Hello everyone,
I've created a search field that takes a phrase typed into it and
searches a data field for lines containing the phrase. It works in
the usual way where the search becomes narrower the more you type.
What I haven't been able to do is go backwards, that is, make the
search wider as characters are deleted from the end of the search
string when the delete key is hit. When the delete key is hit,
nothing happens, and I'm not sure how to work a delete key message
into the handler.

Gregory,
I built stack a while back that incorporates this functionality. If
you wan,t you can have a look at it by entering in the message box:
go stack url "http://asay.byu.edu/filterSearch.rev";
This example does more than just filter, hence the longer script. But
it boils down to trapping the rawKeyDown message. The rest of the
scripting does things like tabbing into the filtered list when you
find your term, allowing arrow up and down to change selections in the
list, placing the hilighted line in a field on return, and so forth.
If it's helpful you're welcome to use it.
My second question concerns the format of the field itself and the
Geometry Manager. I jazzed up the field by importing three PNG images
to make it look like Apple's hot dog shaped search field. The two
rounded ends remain fixed in size and maintain their relative
positions while the middle segment is scaled horizontally if the stack
is resized. It all works wonderfully (I believe Eric Chatonet gave me
this tip ages ago --- thanks, Eric) except that whenever the stack is
reopened the middle segment is displayed in its original size
regardless of the size of the stack at the time it was closed. This
means the hot dog appears sliced until the user resizes the stack, at
which time the pieces will snap back together. Any fix for this
little glitch?
Others may have a better solution, but I would try calling resizeStack
on preOpenStack.
