JavaFX - 如何在锚点窗格中添加容器

添加fx:id到AnchorPane您想要操作的:

<AnchorPane fx:id="leftAnchorPane" min min
    pref pref />

作为@FXML成员字段在控制器中获取它:

public class FXMLDocumentController
{
    @FXML private AnchorPane leftAnchorPane;
    ...
}

并在所需的位置操纵它(initialize()此处显示,几乎可以在任何其他地方):

public void initialize() {
    VBox vbox = new VBox();
    ...
    AnchorPane.setTopAnchor(vbox, 10.0); // obviously provide your own constraints
    leftAnchorPane.getChildren().add(vbox);
}
