DisplayIndex as a global variable?

[Crashless]

I'm trying to figure out how to make my Recordings screen expand folders, but be aware if a group is larger than can be displayed, then adjust focus as necessary.

I'm able to use EnsureVisibilityForVariable() to make a variable go to a certain display index in the table, but I have no way of telling what display index the item is at to begin with, so I can't tell if my group is larger than the available spaces in the UI.

Am I missing a simple way of calculating this? I've attached an example of how this would be used.

Thanks!


Edit:
BTW, where can I request that the animation core do a nice table scroll animation when EnsureVisibilityForVariable() has to scroll to view that item?

Edit2:
Realized I should have titled this "DisplayIndex as Predefined Local Variable" sorry for the confusion.

TableRow gives the index of an item in the entire table.

VScrollIndex gives the index of the first displayed item.

TableRow - VScrollIndex gives the index of an item relative to the visible portion of the table on screen.

Ah HA!!!

I knew I was missing something about that stuff, I just couldn't get it to work reliably for some reason before. All seems well now though.

Thanks!
