Question

基本上列出要累加的标签列表。当它们到达底部时，它们越界（也必须在TextField的后面），并且无法滚动它。如何使他们表现正常？标签被添加到ScrollPane内的VBox中

标签添加方法在另一个线程中（由于游戏机制的原因）

@FXML
    public void text(String text1) {
        Platform.runLater(new Runnable() {
            @Override
            public void run() {
                Label label = new Label(text1);
                box.getChildren().add(label);

            }
        });
        listener = false;
        // scroll to bottom

    }

Answer 1

从fxml fitToHeight="true"中删除此代码，它很不错。

Answer 2

显然我的GameEngine类看不到正确的节点，因此我将它们从控制器传递到引擎方法中。现在像魅力一样工作

无法使用ScrollPane滚动充满标签的VBox
