% \title{Menu.sty: Typesetting menus}
% \author{Knut Lickert}
% \maketitle
%
%\begin{abstract}
% Menu.sty define a command |\menu{Programm!!Menu1!Command}| and
% expand it to something like \menu{Programm!!Menu1!Command}. You
% can use it for documentations of programs.
%\end{abstract}
%
% \section{Where to use the style}
% If you write a documentation of a program you have to define
% things like "Push button \keystroke{F1} or go to the Menu to
% \menu{Help!Help} and you get help". This style help you to write
% the menu entry.
%
% \subsection{Other packages}
% I have not found a package to typeset menus (that's why this style
% was written). If you find one, please contact me
% (knut@lickert.net).
%
% \begin{description}
%    \item[keystroke]
%         A \LaTeX\ package which provides macros for the graphical
%         representation of the keys on a computer keyboard.\par
%           Example: \Ctrl, \Shift \AltGr
% \end{description}
%
%
% \section{How to use the style}
% \subsection{Inline-Menu}
%
% \DescribeMacro{\menu}
% |\menu| has one parameter. The macro is used to typeset a path in a
% menu. Like |\index| different levels are separated with a "!"
% inside the parameter. Instead a "!" you can use two "!!" and so you
% can define bigger steps in the menu. I use programs, where a menu
% is starting another menu (e.g.\ in a popup). So instead of saying
% "Goto \menu{Menu1!Entry1!Menu2} and then from
% \menu{Menu2!Menu3!Entry3}" I write "Goto
% \menu{Menu1!Entry1!Menu2!!Menu3!Entry3}.
%
% Example:
% \verb|\menu{File!Save!!Filename}|: \menu{File!Save!!Filename}
%
% This is only to show one path in a menu.
% This command may not be used to show a complete menu.
% I recommand to make a snapshot of your programm and include the picture
% via \verb|includegraphics| (Package graphicx)
%
%
% \subsection{Menu-Figure}
% \fixme{Description}
%\DescribeEnv{menufolder}
%Number of parameter: 2
%
%\DescribeMacro{\menuitem}
%Number of parameter: 2
%
%\DescribeMacro{\menuitemactive}
%Number of parameter: 2
%
%\DescribeMacro{\menuseparator}
% Add a separator line. An optional length can be defined.
%
% Example:
%\begin{verbatim}
%\settowidth{\menuitemlength}{Close and d\underline on't save}
%\begin{menufolder}{\underline Menu}%
%    \menuitem{Close and d\underline on't save}
%    \menuitem{Close and sa\underline ve}
%    \menuitemactive{I\underline tem}
%\end{menufolder}
%}
%\end{verbatim}

%\settowidth{\menuitemlength}{Close and d\underline on't save}
%\begin{menufolder}{\underline Menu}%
%    \menuitem{Close and d\underline on't save}
%    \menuitem{Close and sa\underline ve}
%    \menuitemactive{I\underline tem}
%\end{menufolder}
%
%\subsubsection{Options}
%There are different options to modify the look of menus.
%
%\begin{description}
%    \item[hand] The hand point to the active menu item.
%       Requires bbding.
%    \item[framed] The menu entries are framed
%    \item[grey] framed and background values.\fixme{change
%    option name}
%\end{description}
%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% \section{Changing the look}
% \DescribeMacro{\menutext}
% A step of a menu is written with this macro, default is
% |\texttt|. You can change it with |\renewcommand|, e.g.\
% |\renewcommand{\menutext}[1]{\emph{#1}|
%
% \subsection{Inline-Menus}
% \DescribeMacro{\menumathsymbols}
% If you want to replace the symbols, you can use |\menusymbols|.
% Parameter one is the flag for "!", Parameter for "!!"
% (Default is \(\rightarrow\) and \(\Rightarrow\)).
%
% \DescribeMacro{\menusymbols}
% Like |\menumathsymbols| with two differences:
% \begin{itemize}
%   \item There is no math-environment (if you need it, you can
%         guarantee it with |\ensuremath|)
%   \item There are two optional parameters, defining a start and
%         end command of a menu.
% \end{itemize}
% This command gives you a flexible possibility to change the look
% of menus.
%
% \begin{description}
%   \item[$\backslash$menusymbols] Define a style with the parameters:
%   \item[{[Start]}] How should a menu start.\par
%         A |\par| is not allowed, but you can use a |\\|. If a paragraph
%         ends before the |\menu|, you must use |~\\| instead.
%   \item[\{\}] The look/actions for a "!" in a menu.
%   \item[\{\}] The look/actions for a "!!" in a menu.
%   \item[{[End]}] How should a menu end.
% \end{description}
%
% \subsubsection{Examples}
% \newcommand{\example}[1]{\texttt{$\backslash$menu\{#1\}} &amp; \menu{#1}\\}
%
% \paragraph{Predefined look}~\par
%
% \begin{tabular}{ll}
% Coding    &amp; Result\\\hline
% \example{Menu!Menu}
% \example{Menu!!Menu}
% \example{Menu!!Next Menu!Entry}
% \end{tabular}
%
% \paragraph{Changed symbols}
%
% After |\menumathsymbols{&gt;}{\gg}| you get\par
% \menumathsymbols{&gt;}{\gg}
% \begin{tabular}{ll}
% Coding    &amp; Result\\\hline
% \example{Menu!Menu}
% \example{Menu!!Menu}
% \example{Menu!!Next Menu!Entry}
% \end{tabular}
%
% Attention: If you want to change it local, you must define a
% block.
%
% \paragraph{Define your own styles}
%
% You can define your own "styles", |\menu{Menu!!Next Menu!Entry}|
% makes an entry like:
%
% \begin{minipage}[t]{0.5\textwidth}
%\begin{verbatim}
%\newlength{\menusep}
%\menusymbols[
%   \setlength{\menusep}{0em}~\\
% ]{
%   \\
%   \addtolength{\menusep}{1em}
%   \hspace*{\menusep}
% }{
%   $\wr$\\
%   \addtolength{\menusep}{2em}
%   \hspace*{\menusep}
% }[
% \ensuremath{\Leftarrow}
% ]
%\end{verbatim}
% \end{minipage}
% \begin{minipage}[t]{0.4\textwidth}
% Example for a new style
% \menusymbols[\setlength{\menusep}{0em}~\\]{
%    \\
%    \addtolength{\menusep}{1em}
%    \hspace*{\menusep}
%  }{
%    $\wr$\\
%    \addtolength{\menusep}{2em}
%    \hspace*{\menusep}
%  }[
%  \ensuremath{\Leftarrow}
%  ]
% \menu{Menu!!Next Menu!Entry}
% \end{minipage}
%
% \subsection{Layout of Menu-figures}
%
% The macros can be replaced. See the implementation for examples.
%
% \fixme{describe length}
%
%\DescribeMacro{\menufolderentry}
% Defines the look of the entry of a menu.
% Parameters are length (optional) and text.
%
%\DescribeMacro{\menuitem}
% Defines the look of one item in the menu.
% Parameters are length (optional) and text.
%
%\DescribeMacro{\menuitemactive}
% Defines the look of an active item in the menu.
% Parameters are length (optional) and text.
%
%\DescribeMacro{\menuitemactivesymbol}
% This symbol is used to show to the active item.

%
% \section{Ideas for the future}
% \begin{itemize}
%   \item Create Index entries for menus (optional)\par
%         If I do it, it would be an additional index (style multind).
%         I think this would be wrong in the normal index.
%   \item An optional parameter: |\menu[Programm]{Menu!...}|\par
%         Does anybody need it? At the moment I think there is no need.
%         When there is the possibility of index entries, then it could be sensefull
%         (Index is sorted by Programm, Menu1, Menu2\ldots).
%   \item A command |\popup| or |\rightmouse| to define a click on the
%         right mouse button. |\click[Feld]{menu!entry}|.
%         This function could be a feature of the package keystroke.
%         %^^A use mousesymbols.tex
% \end{itemize}
%
% Any comments? Up to now I don't need this features, so I will not
% implement them. If you need it, or think you have a better idea,
% send me a mail to knut@lickert.net.
%
% If you built your own "fancy" style, or have another idea to use
% "!!" and "!", please send me your idea.
