如何在HBox中的其他两个节点之间添加节点？

Question

Consider the following code:

HBox hbox = new HBox();
Button button1 = new Button("A");
Button button2 = new Button("B");
hbox.getChildren().addAll(button1, button2);

If I wanted to add a node between the two current nodes, is there a way to do it without removing all the nodes first then re-adding them?

Answer 1

因为getChildren()返回一个ObservableList ，你是否应该能够使用add(int index, E element)在你想要的索引中添加元素？
