        </columns> 
       </TableView> 
      </children> 
     </VBox> 

    </children> 
</AnchorPane>

我想要的形象出現在右上角，但它不是在那裏定位我試圖用「layoutX和layoutY」來改變X和Y座標，但這似乎並不奏效。

是否有任何理由爲什麼您在節點層次結構中的該點添加了'ImageView'，而不是作爲根'AnchorPane'的子節點？此外，在將來請通過確保發佈證明您的問題的[最簡單示例]（http://stackoverflow.com/help/mcve）來幫助那些試圖幫助您的人。你已經添加了很多'節點'，有點難以找到你所要求的'Node'... – fabian

爲什麼不把它添加到你的'GridPane'的最後一列，rowSpan = 2，而不是添加它到'HBox'？ – DVarga

@Fabian下次我會照顧最小的例子，我嘗試了你的建議，但它是來到左上角，我無法將它移到右上角。 – user3649361

不同的Pane s有不同的方式來選擇孩子的位置。

在AnchorPane的情況下，可以使用錨定屬性完成對頂部右角的對齊。這些屬性控制父代AnchorPane的子節點到窗格邊界的距離。

下面的例子在AnchorPane的右上角放置一個Rectangle：

<AnchorPane id="AnchorPane" prefHeight="400.0" prefWidth="600.0" xmlns:fx="http://javafx.com/fxml/1"> 
    <children> 
     <Rectangle width="50" height="50" AnchorPane.topAnchor="0" AnchorPane.rightAnchor="0" /> 
    </children> 
</AnchorPane>

你可以放置ImageView在你FXML右上角這種方式太。
