Re: wxTreeCtrl InsertItem Method

Steve:

InsertItemBef works.

I couldn't find a method that returns an item's position under a node, so I
wrote a sub to loop through all the children of a node and calculate the
index(get_item_index). Surprised this function wasn't in wxWidgets.

AppendItem is also useful as it has two behaviours.
   1. Appending to a node adds a new item to the node in the last position.
   2. Appending to a leaf, creates a new item in a level below the leaf.

I agree that it's better if the implementation matches the wxWidgets docs
since that's all we have.

I've read the XS stuff on the wiki and I don't know enough to understand it
yet.

Thanks for the help.

James
