[Qt-interest] Custom type in a list?

[Peter]

Hi, I understand how to set up a custom type and store it in a QVariant
after looking at this http://qt.nokia.com/doc/4.5/tools-customtype.html

However, I am stuck as I need to store and retrieve a list of custom types
and am unsure of what I am doing wrong.

Here is an example:

//custom type

class CustomType

{

public:

  CustomType();

  CustomType(QString& name);

  CustomType(const  CustomType& other);

  virtual ~ CustomType();


  QString name() const;


private:

  QString m_name;

};


//declaring the metatype

Q_DECLARE_METATYPE(CustomType)

Q_DECLARE_METATYPE(CustomTypeList)



I then create a custom type in another class and try to save and restore the
state:

typedef QList<CustomType> CustomTypeList;

CustomTypeList m_customtype;


settings.setValue("CustomType", QVariant::fromValue(m_customtype));

m_customtype = settings.value("CustomType").value<CustomTypeList>();




Now, when I do this, I end up with the following error from the saveState:

QVariant::save: unable to save type 256.


Does anyone know what exactly I am doing wrong?


Cheers,

Peter.
