Beamer Singapore 删除导航栏中的部分名称

Question

我使用了 Beamer 的新加坡主题，并做了一些修改。我想编辑序言，这样部分名称就不会出现在导航栏中，并为进度指示器（圆圈）腾出空间。我的母语是西班牙语，我不得不使用谷歌翻译，所以请原谅任何语言连贯性的不足。

您可以使用\setbeamertemplate{section in head/foot}{}从标题中删除部分名称：

\documentclass{beamer}

\usetheme{Singapore}

%Para el pie de página estructurado
\makeatletter
   
% para los colores de los círculos del encabezado:
\useoutertheme{miniframes}

% Un indicador que nos dice cómo deben elaborarse los círculos
\newif\ifnavbeforecurrent

% Restablecer la bandera antes de cada barra de navegación
\pretocmd\insertnavigation{\navbeforecurrenttrue}{}{}

% Cambiar el código de dibujo del círculo para que cambie base en la señal
\defbeamertemplate*{mini frame in current subsection}{changing}[1][50]
{%
  \begin{pgfpicture}{0pt}{0pt}{0.1cm}{0.1cm}
    \pgfpathcircle{\pgfpoint{0.05cm}{0.05cm}}{0.05cm}
    \ifnavbeforecurrent
        \pgfusepath{fill,stroke}
    \else
        \pgfusepath{stroke}
    \fi
  \end{pgfpicture}%
}
\setbeamertemplate{mini frame in current subsection}[changing]

% Después de dibujar el círculo para el marco actual, cambiar la señal
\defbeamertemplate*{mini frame}{changing}
{%
  \begin{pgfpicture}{0pt}{0pt}{0.1cm}{0.1cm}
    \pgfpathcircle{\pgfpoint{0.05cm}{0.05cm}}{0.05cm}
    \pgfusepath{fill,stroke}
  \end{pgfpicture}%
  \global\navbeforecurrentfalse
}
\setbeamertemplate{mini frame}[changing]

\setbeamertemplate{section in head/foot}{}
