%
% Jeopardy like game -- redesigned the \verb|jj_game.cls| by D. P.
% Story.  The package requires to load \verb|exerquiz| and
% \verb|dljslib| packages from AcroTeX bundle. The current only
% supported way to produce pdf file is \verb|pdftex|. The main
% properties include
% \begin{itemize}
% \item In contrast to \verb|jj_game.cls|, the \verb|oQuestion|
%   environment is used to allow fill-in questions.
% \item The \verb|proofing| option is introduced. Use this option to
%   typeset your answers into the document. To check the answers for
%   \verb|\RespBoxMath| and |\RespBoxTxt| commands remember to use
%   transparent background for these text fields or use the browser
%   which does not show these fields, like \verb|xpdf|.
% \item Option |twoplayers| builds game for two players.
% \item Option |bgpicture| is used to place the picture below the
%   buttons (|graphicx| package is used). The name of the picture is
%   stored in the |\JeopardyPictureFile| command. Default value is
%   |picture.jpg|.  You can change it by using command like
%   |\def\JeopardyPictureFile{blabla.jpg}|. If you use this option,
%   you may also consider the (rather tricky) option |finetune|. This
%   option is described with the corresponding code at the end of this
%   file. The |bgpicture| option is automaticaly turned on when
%   |picture| option is active.
% \item The option |picture| is introduced for another version of the
%   game. The user gets no score but uncovers parts of a picture
%   hidden by buttons and (after wrong answer) non-transparent fields.
%   It can be used in the class and students can guess what is on the
%   picture. The option adds the "Solution" button below the
%   gameboard.  If the user clicks this button, all buttons from not
%   yet answered questions and fields from wrong answered questions
%   are hidden and the picture is fully visible. After the second
%   click on this button, a |\ChampionMsg| is shown. This can be used
%   for example to store the name of a person on the picture. 
% \item The user is not allowed to browse pages of the game without
%   clicking in gameboard. We use the (not portable)
%   \verb|\pdfpageattr| command to achieve this behavior. This can be
%   turned off by \verb|allowpeeking| option.
% \item The \verb|evalonblur| option may be used. This concerns
%   filling forms for |\RespBoxTxt| and |\RespBoxMath| questions and
%   the following problem with switching keyboard layout: When filling
%   the text field, if user switches the keyboard
%   layout\footnote{necessary, for example, to write powers on Czech
%     keyboard} using keyboard shortcut on Linux, the (not yet
%   finished and hence incorrect) answer is evaluated and marked as
%   wrong. Known workarounds:
%   \begin{itemize}
%   \item The user should erase the contents of the field completely,
%     switch the keyboard, click into the field and type his/her
%     answer.
%   \item The user should change keyboard using mouse and Gnome applet.
%   \item The author can compile the file with \verb|evalonblur|
%     option. The answer is evaluated after \verb|shift+click|-ing
%     outside the field.
%   \end{itemize}
% \end{itemize}
% This package has been tested on Texlive2005+Linux (pdfeTeXk, Version
% 3.141592-1.30.4-2.2 (Web2C 7.5.5)), with \verb|exerquiz| 2006/18/06
% v6.05e.
%
% \section{Usage}
%
% To instal the style run |latex jeopardy.ins| from the directory with
% |jeopardy.dtx|. You get files |jeopardy.sty| and |jeopardy.cfg|.
% Copy both files where \LaTeX{} finds them and include your
% customizations into |jeopardy.cfg|.
%
% For sample file look at the files \verb|game*.tex|. The number of
% questions and categories is written into \verb|aux| file and stored
% in macros \verb|\NumberOfQuestions| and \verb|\NumberOfCategories|.
% From this reason, the file has to be two times \verb|pdflatex|-ed to
% build the game.  The |aux| file contains also definitions for the
% category names. These names are not used when |picture| option is
% active. 
%
% \DescribeMacro{\MakeGameBoard} Macro |\MakeGameBoard| typesets the
% game board. This should be at the begin of the file and followed by
% \verb|category| environments. The dimensions of cells are
% \verb|\CellWidth| and \verb|\CellHeight|. The user can set these
% dimensions after \verb|\begin{document}| or with the |\SetGameWidth|
%   and |\SetGameHeight| commands. Write e.g. |\SetGameHeight{10cm}|.
%   The fields are created via \verb|\pushButton| and
%   \verb|\textField| commands and the user may change the default
%   behavior using command available in the package \verb|eforms.sty|.
%   The colors for wrong and right messages are set in \verb|exerquiz|
%   package and stored in \verb|\correctColor| and \verb|\wrongColor|
%   macros. The tokens registers |\GrandPoohbahtoks|, |\Celltoks| and
%   |\Scoretoks| are used to build the GrandPoohbah field (see below),
%   cell fields and score field. You can set it by e.g.
%   |\GrandPoohbahtoks{\Q{0}\textColor{1 0 0 rg}}|. All these
%   registers are empty by default. The exception is if the |picture|
%   option is used, the |\Celltoks| is set to |\BG{0 0 0}|. If you
%   change it, remember to use non-transparent background for cells!
%
%   \DescribeMacro{\AfterGameBoard} Macro |\AfterGameBoard| is
%   execuetd between gameboard and score field.
%
%   \DescribeMacro{\everyCategoryHead} Tokens register
%   |\everyCategoryHead| is used at the begin of every category head.
%   You can set it by something like
%   |\everyCategoryHead{\textrm\footnotesize}|
%
%   \DescribeMacro{\JeopardyTitle} The |\JeopardyTitle| macro contains
%   the title of the game. The title is the hyperlink anchor used to
%   return from questions to the gameboard. You can set it by e.g.
%   |\def\JeopardyTitle{The title of the game}|.
%
%   \DescribeEnv{category} The |category| environment has one
%   parameter -- the name of the category. It encloses \verb|question|
%   environments. The category name is not used if the |picture|
%   option is active. In this case the name is replaced by the capital
%   letter A, B, C, \dots. In this case you (or your students) can
%   refer to the fields like on chessboard.
%
% \DescribeEnv{question} The |question| environment contains a
% question and answers for multiple choice questions. The answers are
% introduced by \verb|\Ans0| (wrong answers) or \verb|\Ans1| (correct
% answers). The environment includes an \verb|oQuestion| environment
% and hence it may contain \verb|\RespBoxMath| or |\RespBoxTxt|
% command.
%
% \DescribeMacro{\Goal} If the user finishes the game with at least
% \verb|\Goal| points, a hidden banner (GrandPoohbah field) with
% message stored in \verb|\ChampionMsg| command is shown. The default
% initial value
% \verb|45*(1+numQuestions)*numQuestions*numCategories*\JeopardyScaleFactor| 
% means 90 percent of the maximal point score.  The banner has height
% \verb|\GrandPoohbahHeight|. This macro is not used if the option
% |picture| is active. In this case the |\ChampionMsg| should contain
% the name of the picture (for example the name of the person on
% photograph) and it can be shown by doubleclicking "Solution"
% button at the bottom.
%
% \DescribeMacro{\SetGameWidth} Macro |\SetGameWidth| sets the
% |\GameWidth| register with the width of the game desk. It evaluates
% the width of cells as quotient of the parameter of the macro and the
% number of categories. Macro |\SetGameHeight| works in a similar way
% if the option |picture| is not active. If the option |picture| is
% active, the height of the game is evaluated from the dimensions of
% the picture. The width of the picture is scaled into |\GameWidth| and
% the height is established from the height of the scaled picture.

% \verb|dljslib| packages are loaded.
