Hi All,
Isn't it funny how sometimes one needs to stop thinking about a
design issue in order to receive the inspiration to solve it?
For years as I've used my HyperCard ClickClock and recently as I
converted it to Run Rev, I've been nagged by its lack of
interactivity. It's hard to place twelve discreet hot spots on a
clock face the size of a Mac icon and have the user hit the right
spot every time.
Yesterday, after posting the Library update notice, I thought "well,
that puppy has been put to rest for the foreseeable future." And I
left to see how the world beyond my office had changed in the several
days since I went out in it.
I don't think it was more than two hours of looking at Mendocino &
Lake (California) counties turning green after the first rain since
April before I was aware of the nag...there must be a way to enhance
ClickClock interactivity:
Replace hot spots with buttons?
Make hot spots transparent and change their color when the mouse enters/leaves?
Create a custom cursor set and change cursors when the mouse
enters/leaves a hot spot?
And then, EUREKA!: Change the current frame to the one that would be
selected if the user clicked the mouse at that moment. A few changes
to existing handlers, plus a mouseWithin handler, and the user can
see the clock hand track the mouse as it moves within the image.
So the file bundles at http://www.oenolog.com/ftp/serendipity_downloader.htm
and ClickClock.rev.sgz have been updated with a new version that does
just that.
I labeled this the penultimate touch because ideally the image should
be resizeable and scripted so the hotspots are recalculated when the
image is resized as well as when it is moved.
I also changed handlers so the clickClockTime message is sent to the
image itself, which passes it up the message chain. The original
version sent the message to the card, which meant a clickClockTime
handler could not reside in a group that included the image.
And while I was at it I eliminated a couple of nags in SDB Utilities:
* Compress, expand, and convert file menuPicks now offer the user the
option to process another file rather than forcing the user to select
the menuItem once for each file processed.
* Compress, expand, and convert file remember the the paths to the
folders the last file was read from and written to. If the user
processes multiple files, ask/answer file dialogs default to the
previous source or destination folder.
SDB Utilities.rev.sgz and the bundled Library files include this uodate.
Enjoy!
