Saving the scroll position in a scrolling list field

[glenn9]

Hi,

I've got a scrollling list field of items on Card A which when an item is tapped, navigates to a linked different card, ie a simple notes app.

As the scrolling list field now contains over a 100 items I was wanting to see if I could code returning to the same item, ie the same position in the scrolling list field, that was tapped when navigating back to card A from another card.

I was hoping the 'thumbposition' command might help but on checking the dictionary and despite this with some trial error, I don't think this is the correct command as I can't seem to put the 'thumbposition' into a variable that I can then reference, to return to a particular position in card A.

It might not even be possible but I just wanted to check!

Many thanks,

Glenn

Hi Glenn

I think you might be looking for the vScroll property, rather than the thumbposition.

I hope that helps.

I would have thought the best idea would be to SAVE the stack just before it navigates to the new card, thereby
preserving the scrollBar at the position it is before going to the new card.

Here's the code in my scrolling list field:

Code: Select all

on mouseUp
   save stack "SHUFFLE"
   put the selectedLine of me into ZZZ
   set the itemDelimiter to " "
   put item 2 of ZZZ into XXX
   put line XXX of fld "scf" into KARD
   go to card KARD
end mouseUp

Thanks Elanor, that works perfectly!

I've used on card A:

Code: Select all

put the vScroll of field 1 into gScrollPosition

and on card B:

Code: Select all

set the vScroll of field 1 of card A to gScrollPosition

I never ceased to be amazed at how straightforward LC can be, especially for me as a beginner!

Kind regards,

Glenn

Hi Richmond,

Thanks for the stack, I'll put your solution into my toolbox as well...

Saving the stack is of course no option in a runtime!

Saving the stack is of course no option in a runtime!

Unless your using the standalone as a launcher for your program stacks...

Where do you live again?

Probably somewhere near the bag end of Lake Michigan, I imagine.
