Question

我是一名JavaFX新手，由于某些原因，我的数据并没有显示在桌面视图中。

控制器类：

public class TxstController implements Initializable {

@FXML private Label label;
@FXML private TextField searchBar;
@FXML private Button searchButton;
@FXML private ListView dateList;

@FXML private TableView<Service> serviceTable;
@FXML private TableColumn<Service, Integer> qntColumn;
@FXML private TableColumn<Service, String> descColumn;
@FXML private TableColumn<Service, Double> priceColumn;




@FXML
private void handleSearchButton(ActionEvent event) {
    //do stuff when searchButton get clicked
    List<String> lista = new ArrayList<>();
    lista.add("Queijo");
    lista.add("Azeitonas");
    lista.add("Cebola");
    fillListWith(lista);


}

@FXML
private void textFieldKeyHandler(KeyEvent event){
    if(event.getCode() == KeyCode.ENTER){         
      //do stuff when in text field you click enter
    }
}

private void fillListWith(List<String> list){
    //adds string list at param to dateList
    dateList.setItems(FXCollections.observableList(list));
}

@Override
public void initialize(URL url, ResourceBundle rb) {

 qntColumn.setCellValueFactory(new PropertyValueFactory<>("qnt"));
 descColumn.setCellValueFactory(new PropertyValueFactory<>("desc"));
 priceColumn.setCellValueFactory(new PropertyValueFactory<>("price"));


 ObservableList<Service> lista = FXCollections.observableArrayList();
 lista.add(new Service(3,"Queijo com ",19.30));
 lista.add(new Service(2,"asdasasd",5.21));
 lista.add(new Service(3,"Queijo com ",19.30));
 lista.add(new Service(3,"Queijo com ",19.30));
 lista.add(new Service(3,"Queijo com ",19.30));
 lista.add(new Service(3,"Queijo com ",19.30));

 serviceTable.setItems(lista);

}

服务类：

class Service {

private int qnt;
private String desc;
private double price;

public Service(int qnt,String desc, double price){
    this.qnt = qnt;
    this.desc = desc;
    this.price = price;
}

public int getqnt(){
    return this.qnt;
}

public String getdesc(){
    return this.desc;
}

public double getprice(){
    return this.price;
}

public void setqnt(int qnt){
    this.qnt = qnt;
}

public void setdesc(String desc){
    this.desc = desc;
}

public void setprice(double price){
    this.price = price;
}

FXML文件：

        </columns>
      </TableView>

没有错误，当表格弹出时，我可以选择已填充的行，例如，如果列表有3个对象，我可以选择3行，其他我不能，但是，对于某些行原因，内容没有显示出来。

Answer 1

您在Service中将getter和setter命名为错误。根据camelCase命名约定命名它们：

public void setQnt(int qnt){
    this.qnt = qnt;
}

TableView没有显示内容[JavaFX]
