Re: Two Marker Styles and SetMarkerAttributes

The easiest script to illustrate the problem is:

TCanvas c;
TAttMarker m;
m.SetMarkerAttributes();

as a result the a dialog which I can use to change the marker attributes stored in m should appear. I simply need a solution to open this Marker dialog for a standalone TAttMarker.
