使用SplitPanes构建BorderPane并最小化隐藏节点的区域

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.SplitPane;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;

BorderPane borderPane = new BorderPane();

Node leftNode = new Node();
Node rightNode = new Node();
Node centerNode = new Node();

SplitPane splitPane = new SplitPane();
splitPane.getItems().addAll(leftNode, rightNode);

splitPane.setDividerPositions(0.3); // 设置分割位置为30%
splitPane.setDividerPosition(0, 0.3); // 设置第一个分割条的位置为30%

borderPane.setCenter(splitPane);

borderPane.setTop(topNode);
borderPane.setBottom(bottomNode);

Scene scene = new Scene(borderPane, 800, 600);

Stage stage = new Stage();
stage.setScene(scene);
stage.show();
