Removing individual TreeItems from a Tree [message #454174]

I see that support has been added in 3.1M6 for indexing TreeItems:

Tree supports indices
New API has been added so that items in a Tree can be referenced by index.
The index is relative to the immediate parent which for top level nodes is
the Tree and for sub-nodes is the parent TreeItem. The new API includes
Tree/TreeItem.indexOf(TreeItem) and Tree/TreeItem.getItem(index). In
addition, you can remove the children of a tree item using
TreeItem.removeAll().

Does anyone know if there are plans to add remove(index) to remove a single
TreeItem? Or is this accomplished through something like
TreeItem.dispose()?

Thanks,
Greg

dispose() is correct and available now so I don't think they'll be
adding a remove(index).

It's possible that the API will be removed for 3.1. Sorry, that's all I can
say right now.
