Hi,
A little problem with list sorting:
I'm trying to produce an animation from data reduced from several files.
I can now home in on the data (thanks to David Fanning), isolate the
subsets of interest from each file and produce an MPEG movie. Great!
However, because I simply choose the files in a dialog_pickfile, the
order of the files in the animation is determined by the OS's standard
file sort mechanism (I think). I've considered using a listbox to get
the indicies of the selected filenames in order of the users clicking
and use these values to re-arrange the filenames in the array returned
by dialog_pickfile. I have not delved into widget programming yet
though...
I expect that this may not be too uncommon a thing for people to want to
do, so maybe again there is a solution waiting out there somwhere?
Thanks for any advice,
Andrew

Thank you Marc, this also looks like a good solution to my problem.
With such good advice I've been receiving on IDL topics I feel obliged
to learn something useful so I can help someone else out!
Many thanks for all your help everyone!
Andrew

I have a very simple interactive list sorter. I think it might be just what
you are looking for.
You have to provide an array of strings and the click on two list elements
to swap them.
It returns the sorted inidices. Index your array with it and that's it.
It is derived form another very ancient program I wrote, therefore the
programing style
is not so up to date.
Cheers,
:-) marc

Thank you again David for another solution. I'll be sure to check your
library next time I have a requirement that isn't addressed by the
stock IDL routines.
(The linkedlist program is obviously capable of far more than than I
need for this problem, but If I interpret it correctly it will do the
job fine. I'll hopefully learn a bit more about IDL programming too as
a result :-)
Great!

I have a LinkedList object on my web page that
can be extremely useful for this task. It already
has methods for Adding, Deleting, and Moving
items on the list. I've used it as an image
processing command recorder. But before the
final batch processing of images, the user
has a chance to "edit" the command list, perhaps
by deleting or moving commands around. This
sounds pretty much like what you want to do.
Cheers,
David

Thanks for the advice Pavel. I think that will work fine for the
majority of our situations (ie when the filenames are sensible to start
with). I still need some manual intervention for other cases. I will
try a combination of the two :-)
Thanks again,
Andrew
