Hi Rene,
Thank you for your prompt answer.
This morning, after plotting 1dim or 2dim hist, I tryed as a command-line
TCutG *cutg = (TCutG*)gPad->WaitPrimitive("mycut","CutG") ;
So I could peacefully go back to the graphics, mark the contour-points and
close ths contour by double-clicking the same mouse-button. Despite the fact
that he contour is closed, as I can see on the graphics, I could not access to
the command line anymore-> no return from the WaitPrimitive() function.
I failed also when using :
gROOT->SetEditorMode("CutG") ; gPad->WaitPrimitive() ;
Did I do anything wrong ?
Cheers ,
Faouzi
