Re: TColor problem?

Hello Rene,

I added an instance of TStopwatch in the macro. This is the output. I removed some warnings for TCanvas and TH2D.

root [0] .x color.C+
Real time 0:00:02, CP time 0.300
root [1] .x color.C+
Real time 0:00:03, CP time 1.100
root [2] .x color.C+
Real time 0:00:04, CP time 2.550
root [3] .x color.C+
Real time 0:00:06, CP time 4.540
root [4] .x color.C+
Real time 0:00:09, CP time 6.960

I confirmed that this problem happens on both Mac OS X and SL 4.6. I tried 5.25.02 and the current SVN. Configure options for Mac and SL are

$ ./configure macosx

and

$ ./configure --enable-python --enable-pythia6 --with-pythia6-libdir=lib

respectively. Can anyone reproduce this?

Thanks. It works. But actually I know that TPad::cd returns the pointer which should be gPad. I expected that TPad::cd automatically set the gPad to the pointer to the current pad even if I use CINT. This is also explained in the comment of TPad::cd. http://root.cern.ch/root/html/src/TPad.cxx.html#l0kMaE
