Hi,
I have just modified a C++ code handling and writing on a root file tens of histograms (a list of TObjArray) into the same code handling and writing the same histograms but now included in canvases. The goal of this change is to handle also TPaveLabels over these histograms.
Vi operation in the source code (cfr. beneath): :1,$s/Add(h)/Add(canvas)
[ul]When I have one TCanvas in the TObjArray; there is no problem. Browsing (TBrowse) the root file containing the TObjArray shows the right lonely canvas.[/ul]
[ul]When I have two TCanvas in the TObjArray; this error appears on the console:
Error in <TCanvasImp::Streamer>: version id <=0 in ClassDef, dummy Streamer() called[list]When I want to browse the root file generated (TBrowse) a strange frame (frame94;1) appear in this root file coming with this console error:
Error in <TCanvasImp::Streamer>: version id <=0 in ClassDef, dummy Streamer() called
Warning in <TClass::TClass>: no dictionary for class TRootContainer is available
[/ul]
[ul]And when I click the frame, some other strange stuffes appears coming with this console error:
*** Break *** segmentation violation
