Java 复选框节点渲染器和编辑器

我已经渲染了一棵有两种节点的树

叶节点

父节点

一-表示父节点。 二，三-表示叶节点

我需要写两个独立的编辑吗？ 一个用于父节点，一个用于叶节点

我能做到这一点吗

如何编写新的渲染器来渲染两种不同类型的节点？以及相应的编辑器？

只需创建两个独立的

TreeCellEditor

实现，并将它们与类合并在一起，如下所示：

public class TreeCellEditorDelegate extends DefaultTreeCellEditor {

    private final TreeCellEditor    editorParent;
    private final TreeCellEditor    editorLeaf;

    public TreeCellEditorDelegate(
            final JTree tree,
            final DefaultTreeCellRenderer renderer,
            final TreeCellEditor editorParent,
            final TreeCellEditor editorLeaf) {
        super(tree, renderer);
        this.editorParent = editorParent;
        this.editorLeaf = editorLeaf;
    }

    @Override
    public Component getTreeCellEditorComponent(
            final JTree tree,
            final Object value,
            final boolean isSelected,
            final boolean expanded,
            final boolean leaf,
            final int row) {
        if (leaf)
            return editorLeaf.getTreeCellEditorComponent(tree, value, isSelected, expanded, true, row);
        else
            return editorParent.getTreeCellEditorComponent(tree, value, isSelected, expanded, false, row);
    }
}
