Oh - you mean you put actual data in it :-)
I didn't get that far - just created a tree control and checked that a 
tooltip then worked.

Won't help.     It's not a bug, it's a feature :-)

At least on Windows, you can set the tooltip individually for each item 
(from the WX docs it does look as though this is Windows only, but I'm 
not in a position to try it on other systems just now).

This isn't exposed through PythonCard, so you need to use the wx event 
system directly. I changed the minimalTree sample as below (changed line 
and section marked in comments). The "OnItemExpanded" isn't needed - but 
it was the one I used for first experiments.  For this example, I just 
always set the same tooltip, but you could customize
