Hello ROOTers,
I've made a very simple controlbar with one button which calls a very
simple macro when you press it .
this is the controlbar-macro :
{
gROOT->LoadMacro("exp.c");
bar = new TControlBar("vertical", "Demos");
bar->AddButton("exp",".x exp.c","alkjdsn");
bar->Show();
gROOT->SaveContext();
}
and this is exp.c :
{ #include <iostream.h>
gROOT.Reset();
Int_t nr;
Int_t nrb;
Int_t nrc;
cout << "give a number : ";
cin >> nr;
cout << "number 1 is : " << nr << endl;
cout << "give another number : ";
cin >> nrb;
cout << "number 2 is : " << nrb << endl;
}
There is a problem. If a run the macro from the controlbar the second
number isn't stored right. If I run exp.c from the command line, everything
works fine.
What am i missing here ?
output from ROOT :
root [0] .x barexp.c
root [1] Warning: File "iostream.h" already loaded
give a number : 34
number 1 is : 34
give another number : 45
number 2 is : 5
(int)4
root [2] Warning: File "iostream.h" already loaded
give a number : 345
number 1 is : 345
give another number : 346
number 2 is : 46
(int)3
root [3] .x exp.c
Warning: File "iostream.h" already loaded
give a number : 345
number 1 is : 345
give another number : 346
number 2 is : 346
root [4]
at root[1] and root[2] I execute exp.c from the controlbar, at root[3] I
execute exp.c from the command line.
thanx for any help,
Rene Scholte
