QTList Custom class Serlization

[saravanadel]

Hi,

I have a problem in qt list serialization.

I am getting error no match for operator '>>' in s '>>' t (from qdatastream.h). I also tried declaring meta but not use.

class CustomClass
{
QString name;
QDataStream &operator<<(QDataStream &out, const CustomClass& myClass)
 {
  out<<myClass.name;
  return out;
 }
 QDataStream &operator>>(QDataStream& in,CustomClass& myClass)
 {
  in>>myClass.name;
  return in;
 }
}
Q_DECLARE_METATYPE(CustomClass*);
 
class CustomClass2
{
QList<CustomClass> list;
QDataStream &operator<<(QDataStream &out, const CustomClass2& myClass)
 {
  out<<myClass.list;
  return out;
 }
 QDataStream &operator>>(QDataStream& in,CustomClass2& myClass)
 {
  in>>myClass.list;
  return in;
 }
};

class CustomClass
{
QString name;
QDataStream &operator<<(QDataStream &out, const CustomClass& myClass)
 {
  out<<myClass.name;
  return out;
 }
 QDataStream &operator>>(QDataStream& in,CustomClass& myClass)
 {
  in>>myClass.name;
  return in;
 }
}
Q_DECLARE_METATYPE(CustomClass*);

class CustomClass2
{
QList<CustomClass> list;
QDataStream &operator<<(QDataStream &out, const CustomClass2& myClass)
 {
  out<<myClass.list;
  return out;
 }
 QDataStream &operator>>(QDataStream& in,CustomClass2& myClass)
 {
  in>>myClass.list;
  return in;
 }
};

To copy to clipboard, switch view to plain text mode 

Without the meta tag declaration 'Q_DECLARE_METATYPE(CustomClass*);'. it says no match for operator '>>' and '<<' myClass.list

Please help.
