I'm trying to set up a global text only library that includes text handlers for
formatting text run time.
Typical use case is : clickable list field with titles that wrap. Say you set
type size to 16, text height to 20, dontWrap is false, first indent -40, left
margin 20. This looks fine, but the lines are too close together.. Since there
is no way to apply "spaceBelow" to a field…you have to dynamically run a script
to "set the type" of each line run time after loading the field.
So far so good until this
# card script
put tTitles into fld "audioList" # contains 30 lines
addSpaceBelowListLines (the long id of fld "audioList"),10
lib_SivaSivaMedia # a global "backscript" -- one of many
on addSpaceBelowListLines pField,pSpace
put the number of lines of pField
# returns 1 --
# -- of course, that's a prop of the var, not the object it refes to
repeat with x = 1 to (the number of lines of pField)
set the spacebelow of line x of pField to pSpace
end repeat
end addSpaceBelowListLines
# only line 1 gets added space.
In the msg box I can test
put the number of lines of (the long id of fld "audioList")
[return] 30
but
put the number of lines of pField = 1
# ok I get it a var, single string, 1 line only
of course we can add to the card script
put tTitles into fld "audioList"
put the number of lines of tTitles into pLineCount
addSpaceBelowListLines (the long id of fld "audioList"), pLineCount, 10
LIBRARY:
on addSpaceBelowListLines pField, pLineCount, pSpace
repeat with x = 1 to pLineCount
set the spacebelow of line x of pField to pSpace
end repeat
end addSpaceBelowListLines
And this works.. it even has an interesting visual effect as the lines layout
dynamically in front of the users, spreading out top to bottom.
( though I probably should lock and unlock the screen for small devices speed)
But that it would be nice not be "stuck" with only finding out the properties
of the variable as a variable.
i.e. pField is a variable with 1 line…
but to be able to address the properties of the object referred to by a
variable containing the long ID of an object/
How do we do that?
