HeadLiner

You can access the setFileName(), start(), stop(), setBorder(), setbgColor(), 
setfgColor(), and setScrollDelay() functions from within JavaScript:


BGColor = background color
FGColor = foreground color
 color = rrggbb where rr is red, gg is green, bb is blue
         uses base 16 (hexadecimal)
         such that ff is max, and 00 is least
         example:  ff0000 is all red, no green, and no blue
                   00ff00 is no red, all green, and no blue
                   7f7f7f is gray

ScrollDelay parameter MUST BE 6 DIGITS
            interpreted as base 10 
Specifies delay value for scrolling text
default is 001000 (about 1 second)

Border parameter (1= yes, 0 = no)
puts a border (in foreground color) around the applet


HeadLiner is a free applet for use in your webpages!

Follow these steps to put the scrolling headlines on your pages:

1) Shift-Click here to download HeadLiner.class

2) Upload the HeadLiner.class to your webpage.

3) Create a text file named "headlines.txt" which will contain your scrolling
   headlines.  Be sure to use notepad or dos edit since wordprocessing programs
   like Microsoft Word will insert hidden characters which will really screw
   things up if you're not careful! (You can also specify a name other than
   "headlines.txt" with the FileName applet parameter.  See below.)

4) Upload your "headlines.txt" file to your webpage in the same directory
   containing your HeadLiner.class file.

5) Insert the appropriate html code to tell the browser to load the HeadLiner
   applet and to tell the applet which user-definable parameters you want it
   to use.  

Here are links to the .txt files:
headlines.txt
alt.txt

Here's the html code used for this page:

< applet code = "HeadLiner.class" height = "110" width = "150"> 

< param name=FGColor value="000000"> 
< param name=BGColor value="ffffff"> 
< param name=ScrollDelay value = "000100"> 
< param name=Border value = "1"> 
< param name=FileName value ="headlines.txt">
< /applet> 

The following five (5) parameters are supported:
1) FGCOLOR -foreground color to use for displaying your text (default: black)
2) BGCOLOR -background color for the applet (default: white)
3) ScrollDelay -the higher this number the slower the applet will scroll the text

All of the above parameters MUST use six (6) digits!

4) FileName -the name of the text file containing the headline text (default: headlines.txt)
5) Border -Use "1" if you want a border, "0" if you do not.  The border will be
drawn using the foreground color. (default: No border)

A few words about color selection:
Colors are expressed as rrggbb where rr is the red component, gg is the green
component, and bb is the blue component.  These values are hexadecimal, such
that 00 = 0 (least), ff = 255 (most).  Below are just a few examples:

000000  black (no red, no green, no blue)
ffffff  white (max red, max green, max blue)
ff0000  red   (max red, no green, no blue)
00ff00  green (no red, max green, no blue)
0000ff  blue  (no red, no green, max blue)
7f7f7f  gray  (med red, med green, med blue)

The ScrollDelay is the actual milliseconds that the applet's animation thread
will sleep in between animations.  However, depending upon the speed of the
client system and the size of the applet, the delay will probably be actually
higher than what is used for this parameter.  In other words, the text will
scroll slower on most machines if you specify a large size for the applet,
even though you specify a very low ScrollDelay parameter.  If you find that the
text is scrolling too slowly for your tastes, try setting the ScrollDelay
parameter to 000000.  You can also try using smaller values for the height and
width applet parameters.  Experiment with different combinations until you get
the look and feel you desire.  Remember, this parameter MUST be SIX (6) digits!

Each line in your headlines.txt file must be separated by a hard return.  This 
is because the applet makes no attempt to wrap the text contained within the 
headlines.txt file.  It is up to you, the web designer, to format the text so
it will fit within the applet boundaries, otherwise part of your text might not
be displayed.

JavaScript can also access these parameters to provide dynamic modification in 
response to user actions, such as clicking a button, as demonstrated above.  Here
is the script used to create the buttons above:


< form >
< input type=button value="Start" onClick = "document.HeadLiner.start()" >
< input type=button value="Stop" onClick = "document.HeadLiner.stop()" >
< input type=button value="Blue Text" onClick = "document.HeadLiner.setfgColor('0000ff')" >
< input type=button value="Red Background" onClick = "document.HeadLiner.setbgColor('ff0000')" >
< input type=button value="Fast Scroll" onClick = "document.HeadLiner.setScrollDelay('000001')" >
< input type=button value="Slow Scroll" onClick = "document.HeadLiner.setScrollDelay('001000')" >
< input type=button value="Use alt.txt" onClick = "document.HeadLiner.setFileName('alt.txt')" >
< input type=button value="Kill Border" onClick = "document.HeadLiner.setBorder('0')" >
< input type=text value = "ffffff" name="TextColor" defaultValue="ffffff">
< input type=button value="setfgColor" onClick="document.HeadLiner.setfgColor(TextColor.value)">
< input type=text value = "ffffff" name="BackgroundColor" defaultValue="ffffff">
< input type=button value="setbgColor" onClick="document.HeadLiner.setbgColor(BackgroundColor.value)">
< input type=button value="Show Border" onClick = "document.HeadLiner.setBorder('1')">

< br >
< /form >

There's no requirement that the above public functions have to be accessed only
as a response to a user clicking on a button.  You could, for example, set up a 
menu with JavaScript to switch the .txt files based upon the users' menu selections.
