You can set the icon of a button to an image ID. But if you want to resize
the button based on the size of the image, you need to find a way to
reference the image. Of course the image could be in the topStack, and this
would be no problem. But if not, the following throws an error.:
set the icon of btn "hello" to 21234
put the formattedheight of image id 21234 into tH
I suspect one can 'walk' all open stacks, and perhaps that's what I'll end
up doing, but was hoping someone had an easier solution-- or the stack
walking code ;-)
Try:
get the long name of img id 21234
or:
get the long name of img id (the icon of btn "hello")
I believe such references only work when the image object referred to is
on the current card.
I don't know of a way to find the long id of an image except by walking
through a list of possible containers....
