thank you for an answer. I'm afraid I wasn't specific
enough. Your advice applies to user defined classes
derived from ROOT classes, where I can override
DistancetoPrimitive fucntion. Actually I've been doing
this quite successfully hiding my objects from being
seen by mouse.
What I really wanted - to be able to switch off/on
this ability for ROOT native objects. Now (or untill
I was bored to do so and asked this question) I create
dublicates of ROOT classes (derived from ROOT that is)
wich differ from originals only by the definition of
DistancetoPrimitive. I found it a bit tedious and
sought an expert opinion.
Good if next ROOT version would have this switch
programmed in.
thank you very much,
Dmitri
