Question

我创建了一个简单的GUI，使用JavaFX和fxml。该程序的一部分是使用fxml和其他生成动态GUI。所以，我用fxml创建了javafx.scene.controller.Accordion并在其中添加了代码：

@FXML
Accordion accordionPlant;


public void init(){

    accordionPlant.getPanes().add(createTitledPanePlant(1));
    accordionPlant.getPanes().add(createTitledPanePlant(2));
}

protected TitledPane createTitledPanePlant(int index){

    TilePane tile = new TilePane(Orientation.HORIZONTAL, 5, 5);
    Label typeLabel = new Label("Тип выпуска");
    TextField typeText = new TextField();
    VBox typeContainer = new VBox(typeLabel,typeText);

    Label bankLabel = new Label("Берег");
    Tooltip.install(bankLabel, new Tooltip("Берег, с которого производится выпуск"));
    TextField bankText = new TextField();
    VBox bankContainer = new VBox(bankLabel,bankText);

    tile.getChildren().addAll(typeContainer, bankContainer);

    TitledPane titledPane = new TitledPane("Параметры выпуска " + index, tile);

    return titledPane;
}

在该用户点击按钮后，程序应找到所有TextField并计算其值。那么它必须如何正确或舒适地完成？

我试图获得手风琴的所有窗格：

void test(){
    for (TitledPane pane: accordionPlant.getPanes()) {
        pane.getChildrenUnmodifiable().get(0); //blah, blah
    }
}

但我认为这不是一个好主意，尤其是使用索引。我只需要文本字段。 implements of有什么方法吗？

如果您有动态元素，为什么不在创建它们时将它们存储在MyController.php on line 326: Account {#773 ▼ +__isInitialized__: false -id: 1 -username: null -email: null -emailIsPublic: 0 -password: null -avatar: null -biography: null -level: 1 -registerDate: null -strips: null #slug: null …2 }中？这样你就不必尝试从容器中获取它们。您可能只对List感兴趣，但我发布了整个应用程序。如果您查看Controller，就可以看到我将createTitledPanePlant添加到TextFields - ＆gt;的位置List

主要

List<TextField> textFieldContainer = new ArrayList();

import javafx.application.Application;
import javafx.fxml.FXMLLoader;

    @Override
    public void start(Stage stage) throws Exception
    {
        Parent root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml"));

        Scene scene = new Scene(root);

        stage.setScene(scene);
        stage.show();
    }

    /**
     * @param args the command line arguments

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

        TextField typeText = new TextField();
        textFieldContainer.add(typeText);//Add your textField to the container when you create it

        VBox bankContainer = new VBox(bankLabel, bankText);

        tile.getChildren().addAll(typeContainer, bankContainer);

        TitledPane titledPane = new TitledPane("Параметры выпуска " + index, tile);

        return titledPane;
    }
}
