Hi James,
It looks a bit complicated. I'm not a user of TreeCtrl.

Good Day All:
I'd like to use the wxTreeCtrl InsertItem method.
1. I tried calling it and got a loading error which unfortunately I
didn't copy down the exact wording. Is this method wrapped?
It looks half wrapped. I think someone started but didn't get around to
finishing it. It uses an overloaded method in C++, which is a bit more
complex to wrap than normal.
If you look at the two methods (InsertItem
<http://docs.wxwidgets.org/trunk/classwx_tree_ctrl.html#a06e1e6b25a7121922412eea510bd3109>),
it looks to me as though the second would be the most intuitive.
"Insert" normally means insert before. In that case it might not be too
hard to complete that wrapping only and avoid the overload situation.
They could even have two names InsertItemBefore InsertItemAfter.
However the documentation would be inconsistent.
I think the correct answer for now, where nothing works, is to wrap one.
2. Also, to insert an Item, you need an empty Item to insert.
It looks like it just accepts a string, but as I said, I think the
wrapping is incomplete.
I found wxTreeItemId in wxCore, but the comment says it's not intended
to be constructed explicitly by the user. How should you make an empty
Item?
As above, I don't think you need to.
AppendItem works as advertised, but the node is appended after the
last child node which is not exactly what I'd like to do. It could be
dragged where needed, but that adds another step.
According to the doc, Append should append to the last child of the
parent node that you specify. Prepend inserts before the first child of
the specified parent node.
If it doesn't then maybe it's a wxWidgets fault.
Ideas?
Thanks,
James
