Tree Menu - Copyright (C) by Fabio Ciucci 1998/99


This applet is a navigational menu, which emulates the windows tree 
scructures. It can display unlimited menus and submenus, with any kind
of icons. The link feature works only when you are registered by paying
for the shareware. 

This applet contains code by Dolf van der Schaar who is used under a 
licence.

INSTRUCTIONS.

The following instructions describe how to change parameters:

Attempting to change the "credits" parameter will disable the applet.

To activate the reg parameters read the shareware registration notes.
In the "regcode" parameter, place the registration code you purchased 
from the author. If the code is correct and the applet is run from
the registered domain name, you can use "link" parameters to link to a URL
when the applet is "clicked".

If you set "regnewframe" to "YES", you can specify a specific frame location
for the menu links:

"_blank"  : To load the link in a new blank unnamed browser window.
"_self"   : To load the link into the same window the applet occupies.
"_parent" : To load the link into the immediate FRAMESET parent.
"_top"    : To load the link into the top body of the window.

You can also set a custom frame name, such as "myframe1".

With the parameters "scrollSpeedInGoing" and "scrollSpeedOutGoing" you can
determine the speed of tree branches closing and opening.

If you want, you can enable a bouncing effect when you open and close
the branches of a tree. To control this, you set the "numberOfBouncesInGoing"
and the "numberOfBouncesOutGoing", and if those are more than "0", the
relative "bounceGravity" and "bounceAmplitude" have to be set. 

If you set "bounceGravity" to 50, for example, when bouncing the second time
the amplitude will be 50% of the first bounce, and the third time it will
be 50% of the second time, or you can say 25% of the first bounce.

The "bounceAmplitude" is the amplitude in percentages of the original
bounce size. When it is set to 200, the bounce will result in twice
as big as the original size.

The visual aspect of the tree can be altered determining the text font
name, with "treeFont" parameter, and the style with "treeBold" and
"treeItalic" parameters, which can be set to "YES" or "NO".

The font size can be changed using "treeFontSize".

The colour of the scroll bars and borders can be set with "systemColor"
parameter, using an hexadecimal 0x00rrggbb format, like the one used for
html, but without the leading "#".

Using same format, the background colour is controlled with "backgroundColor"
parameter, the text colour with "foregroundColor" parameter.

If a background image is loaded, the "backgroundColor" parameter is ignored.

When the text is selected, "foregroundColorSelection" is the colour to be 
displayed, and "backgroundColorSelection" will be the one under the
selected text (if a background image is present, it will be in transparency).

An iportant parameter is "filterColor": this colour is used to filter the
icon images (all them), to decide what is the TRANSPARENT COLOUR.

On the sample icons included, the transparency filter colour is "ffffff",
in other terms the full white (red=255, green=255, blue=255).

Darker whites will not be considerer transparent, only this one. You can
change the transparency colour filter, but then be sure to provide
icon images where the selected colour has to be the transparent one.

Note: if you load transparent gif images as icons, the transparency of
gif will should be considered transparent.

If you want an image as background, place it's name in the "backImage"
parameter. Note: the image can be of any size, and if smaller than menu
applet area, it will be TILED to fill it.

The "borderStyle" parameter determine the borders presence and style.
With a value of "0", no borders are displayed.
With a value of "1", the border is 1 pixel wide.
With a value of "3", the border is 3 pixels wide.

The "scrollBarStyle" determine the size of scrollbars (who appears when
the menu items become bigger than applet area).
With a value of "0", the scrollbars are 11  pixels wide.
With a value of "1", the scrollbars are 16  pixels wide.

Setting "autoHighLight" parameter to "yes", the items will be highlighted
simply when mouse is over them. Setting it to "no", a click will be required
to highlight an item.


*****

The floating mode:

Optionally, you can enable the "floating window" mode.
The treemenu applet, then, will appear in a floating external window, and will
leave free all the other frame space on the web site.
But, you still have to create a small horizontal or vertical frame (maybe
1 or 2 pixels large), containing the applet, 1 pixel large.

To enable this mode:

1) Set "floatmode" to "YES"
2) Copy the applet width in the "floatw" parameter
3) Copy the applet height in the "floath" parameter
4) Set the applet width=1 and height=1

At this point, you just have to customize it using those parameters:

The window title must be written in the "floatitle" parameter.

The starting X and Y position where window should apper, must be written
in the "floatx" and "floaty" parameters. Note: the coordinates are relative
to user screen, so result can change depending on screen resolution.

If you want the window to be always on top and visible, set the "floatinfront"
parameter to "YES". This could be useful for someone, and annoying for others.

Note: the "floatinfront" option will have no effect on some versions of
Internet Explorer.


*****

Menu System:

Each item needs an icon. You load all the required icons with the Icon
parameters, just increase the index, there are no limitations:

<param name="Icon0" value="fo_win1.gif">  ; Icon 0 image name
<param name="Icon1" value="fo_win3.gif">  ; Icon 1 image name
<param name="Icon2" value="ic_anfy.gif">  ; Icon 2 image name
...

Icons can be of 2 types: FOLDER ICONS or ITEM ICONS.

The Folder Icons should be 32x16 pixels wide, made of 2 icons: the folder
open and the folder closed. Just take a look at the fo_win1.gif, and
other fo_*.gif samples included.

The Item Icons should be 16x16 pixels wide. Just take a look at the ic_*.gif
samples included. It is possible (even if looks bad) to assign to a folder 
a 16x16 Item Icon. It is not possible to assign a 32x16 Folder Icon to an 
item.

The accepted formats are GIf and JPG, but GIF is more adaptable.

If you want transparent parts, assign to these the colour specified in
the "filterColor" parameter.

Note: GIF transparency information should work too.


Tree Structure:

Each config. line contains 4 parameters, separated by "," characters:

-parentId:  This value represents the number of its direct parent. Every item 
            has its own Id. This Id is identical to the config line number.

-Name:      This is the Text (name)label for the item/menu.

-iconId:    The number of the icon to be used. This number is the
            same number specified when loadind icons (icon0, icon1 etc.).

-Link:      The link to be opend when this item/menu is pressed.
            If the item has no links, or it's a folder, specify "u", which
            stands for "unlinked" (no links).

The menu has to start with "config0", the main parent, or the root.
All the config parameters are sequential to this, ie.: config1, config2, etc.

Look at this example:
