tikz：使用不带单位和带单位的指标时的定位

Question

我在使用 beamer 主题时遇到了一些困难，我想是因为我使用了带和不带单位的位置的 tikz。

我想要一个使用页码的列表(0,\pgnbr)，我将其定义为y=1.5cm打开\begin{tikzpicture}[y=1.5cm]，但我无法使用单位度量来移动它。即(0,\pgnbr+2cm)似乎扭曲了一切。

看看发生了什么可能更容易。我的模板中的问题很明显：

1. 我想让标题栏方块扩大
2. 我希望侧边栏向下移动以免与标题栏重叠
3. 侧边栏应该“拉伸”（参见我对此行的评论 \begin{tikzpicture}[y=1.5cm]）

代码：

\usepackage{tikz}

%% SIDEBAR

\def\swidth{1.2cm}  % sidebar size
\def\sheight{\paperheigth / \inserttotalframenumber}
\def\theight{1.0cm}  % frametitle size

\setbeamersize{sidebar width right=\swidth}
\setbeamerfont{sidebar right}{size=\normalsize}
\setbeamertemplate{sidebar right}{%
\begin{tikzpicture}[y=1.5cm]   % FIXME: y=\sheight not working !
    \foreach \i in {2,...,\inserttotalframenumber} {
        \def\pgnbr{\inserttotalframenumber - \i-1}
        \ifnum\i=\insertframenumber
            \filldraw[very thick] (0,\pgnbr) rectangle (\swidth,\pgnbr+1);
            \node[white,anchor=mid,font=\bfseries] at (\swidth/2,\pgnbr+0.5) {\number\numexpr\i-1};
        \else
            \draw[very thick] (0,\pgnbr) rectangle (\swidth-0.07cm,\pgnbr+1);
            \node[anchor=mid,font=\bfseries] at (\swidth/2,\pgnbr+0.5) {\number\numexpr\i-1};
        \fi
    }
\end{tikzpicture}
}

%% TITLE

\setbeamersize{frametitle height=\theight}
\setbeamercolor{frametitle}{fg=black}
\setbeamerfont{frametitle}{size=\Large\bfseries}
\setbeamertemplate{frametitle}{%
\begin{tikzpicture}
\draw[very thick] (0,0) rectangle (\paperwidth,\theight);
\node[anchor=mid] at (\paperwidth/2,\theight/2) {\insertframetitle};
\end{tikzpicture}
}

%%

\begin{document}

\setbeamertemplate{sidebar right}{}
