Dear Rooters
I have the following strange problem and do not know how
to find the error:
I have a basic library and a couple of derived libraries,
which define different XManager classes and subclasses.
Using one of the derived libraries I am able to execute
the following macro from within ROOT:
void Normalize(
{
XNormationManager *manager = new XNormationManager("Manager");
manager->Initialize("PixType");
manager->InitSelector("rank", "separate", 4,0,0.3,400,0);
// here I initialize XSelector::fOption = "separate"
manager->New("test","~/ROOT/rootcode","PixType");
// here I create file = new TFile(name,"CREATE", title)
manager->OpenData("~/ROOT/rootdata/test.root");
manager->Select("TestSet","tree1");
// at this point XSelector::fOption is already set to:
// fOption = "CREATE" instead of fOption = "separate"
// when this code is part of a standalone GUI app!
manager->Select("TestSet","tree2");
manager->Select("TestSet","tree3");
manager->Normalize("TestSet");
delete manager;
}
Please note that this macro has always worked witout any
problems and still runs perfectly fine.
However, now I have developed a GUI application, where
the user can set all parameters graphically, and where
this code is implemented within different methods of
my class XNormationFrame. In the XMainFrame I have defined:
static XNormationManager *sNormManager;
and the subframe calls e.g.
XMainFrame::sNormManager->Initialize("PixType")
etc.
When I press the button to execute the same commands
as in my macro, then XSelector::fOption, which is
set to "separate" in InitSelector(), is strangley
set to "CREATE" after execution of manager->New()!!
I know that you cannot give me a concrete answer, but
maybe you could tell me:
Does this look like a buffer overflow?
What are the usual errors which result in such an error?
What can be done to track down this error?
Thank you in advance
Best regards
Christian
