java - 内联显示 javaFX gui 元素

Question

我在寻找如何在 JavaFX gui 中的同一行中显示两个元素的答案时遇到了一些麻烦。我想在同一行中以 50% 的宽度显示单选按钮，并使用两个文本字段进行相同的操作。

我添加了部分代码:

primaryStage.setTitle("Acoustic Insulation");

        ToggleGroup signalGroup = new ToggleGroup();
        final RadioButton radioSweep = new RadioButton("Sweep");
        radioSweep.setToggleGroup(signalGroup);
        radioSweep.setStyle(" -fx-display:inline-block ");

        final RadioButton radioSin = new RadioButton("Sin");
        radioSin.setToggleGroup(signalGroup);
        radioSin.setStyle(" -fx-display:inline-block ");

        Label frequencyLabel = new Label("Frequency:");
        final TextField frequencyText = new TextField();

        Label timeLabel = new Label("Set time [s]:");
        final TextField timeText = new TextField();

        Button startBtn = new Button();
        startBtn.setText("START");

和实际 View :

Answer 1

试试这个

    GridPane root = new GridPane();
    root.setAlignment(Pos.CENTER);
    root.setHgap(12);

    HBox box = new HBox();
    box.getChildren().addAll(radioSweep, radioSin);
    box.setSpacing(50);
    box.setPrefWidth(200);

    HBox box1 = new HBox();
    box1.getChildren().addAll(frequencyText, timeText);
    box1.setSpacing(12);
    box1.setPrefWidth(200);

    root.add(box, 0, 0);
    root.add(box1, 1, 0);

    Scene scene = new Scene(root, 500, 500);
    primaryStage.setScene(scene);
    primaryStage.show();
