Question

我不知道为什么，但滑块只向左移动甚至锁定新位置。它使用了Zested和JEditorPane的NestedJSplitPane教程的修改版本。我的猜测是，JEditorPane会导致问题......

public frameMenu(){
    JEditorPane htmlPane;
    JTree parkSelect;
    JTree triggerSelect;
    URL helpURL;

    DefaultMutableTreeNode left = new DefaultMutableTreeNode("Tree Left");
    DefaultMutableTreeNode triggerTree = new DefaultMutableTreeNode("Tree Down");
    //nNode.createNodes();

    int HORIZSPLIT = JSplitPane.HORIZONTAL_SPLIT;
    int VERTSPLIT = JSplitPane.VERTICAL_SPLIT;

    boolean continuousLayout = true;

    parkSelect = new JTree(left);
    parkSelect.getSelectionModel().setSelectionMode(TreeSelectionModel.SINGLE_TREE_SELECTION);

    htmlPane = new JEditorPane();
    htmlPane.setEditable(true);

    triggerSelect = new JTree(triggerTree);
    triggerSelect.getSelectionModel().setSelectionMode(TreeSelectionModel.SINGLE_TREE_SELECTION);

    JSplitPane splitPane1 = new JSplitPane(VERTSPLIT, continuousLayout, htmlPane, triggerSelect);
    splitPane1.setOneTouchExpandable(true);
    splitPane1.setDividerSize(2);
    splitPane1.setDividerLocation(0.5);

    JSplitPane splitPane2 = new JSplitPane(HORIZSPLIT, parkSelect, splitPane1);
    splitPane2.setOneTouchExpandable(true);
    splitPane2.setDividerLocation(0.4);
    splitPane2.setDividerSize(2);

    JFrame frame = new JFrame("Trigger Editor");
    frame.setSize(600, 400);
    frame.add(splitPane2);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.pack();
    frame.setVisible(true);
}

这更像是一个剪辑，但问题是一样的。我不确定，我可以在一个帖子中放多少代码。

上下分割可以毫无问题地滑动，但是左右分开会导致问题。

JSplitPane尊重组件的最小尺寸。

我的猜测是，JEditorPane会导致问题......

正确，JEditorPane的最小尺寸似乎等于其首选尺寸。

您需要覆盖getMinimumSize() JEditorPane方法，以便为您的要求返回更合理的值：

htmlPane = new JEditorPane()
{
    @Override
    public Dimension getMinimumSize()
    {
        Dimension d = super.getMinimumSize();
        d.width = 100;

        return d;
    }
};

JSplitPane只向一侧滑动
