Dear Katharina Ehrhardt

Please send me some short example of your class to reproduce the problem.

Mean time, I would advice you to read some comment explaining how to create the RootCint Dictionary in ROOT/Qt env.

Thank you.

Best regards

Subject: [ROOT] Problem creating dictionaries of classes which contain Qt-class-members  

Hi all
I've encountered a problem in creating dictionaries for header files which include a Qt header file.

I'm especially unhappy with the line:#error "Qt has not been ported to this OS - talk to qt-bugs_at_trolltech.com <mailto:qt-bugs_at_trolltech.com> "

and my header file looks like:
#include <qstring.h>
#include <TObject.h>

using namespace std;
class mySmallClass:public TObject
{
 private:
  QString name; //!
  int data;
 public:
  mySmallClass(const QString& n="",int d=0);   ~mySmallClass();
  int getData()const;
  QString getName()const;
  void setData(int d);
  ClassDef(mySmallClass,2)
};
