Array controller, data source question

AppleScript
#1

Another problem where I’m stuck.
I have a table (an array controller)
If I select one row in the table I want to retrieve some data of the previous and next “row” of the data source - not the ones displayed in table view.

Any tip where and how to search?
Stay safe!

#2

Off the top of my head: Calculate the indexes and then ask the array controller for arrangedObjects()'s objectAtIndex:theIndex (or objectsAtIndexes: if you want them together).

#3

Many thanks for the swift reply…

I played around with these things - no success so far.
Probably I don’t understand the ‘Index’ things.

How do I calculate the indexes?

#4

Get the array controller’s selectionIndex(), then it’s a case of +1 and -1.

#5

Thanks again.

I still have no success. Don’t know what I’m doing wrong.
I have:

  • subsData
  • subsArrayController
  • subsTableView

The visible rows in the subsTableView might be filtered.
One row is selected.

Now I need the ‘row’ before and after the selected row from the original unfiltered data to retrieve some data from each which should be displayed leaving the table row selected.

#6

Typing off the top:

set theIndex to subsArrayController's selectionIndex()
set preObject to subsArrayController's arrangedObjects()'s objectAtIndex:(theIndex - 1)
set postObject to subsArrayController's arrangedObjects()'s objectAtIndex:(theIndex + 1)

Sorry I missed the reply.
My question was misunderstood and (therfore) I misunderstood the replies as well. And as said before I misunderstood the ‘index’ thing.
I found simple solution but run into a ‘next’ problem and so I put this problem back to the shelf.
