Hi Rooters,
I have observed a very stange behaviour in TNode (I am sure that I am
guilty!!!).
I have defined a class, ANTLcm, where a volume is defined and placed
inside a mother volume (code below). In the main program I have defined
a main volume called mother where an ANTLcm menber is placed.
When I check that everything is Ok by doing a mainnode->ls(), my
ANTLcm
menber is correctly placed inside the main volume. However when I try to
pick the ANTLcm menber with the mouse, it doesn't work. Moreover I have
observed with the ROOT event status that this member is detected at the
center of the main volume. Does somebody have an idea of the problem?
Thank you very much,
Stephane BASA
