Hi all,

I'm trying to create a Custom Data model with some functions available through the QML code. Here is header file:

#ifndef XMLDATAMODEL_HPP
#define XMLDATAMODEL_HPP

#include <QObject>
#include <QString>
#include <QVariant>
#include <QMetaType>

#include <bb/cascades/QListDataModel>
#include <bb/data/XmlDataAccess>
#include <bb/cascades/GroupDataModel>
#include <bb/cascades/DataModel>

class XmlDataModel: public bb::cascades::DataModel{

public:
	XmlDataModel();
    virtual ~XmlDataModel();

    // Required interface implementation
    virtual int childCount(const QVariantList& indexPath);
    virtual bool hasChildren(const QVariantList& indexPath);
    virtual QVariant data(const QVariantList& indexPath);

public:

	Q_INVOKABLE
	void load(const QString& file_name);

	Q_INVOKABLE
	void setHeaderName(const QString& headerName);

private:
	QVariant *m_sourceList;
	QString *m_headerName;

};

#endif

 And this is the QML implementation:

onCreationCompleted: {
        console.log("main.qml loaded");

        _model.setHeaderName("hello");
    }

 But when the QML code try to execute the setheaderName function, I get htis error :

TypeError: Result of expression '_model.setHeaderName' [undefined] is not a function.

 i the _model is accessible by the QML code, but I don't know why I can not execute my own functions...

Can anybody help me??

Make it a Q_OBJECT:

class XmlDataModel: public bb::cascades::DataModel{
  Q_OBJECT
  ...

If I do this, I get this error when compiling:

 undefined reference to `vtable for XmlDataModel'

I had this, try clean and build manually.

It works now.

Thanks!!
