Hi Rooters, A silly question by the end of this day (here in Europe): Any example of application of TCutG to a histogram cause I failed to get profite from the help http://root.cern.ch/root/html/TCutG.html#TCutG:description In addition, if one writes in a macro, SetEditorMode("CutG") ; // the Graphical Cut editor cerr << "Nbr of Pts=" << CUTG->GetN() ; the Nbr of Pts is always 0 because you get to "cerr" command before you set your points on the histogram. Rene, is there any way to access the points clicked with the mouse only when you finish drawing the contour -> in an other way, is it possible to "pause" the exit from the Editor till you finish the contour. Many many Thanks Faouzi -- F. Attallah GSI mbH Planckstr 1 D-64291 Darmstadt Tel: +49 (0)6159 71 2743 Fax: +49 (0)6159 71 2901 Email: F.Attallah@gsi.de
