); 
     groupColumn.setCellValueFactory(
      new PropertyValueFactory<Player,String>("group") 
     ); 
    } 
}
