//
// Now you've created a basic menu object, you can add optional effects like borders and
// shadows to specific menus. You can remove this section entirely if you want, the
// functions called are found at the bottom of this file.



// BORDER: Added to all menus in a named object 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 solid colour (just like the ItemStyles).

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



// DROPSHADOW: added to specific ItemStyles 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 to make it solid), 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]);



// ANIMATION SETTING: We add this to the 'pMenu' menu object for supported browsers.
// IE4/Mac and Opera 5/6 don't support clipping, and Mozilla versions prior to 1.x (such as
// Netscape 6) are too slow to support it, so I'm doing some browser sniffing.
// 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 (defaults are 10 and 15).

if ((navigator.userAgent.indexOf('rv:0.')==-1) &&
    !(isOp&&!document.documentElement) && !(isIE4&&!window.external))
{
 pMenu.showMenu = new Function('mN','menuAnim(this, mN, 10)');

 //anotherMenu.showMenu = new Function('mN','menuAnim(this, mN, 10)');
 //anotherMenu.hideMenu = new Function('mN','menuAnim(this, mN, -15)');
}







// ******************** FUNCTIONS CALLED BY THE EFFECTS SECTION ********************

// These can be deleted if you're not using them. Alternatively, if you're using several menu
// data files, you may want to move them to the "core" script file instead.

// Animation:
//
// Each menu object you create by default shows and hides its menus instantaneously.
// 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.showAnim() and .hideAnim(), 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...?

// is written to the document with the menus as they are created -- the string can contain
// anything you want, really. They also adjust the menu dimensions and item positions
// to suit. Dig out the Object Browser script and open up "pMenu" for more info.
