AnchorPosition.js
Author: Matt Kruse
Last modified: 10/11/02

DESCRIPTION: These functions find the position of an <A> tag in a document,
so other elements can be positioned relative to it.

COMPATABILITY: Netscape 4.x,6.x,Mozilla, IE 5.x,6.x on Windows. Some small
positioning errors - usually with Window positioning - occur on the 
Macintosh platform.

FUNCTIONS:
getAnchorPosition(anchorname)
  Returns an Object() having .x and .y properties of the pixel coordinates
  of the upper-left corner of the anchor. Position is relative to the PAGE.

getAnchorWindowPosition(anchorname)
  Returns an Object() having .x and .y properties of the pixel coordinates
  of the upper-left corner of the anchor, relative to the WHOLE SCREEN.

NOTES:

1) For popping up separate browser windows, use getAnchorWindowPosition. 
   Otherwise, use getAnchorPosition

2) Your anchor tag MUST contain both NAME and ID attributes which are the 
   same. For example:
   <A NAME="test" ID="test"> </A>

3) There must be at least a space between <A> </A> for IE5.5 to see the 
   anchor tag correctly. Do not do <A></A> with no space.

PopupWindow.js
Author: Matt Kruse
Last modified: 3/21/02

DESCRIPTION: This object allows you to easily and quickly popup a window
in a certain place. The window can either be a DIV or a separate browser
window.

COMPATABILITY: Works with Netscape 4.x, 6.x, IE 5.x on Windows. Some small
positioning errors - usually with Window positioning - occur on the 
Macintosh platform. Due to bugs in Netscape 4.x, populating the popup 
window with <STYLE> tags may cause errors.

USAGE:
// Create an object for a WINDOW popup
var win = new PopupWindow(); 

// Create an object for a DIV window using the DIV named 'mydiv'
var win = new PopupWindow('mydiv'); 

// Set the window to automatically hide itself when the user clicks 
// anywhere else on the page except the popup
win.autoHide(); 

// Show the window relative to the anchor name passed in
win.showPopup(anchorname);

// Hide the popup
win.hidePopup();

// Set the size of the popup window (only applies to WINDOW popups
win.setSize(width,height);

// Populate the contents of the popup window that will be shown. If you 
// change the contents while it is displayed, you will need to refresh()
win.populate(string);

// Refresh the contents of the popup
win.refresh();

// Specify how many pixels to the right of the anchor the popup will appear
win.offsetX = 50;

// Specify how many pixels below the anchor the popup will appear
win.offsetY = 100;

NOTES:
1) Requires the functions in AnchorPosition.js

2) Your anchor tag MUST contain both NAME and ID attributes which are the 
   same. For example:
   <A NAME="test" ID="test"> </A>

3) There must be at least a space between <A> </A> for IE5.5 to see the 
   anchor tag correctly. Do not do <A></A> with no space.

4) When a PopupWindow object is created, a handler for 'onmouseup' is
   attached to any event handler you may have already defined. Do NOT define
   an event handler for 'onmouseup' after you define a PopupWindow object or
   the autoHide() will not work correctly.

CalendarPopup.js
Author: Matt Kruse
Last modified: 3/21/02

DESCRIPTION: This object implements a popup calendar to allow the user to
select a date, month, quarter, or year.

COMPATABILITY: Works with Netscape 4.x, 6.x, IE 5.x on Windows. Some small
positioning errors - usually with Window positioning - occur on the 
Macintosh platform.
The calendar can be modified to work for any location in the world by 
changing which weekday is displayed as the first column, changing the month
names, and changing the column headers for each day.

USAGE:
// Create a new CalendarPopup object of type WINDOW
var cal = new CalendarPopup(); 

// Create a new CalendarPopup object of type DIV using the DIV named 'mydiv'
var cal = new CalendarPopup('mydiv'); 

// Easy method to link the popup calendar with an input box. 
cal.select(inputObject, anchorname, dateFormat);
// This is an example call to the popup calendar from a link to populate an 
// input box. Note that to use this, date.js must also be included!!
<A HREF="#" onClick="cal.select(document.forms[0].date,'anchorname','MM/dd/yyyy'); return false;">Select</A>

// Set the type of date select to be used. By default it is 'date'.
cal.setDisplayType(type);

// When a date, month, quarter, or year is clicked, a function is called and
// passed the details. You must write this function, and tell the calendar
// popup what the function name is.
// Function to be called for 'date' select receives y, m, d
cal.setReturnFunction(functionname);
// Function to be called for 'month' select receives y, m
cal.setReturnMonthFunction(functionname);
// Function to be called for 'quarter' select receives y, q
cal.setReturnQuarterFunction(functionname);
// Function to be called for 'year' select receives y
cal.setReturnYearFunction(functionname);

// Show the calendar relative to a given anchor
cal.showCalendar(anchorname);
cal.showCalendarWithParam(returnParam, anchorname);

// Hide the calendar. The calendar is set to autoHide automatically
cal.hideCalendar();

// Set the month names to be used. Default are English month names
cal.setMonthNames("January","February","March",...);

// Set the month abbreviations to be used. Default are English month abbreviations
cal.setMonthAbbreviations("Jan","Feb","Mar",...);

// Set the text to be used above each day column. The days start with 
// sunday regardless of the value of WeekStartDay
cal.setDayHeaders("S","M","T",...);

// Set the day for the first column in the calendar grid. By default this
// is Sunday (0) but it may be changed to fit the conventions of other
// countries.
cal.setWeekStartDay(1); // week is Monday - Saturday

// Set the weekdays which should be disabled in the 'date' select popup. You can
// then allow someone to only select week end dates, or Tuedays, for example
cal.setDisabledWeekDays(0,1); // To disable selecting the 1st or 2nd days of the week

// When the 'year' select is displayed, set the number of years back from the 
// current year to start listing years. Default is 2.
cal.setYearSelectStartOffset(2);

// Set the minimum date Accessible
cal.setMinimumDate(date);

// Set the maximum date Accessible
cal.setMaximumDate(date);

// Text for the word "Today" appearing on the calendar
cal.setTodayText("Today");

// Text for the word "Close" appearing on the calendar
cal.setCloseText("Close");

// Set the calendar offset to be different than the default. By default it
// will appear just below and to the right of the anchorname. So if you have
// a text box where the date will go and and anchor immediately after the
// text box, the calendar will display immediately under the text box.
cal.offsetX = 20;
cal.offsetY = 20;

NOTES:
1) Requires the functions in AnchorPosition.js and PopupWindow.js

2) Your anchor tag MUST contain both NAME and ID attributes which are the 
   same. For example:
   <A NAME="test" ID="test"> </A>

3) There must be at least a space between <A> </A> for IE5.5 to see the 
   anchor tag correctly. Do not do <A></A> with no space.

4) When a CalendarPopup object is created, a handler for 'onmouseup' is
   attached to any event handler you may have already defined. Do NOT define
   an event handler for 'onmouseup' after you define a CalendarPopup object 
   or the autoHide() will not work correctly.
   
5) The calendar display uses "graypixel.gif" which is a 1x1 gray pixel of
   color #C0C0C0. If this file is not present, the calendar display should 
   still be fine but will not show the gray lines.
   
6) The calendar popup display uses style sheets to make it look nice.
