Move items in a QSortFilterProxyModel

[volcano]

I have a tableview with takes a qsortfilterproxymodel and is filtered by a particular name.

I have subclassed the qsortfilterproxymodel

class FilterProxyModel : public QSortFilterProxyModel
{
	Q_OBJECT
public:
	FilterProxyModel(QObject *parent = 0);
 
	void moveUp( const int itemIndex);
	void moveDown( const int itemIndex);
};

class FilterProxyModel : public QSortFilterProxyModel
{
	Q_OBJECT
public:
	FilterProxyModel(QObject *parent = 0);

	void moveUp( const int itemIndex);
	void moveDown( const int itemIndex);
};

To copy to clipboard, switch view to plain text mode 

and here's the implementation

FilterProxyModel ::FilterProxyModel (QObject *parent) :
	QSortFilterProxyModel(parent)
{
 
}
 
void FilterProxyModel ::moveUp(const int itemIndex)
{
	if(itemIndex > 0 && itemIndex < rowCount())
	{
		beginMoveRows(QModelIndex(), itemIndex, itemIndex, QModelIndex(),
					  itemIndex - 1);
		moveRow(QModelIndex(), itemIndex, QModelIndex(), itemIndex - 1);
		endMoveRows();
	}
}
 
void FilterProxyModel ::moveDown(const int itemIndex)
{
	if(itemIndex >= 0 && itemIndex < rowCount() - 1)
	{
		beginMoveRows(QModelIndex(), itemIndex, itemIndex, QModelIndex(),
					  itemIndex + 2);
		moveRow(QModelIndex(), itemIndex, QModelIndex(), itemIndex + 2);
		endMoveRows();
	}
}

FilterProxyModel ::FilterProxyModel (QObject *parent) :
	QSortFilterProxyModel(parent)
{

}

void FilterProxyModel ::moveUp(const int itemIndex)
{
	if(itemIndex > 0 && itemIndex < rowCount())
	{
		beginMoveRows(QModelIndex(), itemIndex, itemIndex, QModelIndex(),
					  itemIndex - 1);
		moveRow(QModelIndex(), itemIndex, QModelIndex(), itemIndex - 1);
		endMoveRows();
	}
}

void FilterProxyModel ::moveDown(const int itemIndex)
{
	if(itemIndex >= 0 && itemIndex < rowCount() - 1)
	{
		beginMoveRows(QModelIndex(), itemIndex, itemIndex, QModelIndex(),
					  itemIndex + 2);
		moveRow(QModelIndex(), itemIndex, QModelIndex(), itemIndex + 2);
		endMoveRows();
	}
}

Here's how the model implemented

m_Model = new FilterProxyModel(this);
m_Model ->setSourceModel(partiesModel);
m_Model ->setFilterRegExp(QRegExp("party", Qt::CaseInsensitive, QRegExp::FixedString));
m_Model ->setFilterKeyColumn(PartyModel::Action);

m_Model = new FilterProxyModel(this);
m_Model ->setSourceModel(partiesModel);
m_Model ->setFilterRegExp(QRegExp("party", Qt::CaseInsensitive, QRegExp::FixedString));
m_Model ->setFilterKeyColumn(PartyModel::Action);

I want to move the items using a push button, when i call the function the move doesn't happen. Could you tell me what I'm missing?

Check return value of moveRow() and shows that function.

I will write a custom implementation of the move and try
