 Hi Alexander
it can be done with a trick using signal-slots:
 - create macro (e.g. tst.C) containing the following function:

void SetOpt(TObject* obj)
{
   if (obj->InheritsFrom(TH2::Class())) {
      ((TH2*)obj)->SetOption("colz");
   }
} 

  - load it 
  root[].L tst.C
 - make class signal-slot connection
  root[] TQObject::Connect("TRootBrowser","DoubleClicked(TObject*)",0,0,"SetOpt(TObject*)");

mouse double click in any root browser will invoke SetOpt function

That's all. 

Regards. Valeriy
