java - 如何使按钮出现在 TitledPane JavaFX 的右侧

Question

我已经设法使用 setGraphic 在 TitledPane 中放置一个按钮，但我希​​望它位于右侧；这是代码:

@Override
public void start(Stage primaryStage) {

    Accordion acordion = new Accordion();

    TitledPane tp1 = new TitledPane();

    Button b1 = new Button();

    b1.setText("X");

    tp1.setGraphic(b1);

    acordion.getPanes().addAll(tp1);

    Scene scene = new Scene(acordion, 300, 250);

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

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

The Button should be located on the right but I do not know how to do it

Answer 1

将 TitledPane 的 alignment 属性设置为 CENTER_RIGHT:

tp1.setAlignment(Pos.CENTER_RIGHT);
