java - JSplitPane + MiGLayout : how to enable proportional autoresizing

Question

后续问题 to my other one ;

如何启用按比例调整大小？我认为这行得通，但行不通:

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JSplitPane;
import net.miginfocom.swing.MigLayout;

public class SplitPaneQuestion {
    public static void main(String[] args) {
        JFrame frame = new JFrame("SplitPaneQuestion");
        JPanel panel = new JPanel();
        frame.setContentPane(panel);
        panel.setLayout(new MigLayout("","[]","[grow]"));
        JSplitPane splitpane = new JSplitPane(JSplitPane.VERTICAL_SPLIT);
        panel.add(splitpane, "push, grow");

        splitpane.setTopComponent(new JButton("top"));
        splitpane.setBottomComponent(new JButton("bottom"));
        splitpane.setDividerLocation(0.333);

        frame.pack();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);
    }
}

我希望在调整整个框架大小时顶部/底部按钮大小的比例保持不变。 (默认比例为 1:2)

我该怎么做？

Answer 1

splitPane.setResizeWeight(0.333);
