Javafx 2 在JavaFX/FXML中创建灵活的3框布局的最佳方法

我想在JavaFX/FXML中创建一个灵活的3盒布局。一张图片最好地描述了这一点，如下所示：

如您所见，主要部分应由三个可调整大小的框组成。所有这些盒子都应该有一个首选的尺寸

因此，代码如下所示（简化代码）

这里最好的方法是什么？两个嵌套的

SplitPane

这里最好的方法是什么？两个嵌套的拆分窗格

是的，我会的

要获得上面的模拟布局，请尝试在中打开以下fxml

<BorderPane>
  <top>
    <VBox>
      <!-- menubar stuff -->
    </VBox>
  </top>
  <center>
    <!-- ACTUAL CONTENT HERE -->
  </center>
  <bottom>
    <!-- toolbar stuff -->
  </bottom>
</BorderPane>
