Re: wxTreeCtrl InsertItem Method

Hi James,

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

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.

It looks like it just accepts a string, but as I said, I think the 
wrapping is incomplete.

As above, I don't think you need to.

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.
