+The graphicxbox Package
+Author: D. P. Story
+Dated: 2017-03-02
+
+This package provides JavaScript code snippets to create 'gray hints'. Gray 
+hints, as I term them, are text that appears initially in a text field that 
+gives a short hint as to what the contents of the text field should be; for 
+example, a text field might contain the hint 'First Name', or a date field 
+might read 'yyyy/mm/dd'. As soon as the field comes into focus, the hint 
+disappears. It reappears when the field is blurred and the user did not enter 
+any text into the field.
+
+Dependent packages: 
+    (1) eforms (2017/02/27) to use the field fields of eforms.
+    (2) insdljs (2017/03/02) a minimal requirement when using form fields defined
+        by hyperref when calculation fields are used.
+    (3) Hyperref form fields may be used without eforms or insdljs, but the gray
+        hints for calculation fields will not appear. 
+
+Package works for dvips/Distiller, pdflatex, lualatex, and xelatex.
+     
+Enjoy!
+
+Now, I must get back to my retirement.

+\section{Introduction}
+
+We often see in HTML pages or in compiled executable applications, form
+fields (text fields, input fields) that require user input. The untouched
+field has text within it informing the user of the nature of the data to be
+entered into the field. This, usually, grayed hint immediately disappears
+when the user focus the cursor on the field. We illustrate the concept with
+an example or two.
+\begin{quote}
+    \textField[\textColor{\matchGray}
+       \TU{Enter your first name so I can get to know you better}
+       \AA{\AAFormat{\FmtToGray{First Name}}
+       \AAKeystroke{\KeyToGray}
+       \AAOnFocus{\JS{\FocusToBlack}}
+       \AAOnBlur{\JS{\BlurToBlack}}
+    }]{NameFirst1}{2in}{11bp}\vcgBdry[\medskipamount]
+    \textField[\textColor{\matchGray}
+       \TU{Enter your favorite date, in the indicated format}
+       \AA{\AAKeystroke{AFDate_KeystrokeEx("yyyy/mm/dd");\r\KeyToGray}
+       \AAFormat{AFDate_FormatEx("yyyy/mm/dd");\r\FmtToGray{yyyy/mm/dd}}
+       \AAOnFocus{\JS{\FocusToBlack}}
+       \AAOnBlur{\JS{\BlurToBlack}}
+    }]{DateField1}{1in}{11bp}\cgBdry[1.5em]
+    \pushButton[\CA{Reset}
+        \TU{Press to clear to clear all fields.}
+        \A{\JS{this.resetForm();}}]{reset}{}{11bp}
+\end{quote}
+    Of course, the usual tooltips may also be provided.\medskip\noindent
+
+    It is not natural for Adobe form fields to do this, it takes some support
+    code for it to work properly; scripts for the Keystroke, Format, OnFocus,
+    and OnBlur events are needed.
+
+\section{Package options}
+
+Without passing any options, the \pkg{eforms} package of \AEB, dated
+2017/02/27, is required and a document JavaScript function
+\texttt{AllowCalc()} is automatically embedded in the document; however there
+are options to modify this default setup.
+\begin{description}
+    \item[\texttt{usehyforms}] By default, this package requires
+        \pkg{eforms}, dated 2017/02/27; however, if you are more
+        comfortable using the form fields of \pkg{hyperref}, specify the
+        option \texttt{usehyforms}.\footnote{\pkg{eforms} and
+        \pkg{hyperref} form fields can be used in one document.} When
+        \texttt{usehyforms} is specified, \pkg{insdljs} dated 2017/03/02 or
+        later is required. This requirement is to support the
+        \texttt{usealtadobe}, discussed next.
+    \item[\texttt{nocalcs}] If this option is taken, the document
+        JavaScript function \texttt{AllowCalc()} is not embedded in the document. The
+        implications are that you are not using any calculation fields.
+    \item[\texttt{usealtadobe}] If you have the \app{Acrobat} application,
+        you can edit form fields. When you write custom formatting scripts
+        (as does this package) using Adobe's built-in functions, such as
+        \texttt{AFNumber\_Keystroke} and \texttt{AFNumber\_Format}, the
+        user-interface for editing the custom script is not available. The
+        \texttt{usealtadobe} option is passed to \pkg{insldjs};
+        \pkg{insdljs}, in turn, inputs alternate names for the common
+        \app{Adobe} built-ins. Refer to
+        \hyperref[s:altadobfuncs]{Section~\ref*{s:altadobfuncs}} for more
+        information.
+
+    \item[\texttt{nodljs}] When this option is specified, there are no
+        requirements placed on this package; that is, neither \pkg{eforms}
+        nor \pkg{insdljs} are required.
+\end{description}
+
+\paragraph*{Demo file:} \texttt{gh-eforms.tex,\;gh-hyperref.tex}. The latter file
+uses the \opt{usehyforms} option (and \pkg{hyperref} form fields), while the former uses the \pkg{eforms} package.
+
+\section{Creating a form field with a gray hint}
+
+In this documentation, we use \pkg{eforms} form fields to illustrate concepts, the demonstration file
+\texttt{gh-hyperref.tex} has the form field markup for the case of \pkg{hyperref} forms.
+
+There are two cases: (1) an ordinary variable text form field (this includes
+text fields and editable combo boxes) with no calculate script; (2) same as
+(1), but the field has a calculate script.
+
+\subsection{Variable text field, no calculate script}
+
+When there is no calculate script, to obtain a gray hint, it is necessary to
+supply scripts for the Format, Keystroke, OnFocus, and OnBlur events. The
+scripts are all defined in the \pkg{grayhints} package. In addition, the
+color of the text in the text field must be appropriate. We illustrate,
+\begin{Verbatim}[xleftmargin=\parindent,commandchars=!(),numbers=left,numbersep=3bp,fontsize=\small]
+\textField[!color(gray)\TU{Enter your first name so I can get to know you better}
+    \textColor{\matchGray}\AA{%
+    \AAKeystroke{\KeyToGray}
+    \AAFormat{\FmtToGray{First Name}}
+    \AAOnFocus{\JS{\FocusToBlack}}
+    \AAOnBlur{\JS{\BlurToBlack}}
+}]{NameFirst}{2in}{11bp}
+\end{Verbatim}
+By default, the text color is black and the grayed hint text is light gray.
+The tool tip (\cs{TU}) is grayed out, as it is optional. In line~(2) we match
+the color for the text to the gray color using the command \cs{matchGray} of
+\pkg{grayhints}. Within the argument of \cs{AA}, the \cs{AAFormat},
+\cs{AAKeystroke}, \cs{AAOnFocus}, and \cs{AAOnBlur} scripts are inserted.
+\begin{quote}
+\begin{description}
+    \item{Keystroke Script:} In line~(3), \cs{KeyToGray} is placed within
+        the argument of \cs{AAKeystroke}. This script changes the color
+        of the text to gray when the field is empty.
+    \item{Format Script:} The script snippet \cs{FmtToGray} takes a
+        single argument, which is the text of the hint. In line~(4)
+        the hint is `First Name'.
+    \item{OnFocus Script:} The code snippet \cs{FocusToBlack} is inserted
+        into the argument of \cs{OnFocus}, as seen in line~(5). When the
+        field comes into focus, this script changes the color to the
+        normal color (usually black).
+    \item{OnBlur Script:} In line~(6), the \cs{BlurToBlack} script is
+        placed within the argument of \cs{OnBlur}, in the manner
+        indicated. When the field loses focus (is blurred), the script
+        changes the color of text to gray if the field is empty or to
+        its normal color (usually black), otherwise.
+\end{description}
+\end{quote}
+The \pkg{hyperref} form field counterpart to the above example is,
+\begin{Verbatim}[xleftmargin=\parindent,commandchars=!(),numbers=left,numbersep=3bp,fontsize=\small]
+\TextField[name={NameFirst},
+    height=11bp,width=2in,
+    color=\matchGray,
+    keystroke=\KeyToGray,
+    format=\FmtToGray{First Name},
+    onfocus=\FocusToBlack,
+    onblur=\BlurToBlack]{}
+\end{Verbatim}
+The two fields appear side-by-side:
+\begin{quote}
+\textField[\autoCenter{n}\textColor{\matchGray}
+    \TU{Enter your first name so I can get to know you better}
+    \AA{\AAFormat{\FmtToGray{First Name}}
+        \AAKeystroke{\KeyToGray}
+        \AAOnFocus{\JS{\FocusToBlack}}
+        \AAOnBlur{\JS{\BlurToBlack}}
+}]{NameFirst2}{2in}{11bp}\cgBdry[0.5em]
+\TextField[name={NameFirst3},
+    height=11bp,width=2in,
+    color=\matchGray,
+    keystroke=\KeyToGray,
+    format=\FmtToGray{First Name},
+    onfocus=\FocusToBlack,
+    onblur=\BlurToBlack]{}\cgBdry[0.5em]
+\pushButton[\CA{Reset}\autoCenter{n}
+    \TU{Press to clear to clear all fields.}
+    \A{\JS{this.resetForm();}}]{reset}{}{11bp}
+\end{quote}
+Both fields appear in the `default' appearance.
+
+
+\subsection{Variable text field, with calculate script}
+
+If you want to make calculations based on entries in other fields, you will need
+the code snippet \cs{CalcToGray} as part of your calculate script.
+\begin{Verbatim}[xleftmargin=\parindent,commandchars={!~@},numbers=left,numbersep=3bp,fontsize=\small]
+\textField[!color~gray@\TU{The total for first and second integers}
+    \textColor{\matchGray}\AA{%
+    \AAKeystroke{AFNumber_Keystroke(0,1,0,0,"",true);\r\KeyToGray}
+    \AAFormat{AFNumber_Format(0,1,0,0,"",true);\r\FmtToGray{Total}}
+    \AACalculate{var cArray=new Array("Integer");\r
+        if(AllowCalc(cArray))AFSimple_Calculate("SUM", cArray );\r
+        \CalcToGray}
+    \AAOnFocus{\JS{\FocusToBlack}}
+    \AAOnBlur{\JS{\BlurToBlack}}}
+]{TotalNumbers}{1in}{11bp}
+\end{Verbatim}
+The use of \cs{r} is optional, the author uses this to format the script
+within the user-interface of \app{Acrobat}. The \cs{textColor} (line~(2)),
+\cs{AAOnFocus} (line~(8)), and \cs{AAOnBlur} (line~(8)) are the same as earlier presented.
+Several comments are needed for the \cs{AAKeystroke}, \cs{AAFormat} and \cs{AACalculate} lines.
+\begin{itemize}
+    \item This is a number field, so we use the built-in functions
+        \texttt{AFNumber\_Keystroke} and \texttt{AFNumber\_Format} provided
+        by the \app{Adobe Acrobat} and \app{Adobe Acrobat Reader}
+        distributions. In lines~(3) and~(4), the \cs{KeyToGray} and
+        \cs{FmtToGray} code snippets follow the built-ins.\footnote{As a general rule,
+        the code snippets \cs{KeyToGray}, \cs{FmtToGray}, and
+        \cs{CalcToGray} should inserted after any built-in functions.}
+    \item For the Calculate event, special techniques are used. We define
+        an array \texttt{cArray} (line~(5)) consisting of the names of all
+        the dependent fields we use to calculate the value of this field.
+        In line~(6), we make the calculation (\texttt{AFSimple\_Calculate})
+        only if the document JavaScript function \texttt{AllowCalc(cArray)}
+        returns true. The function returns true only if at least one of the
+        fields is not empty. Following the calculation comes the code
+        snippet \cs{CalcToGray}; this changes the text color to gray if the
+        field is empty and to the normal color (usually black) otherwise.
+
+        The function \texttt{AllowCalc()} is defined for all options except
+        for the \opt{nodljs} option.
+\end{itemize}
+Let's go to the examples. Build three fields (four actually), in the first two
+enter integers, the other two fields compute their sum.

+\end{quote}
+Enter numbers into the first two text fields (\ding{172} and \ding{173}), the
+totals of these two fields appear in the last two fields (\ding{174} and
+\ding{175}). Total field \ding{174} uses the recommended script
+\texttt{if(AllowCalc(cArray)} (see line~(6) above), whereas field \ding{175}
+does not. Initially, they both behave the same way until you press the reset
+button. For field \ding{174} the gray hint appears, for field \ding{175} the
+number zero (0) appears. This is because the calculation was allowed to go
+forward, and the calculated value is zero even through none of the dependent
+fields have a value. If you want the gray hint in the total field, you must
+use the conditional \texttt{if(AllowCalc(cArray)}.\footnote{Hence, don't use the \opt{nodljs} option.}
+
+\subsection{Changing the colors for gray hints}
+
+For the fields in which the gray hint scripts are used, there are two colors
+that are relevant, the normal color (defaults to black) and the gray color
+(defaults to light gray). The command
+\cs{normalGrayColors\darg{\ameta{normalcolor}}\darg{\ameta{graycolor}}} sets
+this pair of colors. The arguments for \cs{normalGrayColors} are JavaScript
+colors; they may be in any of the following four forms: (1) a JavaScript
+color array \texttt{["RGB",1,0,0]}; (2) a predefined JavaScript color, such
+as \texttt{color.red}; (3) a declared (or named) {\LaTeX} color such as
+\texttt{red}; or (4) a non-declared {\LaTeX} color such as
+\texttt{[rgb]\darg{1,0,0}}. If the package \pkg{xcolor} is not loaded, only
+methods (1) and (2) are supported.
+
+The package default is
+\cs{normalGrayColors\darg{color.black}\darg{color.ltGray}}. The predefined
+JavaScript colors are,
+\begin{quote}
+%    \setlength\tabcolsep{3pt}
+    \setlength{\extrarowheight}{1pt}
+    \begin{tabular}{>{\ttfamily}l>{\ttfamily}l>{\ttfamily}l}
+    \multicolumn{3}{>{\sffamily}c}{Color Models}\\\hline
+    \multicolumn{1}{>{\sffamily}c}{GRAY}&
+    \multicolumn{1}{>{\sffamily}c}{RGB}&

+    color.dkGray&color.blue\\
+    color.gray\\
+    color.ltGray
+    \end{tabular}
+\end{quote}
+All these colors are defined in the {\LaTeX} color packages, except for possibly \texttt{dkGray},
+\texttt{gray}, and \texttt{ltGray}. These three are defined in \pkg{grayhints}.
+
+We repeat the `First Name' example with different declared colors. We begin by declaring,
+\begin{Verbatim}[xleftmargin=\parindent,fontsize=\small]
+\normalGrayColors{blue}{magenta}
+\end{Verbatim}
+then build a `gray hinted' field,
+\begin{quote}\previewOff\normalGrayColors{blue}{magenta}%
+    \textField[\textColor{\matchGray}
+       \TU{Enter your first name so I can get to know you better}
+       \AA{\AAFormat{\FmtToGray{First Name}}
+       \AAKeystroke{\KeyToGray}
+       \AAOnFocus{\JS{\FocusToBlack}}
+       \AAOnBlur{\JS{\BlurToBlack}}
+    }]{NameFirst4}{2in}{11bp}\cgBdry[1em]
+\pushButton[\CA{Reset}
+    \TU{Press to clear to clear all fields.}
+    \A{\JS{this.resetForm();}}]{reset}{}{11bp}
+\end{quote}
+
+\subsection{Remarks on the
+    \texorpdfstring{\protect\opt{usealtadobe}}{usealtadobe} option}\label{s:altadobfuncs}
+
+The \opt{usealtadobe} option is useful for developers who have the
+\app{Adobe} application and who wish to develop and test scripts that extend
+in the current work. The \opt{usealtadobe} option inputs from \pkg{insdljs} the following
+alternate names. As a general rule, all Adobe built-in format, validate, and calculation functions
+that begin with `AF' are given alternate names that begin with `EF'. More specifically, the table
+below lists the effected functions.
+\begin{quote}
+\begin{tabular}{>{\ttfamily}l>{\ttfamily}l}

+\end{figure}
+
+\hyperref[fig:AltAdbFncs]{Figure~\ref*{fig:AltAdbFncs}} shows the impact of using the `EF' functions. On the left,
+\texttt{AFNumber\_Format} is used to format a number field that uses gray hints using the code
+\begin{Verbatim}[xleftmargin=\parindent]
+AFNumber_Format(0,1,0,0,"",true)\r\FmtToGray
+\end{Verbatim}
+As can be seen in sub-figure\,(a), or more accurately not seen, the code is
+not seen through the user-interface of \app{Acrobat}. In sub-figure\,(b) the
+underlying code is seen (and therefore editable through the user-interface)
+because the `EF' version of the function was used:
+\begin{Verbatim}[xleftmargin=\parindent]
+\try{EFNumber_Format(0,1,0,0,"",true)}catch(e){}\r\FmtToGray
+\end{Verbatim}
+Note this code is wrapped in a \texttt{try/catch} construct; this is
+optional. The \pkg{insdljs} package defines a helper command \cs{dlTC} to do the wrapping for you:
+\begin{Verbatim}[xleftmargin=\parindent]
+\dlTC{EFNumber_Format(0,1,0,0,"",true)}\r\FmtToGray
+\end{Verbatim}
+When using \app{pdflatex} or \app{xelatex}, \texttt{try/catch} appears not to
+be needed, but when \app{Adobe Distiller} is used, \app{Acrobat} throws an
+exception when the file is first created. The \texttt{try/\penalty0catch} suppresses
+(catches) the exception.
