在 tikzuml 中为未对齐的类绘制直线

Question

我一直在尝试使用包中的所有选项tikz-uml来为两个未对齐的类获取一条直线

\usepackage{float}
\usepackage{tikz}
\usepackage{tikz-uml}
\usepackage{adjustbox}
\usetikzlibrary{positioning}
\usetikzlibrary{arrows.meta}


\begin{document}\errorcontextlines=9

\begin{figure}[H]
    \centering
        \begin{tikzpicture}

            \umlclass[]{ApplicationController}
            {
                
            }
            {
                
            }

            \umlclass[below right=2cm and -1cm of ApplicationController]{RelayHandler}{}
            {
                
            }

            \umluniassoc[]{ApplicationController}{RelayHandler}
            

        \end{tikzpicture}
\end{figure}

\end{document}

我需要的是

Answer 1

使用 calc 库，我在“应用程序控制器”框边缘(aux)的中心和“RelayHandler”节点的边缘放置一个辅助点。然后使用语法，我放置箭头。south eastnorth west|-

\documentclass[tikz,border=1mm]{standalone}

\usepackage{float}
\usepackage{tikz}
\usepackage{tikz-uml}
\usepackage{adjustbox}
\usetikzlibrary{positioning}
\usetikzlibrary{arrows.meta,calc}
\tikzset{> = {Straight Barb[length=4pt,width=3.4pt]}}

%            \umluniassoc[]{ApplicationController}{RelayHandler}
            \coordinate (aux) at ($(ApplicationController.south east)!.5!(RelayHandler.north west)$);
            \draw[->](ApplicationController.south-|aux)--(aux|-RelayHandler.north);
