JavaFX FXML表;为什么我的数据不显示

我正在尝试使用FXML创建一个简单的表。该表显示正常,但它不显示我的数据。这是我的主要计划。

public final class TableTest extends Application {

    @Override
    public void start(final Stage primaryStage) {
       URL fxml = ClassLoader.getSystemClassLoader().getResource("Table.fxml");
        FXMLLoader fxmlLoader = new FXMLLoader(fxml);
        TableController tableController = new TableController();
        fxmlLoader.setController(tableController);
        try {
            Pane rootPane = (Pane) fxmlLoader.load();
            Scene scene = new Scene(rootPane);
            primaryStage.setScene(scene);
            primaryStage.show();
       } catch (IOException e) {
           e.printStackTrace();
       }
    }

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

这是FXML。

<?xml version="1.0" encoding="UTF-8"?>

<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.paint.*?>

<BorderPane prefHeight="400.0" prefWidth="600.0" xmlns:fx="http://javafx.com/fxml">
  <center>
    <TableView fx:id="table">
      <columns>
        <TableColumn text="Column 1" fx:id="col1" minWidth="80.0" />
        <TableColumn text="Column 2" fx:id="col2" minWidth="80.0" />
      </columns>
    </TableView>
  </center>
</BorderPane>

这是控制器。

public final class TableController implements Initializable {

    @FXML
    private TableView<TableData> table;
    @FXML
    private TableColumn<TableData, String> col1;
    @FXML
    private TableColumn<TableData, String> col2;

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

        final ObservableList<TableData> data = FXCollections.observableArrayList(
                new TableData("C1R1", "C2R1"),
                new TableData("C1R2", "C2R2")
        );
        table.setItems(data);

        col1.setCellValueFactory(
                new PropertyValueFactory<TableData, String>("col1Property"));
        col2.setCellValueFactory(
                new PropertyValueFactory<TableData, String>("col2Property"));
        table.getColumns().setAll(col1, col2);
    }

    private final class TableData {

        private StringProperty col1Property = new SimpleStringProperty();
        private StringProperty col2Property = new SimpleStringProperty();

        public TableData(final String col1, final String col2) {
            col1Property.set(col1);
            col2Property.set(col2);
        }

        public void setCol1(final String col1) {
            col1Property.set(col1);
        }

        public String getCol1() {
            return col1Property.get();
        }

        public StringProperty col1Property() {
            return col1Property;
        }

        public void setCol2(final String col2) {
            col2Property.set(col2);
        }

        public String getCol2() {
            return col2Property.get();
        }

        public StringProperty col2Property() {
            return col2Property;
        }
    }
}

谁能告诉我我错过了什么?

答案 0 :(得分:1)

你没有遗漏任何东西!事实上,你有太多的东西:

new PropertyValueFactory<TableData, String>("col1Property"));

构造函数参数应该是相关属性的变量名的字符串值,最后没有“Property” - 即,在此示例中只是“col1”。
