Hi there,

Well I have three little problems that I list below:

a) Can the new GUIs be used in Windos 95 ? I tried to use there a program
   that works on a HP, but in W95 it does not link. There are some 
   undefined static class members of TGxxxx classes.

b) I tried to take a look into the event display code of Pasha Murat but I
   could only find the linkdef header in the tar file...

c) I want to print a class with the iostream << operator in CINT. This is
   what I tried to do

====>  Ptest.h <======
#ifndef __PTEST_H__
#define __PTEST_H__

#include <iostream.h>
#include <TObject.h>


class Ptest : public TObject {
   private:
      int    value;
      
   public:
      Ptest(int x=0) { value=0; }
      ~Ptest() {}

      void prt (ostream &os);
      friend ostream& operator<< ( ostream& , Ptest& );

      ClassDef(Ptest,1) // Ptest class
};

ostream& operator<< ( ostream& , Ptest& );
#endif
       
====> Ptest.cxx <=======
#include "Ptest.h"

ClassImp(Ptest)


void   Ptest::prt(ostream &os) {
   os << "My value is: " << value << endl;
}

ostream& operator<< ( ostream &os , Ptest &t ) {
   t.prt(os);
   return os;
}

====> Ptest_Linkdef.h <=====
#ifdef __CINT__

#pragma link off all globals;
#pragma link off all classes;
#pragma link off all functions;


#pragma link C++ class Ptest;

#pragma link C++ function operator<<(ostream &, Ptest &);

#endif


As it is rootcint gives the following error message:

Error: Unexpected EOF G__fgetstream():2 FILE:Ptest_LinkDef.h LINE:13
Advice: You may need to use +P or -p option
Error: Unexpected EOF G__fgetc() FILE:Ptest_LinkDef.h LINE:13
Advice: You may need to use +P or -p option

Now, if I comment out the line

#pragma link C++ function operator<<(ostream &, Ptest &);

rootcint does not complain but, after loading the shared lib. with my class,

	 root> Ptest xx(4);
         root> cout << xx;

does not print anything.

Am I missing anything ? Is it the correct way to do it ?

	     Thanks,


				Carlos
