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.

CalendarPopup.js

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.

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.

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.
