The user interface for a card I'm writing dynamically arranges various buttons on the card. Thus, a button may be anywhere on the card when it is pressed. A button unhides an associated field. I want the field to appear below the button. That's the part that has me stumped. If the button script could learn the identity of the button that has it, this would be easy. I could then get the position of the button. I could even write the code for displaying the field in the card instead of duplicating it in each button, thus saving a lot of code duplication. Is there some means for a script to learn the identify of its holder button, field, card, whatever? Is there another approach I have not considered? I'd be grateful for either HC1 or HC2 ideas. -- peace. -- Ed "Over here, Bones! This man's dying!" "Damn it, Jim! I'm a doctor, not a . . . What did you say?"

When the user clicks on an object (Button, Field, Card), the
container "target" contains the identification of that object.
The script you want to use would look something like this:
on mouseUp
set the top of cd fld 1 to the bottom of the target
set the left of cd fld 1 to the left of the target
end mouseUp
This is just a very rough script. If you need more assistance,
please don't hesitate to ask.

P.S. As always, the documentation is many times the most
definitive source for HyperTalk languauge definitions.
Note that there is some discussion to be found in the
documentation which outlines the somewhat esoteric
differences between "the target" and "target".jkc@Apple.COM (John Kevin Calhoun) (01/19/91)

Yes. You can, for example, get 'the rect of me', to get the position of a button whose script is executing. Kevin Calhoun HyperCard Team Apple Computer, Inc.
