Earliest example of a rollover in a hypercard application

[Paul L.]

What is the earliest example of a rollover you can think of in a Hypercard
application?

By rollover I mean:

A list of database entries, where moving a highlight or a mouse cursor over
each entry results in some detail data relating to the entry being shown
elsewhere on the display.

I want to know this because there are some software patents which appear to
me to be unfairly granted where I'm sure hypercard applications were
available which predated the patent claims.

I would appreciate any help with this and in fact examples don't have to be
limited to hypercard, though I think hypercard apps are a good likely
source. If you can point to commercially or publicly available software
predating September 1990, fantastic. If you know of any such software
including video - even better. Thought I think hypercard only started to
include video/animation from 1992 (correct me if I'm wrong).

If you know of any such applications I would very much like to hear from
you. I would be grateful if you could also send your reply to
ne...@infinitereason.com as well as this forum but if you would rather not do
so, I will be checking back here regularly.

Thanks

Hi Paul,

I am sure that there are stacks of 15 to 20 years old, which
show information about an object in a field while the mouse
moves over that object. There must be examples of stacks using
the mouseEnter and mouseWithin messages for this purpose.

Two examples are a library stack and a contact database, which I
started to build about 18 years ago. The library stack was
available for download for a while.

The two stacks had so many fields, that I deemed it necessary to
add another field, which displayed information about the object
that the mouse was hovering over. This had nothing to do with
animation, though

The library stack contained a possibility to include pictures
and movies, but hovering over an object was not a way to access
these pictures and movies.

I am sure I have several old stacks, which show some kind of
animation in response to aforementioned messages. If I find
something that does what you are looking for, then I'll post
another message here.

Best,

Mark

I just can't imagine that such a patent would be enforceable.

Thanks Mark

It would be interesting if you find them. To be useful for my purposes it
would have to be demonstrable that they were shown in a public forum. This
is the frustrating thing with the work I'm doing, you can know something was
the case and a patent has been unfairly granted but find you are unable to
prove it.

Just for nostalgia: I checked with Filevision, which is the oldest
application I have, but it doesn't do rollover. BTW it still works on
Tiger/Classic, since 1984.
