// *** START EDITING HERE, READ THIS SECTION CAREFULLY! ***
//
//
// Before you start, make sure you've read the "Conditions Of Use" in this HTML document
// or on my site. Anyway, this menu script is split up into several sections. They are:
//
// (1) ITEMSTYLES - These define the colour and size of menu items. Required to run.
// (2) MENU DATA - These specify the text and links in the menu. Required to run.
// (3) MENU EFFECTS - Want to remove, or change borders, shadows and animation? Edit them here,
//     or you can delete this section entirely to remove extra effects.
// (4) EVENTS - Activate the menu(s), and choose creation mode (Dynamic / Fast) etc. I recommend
//     you read it, but you only really need to change it if you want multiple menus on one page,
//     or are trying to combine this with other JavaScripts. Required to run.
// (5) OPTIONAL CODE - Extra features like adding clicking to 'sm:' items or status messages on
//     mouseover. Animation/effects functions are here too. You can skip or delete this entirely.
// (6) FRAMESET README - If you're using a frameset, read this, it explains what you need to do.



// *** (1) ITEMSTYLES ***
//
// First of all we must create ItemStyles to use in the menu. ItemStyles are a collection of
// dimensions, colours, and font/border stylesheet class names that you can 'apply' to menus
// and items later on for a consistent look. The (somewhat lengthy) syntax is:
//
// styleName = new ItemStyle(length of items, spacing after items, 'popout indicator HTML',
//  popout indicator position, padding of text within item, 'out background colour or image
//  filename', 'hover background colour or filename', 'out text stylesheet class', 'hover text class',
//  'out border stylesheet class', 'hover border class', out opacity percentage or null to make
//  it fully opaque, hover opacity percentage or null, 'CSS mouse cursor for normal items',
//  'CSS cursor for sm: and blank items');
//
// One thing that needs explaining is the popout indicator position -- you pass a positive
// integer to position it from the left of the item, and a negative integer to position it from
// the right edge of the item -- see the example code below if that doesn't make much sense.
// Pass an empty string '' as the over or out background for a transparent background.
// If you pass 'hand' as a cursor, the script automatically translates it to 'pointer' for NS6.
// All stylesheet text/border classes come from the <STYLE> tag in this document, you can change
// the font and border colours and styles used there.
//
// Here are some examples used in this menu demo, read through and see how they're formatted,
// then try tweaking some of the numbers and refreshing the page:


// 'horizontal Bar' style: menu items that use this ItemStyle are 40px wide, have 10px gaps
// between them, no popout indicator (the ">" in some menus) or popout indicator position,
// 0px padding of the text within items, #336699 background colour, a hover colour of #6699CC,
// 'highText' is the stylesheet class used for the menu text both normally and when highlighted,
// no border styles, 'null' means fully opaque items (set them to numbers between 0 and 100 to
// enable semitranslucency), and the 'hand'/'default' cursors are used for linked/submenu items.

var hBar = new ItemStyle(147, 10, '', 0, 0, '', '', 'highText', 'hitext', '', '',
 null, null, 'hand', 'default');

// The 'sub Menu' items: 22px long, 0px spacing, a 'greater than' sign for a popout indicator
// (you may wish to use an image tag?), the popout indicator is positioned 15px from the right
// edge of the item, items have 3px padding, some colours, it uses 'lowText' as the dimmed text
// class but 'highText' when it is moused over, and 'itemBorder' as the border stylesheet class.
// No opacity is used, and they have the same cursors as the above ItemStyle.

var subM = new ItemStyle(22, 0, '&gt;', -15, 3, '#000000', '#000000', 'lowtext', 'menuhitext',
 'itemBorder', 'itemBorder', 65, 65, 'hand', 'default');

// 'subBlank' is similar, but has an 'off' border the same colour as its background so it
// appears borderless when dim, and 1px spacing between items to show the hover border.

var subBlank = new ItemStyle(75, 1, '&gt;', -15, 3, '#CCCCDD', '#6699CC', 'lowText', 'highText',
 'itemBorderBlank', 'itemBorder', 30, 30, 'hand', 'default');

// The purplish 'button' style also has 1px spacing to show up the fancy border, and it has
// different colours/text and less padding. They also have translucency set -- these items
// are 80% opaque when dim and 95% when highlighted. It uses the 'crosshair' cursor for items.

var button = new ItemStyle(75, 1, '&gt;', -15, 2, '#006633', '#CC6600', 'buttonText', 'buttonHover',
 'buttonBorder', 'buttonBorderOver', 80, 95, 'crosshair', 'default');




// *** (2) MENU DATA ***
//
// Read this section VERY CAREFULLY, it explains how to arrange and tweak the menus themselves.
// To use this script you must create one or more PopupMenu() objects, that will contain all
// the menu data and settings used. This demo contains one, named 'pMenu', although you can
// have as many totally separate menus as you want on one page.
//    Next we add menus and items to the object, using its startMenu() and addItem()
// commands. Each menu object MUST contain one menu named 'root', which is the first, always
// visible menu. The syntax of the startMenu() command is:
//
// startMenu('menu name', Vertical menu (true/false)?, left, top, width, default ItemStyle
//  for items in this menu, optional parent frame/window or layer in which this menu resides);
//
// In order, the parameters are a name for the menu like 'root' or 'mFile', which you can use to
// refer to this menu from other menus, to pop it out.
//    Next, pass 'true' if you want this to be a vertical stacked menu or 'false' if you want this
// to be a horizontal menu bar. You can orientate each menu differently this way.
//   The Left and Top positions allow you to locate this menu either absolutely from the page or
// relative to menu item that pops it out. If you want to offset this menu from the item that pops
// it out, set the positions as NUMBERS, e.g. 130, 10 would put the upper-left corner of this menu
// 130px across and 10px down from the upper-left corner of the item that popped it out.
//   If you put '130', '10' as positions in QUOTES, you can position the menu from the upper-left
// corner of the whole page. These strings can also include formulae to centre or scroll the menu,
// examples are included later on. Note: the 'root' menu is always positioned from the page corner.
//    The 'width' depends on the orientation of the menu -- for vertical menus it's the width,
// for horizontal menus it is the height. Basically, it's the constant dimension for all the items.
//    The parent window or layer parameter is optional, if not specified the current window is
// used -- this example does not use frames. See the frameset example file if you're using them,
// they are strings that when evaluated return a reference, like 'window.top'.
//
// Once you have created a menu, you add items to that menu using the addItem() command.
// You must give it THREE compulsory parameters: 1) The HTML/text to display in the item. 2) The
// menuname/filename/URL the item activates. 3) The action type or target frame of that item.
// All other parameters are optional -- you can override the menu's default ItemStyle with the
// item's own, and optionally override that was well by specifying a list of parameters in the
// same order as an ItemStyle, to give each item its own dimensions / colours etc.
// See the example menu below for an example of these extras...
//
// addItem('Text', 'URL or menuname', 'action type', optional ItemStyle, length, spacing,
//  'popout indicator', popout indicator position, etc... in the same order as ItemStyles);
//
// The third parameter, 'action type', tells the script what to do with the second parameter.
// You can tell the script to load a file in the current window or a particular frame, tell it
// to pop out a menu, or tell it to run a JavaScript command. You do these like this:
//
// addItem('Text', 'file.html', ''); //blank means opens up 'file.html' in the current window.
// addItem('Text', 'file.html', 'parent.content');  //opens 'file.html' in a frame named 'content'.
// addItem('Text', 'menuName', 'sm:');  //pops out another submenu called 'menuName'.
// addItem('Text', 'alert("Hello")', 'js:');  //runs a JavaScript command when clicked.
//
// Frame names should be valid JavaScript syntax, e.g. 'top.frameName' or 'parent.popupWin',
// evaluated from the the window containing the main script (this one). Also, this system means
// 'sm:' items aren't normally clickable. If you do want to add click or mouseover actions to
// items, see the "Optional Code" section of the script below.
// 
// See the example below if this seems complicated, it's quite easy once you get the hang of it.
// Thanks to Martin J. Cole for originally suggesting the syntax!
// If you want more information, there's a FAQ (Frequently Asked Questions) section on my
// site: http://www.twinhelix.com, on the 'Popup Menus' page, or try the 'Site Forums" perhaps.



// A PopupMenu() object must be passed its own name so it can reference itself when the menu
// is active. We also use a 'with' block to work with its properties and functions below.
var pMenu = new PopupMenu('pMenu');
with (pMenu)
{

// *** MOVE OR CENTRE THE MENU HERE ***

// To centre it, or scroll with the window etc, just include a global variable or formula as one
// of the positions. This script includes my page object, which has several useful methods, namely
// 'page.winW()', 'page.winH()', 'page.scrollY()' and 'page.scrollX()'. These return the current
// dimensions of the visible window area and the scroll position of the window, which can be
// used to position menus however you want. Try replacing the first startMenu() below with one of
// these commented lines, and scroll/resize the window to see how they work.

//startMenu('root', false, 'page.winW()/2 - pMenu.menu.root[0].menuW/2', 0, 17, hBar); // Centres.
//startMenu('root', false, 10, 'page.scrollY()', 17, hBar); // Floats with window as you scroll.
//startMenu('root', false, 10, 0, 17, hBar, 'frameName'); // To create in subframe.

// The 'root' menu is horizontal, positioned at (x = 10, y = 0) and is 17px high, and items
// by default use the colours and dimensions in the 'hBar' ItemStyle defined above.
// This menu is also positioned over a similarly-coloured table in the HTML document above.
// startMenu('root', false, 'page.winW()/2 - pMenu.menu.root[0].menuW/2', 106, 19, hBar); // Centres.
startMenu('root', false, 6, 106, 19, hBar); // 

// The text is a space then 'File', and this item pops out the 'mFile' submenu when moused over
// as we've set 'sm:' as the action type. If you want to assign a click action (e.g. navigating to
// a file) to one of these 'sm:' items, see the 'Optional Code' section below.

// has 0px spacing after it, and a lesser-than-sign popout indicator positioned 3px from the left
// edge of this item. Note that the parameters after the ItemStyle name are in the same order as
// the ItemStyle command itself, and you can have as many as you want (e.g. background colours).
//addItem('&nbsp; &nbsp; About', 'mAbout', 'sm:', subM, 22, 0, '&lt;', 3);

// This is across but not down... a horizontal popout.
startMenu('mReopen', true, 85, 0, 120, button);

// the whole menu comes from a JavaScript function in the "Menu Effects" section.
startMenu('mConvert', true, 85, 0, 80, subBlank);

// You can assign 'oncreate' events to specific menus. By default, the script has only one for
// the root menu that shows it when it is created. You may wish to change it to something like the
// following, which uses the animation function to show the menu, or delay its show altogether.
//menu.root[0].oncreate = function()
// { this.visNow=true; pMenu.position('root'); pMenu.showMenu('root') }

// Uncomment these lines to make specific menus show popouts on click rather than on mouseover.
//menu.root[0].subsOnClick = true;
//menu.mFile[0].subsOnClick = true;

// You can also customise hide or show delays (in milliseconds) to the menus. Defaults are:
//showDelay = 0;
//hideDelay = 500;
// Specify hideDelay as zero if you want to disable autohiding, and showDelay as a couple of
// hundred if you don't want the menus showing instantaneously when moused over.

// End of 'with (pMenu)' block. That's one menu object created, now we have to activate it...

}


// You can create another menu object here if you want multiple menus on a page.
// Every menu object MUST have a menu named 'root' in it, as that's always visible.
// You can name the other menus in it anything you want.

//var anotherMenu = new PopupMenu('anotherMenu');
//with (anotherMenu)
//{
// startMenu('root', .....);
// ... make menus here ...
//}

// Then remember to add it to the event section below...







// *** (3) MENU EFFECTS AND ANIMATION ***


// Now you've created a basic menu object, you can add optional effects like borders and
// shadows to specific menus. These functions are found in the "Optional Code" section
// below, you can edit them or delete them entirely if you don't want to use them, with
// no harm to the rest of the script itself.


// Add a border to an all menus using a specified ItemStyle. The syntax is:
// addMenuBorder(menuObject, ItemStyle,
//  opacity of border, 'border colour', border width, 'padding colour', padding width);
// Opacity is a number from 0 to 100, or null for no filter, like the ItemStyles.

addMenuBorder(pMenu, window.subBlank,
 null, '#666666', 1, '#CCCCDD', 2);


// Apply a dropshadow to specific menus again. The syntax is similar, but later on you
// pass arrays [...] for each layer of the shadow you want. I've used two grey layers
// here, but you can use as many or as few as you want. The syntax for the layers is:

// [opacity, 'layer colour', X offset, Y offset, Width Difference, Height difference]

// Opacity is from 0 to 100 (or null for no filter), and the X/Y offsets are the
// distance in pixels from the menu's top left corner to that shadow layer's corner.
// The width/height differences are added or subtracted to the current menu size, for
// instance the first layer of this shadow is 4px narrower and shorter than the menu
// it is shadowing.

addDropShadow(pMenu, window.subM,
 [40,"#333333",6,6,-4,-4], [40,"#666666",4,4,0,0]);
addDropShadow(pMenu, window.subBlank,
 [40,"#333333",6,6,-4,-4], [40,"#666666",4,4,0,0]);


// Add animation to the 'pMenu' menu object for supported browsers.
// Opera doesn't support clipping so we turn it off, and Mozilla versions prior to
// 1.x (such as Netscape 6) are too slow to support it, so disable there too.
// If you don't want animation, delete this entirely, and the menus will act normally.
// Change the speed if you want... it's the last number, between -100 and 100, and is
// defined as the percentage the animation moves each frame.
// The 'menuAnim' function is in the "Optional Code" section below, edit if you want to,
// I've put in a few extra tweaks in there like fading transitions if you're interested.

if (!isOp && navigator.userAgent.indexOf('rv:0.')==-1)
{
 pMenu.showMenu = new Function('mN','menuAnim(this, mN, 10)');
 pMenu.hideMenu = new Function('mN','menuAnim(this, mN, -10)');

 // Alternatively: try the IE5.5+/Windows filters. Comment above two lines out and uncomment:
 //pMenu.showMenu = function(mN)
 // { menuFilterShow(this, mN, 'progid:DXImageTransform.Microsoft.fade(duration=1)') }
 // There's a good list of transitions available from http://msdn.microsoft.com

 // Add animation to other menu objects like this...
 //anotherMenu.showMenu = new Function('mN','menuAnim(this, mN, 10)');
 //anotherMenu.hideMenu = new Function('mN','menuAnim(this, mN, -10)');
}


// Advanced (or just plain determined to tweak everything) users: Custom item arrangement!
// Here you can extend a menu's overall dimensions, and then reposition or resize its items.
// You can arrange the items however you want within a menu, in a curve or similar,
// or even change the overall arrangement of the menu (put items in rows etc).
// Individual items have .iX and .iY which are positions and .iW and .iH which are dimensions.
// I recommend doing this *before* calling the border or shadow commands too :).

//with (pMenu.menu)
//{
// mFile[0].menuW += 20;
// mFile[0].menuH += 20;
// mFile[1].iX += 5;
// mFile[2].iX += 2;
// mFile[2].iW -= 2;
// mFile[3].iX += 5;
// mFile[4].iX += 10;
// mFile[4].iW += 10;
// mFile[4].iY += 3;
//}







// *** (4) EVENTS ***
//
// In JavaScript, there are document 'events' you need to set so any scripts you are using
// are notified of things like page loading/clicking/scrolling. If you've got several menus
// or another JavaScript entirely in your page, you'll need to add all their functions in here.
// For another menu object, call its functions like update() and position() next to pMenu's,
// I've put examples in to show where these need to go.
//    The reason for these is that every time you set them, they override a previous setting.
// So make sure you collate all the functions that need to be called in here! Syntax:

//object.onevent = function()
//{
// function1();
// function2();
// ...
//}

// That's similar to: <BODY ONEVENT="function1(); function2(); ...">


// The most important event is one used to display the menu by calling one of several methods of
// any menu object(s) you have created. This is where you select the menu creation mode. 'Dynamic'
// mode inserts the menus into the document once it has finished loading and supports features
// like modifying the menu after creation. You update a menu in 'Dynamic' mode by just calling the
// .update() method of a menu object like 'pMenu'.
//    'Fast' creation mode writes the menus to the document here and now, which is faster and
// more reliable in many browsers but only when the document's loading -- you do this by passing
// 'true' without quotes to the update function to signal that we're inline.
//    Opera only supports Fast mode and Netscape 4 only supports in Dynamic mode, so we use
// browser-detect code here. If you find some browser has troubles with one mode or another, try
// the other menu creation method -- see the "Cross-Browser" code at the very top of the SCRIPT
// tag for the variables used.
//    Hardcore tweakers -- there's some extra code commented in the popOver() function at the top
// which lets you create the root menu on page load and other menus only as needed, which might
// be useful for very very large menus in a single frame. Look it up if you want.

if (!isNS4)
{
 // Write menus now in non-NS4 browsers, by calling the "Fast" mode .update(true) method.
 pMenu.update(true);
 //anotherMenu.update(true);
}
else
{
 // For Netscape 4, back up the old onload function and make a new one to update our menus.
 // This is the regular "Dynamic" mode menu update, it works in IE and NS6 too if required.
 var popOldOL = window.onload;
 window.onload = function()
 {
  if (popOldOL) popOldOL();
  pMenu.update();
  //anotherMenu.update();
 }
}


// Other events must be assigned, these are less complicated, just add or remove menu objects.

var nsWinW = window.innerWidth, nsWinH = window.innerHeight, popOldOR = window.onresize;
window.onresize = function()
{
 if (popOldOR) popOldOR();
 if (isNS4 && (nsWinW!=innerWidth || nsWinH!=innerHeight)) history.go(0);
 pMenu.position();
 //anotherMenu.position();
}

window.onscroll = function()
{
 pMenu.position();
 //anotherMenu.position();
}


// NS4 can't reliably capture clicks on layers, so here's a workaround.
if (isNS4)
{
 document.captureEvents(Event.CLICK);
 document.onclick = function(evt)
 {
  with (pMenu) if (overI) click(overM, overI);
  //with (anotherMenu) if (overI) click(overM, overI);
  return document.routeEvent(evt);
 }
}

// Activate the window.onscroll() event in non-Microsoft browsers.
if (!isIE || isOp)
{
 var nsPX=pageXOffset, nsPY=pageYOffset;
 setInterval('if (nsPX!=pageXOffset || nsPY!=pageYOffset) ' +
 '{ nsPX=pageXOffset; nsPY=pageYOffset; window.onscroll() }', 50);
}






// *** (5) OPTIONAL CODE ***   DELETE IF YOU'RE NOT USING THESE!


// MOUSE EVENTS:
//
// If you want, you can assign functions to handle mouse events like mouse over/out/click.
// You'll want to use these for assigning click actions to 'sm:' items or status messages etc.

// However you can override this behaviour with custom show/hide animation routines,
// as we have done in the "Menu Effects" section. Feel free to edit this, or delete
// this entire function if you're not using it. Basically, make functions to handle
// menuObj.showMenu() and .hideMenu(), both of which are passed menu names.
//
// Customisers: My lyr.clip() command gets passed the parameters (x1, y1, x2, y2)
// so you might want to adjust the direction etc. Oh, and I'm adding 2 to the dimensions
// to be safe due to different box models in some browsers.
// Another idea: add some if/thens to test for specific menu names...?

// *** (6) FRAMESET README ***

// You're looking at the single-frame version of this script right now. This menu does support
// frames with a few extensions -- the core script is the same, but you need to remove the "Events"
// section and include a modified version of it in each loaded file. Get the frameset example from
// my site first, I've put the modified section in a file named "SUBFR.JS".
//
// This script should reside in the topmost frameset. Files loaded in this frameset must satisfy
// two conditions to work:
// 
// 1) They must have all the needed CSS info from the <STYLE> tag included in them, and a small
// JavaScript file (SUBFR.JS) to activate and manage the menus in that frame.
// 
// 2) They must be from the same domain as this frameset -- you can't load in search results or
// similar from another server and pop menus out over it, due to browser JS security rules.
// 
// With the SUBFR.JS file, all you have to do is make sure that in the first line pMenu points to
// the correct pMenu -- that is, located within that frame's parent (this script). If you're using
// multiple menu objects across frames or loading framesets within framesets, you will have to edit
// it, otherwise just leave it as is. To use multiple menus, you need to create them both here and
// then edit SUBFR.JS in the same fashion as the Events section here, calling your second menu
// object whenever pMenu itself is called.
// 
// The example setup allows the menus in sub-frames scroll with their windows. All you have to do is
// use the 'page' object in that frame in a formula to get the current scrolling position of that
// frame, and then add or subtract pixels to position the menus from the scroll position, e.g. for a
// menu in a frame named 'xyz', we would set it to appear in that frame and appear near the top and
// 100px from the left:
// 
// startMenu('menuName', false, 'xyz.page.scrollX()+100', 'xyz.page.scrollY()+10', 17, hBar, 'xyz');
// 
// Of course, third-level menus in other frames can be positioned relative to their parents
// normally. (Remember: strings as positions mean 'absolute' and are calculated as formulae,
// numbers as positions mean 'relative', offset from its parent).
// 
// JS window syntax is OK, so parents can be 'xyz.subFrame.something' if you want, and the SUBFR
// file in that frame/window points back to this one (try scrWin=top rather than scrWin=parent).
// You'll probably want to specify target frames for each menu item, in the same fashion as
// you specified them for the menus themselves -- by default URLs will open in the window in
// which the script is located, the topmost frameset. Try addItem('Text', 'file.html', 'botFr');
