文本内使用定义字体进行换行

Question

我不确定这是否是正确的描述。我有应用于整个文档的默认字体。并且我有一个在命令 \teacher{} 中调用的字体。

\documentclass[a4paper,11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{pgf,tikz}

\begin{document}


\newcommand{\cur}[1]{{\fontfamily{qzc}\selectfont #1}}

\begin{center}
    {\Huge \color{blue!90!green!50}{\textbf{Title}}}
\end{center}
 
\bigskip 

\newcommand{\teacher}[1]{
\tikz[baseline]{
\draw (0,0) node[left=0.3cm,align=center,fill=violet!20,draw=violet,rounded corners,line width=2pt,inner sep=5pt] {\cur{#1}}
 }
}

\newcommand{\lteacher}[1]{
\tikz[baseline]{
\draw (0,0) node[left=0.3cm,align=center,fill=violet!20,draw=violet,rounded corners,line width=2pt,inner sep=5pt] {#1} 
 }
}


Normal text.\\

\bigskip

%test%
\teacher{This is line 1.\\ This is line 2.}\\

\bigskip

\lteacher{\cur{This is line 1.}\\ \cur{This is line 2.}}





\end{document}

我想要的是能够在第一个命令 \teacher{} 而不是 \lteacher 内进行换行。

这是我使用 MWE 获得的结果（第一个命令显然产生了错误）：

Answer 1

在节点选项中使用font=\fontfamily{qzc}\selectfont。它将字体应用于多行节点的所有行。

\documentclass[a4paper,11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{pgf,tikz}

\begin{document}        
    
    \newcommand{\cur}[1]{{\fontfamily{qzc}\selectfont #1}}      
    
    \newcommand{\teacher}[1]{%
        \tikz[baseline]{%
            \draw (0,0) node[left=0.3cm,align=center,fill=violet!20,draw=violet,rounded corners,line width=2pt,
            inner sep=5pt,
            font=\fontfamily{qzc}\selectfont %<<<<<<<<<<<<<<<<<<
            ] {#1}
        }
    }
    
    \newcommand{\lteacher}[1]{%
        \tikz[baseline]{%
            \draw (0,0) node[left=0.3cm,align=center,fill=violet!20,draw=violet,rounded corners,line width=2pt,inner sep=5pt] {#1} 
        }
    }
    
    
    Normal text.\\
    
    \bigskip
    
    %test%
    \teacher{This is line 1.\\ This is line 2.}\\
    
    \bigskip
    
    \lteacher{\cur{This is line 3.}\\ \cur{This is line 4.}}
    
    
\end{document}
