BorderPane - JavaFX Scene Builder - 滚动条向下按钮不可见

BorderPanes - JavaFX Scene Builder - Scrollbar down button not visibel

我对 BorderPanes (EBMTableView) - JavaFX Scene Builder 的下滚动条按钮的位置/可见性有一个小问题

我希望在最小化 window 时底部滚动条按钮始终可见。

非常感谢

请检查GUI代码和imgs。

问题已解决,只需像这样更改第一个 BorderPane 参数 ->

<BorderPane maxHeight="0" maxWidth="0"
minHeight="0" minWidth="0" prefHeight="0"
prefWidth="1230.0" xmlns="http://javafx.com/javafx/8.0.111"
