Another point:
When you disable a tree (at least using Plastic L&F), the items are grayed in
the same... after installing a custom renderer, this doesn't work anymore...
And if you try to set foreground color "gray" in the custom renderer, nothing
happens until some roundtrip (= reload of tree data)... Also the example ("cyan
leafs") in the api guide I could not get to work satisfactorily...
Kind regards,
