I have set CollapsibleSubtrees = true, which seems to automatically use the +/- decorators on my tree.
The question is, how do I globally change the decorator?
The examples suggest I have to iterate through every shape, and create a new decorator for each one.
Surely there must be a simple way to set the decorator for all shapes without doing this?
Where is the setting for the global +/- decorator currently being used?
Thanks
