FlatNotebook doc:
<http://wxpython.wxcommunity.com/docs/api/wx.lib.flatnotebook.FlatNotebook-class.html#SetSelection>
say:

SetSelection(self, page)
Sets the selection for the given page. The call to this function *generates* the page changing events

I don't now if its a bug in doc or in the code.

About the rule that events should not happen when the thing that generate it is done 
programatically, i don't understand it.
Do you mean that if i put some code on a TreeCtrl EVT_TREE_ITEM_EXPANDED (example) these code must 
only run when the user click, and may not run whe i do TreeCtrl.Expand(item)?
For now it's run. May not run in future versions?
