Question

我正在使用JavaFX，我有一个奇怪的问题。以下代码位于继承Stage的类的构造函数中。代码正在进行中。

    // this works fine, the chart is displayed
    Scene scene = new Scene(lineChart, 1000, 600);
    // table is not shown until I click on the window
    Scene scene = new Scene(bidTable, 1000, 600);

    this.setTitle("Auction chart");
    this.setScene(scene);

我错了什么？单击窗口后，没有显示错误和包含内容的表格。在它只是一个白色的窗口之前。

编辑：我删除了表格中的图表：

public class AuctionChart extends Stage {

    private final TableView<Bid> bidTable = new TableView<Bid>();

    private final TableColumn<Bid, String> bidColumn = new TableColumn<Bid, String>("Bid");

    private final TableColumn<Bid, String> utilityColumn = new TableColumn<Bid, String>("Utility");

    private final TableColumn<Bid, String> profitColumn = new TableColumn<Bid, String>("Profit");

    private final NumberFormat fm = NumberFormat.getCurrencyInstance();

    public AuctionChart() {

        initialize();

        bidTable.getColumns().addAll(bidColumn, utilityColumn, profitColumn);

        Scene scene = new Scene(bidTable, 1000, 600);

        this.setTitle("Auction chart");
        this.setScene(scene);
    }

    public void setTowns(List<Town> towns) {

        bidTable.setItems(FXCollections.observableArrayList(towns.get(0).getGebote()));
    }

    private void initialize() {
        bidColumn.setCellValueFactory(cellData -> new SimpleStringProperty(fm.format(cellData.getValue().getBid())));
        utilityColumn
                .setCellValueFactory(cellData -> new SimpleStringProperty(fm.format(cellData.getValue().getUtility())));
        profitColumn
                .setCellValueFactory(cellData -> new SimpleStringProperty(fm.format(cellData.getValue().getProfit())));
    }
}

启动：

    AuctionChart stage = new AuctionChart();
    stage.setTowns(towns);
    stage.show();

谢谢，这不是JavaFx问题。这是应用程序后端中并发线程的问题。

在单击之前，TableView不可见
