JavaFX - How can i add a container in an anchor pane
提问by ciprianr
I have a simple project that has a fxml with a splitter.
我有一个简单的项目，它有一个带拆分器的 fxml。
So the fxml is this:
所以 fxml 是这样的：
<AnchorPane id="AnchorPane" prefHeight="200" prefWidth="320" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8" fx:controller="accordionproject.FXMLDocumentController">
<children>
<SplitPane fx:id="splitPane" dividerPositions="0.29797979797979796" focusTraversable="true" layoutX="60.0" layoutY="14.0" prefHeight="200.0" prefWidth="320.0" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0" xmlns:fx="http://javafx.com/fxml">
<items>
<AnchorPane minHeight="0.0" minWidth="0.0" prefHeight="160.0" prefWidth="100.0" />
<AnchorPane minHeight="0.0" minWidth="0.0" prefHeight="160.0" prefWidth="100.0" />
</items>
</SplitPane>
</children>
</AnchorPane>
What i would want is to insert a vbox in the left anchor pane from the splitter using only java code.
我想要的是仅使用 java 代码在拆分器的左锚窗格中插入一个 vbox。
Can this be done?
这能做到吗？
I am new to fxml so any help would be apreciated.
我是 fxml 的新手，所以任何帮助都会受到赞赏。
Thank you in advance.
先感谢您。

Add an fx:idto the AnchorPaneyou want to manipulate:
添加一个fx:id到AnchorPane你想要操作的：
<AnchorPane fx:id="leftAnchorPane" minHeight="0.0" minWidth="0.0"
prefHeight="160.0" prefWidth="100.0" />
Get it in your controller as a @FXMLmember field:
在您的控制器中将其作为@FXML成员字段获取：
public class FXMLDocumentController
{
@FXML private AnchorPane leftAnchorPane;
...
}
And manipulate it in the desired place (initialize()shown here, can be -almost- anywhere else):
并在所需的位置操作它（initialize()如图所示，几乎可以在其他任何地方）：
public void initialize() {
VBox vbox = new VBox();
...
AnchorPane.setTopAnchor(vbox, 10.0); // obviously provide your own constraints
leftAnchorPane.getChildren().add(vbox);
}

You should try the JavaFX Scene Builder. It makes editing your fxml much easier as it is all done graphically.
您应该尝试使用 JavaFX Scene Builder。它使编辑 fxml 变得更加容易，因为它都是以图形方式完成的。
