Dear ROOTers,
I need to create many TCanvas objects, use all their functionality and save them to disk. I would rather save histograms, but as a matter of fact I use geometrical shapes like TBoxes and they can’t be associated to histograms.
Since this has to run in a large simulation framework, I can’t afford to have them actually pop up for every single event processed. The code is compiled into libraries and then run using CINT macros which results in exactly this effect: Every call to create a new TCanvas results in a canvas window popping up.
Is there a way to prevent the actual creation in the system’s GUI system?
