Hi Alexander,
no QtRoot required. It's standard ROOT.
I attached macro which allows to do more funny things
while browsing.
- set "colz" option for TH2 histogram
- zoom TH2 histogram
- it works OK with histograms located in ROOT files
To test it:
- load it
root[].L tst.C
- make class signal-slot connection
root[] TQObject::Connect("TRootBrowser","DoubleClicked(TObject*)",0,0,"Zoom(TObject*)");
- run ROOT browser and browse hsimple.root file from tutorials directory.
- double click on hpxy histogram
I would like to add that using "class signal-slot " connections is
equivalent to overloading class method without recompiling.
Regards. Valeriy
