This applet is an interactive cross-words grid for web pages. The
source code is kind of open-source (modified GPL licence). I am fed up
with commercial sites which used the previous version which was under
pure GPL licence without giving me any buck. So now, basically you can
use it on non-profit sites, and you can modify it and distribute it as
long as you keep the same licence. For any other usage, please contact
me.

You can use the arrows to move the cursor in the grid. The ENTER key
changes the cursor mode (horizontal or vertical), the BACKSPACE key
deletes the characters and the SPACE key shows the definition of the
word the cursor is on. The Check word button checks if the word the
cursor is on is correct, and locks the letters if it is, and the Give
word gives you the solution for the word the cursor is on and also
lock the letters.

A color code indicates the status of each letter. The black ones have
no special status, the red ones are those obtained using the "give
word" button, the green ones were checked before the grid was finished
using the "check word" button (yeah, this is the beginning of
cheating), and the blue ones are those found by yourself. The letters
become red or green as soon as you use the buttons, and blue when you
type the last letter and all are correct.

The <APPLET> tag contains the parameters CODEBASE wich indicates the
name of the directory containing the .class files, CODE which
indicates the name of the main .class file, and WIDTH and HEIGHT wich
indicate the size of the rectangle containing the applet. The part of
the HTML file beetween the <APPLET> and the </APPLET> tags is
displayed by the browser if it can't run Java applications. In
general, you put there an error message.

Then come the tags <PARAM> that contain the values of the various
parameters specific of the applet. For this one, you have to precise
the following ones :

 - BGCOLOR is the color of the background of the gride. It's an
   integer which value is r*256*256 + v*256 + b where r, v and b are
   the three color components, normalized beetween 0 and 255.

 - GRIDWIDTH and GRIDHEIGHT contain the number of columns and the
   number of rows of the gride.

 - CONTENT is a caracter strings containing the solution of the
   gride. Letter after letter, line after line. The '.' indicates a
   black square.

 - FONT is the font for the gride.

 - FONTSIZE is the font size for the gride.

 - SMALLFONT is the font for the row/column coordinates.

 - SMALLFONTSIZE is the font size for the row/columns coordinates.

 - CHECKWORDLABEL is the string to put in the button used to check the
   word at the cursor's location. If this parameter is not specified,
   the button does not appear.

 - GIVEWORDLABEL is the string to put in the button used to give the
   word at the cursor's location. If this parameter is not specified,
   the button does not appear.

 - DEFINITIONS contains the definitions of the words of the grid. This
   is optional and the definition-area will be activated only if this
   parameter is given. This string first indicates the size of the
   definition area, and then the word definitions, each of them
   starting with the coordinates of the first character of the word in
   the grid. See the example for the exact syntax.

So, for the gride above for instance, I have in my HTML file the
following lines (my .class files are in a class/ directory) :

<APPLET CODEBASE="class" CODE="Words.class" WIDTH=400 HEIGHT=200>
<PARAM NAME="BGCOLOR" VALUE="15724527">
<PARAM NAME="GRIDWIDTH" VALUE="4">
<PARAM NAME="GRIDHEIGHT" VALUE="4">
<PARAM NAME="CONTENT" VALUE="bu.aetret..relle">
<PARAM NAME="FONT" VALUE="Courier">
<PARAM NAME="FONTSIZE" VALUE="24">
<PARAM NAME="SMALLFONT" VALUE="Courier">
<PARAM NAME="SMALLFONTSIZE" VALUE="20">
<PARAM NAME="CHECKWORDLABEL" VALUE="Check word">
<PARAM NAME="GIVEWORDLABEL" VALUE="Give word">
<PARAM NAME="DEFINITIONS" VALUE="20x4/horizontal/a1:Ne coulera plus/b1:Une bonne question/d1:Pas lui/vertical/a1:Elle fait l'homme/a2:Pas besoin d'être comme a pour ne plus trouver cette clef/a4:Ainsi, il respire mieux">
