Hi David, here some answers to your questions. 1) Full screen size: Int_t x, y; UInt_t w, h; gVirtualX->GetWindowSize(gClient->GetRoot()->GetId(),x,y,w,h); 2 & 3) Input from console and using Getline (with tab expansion and command line editing). See attached macro term3.C. 4) Rene will answer this. Cheers, Fons.
