identifying text members via lingo.

[Richie Bisset]

i have a movie with several scrollable text members. For each of these
i want to set the scroll top so that they are automatically displayed
at the top of the text.

obviously i can do this individually, but i was wondering if there
were some way, within the start movie handler, to list all the members
in the movie, determine which are text and then set the scroll top
value from there.

any help would be appreciated.

regards,

richie

thanks luk,

can i ask two more questions though. Firstly, i should know how to do
this but how do you loop through the members with lingo? tehre is no
member list property or anything like that i'm aware of.

secondly, as far as i can see in the LD there is no support for #text
with the ilk command, so how would i detect the type anyway.

thanks for your help.

nCasts=the number of castLibs
repeat with c=1 to nCasts
n=the number of members of castLib c
repeat with mem=1 to n
if the type of member(mem, c)=#text then
-- whatever
end if
end repeat
end repeat

Thanks to both of you. That is perfect. I really shoulf have known
that.

What is the distinction between ilk and type though? i'd just been
trying to use ilk up to this point.

cheers,

on resetTextMembers
thisManyCasts = the number of castLibs
repeat with i = 1 to thisManyCasts
thisManyMembers = the number of members of castLib i
repeat with j = 1 to thisManyMembers
if member(j,i).type = #text or member(j,i).type = #field then
member(j,i).scrollTop = 0
end if
end repeat
end repeat
end


To speed up the process:
1. if you segregate all of your text and field members into one cast
then you only have to loop through that one cast.

2. if you only use text members or only field members then you don't
have to test for the other member type.

thanks rob,

Andrew Morton had already supplied some code, but thanks for the
optimisation tips.

I had stuck to text members anyway, i generally only use fields for
editable text anyway. I've now moved all of them into one cast and i'm
only checking that cast.

thanks again,

richie
