IsItemExpanded #172

Closed MobileMon closed 8 years ago

MobileMon commented 8 years ago

How can I tell if an item is expanded

I use treeView.isCellExpanded but the problem is it only lets me know after the animation for expansion is complete. I need to know before the animation is complete so I can show different states of an open close button (+, -)

Why not do that before you expand the item? You know which item will be expanded when the users taps; or during the initial render.

Hmm ok I guess that works. I can just store the state on the data object and set it in willSelectRowForItem, reload that item, then continue with didselectitem

A little laborious to do this work but it works. Still feel like the treeview should be responsible for this
