I can't speak for combo boxes, but you can control selection in list
fields when a card opens with "the hilitedLines" property.
on openCard
set the hilitedLines of field 1 to x
end openCard
However, if you want nothing to be selected, you need to explicitly
focus on the field first.
on openCard
focus field 1
set the hilitedLines of field 1 to 0
end openCard
Linking the selection to a local variable (script local) can be
useful for retaining a selection when returning to a card.
local lcHilitedLines
on openCard
focus field 1
set the hilitedlines of field 1 to lcHilitedLines
end openCard
on iChanged
put the hilitedLines of field 1 into lcHilitedLines
end iChanged
Call the "iChanged" handler from a selectionChanged handler in the
field itself. I guess a custom property in the field could be used
instead of a local. This might depend on whether you want the
selection to persist after saving the stack. As the local will always
be empty when the stack loads (assuming it is destroyed on close),
you will start with an empty selection.
As for what should be default behavior, I don't know. Whatever it is,
I'm sure it won't be right for my next project. :)
