<h1 align="center">XeoMenu 1.1</h1>
<p align="center">by Patrick Chan</p>
The XeoMenu applet takes an image and allows you to
overlay menus on the image. You define <em>hotbox</em> areas on
the image and when the user rolls the cursor into a hotbox, two
things happen - first, the sub-image in the hotbox changes
appearance and second, a menu of menu items appears. </p>
<h3>Menus and Menu Items</h3>
<p>Here is a screenshot of the XeoMenu in action. The cursor was
moved into the hotbox labeled "Where Can I Read
About...!" which causes the hotbox to change (the copy
becomes italics) and a menu of eight menu items to appear. In the
screenshot, the cursor is currently over the menu item labeled
"Tutorial" which causes the menu item to highlight. If
the user now clicks on the menu item, the browser would go to the
HTML page that describes the Online Java Tutorial.</p>
<p>Since the XeoMenu applet was built to Javasoft's
specifications, the menus are not as general as you would like.
In particular, the menu always appears to the right of the
hotbox. Also, the labels of the menu items are always right
justified. Finally, there is always an outline around each menu
item. This applet might be extended someday to allow for more
general layout but for now, you will have to modify the code if
you want a different menu layout.</p>

<h3>The Parameters</h3>

parameters must be specified, even if they will not be used.</p>
