FXFでBorderPaneにJavaFX FlowPaneを挿入

Question

私はJavaFXの初心者です。私はFXMLを使って基本レイアウトを作成しようとしています。私はBorderPaneで始まり、中央では2つのセクションを作成したいし、HBoxまたはフロー/タイルペインのいずれかを使用しようとしていました。

私はそれが可能だ知っている：http://docs.oracle.com/javafx/2/layout/builtin_layouts.htm

しかし、私はFXMLでそれを行う方法がわかりません。私は本当にそれに関する良い情報を見つけるのに苦労している。ここで私はHBoxのにしようとしたものです：

<BorderPane id="main" prefHeight="500" prefWidth="500" xmlns:fx="http://javafx.com/fxml/1" fx:controller="inventorymanagementsystem.FXMLDocumentController">  
    <top> 
     <Label text="Label 1" /> 
    </top> 
    <center> 
     <HBox alignment="LEFT"> 
      <children> 
       <Label text="Label 2" /> 
      </children> 
     </HBox> 
    </center> 
</BorderPane> 

しかし、私はこれらのエラーを取得：

任意の提案をいただければ幸いです。

Answer 1

LEFTは、のうち有効な値ではありません.HBoxのalignment propertyは、Posを予期しています。必要に応じて"CENTER_LEFT","TOP_LEFT"、または"BOTTOM_LEFT"を使用してください。
