java - MigLayout - 使单元格随着窗口的增长而增长

Question

我想要发生的是东部和南部的 jetty 移动到窗口的边缘，中间的两个单元填充所有其他空间。相反， jetty 是静态的，拉伸(stretch)窗口只会产生空白空间。

    setLayout(new MigLayout(""));
    treeScrollPane = new JScrollPane();
    add(treeScrollPane, "growy, growx");

    displayedTree = tree;
    treeScrollPane.setViewportView(displayedTree);

    JScrollPane scrollPane = new JScrollPane();
    add(scrollPane, "growy");

    parentsTable = new JTable();
    parentsTable.setFillsViewportHeight(true);





    scrollPane.setViewportView(parentsTable);
    parentsTable.setModel(new DefaultTableModel(


        new Object[][] {
        },
        new String[] {
            "Parent"
        }   
    ) 

    {
        public boolean isCellEditable(int row, int column) {
            return false;
        }

    });
        JPanel easternDock = new JPanel(new MigLayout("insets 0", "", "push[]")); 

    JPanel bottomPanel = new JPanel(new MigLayout());
... add a bunch of stuff to bottomPanel...
    easternDock.add(bottomPanel);
    Box southernDock = Box.createHorizontalBox();
... add a bunch of stuff to southernDock ...
... Do menu stuff ...
    this.add(southernDock, "dock south");
    this.add(menuBar, "dock north");
    this.add(easternDock, "dock east");

Answer 1

我通过将两个 Pane 添加到 SplitScrollPane 中，然后将其添加到具有“推送、增长”约束的 mainPanel 来解决了这个问题。

JSplitPane splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT,
                treeScrollPane, scrollPane);
        splitPane.setOneTouchExpandable(true);
        splitPane.setDividerLocation(400);
        splitPane.setContinuousLayout(true);

add(splitPane, "push, grow");
