[Tex/LaTex] Modifying a template fancy chapter

fncychap

I am using roughly the following setup

\documentclass[11pt]{book}
\usepackage{hyperref}                   
\usepackage[bf]{caption} 
\usepackage{subcaption}
\usepackage{amssymb}
\usepackage[fleqn]{amsmath,mathtools}
\usepackage{fancyhdr}
\usepackage[Lenny]{fncychap}

\begin{document}
*some stuff*
\mainmatter
\input{Chapters/Chapter1}
etc.
\end{document}

I think the "Lenny" chapter style looks really nice. I would only like to change one minor detail: the title of the chapter is not printed boldfaced. For every chapter it is easy to change this: I simply write \chapter{{\bf TITLE}}. However, I would also like to have this for the Table of Contents and "Symbols" pages. How to do this?

Contrary to you, I find the Lenny chapter style one of the ugliest I've ever seen.

Add

\ChTitleVar{\Huge\bfseries}

to your preamble.

\documentclass[11pt]{book}
\usepackage[bf]{caption}
\usepackage{subcaption}
\usepackage{amssymb}
\usepackage[fleqn]{amsmath,mathtools}
\usepackage{fancyhdr}
\usepackage[Lenny]{fncychap}
\usepackage{hyperref}

\ChTitleVar{\Huge\bfseries}

\begin{document}
\mainmatter
\chapter{A nice title}
\end{document}

By the way, hyperref should be loaded last.

You may slightly improve the appearance by not using Helvetica and Times.

\documentclass[11pt]{book}
\usepackage{fix-cm}
\usepackage[bf]{caption}
\usepackage{subcaption}
\usepackage{amssymb}
\usepackage[fleqn]{amsmath,mathtools}
\usepackage{fancyhdr}
\usepackage[Lenny]{fncychap}
\usepackage{hyperref}

\ChTitleVar{\Huge\bfseries}
\ChNameVar{\large\bfseries}
\ChNumVar{\fontsize{60}{62}\bfseries}

\begin{document}
\mainmatter
\chapter{A nice title}
\end{document}

Instead of \bfseries in \ChNumVar you might want \fontseries{b}\selectfont.

However, it's still irremediably ugly.
