SetAlignment method in JavaFX
提问by Naor Levi
1) When I run it, all the objects placed in the TOP_CENTER as you can see in the code I tried to place the button in the BOTTOM_RIGHT and it didn't work.
1）当我运行它时，所有对象都放置在 TOP_CENTER 中，正如您在代码中看到的那样，我试图将按钮放置在 BOTTOM_RIGHT 中，但它不起作用。
2) Can a Sceneinclude two layouts? (Two VBox-es for example).
2) 可以Scene包含两个布局吗？ （VBox例如两个-es）。
public void NewQuestion ()
{
sum++;
t=new Text("Question number: "+sum);
textfield=new TextField();
pane = new VBox();
Button NextQuestion = new Button ("Next Question");
NextQuestion.setOnAction(e-> NextQuestionButtonClicked(e));
pane.getChildren().addAll(t, textfield, NextQuestion);
pane.setAlignment(Pos.TOP_CENTER);
NextQuestion.setAlignment(Pos.BOTTOM_RIGHT);//<---
Scene mainscene = new Scene(pane,420, 530);
Qstage.setScene(mainscene);
}

Answering your second question first : each layout is a node so you can make a Hbox and then add 2 Vboxs to it and in a similar fashion have all combinations of it. since each button is also a node, you can add a Vbox and a button to an Hbox to position them horizontally with respect to each other
首先回答您的第二个问题：每个布局都是一个节点，因此您可以制作一个 Hbox，然后向其中添加 2 个 Vbox，并以类似的方式拥有它的所有组合。由于每个按钮也是一个节点，因此您可以将 Vbox 和按钮添加到 Hbox 以将它们相对于彼此水平放置
Now back to your first question:
Here is a list and an example with Pos.CENTER and Pos.CENTER_LEFT :
现在回到你的第一个问题：这是一个列表和一个 Pos.CENTER 和 Pos.CENTER_LEFT 的例子：

1) button.setAlignmentsets how the text and icons are places insidethe button (javadoc). To align the buttonwithin a paneyou should apply desired alignment to the paneitself. In you case:
1)button.setAlignment设置文本和图标在按钮内的放置方式( javadoc)。要button在 a 内对齐，pane您应该将所需的对齐应用于pane自身。在你的情况下：
pane.setAlignment(Pos.BOTTOM_RIGHT);
instead of
代替
pane.setAlignment(Pos.TOP_CENTER);
2) The Sceneshould have a single root. But the rootitself may be a VBoxor HBoxand you could put multiple boxes inside other box.
2)Scene应该有一个root. 但它root本身可能是一个VBox或HBox，你可以在另一个盒子里放多个盒子。
