connecting issue with QAbstractItemModel

[dave_mm0]

Hey,

I have a QListView from which I obtain a QAbstractItemModel with list->model();

After this, I want to connect the dataChanged signal to a custom QObject of mine:

if( QObject::connect(model, SIGNAL(dataChanged (const QModelIndex , const QModelIndex ) ),
						customObject_,SLOT(onText(const QModelIndex , const QModelIndex )) ) )
						Proxy::write("SIGNAL SLOT connection successful");
					else
						Proxy::write("SIGNAL SLOT connection ERROR");

if( QObject::connect(model, SIGNAL(dataChanged (const QModelIndex , const QModelIndex ) ),
						customObject_,SLOT(onText(const QModelIndex , const QModelIndex )) ) )
						Proxy::write("SIGNAL SLOT connection successful");
					else
						Proxy::write("SIGNAL SLOT connection ERROR");

To copy to clipboard, switch view to plain text mode 

here is my custom object:

class CustomObject : public QObject
{
	Q_OBJECT
 
public:
	CustomObject (QObject *parent);
	~CustomObject ();
 
public slots:
	void onText(const QModelIndex & topLeft, const QModelIndex & bottomRight );
 
private:
 
};

class CustomObject : public QObject
{
	Q_OBJECT

public:
	CustomObject (QObject *parent);
	~CustomObject ();

public slots:
	void onText(const QModelIndex & topLeft, const QModelIndex & bottomRight );

private:
	
};

To copy to clipboard, switch view to plain text mode 

what am I doing wrong? I have a cout in the onText function, but nothing is ever printed when the QListView is Changed.

have you made sure the connection succeeds?

yes the QObject::connect call returns true

What kind of model is this?
