[ROOT] customizing TAxis

Hi all,

I would like to customize TAxis so to add a method to the popup menu and
to execute a given function when a zoom (or unzoom) is done. The problem
is that TAxis is owned by a TH1 and I cannot force this TH1 to change
it's axis object for my private version of it.

1) is there a way to add a function to the popup menu without touching
the class ? It seems not, but one never knows. I tried to see if I could
implement it with signal/slot but no way.

2) is it possible that a zoom or unzoom action on a TAxis sends a signal
? It seems not since TAxis does not derive from TQObject

3) can I replace the TAxis used in TH1 with my version which would of
course derive from TAxis ?

Did I miss something obvious ?

Cheers

Damir
