Hi, all! Can any one out there tell me how can dim a text string? I am developing a stack with many buttons. I like to set the textStyle to "dimmed", so that it is disabled but people can still see it. Any suggestions? Thank you in advance. --Tony Lim

In HC 1.2, I painted text onto the card graphics behind buttons I wanted to disable & dimmed them manually. When I wanted to disable a button, I just used the "hide cd button foo" command. It worked wonderfully, but it was a pain to move the background bits around if the buttons needed to be repositioned. HC 2.0 might have better disable tools, but I haven't had much time to take a look at it yet. -- ___\ /___ Greg Anderson (6 kyu) ___\ /___ . O .

Here is a script which paints a dimmed image of a button beneath that button. It works for both card and bkgnd buttons. Not for icons, though!

In principle, there is a simple and nice way to dim text: provide a
"dim" font, and switch to and from it as needed. Here's some notes on
doing that.
First, you have to make a dim font. I have seen a font "ChicagoGrey"
floating around, but I don't know its legal status. Nevertheless, you
could use any font editor to make one of your own, and install it into
whichever stacks need it. The details of this are left as an excercise
to the Reader.
Second, although the Hypertalk statement "set the textfont of <blah>
to <foo>" works fine, it can actually be very slow, for reasons only
the HC team understands. Therefore, here are three suggestions:
* If you are going to update a "button panel" frequently, consider
wrapping a "lock screen" and an "unlock screen" around the whole mess.
It will speed things up quite a bit.
* Use something like the following to change the button status:
on setEnabled oname status
if (the textfont of oname is "Chicago") is status then return
else
if status
then set the textfont of oname to "Chicago"
else set the textfont of oname to "ChicagoGrey"
end if
end setEnabled
The first line checks to see if the object has the right font already,
and if so exits without doing anything. This hack also greatly
increases the speed of updates.
* Don't update the status of any buttons that "obviously" should not
have changed. Don't hurt yourself doing this, though. I once figured
I'd optimize the updates through the World's Most Complex If
Statement, but it didn't help. ALL of the slowness came from the "set
textfont" statement.
By following these precautions, you will have speedy updates.
Last, you need this handler in your buttons:
on mouseDown
if the textfont of this button is "Chicago" then...
end mouseDown
Embellishments optional. Tartar sauce 35 cents extra.
If you need more help, drop me a line.

Apple recommends that you don't include fonts in any documents. And since a stack is just a document Apple recommends not putting them into a stack either. I believe it has something to do with the print monitor. I thought that you might like to know.
