Editable JxTreeTable の実用的な例はありますか..いくつかの方法を試しました。しかし運が悪い...最初の列だけが編集可能です。

すべての列を編集可能にするにはどうすればよいですか?

申し訳ありませんが、みんな

これが私のsrcコードです：

        Root.add(node);
        for (int j = 0; j < i; j++) {
            node.add(new DefaultMutableTreeTableNode(j));
        }

@Override

    return "dsdsddds";
}

@Override

    return 2;
}


@Override
public Object getValueAt(Object arg0, int arg1) {
    if (arg1 == 1) {
        return new String("hi " + arg0.toString());
    }
    return arg0;
}
}

ありがとうございます....すべての列を編集したいです。ただし、このコードは最初の列でのみ機能します。

これは簡単な例で、簡単な手順です

  • AbstractMutableTreeTableNode を拡張して、カスタムの編集可能な TreeTableNode を実装する
  • それを DefaultTreeTableModel で使用する
  • モデルで JXTreeTable をインスタンス化する

コード内:

/**
 * A custom node implementation.
 */
public static class ArrayNode extends AbstractMutableTreeTableNode {

    public ArrayNode(Object[] data) {
        super(data);
    }

    @Override
    public Object getValueAt(int column) {
        return getUserObject()[column];
    }

    @Override
    public void setValueAt(Object aValue, int column) {
        getUserObject()[column] = aValue;
    }

    @Override
    public int getColumnCount() {
        return 2;
    }

    @Override
    public Object[] getUserObject() {
        return (Object[]) super.getUserObject();
    }

    @Override
    public boolean isEditable(int column) {
        return true;
    }

}

// usage
ArrayNode root = new ArrayNode(new Object[] {"root", ""});
for (int i = 0; i < 5; i++) {
    root.add(new ArrayNode(new Object[]{"child", "" + i}));
}
JXTreeTable table = new JXTreeTable(new DefaultTreeTableModel(root));
