The simplest possible GUI

ROOT

Hi,

I’ve read the GUI-creation manual, but I’m looking for a very simple solution: I have a programm which calculates FFT based on some binary input files. I’d like it to plot, at the end of the calculation, a TCanvas with TGraph in it. I’m trying to include TCanvas and TApplication classes in main program, but I cannot make it working. Has someone an example like that?

Cheers,   Mariusz

Hi Mariusz,

See for example $ROOTSYS/test/hworld.cxx
