What is the benfit of disabling tree selection?
The same as disabling a menu item in a menu? Think about <tree>'s that look like something <completely different>.
How will this effect keyboard navigation?
That should work just like disabled menu items.
It sounds like you present some options/actions for the selected item in a tree, why not just disable these actions.
Yes, but it should work like a disabled menu item, because that is what I want.
e.g. you can select this item, but then all of the buttons/menus become disabled. Then you could add an arbitrary attribute to the item and test for that (and perhaps add a different decorator/css style).
Yes, I could do that, but that is not what I want.
Maybe take a step back and describe the GUI behaviour you want (provide functionality X for some subset of a tree of objects) rather than your proposed solution (disable some of the elements in the tree).
The tree could also be a menu, or listbox, driven by that data source. All I want is to disable some items, for whatever reason, but without messing with the data source and/or adding properties.
