Hi rooters,

I am trying to get all the objects in a TMapFile. I do the following
to have
the list of objects :

TMapFile *mfile;
mfile = TMapFile::Create("hsimple.map");
mfile->ls();

I can access the object hpx using : hpx = (TH1F *) mfile->Get("hpx",
hpx);

But I would like the object names ONE BY ONE to fill a list in a window
widget.
I take a look on the TMapFile::ls() function (see below), it uses the
TMapRec class
which is only for internal use of TMapFile functions (there is no .h
file corresponding).

TMapRec *mr = GetFirst();
while (OrgAddress(mr))
{
Printf("%-20s %-20s %-10d", mr->GetName(fOffset),
mr->GetClassName(fOffset), mr->fBufSize);
mr = mr->GetNext(fOffset);
}

What can I do ?

Regards,

Alberto
