If a canvas with an 1028 // identical name exists already in this list, the canvas is 1029 // deleted. In normal operation this might make sense and doesn't harm 1030 // because the embedded canvases behave different. 1031 // By creating the canvas without a name it is made sure that no 1032 // older canvas/tab vanished silently from the system (deleted from 1033 // the construtor). To make the handling of our canvases nevertheless 1034 // work well the name is set later. The list of canvases is also 1035 // part of the list of cleanups, thus fBatch need not to be added 1036 // to the list of cleanups. 1037 TCanvas *c = new TCanvas("", name, -cw, ch); 1038 c->SetName(name); 1029 1039 fBatch->Add(c); 1030 1040 return *c;
