Best way to compile and debug standalone Eve/track.C tutorial example

PS: a little update…

I have added the following two lines for (my hope at least) displaying the chosen product track to my scene:

//_end FindTrack

     if(track){
        track->SetRnrSelf(kTRUE);
        cout<< "++ itrk="<<itrk<<endl;
        sb->AddElement(track);          // update scene top track plot
1.         sb->Changed();
2.         sb->Repaint(kTRUE);
        //gEve->GetScenes()->RepaintChangedScenes(kFALSE);
        //gEve->GetScenes()->RepaintAllScenes(kTRUE);
        //gSystem->ProcessEvents();
     }

And it partially works for my first track in the list (small blue track lower middle):

But unless I hover on the Browser list or click on the partially displayed tracks in the frame which forces a “ProcessSceneChanges”, I can’t seem to make it display the rest of the tracks in the list:

Any recommendations on the correct thought process, or proper sequence required to control these rendering behaviors?

Thanks.
