javafx-2 - 在 JavaFX/FXML 中创建灵活的 3 框布局的最佳方法

Question

我想在 JavaFX/FXML 中创建一个灵活的 3 框布局。一张图片最能描述它，就像下面这样:



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。

所以代码如下(简化代码)。

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

这里最好的方法是什么？两个嵌套 SplitPane ?

Answer 1

What could be the best approach here? Two nested SplitPanes?

是的，我会这样做。



要获得上面的模拟布局，请尝试在 SceneBuilder 1.1 early access 中打开以下 fxml .

<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
