森林里的儿童错位

Question

问题

我正在尝试使用forest包绘制树形图。我有多行子元素（包括命令\texttt）和一行子元素（包含普通文本）。这导致子元素之间错位，如下图所示。

我希望所有子元素都与顶部对齐。我该如何实现？

尝试的解决方案

我尝试使用一些for tree受启发的附加选项这个答案。在此尝试中，我需要强制长树元素的换行符 ( \\)，因为这不会自动发生。错位减少了，但仍然存在。

Answer 1

像这样？

您只需要添加（在您的简单示例中） anchor=north节点样式：

\documentclass[10pt]{article}
\usepackage[edges]{forest}

% Document
\begin{document}
    \begin{figure}[hbt!]
        \centering
        \begin{forest}
    for tree={              % style of tree nodes
      draw, semithick, rounded corners,
      align = center,
      inner sep = 2mm,
      anchor=north,
                            % styles of tree
      forked edge,             
%      tier/.option=level,  % if you have more levels of children
        l sep = 6mm,    
     fork sep = 3mm,     
                }
[\texttt{Parent}\\   object
    [\texttt{AStandardChild}\\ object]
    [\texttt{VeryVeryVeryLongChild}\\ object]
    [\textrm{Other}]
]
        \end{forest}
    \end{figure}
\end{document}
